These installation steps use the Apache web server on Linux as an example. TWiki should run on other web servers and Unix systems as well. **_Note:_** These installation notes assume user `nobody` for all files manupulated by the cgi scripts (executed by the web server), and user `twiki` for all other files. You need to replace user `nobody` with an other user in case the web server executes the script with a different user ( default for Debian is `www-data` ). Also, you can substitute user `twiki` with your own user name. - Request the TWiki distribution (in Unix ZIP format) from . - Create directory `/home/httpd/twiki` and unzip the TWiki distribution to this directory. - 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/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` .
**_Note:_** _The `ScriptAlias` **must** come before the `Alias` in Apache, otherwise it will fail to correctly set up `/twiki/bin/` , due to the fact that it sees that as being just another subdirectory of the `/twiki/` alias. ([[MichaelBrooks]] 30 Jun 2000)_
- Here are example `httpd.conf` entries: ScriptAlias /twiki/bin/ "/home/httpd/twiki/bin/" Alias /twiki/ "/home/httpd/twiki/pub/" Options +ExecCGI SetHandler cgi-script Allow from all Options FollowSymLinks +Includes AllowOverride None Allow from all - Restart Apache by `/etc/rc.d/rc5.d/S85httpd restart` . - Test if the `twiki/bin` directory is cgi-enabled: - Enter the URL of that directory into your browser ( `http://your.domain.com/twiki/bin` ). It is not set correctly as cgi-bin in case you get something like `"Index of /twiki/bin"` . It is OK if you get a message like `"Forbidden. You don't have permission to access /twiki/bin/ on this server."` - Execute the `testenv` script from your browser ( `http://your.domain.com/twiki/bin/testenv` ). It should show a table of all CGI environment variables. - Make sure PERL and the PERL CGI library is installed on your system. Default location of PERL executable is `/usr/bin/perl` . In case PERL is installed in a different location, the first line of all perl scripts in the `twiki/bin` directory need to be changed (alternatively you can create a symbolic link from `/usr/bin/perl` ). - 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. - The scripts execute as `nobody` . Set the file permission of all Perl scripts in the `twiki/bin` directory as executable to `-rw-r-xr-x` . - Set the file permission of all files below `twiki/data` to 666 ( `-rw-rw-rw-` ). - Set the file permission of the `twiki/data` directory and all its subdirectories to 777 ( `drwxrwxrwx` ). - Set the file permission of the `twiki/pub` directory to 777 ( `drwxrwxrwx` ). - Edit the file `twiki/bin/wikicfg.pm` and set the variables at the beginning of the file to your needs. - Make sure RCS is installed. In case RCS is not in the `path` environment variable, add it to `path` . Alternatively, add the full path name to the `rcs, ci, co, rlog, rcsdiff` commands in the variables of `twiki/bin/wikicfg.pm` . - Point your browser at and start wiki-ing away! - Note in case cgi user is **_not_** `nobody` : The `*,v` RCS repository files delivered with the installation package are locked by user `nobody` . In case the user is different (e.g. `www-data` ), it is not possible to check in files, this has the effect that the topic version number does not increase when saving a topic. In this case you need to unlock all repository files and lock them as user `www-data` (check the rcs man pages), or simply delete all the repository files. - Security issue: Directories `twiki/data` , `twiki/templates` and all its subdirectories should be set so that they are **not** visible as a URL. (Alternatively, move the directries to a place where they are not visible, and change the variables in `twiki/bin/wikicfg.pm` accordingly) - Enable email notification of topic changes, [(3)](TWikiDocumentation#notification) has more. - Add the [PoweredByTWikiLogo](http://TWiki.SourceForge.net/cgi-bin/view/Main/PoweredByTWikiLogo) if TWiki is installed on a public web server. - Optional: You can add new rendering rules or new %variables%. To insure an easy upgrade of TWiki it is recommended to do this customization in `twiki/bin/wikicfg.pm` , not `twiki/bin/wiki.pm` . - Optional: If you are on a public server and you would like to authenticate users: - Rename file `.htaccess.txt` in the `twiki/bin` directory