    • Set the permission of the twiki/data directory and its subdirectories so that files in there are writable by user nobody. A simple way is to chmod them to drwxrwxr-x (775) and to chown them to nobody.
    • Set the permission of the twiki/pub directory and all its subdirectories so that files in there are writable by user nobody. A simple way is to chmod them to drwxrwxr-x (775) and to chown them to nobody.
    • HELP The twiki/data/*/*.txt,v RCS repository files in the installation package are locked by user nobody. If your CGI scripts are not running as user nobody, it's not possible to check in files (you'll see that the revision number won't increase after saving a topic). In this case, you need to unlock all repository files (check the RCS man pages) and lock them with a different user, such as www-data, or delete them all - new files will be automatically created the first time each topic is edited. You have two options to change ownership of the RCS lock user:

By default, TWiki is configured to support US ASCII letters (no accents) in WikiWords, and ISO-8859-1 (Western European) characters in page contents. If that's OK for you, skip this step.

Changed:
<
<		 If your Wiki will be used by non-English speakers, TWiki can be configured for Internationalisation ('I' followed by 18 letters, then 'N', or I18N). Specifically, TWiki will support suitable accented characters in WikiWords (as well as languages such as Japanese or Chinese in which WikiWords do not apply), and to support virtually any character set in the contents of pages. NOTE: TWiki does not currently support UTF-8, so you are advised not to use this - however, improved UTF-8 support is under development.

NOTE: TWiki does not currently support UTF-8, so you are advised not to use this - however, improved UTF-8 support is under development, see TWiki:Codev/ProposedUTF8SupportForI18N.

To configure internationalisation suppport:

  1. Edit the TWiki.cfg file's Internationalisation section to set the $useLocale parameter to 1. TWiki will now use the I18N parameters set in the rest of this section.
  2. Type the Unix/Linux command locale -a to find a suitable 'locale' for your use of TWiki. A locale that includes a dot followed by a character set is recommended, e.g. pl_PL.ISO-8859-2 for Poland. Consult your system administrator if you are not sure which locale to use.
  3. In TWiki.cfg, set the $siteLocale parameter to your chosen locale, e.g. pl_PL.ISO-8859-2 for Poland.
  4. Check your setup using testenv (download the latest testenv from TWiki:Support/SupportGuidelines if possible) - this provides some diagnostics for I18N setup, and in particular checks that your locale can be used successfully.

  1. (For upgrade of TWiki I18N sites only:) If you were using TWiki:Codev.TWikiRelease01Feb2003 support for I18N, and are using Internet Explorer or Opera, you should re-configure your browser so that it sends URLs encoded with UTF-8 (supported since TWiki:Codev.TWikiRelease01Sep2004). If you are doing a new installation of TWiki, you can ignore this step - no browser reconfiguration is needed for TWiki Release 01-Sep-2004).

    • NOTE: This does not mean that TWiki supports UTF-8 as a site character set.

  1. Try out your TWiki by creating pages in the Sandbox web that use international characters in WikiWords and checking that searching, WebIndex, Ref-By and other features are working OK.

Trouble with I18N?


If international characters in WikiWords do not seem to work, and you are on Perl 5.6 or higher, you may need to set the TWiki.cfg parameter $localeRegexes to 0 - this disables some features but enables TWiki to work even if your system has locales that do not work. Then, set the $upperNational and $lowerNational parameters to the valid upper and lower case accented letters for your locale.

If international characters in WikiWords aren't working, and you are on Perl 5.005 with working locales, keep $useLocale set to 1 and set $localeRegexes to 0, then set $upperNational and $lowerNational - if testenv generates the lists of characters for you, your locales are working so there is no need to set $localeRegexes to 0 in this case.

      • Alternatively, you might try creating a file twiki/bin/.htaccess that contains the single line SetHandler cgi-script, which tells Apache to treat all files in this directory as CGI scripts.

  • Set the file permission of all Perl scripts in the twiki/bin directory as executable to -rwxr-xr-x (755).
  • To be able to edit the Perl scripts and .tmpl files it is necessary to chown and chgrp -R twiki so all the files have the owner you want.
  • HELP This Guide assumes user nobody ownership for all files manipulated by the CGI scripts (executed by the Web server), and user twiki for all other files. You can:
    • replace nobody with another user if your server executes scripts under a different name (ex: default for Debian is www-data).
      • TIP HINT: Run the testenv script from your browser: http://yourdomain.com/twiki/bin/testenv. It will show you the user name of the CGI scripts, a table listing all CGI environment variables, and a test of your twiki/lib/TWiki.cfg configuration file (you'll configure that in a minute).

