Installation Guide Part 1

This guide describes the steps for manually installing Foswiki, with specific steps for installations on Linux with the Apache web server. If you are using a different web server or operating system, in addition to reviewing this document, check any additional information specific to your platform at Foswiki:Support.SupplementalDocuments. Foswiki:Support.SupplementalDocuments also has information for other scenarios, such as shared web hosting environments.

These installation instructions are also available online at Foswiki:System.InstallationGuide, and are available within your Foswiki installation at System.InstallationGuide (the InstallationGuide topic in the System web).

For information on upgrades, please also refer to Foswiki:System.UpgradeGuide. A static HTML version of this document, UpgradeGuide.html, is included in the root of your Foswiki distribution.

Initial Installation

System Requirements

Please see the section "Foswiki system requirements" for the server and client requirements to run Foswiki, including the Perl modules required on the server. If you need to install any Perl libraries from CPAN for use by Foswiki, see Foswiki:Support.HowToInstallCpanModules for more information.

Preparing to install

Before attempting to install Foswiki, you are encouraged to review the Foswiki:System.AdminSkillsAssumptions. This guide assumes the person installing Foswiki has a basic knowledge of server administration on the system on which Foswiki is to be installed. While it is possible to install Foswiki with FTP access alone (for example, on a hosted site), it is tricky and may require additional support from your hosting service (for example, in setting file ownership and installing missing perl CPAN libraries).

If you are upgrading from a previous Foswiki version or from a TWiki installation, please refer to Foswiki:System.UpgradeGuide. A static HTML version of this document, UpgradeGuide.html, is included in the root of your Foswiki distribution.

Verify that your server meets the Foswiki system requirements, including having the minimum required Perl version and all required Perl modules installed. If you need to install any Perl libraries from CPAN for use by Foswiki, see Foswiki:Support.HowToInstallCpanModules for more information.

If you need help, feel free to ask a question in the Foswiki:Support web or on Foswiki:Community.InternetRelayChat (irc.freenode.net, channel #foswiki).

Basic installation: getting Foswiki up and running

To install Foswiki, complete the following steps:

  1. Download and unpack the Foswiki distribution.
  2. Set the file and directory permissions for the installation.
  3. Configure the locations of the Perl executable and the Foswiki modules.
  4. Configure the web server.
  5. Configure Foswiki.
  6. Enable authentication of users (if desired).
  7. Define the administrator users.

Download and unpack the Foswiki distribution

Download the Foswiki distribution from http://foswiki.org/Download

Unpack the distribution file: Change to the directory where you want to place the Foswiki directory. Unzip or untar and gunzip the distribution; a new subdirectory called Foswiki-VERSION will be created. You can rename this subdirectory to a shorter name. For the rest of this document, this subdirectory is assumed to be at /path/to/foswiki.
  • Note: Foswiki does not support directory paths that contain spaces, so ensure that all of its directory paths do not contain any spaces (particularly on Windows).

If you do not have shell access to your web server host, see the section "Uploading the Foswiki distribution to your web server host".

(Not applicable on Windows) Set the file and directory permissions for the installation

Set up access file and directory rights, as well as file ownership, as required by your web server configuration so that the web server user (the user used by the web server to run CGI programs) can read and write within the foswiki directory tree.

Note: for more information on the appropriate permissions to ensure security for your Foswiki data, see Foswiki:Support.SecuringYourSite.

The default file and directory access permissions as set by the distribution define a reasonable security level that will work for many types of installations, including shared hosting. Nonetheless, you should verify that the web server user has read access to all files and directories beneath the foswiki directory, and execute access for all directories. Also verify that the data and pub directories and all the subdirectories and files beneath them allow write access for the web server user.
  • Warning: Do not just run a chmod -R 770 foswiki. Providing execute access to all files is potentially dangerous. This is a common mistake made by Foswiki installers. See Foswiki:Support.SettingFileAccessRightsLinuxUnix for a sample set of Unix commands to set the file and directory permissions.

It is possible to define tighter access permissions than the default ones; how tight they should be depends on your web server environment and local needs. Typically you should limit all access from others if the web server machine has login access for users other than root and the web server administrator. For a dedicated web server that just runs Foswiki and has limited login access, the default access permissions have a good safety level.

