+ | ====== Trac and mod_python ====== | ||
+ | [[: | ||
+ | |||
+ | Trac supports [[http:// | ||
+ | |||
+ | ===== Simple configuration ===== | ||
+ | |||
+ | If you just installed mod_python, you may have to add a line to load the module in the Apache configuration: | ||
+ | < | ||
+ | LoadModule python_module modules/ | ||
+ | </ | ||
+ | |||
+ | |||
+ | // | ||
+ | |||
+ | You can test your mod_python installation by adding the following to your httpd.conf. | ||
+ | < | ||
+ | < | ||
+ | | ||
+ | | ||
+ | </ | ||
+ | </ | ||
+ | |||
+ | |||
+ | A simple setup of Trac on mod_python looks like this: | ||
+ | < | ||
+ | < | ||
+ | | ||
+ | | ||
+ | | ||
+ | | ||
+ | </ | ||
+ | </ | ||
+ | |||
+ | |||
+ | The option **`TracUriRoot`** may or may not be necessary in your setup. Try your configuration with out it, and if the URLs produced by Trac look wrong or if Trac does not seem to recognize the URLs correctly, add the **`TracUriRoot`** option. | ||
+ | |||
+ | ==== Configuring Authentication ==== | ||
+ | |||
+ | Configuring authentication works just like for [[: | ||
+ | < | ||
+ | < | ||
+ | AuthType Basic | ||
+ | AuthName " | ||
+ | AuthUserFile / | ||
+ | Require valid-user | ||
+ | </ | ||
+ | </ | ||
+ | |||
+ | |||
+ | ==== Setting the PythonPath ==== | ||
+ | |||
+ | If the Trac installation isn't installed in your Python path, you'll have to tell Apache where to find the Trac mod_python handler | ||
+ | < | ||
+ | < | ||
+ | ... | ||
+ | PythonPath " | ||
+ | ... | ||
+ | </ | ||
+ | </ | ||
+ | |||
+ | |||
+ | Be careful about using the PythonPath directive, and //not// `SetEnv PYTHONPATH`, | ||
+ | |||
+ | ===== Setting up multiple projects ===== | ||
+ | |||
+ | The Trac mod_python handler supports a configuration option similar to Subversion' | ||
+ | < | ||
+ | < | ||
+ | SetHandler mod_python | ||
+ | PythonHandler trac.web.modpython_frontend | ||
+ | PythonOption TracEnvParentDir /var/trac | ||
+ | PythonOption TracUriRoot /projects | ||
+ | </ | ||
+ | </ | ||
+ | |||
+ | |||
+ | When you request the `/projects` URL, you will get a listing of all subdirectories of the directory you set as `TracEnvParentDir` that look like Trac environment directories. Selecting any project in the list will bring you to the corresponding Trac environment. | ||
+ | |||
+ | If you don't want to have the subdirectory listing as your projects home page you can use a | ||
+ | < | ||
+ | < | ||
+ | </ | ||
+ | |||
+ | |||
+ | This will instruct Apache to use mod_python for all locations different from root while having the possibility of placing a custom home page for root in your DocumentRoot folder. | ||
+ | |||
+ | You can also use the same authentication realm for all of the projects using a `< | ||
+ | < | ||
+ | < | ||
+ | AuthType Basic | ||
+ | AuthName " | ||
+ | AuthUserFile / | ||
+ | Require valid-user | ||
+ | </ | ||
+ | </ | ||
+ | |||
+ | |||
+ | ===== Virtual Host Configuration ===== | ||
+ | |||
+ | Below is the sample configuration required to set up your trac as a virtual server (i.e. when you access it at the URLs like | ||
+ | http:// | ||
+ | |||
+ | < | ||
+ | < | ||
+ | DocumentRoot / | ||
+ | ServerName trac.mycompany.com | ||
+ | < | ||
+ | SetHandler mod_python | ||
+ | PythonHandler trac.web.modpython_frontend | ||
+ | PythonOption TracEnv / | ||
+ | PythonOption TracUriRoot / | ||
+ | </ | ||
+ | < | ||
+ | AuthType Basic | ||
+ | AuthName " | ||
+ | AuthUserFile / | ||
+ | Require valid-user | ||
+ | </ | ||
+ | </ | ||
+ | </ | ||
+ | |||
+ | |||
+ | For a virtual host that supports multiple projects replace " | ||
+ | |||
+ | ===== Troubleshooting ===== | ||
+ | |||
+ | In general, if you get server error pages, you can either check the Apache error log, or enable the `PythonDebug` option: | ||
+ | < | ||
+ | < | ||
+ | ... | ||
+ | PythonDebug on | ||
+ | </ | ||
+ | </ | ||
+ | |||
+ | |||
+ | ==== Form submission problems ==== | ||
+ | |||
+ | If you're experiencing problems submitting some of the forms in Trac (a common problem is that you get redirected to the start page after submission), | ||
+ | |||
+ | ==== Problem with virtual host configuration ==== | ||
+ | |||
+ | If the < | ||
+ | |||
+ | Using < | ||
+ | |||
+ | ==== Using .htaccess ==== | ||
+ | |||
+ | Although it may seem trivial to rewrite the above configuration as a directory in your document root with a `.htaccess` file, this does not work. Apache will append a "/" | ||
+ | |||
+ | It may be possible to work around this with mod_rewrite, | ||
+ | |||
+ | ==== Win32 Issues ==== | ||
+ | If you run trac with mod_python < 3.2 on Windows, uploading attachments will **not** work. This problem is resolved in mod_python 3.1.4 or later, so please upgrade mod_python to fix this. | ||
+ | |||
+ | ==== OS X issues ==== | ||
+ | |||
+ | When using mod_python on OS X you will not be able to restart Apache using `apachectl restart`. This is apparently fixed in mod_python 3.2, but there' | ||
+ | |||
+ | ==== SELinux issues ==== | ||
+ | |||
+ | If Trac reports something like: //Cannot get shared lock on db.lock// | ||
+ | The security context on the repository may need to be set: | ||
+ | |||
+ | < | ||
+ | chcon -R -h -t httpd_sys_content_t PATH_TO_REPOSITORY | ||
+ | </ | ||
+ | |||
+ | |||
+ | See also [[[http:// | ||
+ | |||
+ | ==== FreeBSD issues ==== | ||
+ | Pay attention to the version of the installed mod_python and sqlite packages. Ports have both the new and old ones, but earlier versions of pysqlite and mod_python won't integrate as the former requires threaded support in python, and the latter requires a threadless install. | ||
+ | |||
+ | ==== Subversion issues ==== | ||
+ | |||
+ | If you get the following Trac Error `Unsupported version control system " | ||
+ | |||
+ | If this is not the case, it's possible that you're using Subversion libraries that are binary incompatible with the apache ones (an incompatibility of the `apr` libraries is usually the cause). In that case, you also won't be able to use the svn modules for Apache (`mod_dav_svn`). | ||
