To generate the `trac.cgi` script run: 9 {{{ 10 trac-admin /path/to/env deploy /path/to/www/trac 11 }}} 12 `trac.cgi` will be in the `cgi-bin` folder inside the given path. ''Make sure it is executable by your web server''. This command also copies `static resource` files to a `htdocs` directory of a given destination. 9 CGI script is the entrypoint that web-server calls when a web-request to an application is made. The `trac.cgi` script can be created using the `trac-admin <env> deploy <dir>` command which automatically substitutes the required paths, see TracInstall#cgi-bin. Make sure the script is executable by your web server. 13 10 14 == Apache web-server configuration ==11 == Apache web-server configuration 15 12 16 13 In [http://httpd.apache.org/ Apache] there are two ways to run Trac as CGI: 17 14 18 1. Use a `ScriptAlias` directive that maps a nURL to the `trac.cgi` script (recommended)19 2. Copy the `trac.cgi` file into the directory for CGI executables used by your web server (commonly named `cgi-bin`). You can also create a symbolic link, but in that case make sure that the `FollowSymLinks` option is enabled for the `cgi-bin` directory.15 1.

You can also create a symbolic link, but in that case make sure that the `FollowSymLinks` option is enabled for the `cgi-bin` directory. 20 17 21 18 To make Trac available at `http://yourhost.example.org/trac` add `ScriptAlias` directive to Apache configuration file, changing `trac.cgi` path to match your installation: 22 {{{ 19 {{{#!apache 23 20 ScriptAlias /trac /path/to/www/trac/cgi-bin/trac.cgi 24 21 }}} 25 22 26 ''Note that this directive requires enabled `mod_alias` module.''23 ''Note that this directive requires that the `mod_alias` module is enabled.'' 27 24 28 25 If you're using Trac with a single project you need to set its location using the `TRAC_ENV` environment variable: 29 {{{ 26 {{{#!apache 30 27 <Location "/trac"> 31 28 SetEnv TRAC_ENV "/path/to/projectenv" … … 34 31 35 32 Or to use multiple projects you can specify their common parent directory using the `TRAC_ENV_PARENT_DIR` variable: 36 {{{ 33 {{{#!apache 37 34 <Location "/trac"> 38 35 SetEnv TRAC_ENV_PARENT_DIR "/path/to/project/parent/dir" … … 40 37 }}} 41 38 42 ''Note that the `SetEnv` directive requires enabled `mod_env` module.