If you have root user permissions, then for additional security, you can change the ownership of the foswiki directory tree to the web server user, using the command chown -R user:group /path/to/foswiki. The web server username varies in different installations; here are some sample commands for various Linux distributions:
  • RedHat, Fedora, CentOS, Gentoo, Mandriva : chown -R apache:apache /path/to/foswiki
  • debian/Ubuntu/Kubuntu : chown -R www-data:www-data /path/to/foswiki
  • Suse : chown -R wwwrun:www /path/to/foswiki

If Foswiki stops working after you applied a change in access permissions and you wish to restore the original permissions, run the Unix commands located at Foswiki:Support.SettingFileAccessRightsLinuxUnix.

(optional - required on Windows ) Configure the locations of the Perl executable and the Foswiki modules

If you are running on a Linux system with Perl found in /usr/bin/perl then this step is not required. This step is required on Windows installations.

The easiest way to fix up the bin scripts is to run the tools/rewriteshebang.pl script. If the Perl interpreter is in the default execution path, follow these steps:

cd /path/to/foswiki/tools
perl -I ../lib rewriteshebang.pl

or for Windows users:

cd C:\path\to\foswiki\tools
perl -I ..\lib  rewriteshebang.pl

The script will determine the location of the Perl interpreter and will prompt to update both the bin and tools scripts in a single step. The changed files will be reported, and it is safe to rerun the script.

If the perl command does not work from the command line, then you need to find the location of your system's Perl interpreter. Insert the path to Perl in the first line of the rewriteshebang script. For example:

cd C:\path\to\foswiki\tools
C:\path\to\perl -I ..\lib  rewriteshebang.pl

(optional) Configuration of a script suffix for the perl scripts

Some web servers require a special extension on perl script files (e.g. .cgi or .pl). This is not normally required with the Apache web server, though some hosted web servers are configured to require it. If the documentation for your web server indicates that a special extension is necessary, rename all the executable scripts in bin; that is, rename bin/view to bin/view.pl, and so on. When configuring Foswiki (see the section "Configure Foswiki"), set the ScriptSuffix option to the special extension.

(optional) Configuration for non-standard library locations

A standard Foswiki install has the directories bin/ and lib/ located under the Foswiki installation directory. If you have moved these directories, or if your system requires changes to the default Perl libraries, then this step is required.

Create the file LocalLib.cfg located at bin/LocalLib.cfg
  • In the bin directory, copy the template file LocalLib.cfg.txt to LocalLib.cfg. Make sure the ownership and access rights of the copy are the same as LocalLib.cfg.txt.
  • Edit bin/LocalLib.cfg so that $foswikiLibPath is set to the absolute file path of your lib directory. For example: /path/to/foswiki/lib.
  • If you need to install additional CPAN modules, but can't update the main Perl installation files on the server, you can set $CPANBASE to point to your personal CPAN install. Don't forget that the web server user has to be able to read those files as well.

Configure the web server

First choose the best configuration method for your web server. With Apache, there are two ways to configure it: a config file included from httpd.conf or .htaccess files.
  • Apache config file: The recommended method is using a config file. With a config file you can put the entire Foswiki configuration in ONE file (typically named foswiki.conf). Performance is much better with a config file, and one file gives the best overview and ensures that you get a safe installation . However to use a config file you need root or sudo access to stop and start Apache. The Foswiki apache config file can be included from the main Apache config file. (Typically httpd.conf or apache.conf depending on your distribution). However most distributions have a directory from which any file that ends with .conf gets included when you restart Apache (Example RedHat/Fedora/Centos: /etc/httpd/conf.d, Gentoo: /etc/apache2/vhost.d ). If you use a virtual host setup in Apache you should include the foswiki.conf file from inside the desired virtual host config in your Apache configuration.
  • .htaccess files: This method should only be used when you cannot use a config file. Performance is slower as Apache must search through all applicable directories for any .htaccess files on each page access. Normally this is the only way to control Apache in a shared host environment where you have no root or sudo privileges.

