mod_wsgi (Apache) |
|
================= |
|
|
|
If you are using the `Apache`_ webserver you should consider using `mod_wsgi`_. |
|
|
|
.. _Apache: http://httpd.apache.org/ |
|
|
|
Installing `mod_wsgi` |
|
--------------------- |
|
|
|
If you don't have `mod_wsgi` installed yet you have to either install it using |
|
a package manager or compile it yourself. |
|
|
|
The mod_wsgi `installation instructions`_ cover source installations on UNIX |
|
systems. |
|
|
|
If you are using ubuntu / debian you can apt-get it and activate it as follows:: |
|
|
|
# apt-get install libapache2-mod-wsgi |
|
|
|
On FreeBSD install `mod_wsgi` by compiling the `www/mod_wsgi` port or by using |
|
pkg_add:: |
|
|
|
# pkg_add -r mod_wsgi |
|
|
|
If you are using pkgsrc you can install `mod_wsgi` by compiling the |
|
`www/ap2-wsgi` package. |
|
|
|
If you encounter segfaulting child processes after the first apache reload you |
|
can safely ignore them. Just restart the server. |
|
|
|
Creating a `.wsgi` file |
|
----------------------- |
|
|
|
To run your application you need a `yourapplication.wsgi` file. This file |
|
contains the code `mod_wsgi` is executing on startup to get the application |
|
object. The object called `application` in that file is then used as |
|
application. |
|
|
|
For most applications the following file should be sufficient:: |
|
|
|
from yourapplication import app as application |
|
|
|
If you don't have a factory function for application creation but a singleton |
|
instance you can directly import that one as `application`. |
|
|
|
Store that file somewhere that you will find it again (e.g.: |
|
`/var/www/yourapplication`) and make sure that `yourapplication` and all |
|
the libraries that are in use are on the python load path. If you don't |
|
want to install it system wide consider using a `virtual python`_ instance. |
|
|
|
Configuring Apache |
|
------------------ |
|
|
|
The last thing you have to do is to create an Apache configuration file for |
|
your application. In this example we are telling `mod_wsgi` to execute the |
|
application under a different user for security reasons: |
|
|
|
.. sourcecode:: apache |
|
|
|
<VirtualHost *> |
|
ServerName example.com |
|
|
|
WSGIDaemonProcess yourapplication user=user1 group=group1 threads=5 |
|
WSGIScriptAlias / /var/www/yourapplication/yourapplication.wsgi |
|
|
|
<Directory /var/www/yourapplication> |
|
WSGIProcessGroup yourapplication |
|
WSGIApplicationGroup %{GLOBAL} |
|
Order deny,allow |
|
Allow from all |
|
</Directory> |
|
</VirtualHost> |
|
|
