8 | | CGI script is the entrypoint that web-server calls when a web-request to an application is made. 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. |

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 an URL 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. |

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. It is also possible to set TRAC_ENV in trac.cgi. Just add the following code between "try:" and "from trac.web ...":'' |
| 39 | ''Note that the `SetEnv` directive requires that the `mod_env` module is enabled.'' |
43 | 40 | |
44 | | {{{ |
45 | | import os |
| 41 | An alternative to `SetEnv` is editing `TRAC_ENV` or `TRAC_ENV_PARENT_DIR` in `trac.cgi`: |
| 42 | |
| 43 | {{{#!python |
46 | 44 | os.environ['TRAC_ENV'] = "/path/to/projectenv" |
47 | 45 | }}} |
48 | 46 | |
49 | | '' Or for TRAC_ENV_PARENT_DIR: '' |
50 | | |
51 | | {{{ |
52 | | import os |
53 | | os.environ['TRAC_ENV_PARENT_DIR'] = "/path/to/project/parent/dir" |
| 47 | {{{#!python |
| 48 | os.environ['TRAC_ENV_PARENT_DIR'] = "/path/to/parent/dir" |

58 | | 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). |

60 | | === Using WSGI === |
| 55 | === Python Egg Cache |
| 56 | |
| 57 | The [TracInstall#egg-cache egg-cache] can be configured using an `os.environ` statement in `trac.cgi`, as shown above. |
| 58 | To do the same from the Apache configuration, use the `SetEnv` directive: |
| 59 | {{{#!apache |
| 60 | SetEnv PYTHON_EGG_CACHE /path/to/dir |
| 61 | }}} |
| 62 | |
| 63 | Put this directive next to where you set the path to the [TracEnvironment Trac environment], i.e. in the same `<Location>` block. |
| 64 | |
| 65 | {{{#!apache |
| 66 | <Location /trac> |
| 67 | SetEnv TRAC_ENV /path/to/projenv |
| 68 | SetEnv PYTHON_EGG_CACHE /path/to/dir |
| 69 | </Location> |
| 70 | }}} |
| 71 | |
| 72 | |
| 73 | |
| 74 | === Using WSGI |
61 | 75 | |
62 | 76 | 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. |