If you are using a config file:
  • The easiest and best way is to use the Foswiki:Support.ApacheConfigGenerator tool to generate a safe, working config file for your Foswiki installation, based on the options you choose in the tool.
  • If you can't use the online configuration generator, a sample config file called foswiki_httpd_conf.txt can be found in the root of the foswiki installation.
  • Ensure that web access is denied to all Foswiki subdirectories other than bin and pub.
  • Ensure there is either a ScriptAlias directive for the bin subdirectory, or an Alias directive with SetHandler cgi-script and Options ExecCGI directives for the bin subdirectory, so that the bin scripts will be executed by Apache.
  • Note: you must restart Apache after making changes to your config files for the changes to take effect.

If you are using a .htaccess file:
  • In the root of the foswiki installation, there are sample .htaccess files for various subdirectories in your installation. Each file has help text explaining how to modify it for your configuration. For more information, see Foswiki:Support.SupplementalDocuments.
    location and name of sample .htaccess file copy sample file to the following location
    foswiki/root-htaccess.txt foswiki/.htaccess
    foswiki/bin-htaccess.txt foswiki/bin/.htaccess
    foswiki/pub-htaccess.txt foswiki/pub/.htaccess
    foswiki/subdir-htaccess.txt foswiki/<subdir>/.htaccess
    Copy to all other subdirectories below foswiki, including data, lib, locale, templates, tools, working. Copy to any other directories except for bin and pub addressed above.
  • Ensure that web access is denied to all Foswiki subdirectories other than bin and pub. The sample .htaccess files show how to configure Apache appropriately. It is important to verify that none of these directories can be directly accessed.
  • Ensure that the foswiki/bin/.htaccess files contains the line SetHandler cgi-script so that all scripts in the bin directory will be executed by Apache.
  • Note: On Linux systems, files named with the leading "." like .htaccess are hidden files and will not be listed unless using the -a option, ex. ls -la

Turn off any kind of PHP, Perl, Python, Server Side Includes, or other software execution mechanisms supported by your web server in the pub directory. For example, most Linux distributions have a default Apache installation with PHP and server side include (SSI) enabled. This would allow PHP scripts uploaded as attachments to be executed, which is a security risk, so it should be disabled in the Apache configuration with php_admin_flag engine off.

Different script execution mechanisms are disabled in different ways; see your web server configuration and documentation for more details.

Protect the configure script!
You should never leave the configure script open to the public. Limit access to the bin/configure script to either localhost, an IP address or a specific user using basic Apache authentication. The Foswiki:Support.ApacheConfigGenerator lets you setup who has access to the configure script. Also see the foswiki-httpd-conf.txt or bin/.htaccess.txt file for an example of the setting required to protect the configure script.

To limit access to a particular user, set up a .htpasswd file that contains the user name and password that Apache will use to authenticate the user:
  • Caution! Do not follow these steps on an existing Foswiki .htpasswd file. It will destroy the email addresses stored in that file! If the file already exists, you can choose an existing user for access to configure.
  • Change to the foswiki/data directory.
  • Issue the command htpasswd -c .htpasswd <username>, where <username> is the name of the user you will use to access the configure script. Choose the username with care: the username cannot be an existing login name for your Foswiki installation, nor can it be used later on to register in Foswiki. Enter a password when prompted.

All of the above methods - Sample configuration files, Foswiki:Support.ApacheConfigGenerator and sample .htaccess files, all include example settings to protect the configure script with a password. The critical section looks something like:
<FilesMatch "configure.*">
    SetHandler cgi-script
    Order Deny,Allow
    Deny from all
    # List of IP addresses allowed to access configure
    Allow from 127.0.0.1 192.168.1.10
    # specify username used on the "htpasswd" command above
    Require user someuserid
    # Set to "Any" to allow IP -or- userid,  set to "All" to require both match
    Satisfy Any
    ErrorDocument 401 default
</FilesMatch>

Note: In addition to any web server security protection that you have set up, when saving any configuration settings for the first time on the configure web page, you will be prompted to set a configuration password. This password must be entered on all subsequent configuration changes, and is also used to log in via the internal admin link (see the section "Define the administrator user(s)"). Even after a configure password has been set, access to the configure page should still be restricted by the web server, in order to avoid revealing internal information to potential attackers.