Step 4: Internationalisation Setup (Optional)

By default, TWiki is configured to support US ASCII letters (no accents) in WikiWords, and ISO-8859-1 (Western European) characters in page contents. If that's OK for you, skip this step.

If your Wiki will be used by non-English speakers, TWiki can be configured for Internationalisation ('I' followed by 18 letters, then 'N', or I18N). Specifically, TWiki will support suitable accented characters in WikiWords (as well as languages such as Japanese or Chinese in which WikiWords do not apply), and to support virtually any character set in the contents of pages. NOTE: TWiki does not currently support UTF-8, so you are advised not to use this - however, improved UTF-8 support is under development.

To configure internationalisation suppport:

  1. Edit the TWiki.cfg file's Internationalisation section to set the $useLocale parameter to 1. TWiki will now use the I18N parameters set in the rest of this section.

Then, set the $upperNational and $lowerNational parameters to the valid upper and lower case accented letters for your locale.

  • NOTE: You will need to do the above workaround for Windows based servers (whether using Cygwin or ActiveState Perl), since Perl locales are not working on Windows as of Feb 2004.

If international characters in WikiWords aren't working, and you are on Perl 5.005 with working locales, keep $useLocale set to 1 and set $localeRegexes to 0, then set $upperNational and $lowerNational - if testenv generates the lists of characters for you, your locales are working so there is no need to set $localeRegexes to 0 in this case. See the comments in TWiki.cfg for more information.

Step 5: Configure Site-Wide Email Preferences


  • Edit the TWikiPreferences topic in the TWiki web (by pointing your browser to http://yourdomain.com/twiki/bin/view/TWiki/TWikiPreferences) to set the WIKIWEBMASTER email address, and other email settings required for registration and WebChangesAlert to work:

      • ALERT! NOTE: In the TWiki distribution package, the twiki/data/.htpasswd.txt file contains several TWiki core team user accounts and a guest user account. You probably want to remove those accounts by deleting the entries in .htpasswd. Do not remove the guest user if you want to allow guest logins.

    1. TWiki now supports several Password file format/encoding methods for Apache. Once you know what method is used by your Appache server, you can configure TWiki to create compatible .htpasswd entries by editing the $htpasswdFormatFamily, $htpasswdEncoding and $htpasswdFilename in the TWiki.cfg file. The supported options are htpasswd:plain, htpasswd:crypt, htpasswd:sha1, htdigest:md5

    1. Copy the TWikiRegistrationPub topic to TWikiRegistration, overwriting old version of TWikiRegistration. Do that by either editing the topics in theTWiki web, or by renaming the .txt and .txt,v files in the twiki/data/TWiki directory.

TWiki runs on other web servers and Unix systems, and should be fine with any web server and OS that meet the system requirements. Official documentation for platforms other than Linux is somewhat limited, so please check the topics listed below, they include some important tips for HP-UX, Solaris, OS/390, and many other platforms.

Standard Installation

Line: 24 to 26

 ALERT! NOTE: If you don't have access to your Web server configuration files - for example, if you're installing on an ISP-hosted account, or you don't have administrator privileges on your intranet server - use the alternative Step 1 instead.

  • Create directory /home/httpd/twiki and unzip the TWiki distribution into this directory.
Changed:

<
  • The twiki/bin directory of TWiki must be set as a cgi-bin directory. Add /home/httpd/twiki/bin to file /etc/httpd/httpd.conf with only ExecCGI option.

  • The twiki/bin directory of TWiki must be set as a cgi-bin directory. Add /home/httpd/twiki/bin to file httpd.conf (typcially located in /etc/httpd/) with only ExecCGI option.

  • The twiki/pub directory of TWiki must be set so that it is visible as a URL. Add /home/httpd/twiki to file httpd.conf with normal access options (copy from /home/httpd/html ).
  • Now add ScriptAlias for /twiki/bin and Alias for /twiki to file httpd.conf .
    ALERT! NOTE: The ScriptAlias must come before the Alias, otherwise, Apache will fail to correctly set up /twiki/bin/, by treating it as just another subdirectory of the /twiki/ alias.
Line: 93 to 95

Step 2: Set File Permissions

  • Make sure Perl 5 and the Perl CGI library are installed on your system. The default location of Perl is /usr/bin/perl. If it's elsewhere, change the path to Perl in the first line of each script in the twiki/bin directory, or create a symbolic link from /usr/bin/perl.

    • IMPORTANT: On ISP-hosted accounts, Perl CGI scripts usually require a .cgi extension to run. Some systems need .pl, the regular Perl extension. Modify all twiki/bin script filenames if necessary.