to `.htaccess` and change it to your needs. For details consult the HTTP server documentation (for Apache server: [[1]](http://www.scs.nevada.edu/cs/documents/web/htaccess.html), [[2]](http://www.mcs.kent.edu/system/web_help/htaccess/introduction.html), [[3]](http://www.apache.org/docs/mod/directives.html)). **_Note:_** In case `.htaccess` does not have any effect you need to enable it: Add "AllowOverride All" to the Directory section of `access.conf` for your `twiki/bin` directory. - Copy the [[TWikiRegistrationPub]] topic to [[TWikiRegistration]]. You can customize the topic if needed. **_Note:_** You can delete or add new input variables to the registration form. The `name=""` parameter of the input tags must start with: `"Twk0..."` (if this is an optional entry), or `"Twk1..."` (if this is a required entry). This will ensure that the fields are processed correctly. - Optional: You can automatically generate usage statistics for all webs. To enable this: - Make sure variable `$doLogTopicView, $doLogTopicSave and $doLogTopicUpload` in `wikicfg.pm` are set. This will generate log entries in file `twiki/data/log.txt` . - Topic [[WebStatistics]] must be present in all webs where you want to have statistics. You can use the topic in the Main web as a template. - Call the `twiki/bin/statistics` script from a cron job, once a day is recommended. This will update the [[WebStatistics]] topics in all webs. - **_Attention:_** The script must run as the same user as the CGI scripts are running, which is user `nobody` on most systems. Example crontab entry:
`0 0 * * * (cd /path/to/TWiki/bin; ./statistics >/dev/null 2>&1)` - There is a workaround in case you can't run the script as user `nobody` : Run the utility `twiki/bin/geturl` in your cron job and specify the URL of the `twiki/bin/statistics` script as a parameter. Example:
`0 0 * * * (cd /path/to/TWiki/bin; ./geturl mydomain.com /urlpath/to/TWiki/bin/statistics >/dev/null 2>&1)` - The `twiki/bin/statistics` script can also be executed as a CGI script, just enter the URL in your browser. Examples: - Update current month for all webs:
`http://mydomain.com/twiki/bin/statistics` - Update current month for Main web only:
`http://mydomain.com/twiki/bin/statistics/Main` - Update January 2000 for Main web:
`http://mydomain.com/twiki/bin/statistics/Main?logdate=200001` - To create a new web: - Use a name for the web consisting of characters `A..Z` , `a..z` but **not** in [[WikiNotation]]. - Create a new template directory under `twiki/templates` . - Create a new data directory under `twiki/data` and check the file permission of the directory. - Copy the files `WebHome.txt` , `WebPreferences.txt` , `WebNotify.txt` , `WebSearch.txt` and `WebStatistics.txt` from the `twiki/data/Main` 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` ). Hint: You can set permissions of `.txt` and `.txt,v` files to `-rw-rw-rw-` and then edit the topic using your browser, RCS will restore the file permission correctly when saving the topic. - Add the new web to the web list (on top of each topic) by editing the site-level preferences [[TWikiPreferences]]: - Add the new web to the WIKIWEBLIST variable. - Add the new web to the web table (at the bottom of each [[WebHome]] topic) by editing the [[TWikiWebsTable]] topic. - Change the web preferences by editing the WebPreferences topic of the new web: - Set the WEBBGCOLOR variable to a color of your taste. The number represents the unique color for the web (consult an HTML book for colors.) - Customize the WEBTOPICLIST variable to contain the web specific links you prefer. - Optional: Set the WEBCOPYRIGHT variable to have a web-specific copyright text (at the bottom of each topic). - If needed, create customized templates in the new templates directory. (Non existing templates are inherited from `twiki/templates` ) - If you want to use a category table, copy the three files `twikicatitems.tmpl` , `twikicatedit.tmpl` and `twikicatview.tmpl` from the `twiki/templates/Know` directory to the new templates directory, and customize it. The TWiki Category Table section has more. - In case you want usage statistics for this web: Copy file `WebStatistics.txt` from the `twiki/data/Main` directory to the new data directory. Edit topic WebStatistics in the new web and delete old usage entries. Here are contents of directories with file permissions.