Tip: You do not have to use the same password file for both Configure and for Foswiki user registration. If you use a separate file, you can create it using the htpasswd commmand and complete segregate configure access from Foswiki access. This is probably safer, but does not allow users to change their configure password using Foswiki services. The password file has to be manually maintained..
  1. Generate an alternate password file to protect configure. htpasswd -c -s /path/to/data/.htpasswd-admin configuserid
  2. Add / modify and delete this alternate file using the htpasswd command. Don't mix them up and use htpasswd on the Foswiki .htpasswd file!
  3. Edit the foswiki apache configuration and modify the block (shown above) that protects the configuration command. Add or modify the following statements in the block. Don't remove the other statements!
<FilesMatch "configure.*">
        AuthType Basic
        AuthName "admins only"
        AuthUserFile /path/to/data/.htpasswd-admin
        # Changing the Require user to Require valid-user allows any ID in the
        # file access to configure!
        Require valid-user
</FilesMatch>
For more information, refer to Foswiki:Support.ProtectingYourConfiguration.

Configure Foswiki

Run the configure script from your browser: enter http://yourdomain/url/to/foswiki/bin/configure into your browser address bar.
  • When you access the configure web page for the first time, you can only edit the section General Path Settings. Make any required changes, and save the settings, whether or not you needed to make any changes. You will be prompted to set a password for the configure page: this password must be entered for all subsequent configuration changes, and is also used to log in via the internal admin link (see the section "Define the administrator user(s)").
    IDEA! Note: The configure password is remembered by configure, separate to web server access controls mentioned in "Protect the configure script".
  • After saving the General Path Settings, continue configuring Foswiki. Configuration items which may require further attention will be highlighted.
  • If the Foswiki installation can be accessed by more than one protocol://domain, ensure the additional alternative URLs are set in {PermittedRedirectHostUrls}.
    TIP Example: if {DefaultUrlHost} is set to https://wiki.company.com, an example {PermittedRedirectHostUrls} might contain:
    https://company.com, http://111.222.123.234
  • Setup the Mail and Proxies section. Email must be available so Foswiki can send registration emails.
    • Under the "Email General" tab, If you do not want to enable sending registration emails or want to enable it later you can uncheck {EnableEmail}. Otherwise the {WebMasterEmail} parameter must be configured.
    • Under the "Email Server" tab, you can choose 3 methods of sending email. This is explained in detail under the help text for this tab.
      • MailProgram is typically suitable on most Linux systems, and no further configuration is required.
      • If you chose either of the Net::SMPT methods, you must also configure {SMTP}{MAILHOST}. Many ISPs have introduced authentication when sending emails to fight spam so you may also have to set {SMTP}{Username} and {SMTP}{Password}.
      • Net::SMTP::SSL will encrypt the connection to the e-mail server and is required for some email services like Google's GMail.
    • Under the "Proxy" tab, if your server is behind a firewall with a proxy, and you wish to install extensions via configure, you may have to set {PROXY}{HOST} and {PROXY}{PORT}.
      ALERT! Note: A standard Foswiki installation will not allow any new registrations unless there is a working SMTP configuration
      SMTP authentication requires additional perl modules including Authen::SASL and MIME::Base64,

If there is a problem with your setup that prevents you from accessing the configure page, you can configure Foswiki manually.

Authentication

Authentication of users means their activity can be tracked, and access to your site can be controlled. This is particularly important for sites that are publicly accessible on the web. You are strongly encouraged to read System.UserAuthentication and Foswiki:Support.UserAuthenticationSupplement for further information about managing users and access controls for your Foswiki site.

The most common authentication methods used for public Foswiki installations are Template Login and Apache Login. They have the following relative advantages:
  • Template Login can be set up without any web server configuration, and users can log off without restarting the browser. As the login page is just a Wiki page, you can customize it to suit your needs.
  • Apache Login allows you to use any Apache-module based authentication scheme, such as mod_auth_ldap or mod_auth_mysql. However, as your browser is caching your login, you must restart the browser to log out.

Note that the password databases for both of these authentication mechanisms are compatible, so you can switch between them at a later date.

To make it easier to follow the instructions in this section, you can view this installation guide using your Foswiki site by entering System.InstallationGuide into the "Jump" text box. By doing this instead of using the INSTALL.html file from the distribution, you will be able to use the embedded hyperlinks to jump directly to the referenced pages.

