r40226 r40551 1 = Installing Trac as CGI2 [[TracGuideToc]]3 [[PageOutline]]4 5 {{{#!div class=important6 ''Please note that using Trac via CGI is the slowest deployment method available. It is slower than [TracModPython mod_python], [TracFastCgi FastCGI] and even [trac:TracOnWindowsIisAjp IIS/AJP] on Windows.''7 }}}8 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.10 11 == Apache web-server configuration12 13 In [http://httpd.apache.org/ Apache] there are two ways to run Trac as CGI:14 15 1. Use a `ScriptAlias` directive that maps an URL to the `trac.cgi` script (recommended)16 1. 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.17 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:19 {{{#!apache20 ScriptAlias /trac /path/to/www/trac/cgi-bin/trac.cgi21 }}}22 23 ''Note that this directive requires enabled `mod_alias` module.''24 25 If you're using Trac with a single project you need to set its location using the `TRAC_ENV` environment variable:26 {{{#!apache27 <Location "/trac">28 SetEnv TRAC_ENV "/path/to/projectenv"29 </Location>30 }}}31 32 Or to use multiple projects you can specify their common parent directory using the `TRAC_ENV_PARENT_DIR` variable:33 {{{#!apache34 <Location "/trac">35 SetEnv TRAC_ENV_PARENT_DIR "/path/to/project/parent/dir"36 </Location>37 }}}38 39 ''Note that the `SetEnv` directive requires enabled `mod_env` module. It is also possible to set TRAC_ENV in trac.cgi. Just add the following code between "try:" and "from trac.web ...":''40 41 {{{#!python42 import os43 os.environ['TRAC_ENV'] = "/path/to/projectenv"44 }}}45 46 '' Or for TRAC_ENV_PARENT_DIR: ''47 48 {{{#!python49 import os50 os.environ['TRAC_ENV_PARENT_DIR'] = "/path/to/project/parent/dir"51 }}}52 53 If you are using the [http://httpd.apache.org/docs/suexec.html Apache suEXEC] feature please see [trac:ApacheSuexec].54 55 On some systems, you ''may'' need to edit the shebang line in the `trac.cgi` file to point to your real Python installation path. On a Windows system you may need to configure Windows to know how to execute a .cgi file (Explorer -> Tools -> Folder Options -> File Types -> CGI).56 57 === Using WSGI58 59 You can run a [http://henry.precheur.org/python/how_to_serve_cgi WSGI handler] [http://pythonweb.org/projects/webmodules/doc/0.5.3/html_multipage/lib/example-webserver-web-wsgi-simple-cgi.html under CGI]. You can [wiki:TracModWSGI#Thetrac.wsgiscript write your own application function], or use the deployed trac.wsgi's application.60 61 == Mapping Static Resources62 63 See TracInstall#MappingStaticResources.64 65 == Adding Authentication66 67 See TracInstall#ConfiguringAuthentication.68 69 ----70 See also: TracGuide, TracInstall, [wiki:TracModWSGI], TracFastCgi, TracModPython