    • IMPORTANT: On ISP-hosted accounts (and some intranet servers), Perl CGI scripts may require a .cgi extension to run. Some systems need .pl, the regular Perl extension. Rename all twiki/bin scripts if necessary.

  • Set the file permission of all Perl scripts in the twiki/bin directory as executable to -rwxr-xr-x (755).
  • To be able to edit the Perl scripts and .tmpl files it is necessary to chown and chgrp -R twiki so all the files have the owner you want.
  • HELP This Guide assumes user nobody ownership for all files manipulated by the CGI scripts (executed by the Web server), and user twiki for all other files. You can:

  • Edit the WebPreferences topic in each web, if necessary: set individual WEBCOPYRIGHT messages, and other preferences.
  • Enable email notification of topic changes, TWikiSiteTools has more.
  • Edit the WebNotify topic in all webs and add the users you want to notify.

  • Set the permission of all files below twiki/data so that they are writable by user nobody. A simple way is to chmod them to -rw-rw-r-- (664) and to chown them to nobody.
  • Set the permission of the twiki/data directory and its subdirectories so that files in there are writable by user nobody. A simple way is to chmod them to drwxrwxr-x (775) and to chown them to nobody.
  • Set the permission of the twiki/pub directory and all its subdirectories so that files in there are writable by user nobody. A simple way is to chmod them to drwxrwxr-x (775) and to chown them to nobody.

  • HELP The twiki/data/*/*.txt,v RCS repository files in the installation package are locked by user nobody. If your CGI scripts are not running as user nobody, it's not possible to check in files (you'll see that the revision number won't increase after saving a topic). In this case, you need to unlock all repository files (check the RCS man pages) and lock them with a different user, ex www-data, or delete them all - new files will be automatically created the first time each topic is edited. A simple way to change ownership is with a search-and-replace in all files; for example, using perl:

  • Edit the TWikiPreferences topic in the TWiki web (by pointing your browser to http://yourdomain.com/twiki/bin/view/TWiki/TWikiPreferences) to set the WIKIWEBMASTER email address, and other email settings required for registration and WebChangesAlert to work:

    • WIKIWEBMASTER should be set to the email address of the TWiki administrator
    • SMTPMAILHOST is typically set on Windows or other non-Unix/Linux systems, where sendmail or similar is not available. When this is set and the Perl module Net::SMTP is installed, TWiki will connect to this SMTP server (e.g. mail.yourdomain.com) to send email for user registration and WebChangesAlerts. If you do have a sendmail-type program, leave SMTPMAILHOST unset so that the external sendmail program is used instead (defined by $mailProgram in TWiki.cfg).
    • SMTPSENDERHOST is optional, and set to the domain name sending the email (e.g. twiki.yourdomain.com). For use where the SMTP server requires that you identify the TWiki server sending mail. If not set, Net::SMTP will guess it for you.
  • You may want to set up other TWikiPreferences later on.

Adding a New Web

To create a new web:

  1. Create a new web data directory under twiki/data and check the file permission of the directory.
    • Use a name consisting of characters A..Z , a..z but not in WikiNotation. (The name should start with one (or more) uppercase letters, but have no uppercase letters after the first group -- if it starts with a lowercase letter or is a WikiWord, some features of TWiki will not work as expected.)
  2. Copy all files from the twiki/data/_default directory to the new data directory, preserving the original files' owner, group and permissions (on Unix, use cp -p). The data files must be writable by the owner the CGI scripts are running on (usually, nobody).
    • TIP HINT: You can set permissions of .txt and .txt,v files to -rw-rw-rw- (666) and then edit the topic using your browser; RCS will restore the file permissions correctly when saving the topic.
  3. Add the new web to the web list (visible in the upper right corner of each topic) by editing the site-level preferences, TWikiPreferences:
    • Add the new web to the %WIKIWEBLIST% variable.
  4. Update the web settings by editing the WebPreferences topic of the new web:
    • Customize the %WEBTOPICLIST% variable to contain the web-specific links you prefer.
    • Set the WEBBGCOLOR variable to a color. The number represents the unique color for the web.
    • Set Plugins, access privileges, custom variables, other web-level options (ex: %WEBCOPYRIGHT% can be set for an individual web).
  5. Test the new web: view pages, create a new page.

That's it for a basic new web set-up!

Optionally, you can also:

    # -------------- Change these settings if required

    $twikiLibPath = '/some/other/path/lib';   # Path to lib directory containing TWiki.pm

You can also edit $localPerlLibPath in the setlib.cfg file if you are not root and need to install additional CPAN modules, but can't update the main Perl installation files on the server.