Template Login authentication
Template Login asks for a username and password in a web page, and processes them using whatever Password Manager you choose. Users can log in and log out. Client Sessions are used to remember users. Users can choose to have their session remembered so they will automatically be logged in the next time they start their browser.

Enabling Template Login

IDEA! By default, your Foswiki installation is probably already using TemplateLogin, HtPasswdUser and TopicUserMappingContrib as the default Login, Password and user mapping options.
  1. Using configure:
    1. Navigate to the Login tab on the Security and Authentication panel. Select the Foswiki::LoginManager::TemplateLogin login manager.
    2. Navigate to the Passwords tab. Select the appropriate PasswordManager for your system - the default is Foswiki::Users::HtPasswdUser.
      HELP There is also an EXPERT configure setting {TemplateLogin}{PreventBrowserRememberingPassword} that you can set to prevent Browsers from remembering username and passwords if you are concerned about public terminal usage.
  2. Verify that registration works by registering yourself with the System.UserRegistration topic. If there are problems, try these troubleshooting tips:
    1. If you are reading this from the INSTALL.html file, you can enter System.UserRegistration into the 'Jump' box in the top right of any Foswiki page.
    2. Note: A standard Foswiki installation will not allow any new registrations unless there is a working SMTP configuration
    3. If your PasswordManager is HtPasswdUser (the default), check the .htpasswd file is being updated correctly with a new entry. If not, check {Htpasswd}{FileName} is correct (under Security and Authentication on the Password tab in configure), and that the webserver user has write permission.
  3. Create a new topic (in Sandbox web for example) to confirm that authentication works.
  4. Add users to the Main.AdminGroup. Edit the Main.AdminGroup topic in the Main web to include users that should have administrator status. Read defining adminstrator user(s) for more information.
    ALERT! This is a very important step, as users in this group can access all topics, independent of Wiki access controls.

AccessControl has more information on setting up access controls.

ALERT! Foswiki AccessControls do not protect topic attachments unless the web server has been configured to do so using the viewfile script. Visit Foswiki:Support.ApacheConfigGenerator for examples using Apache.

TIP As Template Login uses a wiki page for its login prompt, there is a great deal of flexibility in customizing the login page for your purposes.

TIP The default new user template page is in System.NewUserTemplate. The same macros get expanded as in the template topics. You can create a custom new user topic by creating the NewUserTemplate topic in Main web, which will then override the default in System web. See System.UserForm for copy instructions.

Custom registration page

You can customize the default System.UserRegistration topic by first copying System.DefaultUserRegistration to UserRegistration in Main web. This will ensure that your changes will remain intact next time you upgrade.

A couple of common fields are hidden from normal view to make the registration page as lean as possible. You can unhide those fields on the page by removing EXCLUDED_ from the INCLUDE tags) or add new ones.

New fields may also be added. The name="" parameter of the <input> tags must start with: "Fwk0..." (if this is an optional entry), or "Fwk1..." (if this is a required entry). This ensures that the fields are carried over into the user home page correctly.

Automatic Group Membership

The TopicUserMappingContrib can also enroll users into groups during registration. (Other mappers might not support this feature). Options include:
  • Automatically enrolling users in one or more groups during registration
  • Allow the user to select multiple groups from a list of eligible groups
  • Allow the user to choose only one group from a list of eligible groups
  • Don't do any group enrollment during registration.

The list of eligible groups can be generated in one of two ways:
  • Manually by configuration. This fixed list of groups will always be listed.
  • Automatically based upon CHANGE permission on the group topics.

There are two registration scenarios that apply:

Self-registration by Guest users
The actual registration will be processed by the special internal user Main.RegistrationAgent. Group topics must include an ALLOWTOPICCHANGE = Main.RegistrationAgent to be eligible for enrollment.
Registration by logged-in users
The registration form is filled out by some other logged-in user. In this case, the Main.RegistrationAgent is not used for Group updates. The current user must have ALLOWTOPICCHANGE permission for groups for them to be eligible for enrollment.
  • Caution: If an administrator registers a user with automatic group membership enabled, the new user could potentially be added to All groups. Use caution with this feature!

Note: During registration, if it turns out that the current user or Main.RegistrationAgent doesn't have permission to update the group topic, the group update will be silently skipped. The user will still be albe to register.

See DefaultPreferences#RegistrationOptions for further details. Copy the settings into Main.SitePreferences to make them active.

Apache Login authentication
With Apache Login enabled, when Foswiki needs to authenticate the user, the standard HTTP authentication mechanism is used: the browser itself will prompt for a user name and password.

The advantage of this scheme is that if you have an existing website authentication scheme using Apache modules such as mod_auth_ldap or mod_auth_mysql you can just plug in to them directly.

The disadvantage is that because the user identity is cached in the browser, you can log in, but you can't log out again unless you restart the browser.

Wiki maps the REMOTE_USER that was used to log in to the webserver to a WikiName using the table in Main.WikiUsers. This table is updated whenever a user registers, so users can choose not to register (in which case their webserver login name is used for their signature) or register (in which case that login name is mapped to their WikiName).

The same private .htpasswd file used in Wiki Template Login can be used to authenticate Apache users, using the Apache Basic Authentication support.

ALERT! Do not use the Apache htpasswd program with .htpasswd files generated by Wiki! htpasswd wipes out email addresses that Wiki plants in the info fields of this file.

IDEA! Apache Login is required for Apache-based login methods such as mod_ldap

IDEA! You can use any Apache authentication module that sets the REMOTE_USER environment variable.

To setup Apache Login, perform the following steps:

  1. Configure Apache Login. Under the Security and Authentication pane on the Login tab in configure:
    1. Select Foswiki::LoginManager::ApacheLogin for {LoginManager}.
    2. Select Foswiki::Users::HtPasswdUser for {PasswordManager}.
    3. Select Foswiki::Users::TopicUserMapping for {UserMappingManager}.
    4. Save your settings.
    5. Configure your Apache settings for HTTP authentication. Use the Foswiki:Support.ApacheConfigGenerator tool or the foswiki/bin-htaccess.txt file to set the following Apache directives on the bin scripts:
       <FilesMatch "(attach|edit|manage|rename|save|upload|mail|logon|rest|.*auth).*">
       require valid-user
       </FilesMatch>
      You can also refer to the sample foswiki_httpd_conf.txt and bin-htaccess.txt files to see how the appropriate Apache directives are specified.
  2. Verify that registration works by registering yourself with the System.UserRegistration topic. If there are problems, try these troubleshooting tips:
    1. If you are reading this from the INSTALL.html file, you can enter System.UserRegistration into the 'Jump' box in the top right of any Foswiki page.
    2. Note: A standard Foswiki installation will not allow any new registrations unless there is a working SMTP configuration
    3. If your PasswordManager is HtPasswdUser (the default), check the .htpasswd file is being updated correctly with a new entry. If not, check {Htpasswd}{FileName} is correct (under Security and Authentication on the Password tab in configure), and that the webserver user has write permission.
  3. Create a new topic (in Sandbox web for example) to confirm that authentication works.
  4. Add users to the Main.AdminGroup. Edit the Main.AdminGroup topic in the Main web to include users that should have administrator status. Read defining adminstrator user(s) for more information.
    ALERT! This is a very important step, as users in this group can access all topics, independent of Wiki access controls.

Choose an appropriate search algorithm for your Operating System

On the Store pane in configure you will find the setting {RCS}{SearchAlgorithm}.

By default it is set to Foswiki::Store::SearchAlgorithms::Forking which is what you should keep if you install Foswiki in Linux or any other Unix type operating system.

If you install Foswiki on a Windows server, using an external grep program can create problems because of limitations in the length of command lines. You may be able to run with Forking in Windows if your directory path to Foswiki is kept short (short directory names and few levels), however the recommended (safe) setting for Windows is Foswiki::Store::SearchAlgorithms::PurePerl.

Define the administrator user(s)

About Administrators

Administrators have read and write access to any topic, regardless of any access controls that have been applied to the topic or its web. The special user Main.AdminUser ships with Foswiki and is accessed using by logging in with user admin and the password established when initially saving the configuration. Don't log in with the wikiname AdminUser.

After installing Foswiki, you can also register other users that you will use to administer Foswiki. To make a user an administrator, add the WikiName for the user to the AdminGroup, defined in the Main.AdminGroup topic in your Foswiki installation.

Note that with the sudo or internal admin login, it is not necessary to add other users to the AdminGroup. However if you have more than one administrator, you may still want to do this to ensure that topic changes are attributed to a specific user instead of the default Main.AdminUser.

By adding users to Main.AdminGroup:
  • Users with Admin rights will have routine access to topics that might normally be denied.
  • These users will be unable to test or demonstrate access controls.
  • Changes made are always attributed to a unique logged in user.
  • Password sharing of the bin/configure password is not required

By using the internal admin login:
  • You don't need to grant admin rights to individual users
  • All users will be subject to access controls.
  • Changes made while using the internal admin login are attributed to Main.AdminUser
  • The "save" password for bin/configure will need to be shared among administrators

Adding users to the Main.AdminGroup
To make it easier to follow the instructions in this section, you can view this installation guide using your Foswiki site by entering System.InstallationGuide into the "Jump" text box. By doing this instead of using the INSTALL.html file from the distribution, you will be able to use the embedded hyperlinks to jump directly to the referenced pages.

To add an initial administrator to the AdminGroup, perform the following steps:

  • If you are not already logged in with your WikiName, then login.
  • Go to the Main.AdminGroup topic and select the "internal admin login" link. Login using the password you set on the configure page.
  • After logging as the internal admin, view the Main.AdminGroup topic. Follow the instructions on the page to add users to the AdminGroup. You do not need to edit the topic.

Any member of the Main.AdminGroup can add subsequent members — you do not have to use the internal admin login.

To more easily debug access control issues, you may want to have a regular Foswiki user account for daily use, and a special one that belongs to the AdminGroup that you use only for administering your Foswiki site. See System.AccessControls for more information on access controls and user groups.

Congratulations!

You now have a basic installation running. At this point you can just point your Web browser at http://yourdomain.com/url/to/foswiki/bin/view/System/InstallationGuidePart2 to proceed with further tailoring your site..

In order to keep your user, group, and site configuration information separate from the actual content of your site, it is recommended that you create a new web in which your site's pages will reside. See System.ManagingWebs for more information on Wiki webs and how to create one.

Troubleshooting

Foswiki system requirements

Low client and server base requirements are core features that keep Foswiki widely deployable, particularly across a range of browser platforms and versions. Many extensions exist which enhance and expand Foswiki's capabilities; they may have additional requirements.

Server Requirements

Foswiki is written in Perl 5, which is supported on Microsoft Windows as well as Unix and Unix-like systems (including Linux and OSX), on which it uses a number of shell commands and RCS (Revision Control System), a GNU Free Software package. It should be able to run on any server platform that meets the following requirements.

Resource Required Server Environment
Perl 5.8.8 or higher
RCS 5.7 or higher (including GNU diff)
Optional. Foswiki includes a pure Perl implementation of RCS (RcsLite) that can be used instead, at the cost of performance
GNU diff GNU diff 2.7 or higher is required when not using the all-Perl RcsLite.
Install within the PATH if not included with RCS (check version with diff -v)
Must be the version used by RCS, to avoid problems with binary attachments - RCS may have hard-coded path to diff
Other external programs fgrep, egrep
Cron/scheduler • Unix: cron
• Windows: cron equivalents
Web server Apache is well supported; for information on other servers, see Foswiki:Support.InstallingOnSpecificPlatforms.

Perl Modules

A complete list of the required and optional Perl modules can be found in lib/DEPENDENCIES.

The following CPAN modules are not shipped with Foswiki. Note that Foswiki extensions may add additional requirements. Modules marked as Required may still be optional if certain default core features are not used.

Module Required/Optional Description
CGI::Session Required Sessions support is usually required.
HTML::Entities Required Used for WYSIWYG Editing
HTML::Parser Required Used for WYSIWYG Editing
HTML::Tree Required Used by CompareRevisionAddOn.
URI Required Used for email notifications of topic changes. MailerContrib?
LWP Required Used by the Configure Extensions Installer, and for external URL based INCLUDEs
Digest::SHA Optional Required to use SHA1 password encoding, since Perl 5.9.3 part of core
Crypt::PasswdMD5 Optional Required to use Apache or Crypt MD5 password encoding, and crypt encoding on Windows
Digest::SHA1 Optional Required by the Foswiki FileCache feature
Win32::Console Optional May be required for I18N on Windows
Archive::Tar Optional Required by the Extensions Installer in configure if command line tar or unzip is not available, since Perl 5.9.3 part of core.
Archive::Zip Optional Alternative to Archive::Tar, used by the Extensions Installer if Archive::Tar and command line tar and unzip also unavailable
Net::SMTP::SSL Optional Required by Net::SMPT to send email over SSL to providers such as gmail.
Authen::SASL Optional Required by Net::SMTP if email server requires authentication.

Most of them will probably already be available in your installation. You can check version numbers with the configure script, or if you're still trying to get to that point, check from the command line like this:
perl -e 'use FileHandle; print $FileHandle::VERSION."\n"'
For more detailed dependency information, try the script dependencies_installer.pl located in the tools directory, which makes perl module installation easier. Run it with option -h to understand basics. This script requires confirmation before it actually does something.

Client Requirements

The standard installation has relatively low browser requirements:

  • XHTML 1.0 Transitional compliant
  • Cookies, if persistent sessions are required
  • Javascript, for edit/save/upload functionality
    TIP Change {ValidationMethod}{Method} from strikeone to embedded in configure to allow non-javascript browsers to edit/save/upload

CSS and Javascript are used in most skins. Some skins will require more recent releases of browsers. The default skin is tested on IE 6+, Safari, Chrome and Firefox.

You can easily select a balance of browser capability versus look and feel. Try the installed skins at System.SkinBrowser and more at Foswiki:Extensions.SkinPackage.

Uploading the Foswiki distribution to your web server host

If you cannot unpack the Foswiki distribution directly in your installation directory, you can unpack the distribution on your local computer, manually create the directory structure on your host server and upload the files as follows:
  • Using the table below, create a directory structure on your host server
  • Upload the Foswiki files by FTP (transfer as text except for the image files in pub directory.)
  • Note: Don't worry if you are not able to put the lib directory at the same level as the bin directory. You can create this directory elsewhere and configure the bin/setlib.cfg file.
    Foswiki dir: What it is: Where to copy: Example:
    foswiki start-up pages root Foswiki dir /home/smith/public_html/foswiki/
    foswiki/bin CGI bin CGI-enabled dir /home/smith/public_html/foswiki/bin
    foswiki/lib library files same level as bin /home/smith/public_html/foswiki/lib
    foswiki/locale language files dir secure from public access /home/smith/public_html/foswiki/locale
    foswiki/pub public files htdoc enabled dir /home/smith/public_html/foswiki/pub
    foswiki/data topic data dir secure from public access /home/smith/public_html/foswiki/data
    foswiki/templates web templates dir secure from public access /home/smith/public_html/foswiki/templates
    foswiki/tools Foswiki utlilities dir secure from public access /home/smith/public_html/foswiki/tools
    foswiki/working Temporary and internal files dir secure from public access /home/smith/public_html/foswiki/working

Configuring Foswiki manually (without using the configure page)

It is highly recommended that you configure Foswiki by using your browser to access the configure page. However, if you are unable to get the configure page to display (for example, if a dependency is missing), or for some reason you do not wish to use the configure page, then you can configure Foswiki manually

Perform the following steps to manually configure Foswiki:
  • Copy the file lib/Foswiki.spec to lib/LocalSite.cfg
  • Remove the # in front of the following settings, and ensure that they are set to the correct values: Note: The settings must not reference other $Foswiki::cfg variables.
       $Foswiki::cfg{DefaultUrlHost}
       $Foswiki::cfg{ScriptUrlPath}
       $Foswiki::cfg{ScriptDir}
       $Foswiki::cfg{PubUrlPath}
       $Foswiki::cfg{PubDir}
       $Foswiki::cfg{DataDir}
       $Foswiki::cfg{ToolsDir}
       $Foswiki::cfg{TemplateDir}
       $Foswiki::cfg{LocalesDir}
       $Foswiki::cfg{WorkingDir}
       $Foswiki::cfg{OS}

  • Make sure the following settings are defined:
       $Foswiki::cfg{LoginManager}
       $Foswiki::cfg{WebMasterEmail}
       $Foswiki::cfg{SMTP}{MAILHOST}
       $Foswiki::cfg{SMTP}{SENDERHOST}

  • Remove the line containing __END__ and everything following it.
