Howto configure Apache WSGI for multiple separate

问题:

I have an apache instance where I have the following

WSGIPythonPath /production/somelocation/django12/lib/python2.4/site-packages/
<VirtualHost 192.168.1.1:443>
        WSGIScriptAlias / /opt/project.wsgi
        .....

My Django 1.5 app apache config looks like,

WSGIPythonPath /production/somelocation/django15/lib/python2.7/site-packages/
<VirtualHost 192.168.1.2:443>
        ....
        WSGIScriptAlias / /opt/project2.wsgi

My /opt/project.wsgi looks like

import os
import sys

# django1.2 virtualenv
import site
site.addsitedir("/production/somelocation/django12/lib/python2.4/site-packages")
.....

However when I go to the site I still get my default django (1.5) instance. What am I missing ?

回答1:

The other answers mention setting the python path, however using WSGIPythonPath or WSGIPythonHome are not correct. The WSGIPythonPath / WSGIPythonHome can only be set server-wide, so no different paths per virtualhost.

You would want to use the WSGIDaemonProcess python-path and home arguments to set the python path and your apps home directory per virtualhost.

Also, within your code there is no need to adjust python paths; just make sure your virtualhost config is correct.

回答2:

You may need to set WSGIPythonHome since you have different Django installations.

WSGIPythonPath is used to define additional directories, but this option do not set default python installation. So probably, your default python directory also includes django (1.5) and recognize this version as the default django version. I do not know your python and django installation and configuration but this might be the reason.

This is how I do with Pyramid:

<VirtualHost *:80>
    Servername hackintosh
    DocumentRoot "/Library/WebServer/Documents"
</VirtualHost>


<VirtualHost *:80>
    ServerName modwebsocket.local
    ErrorLog "/PythonProjects/MOD_WEBSOCKET/logs/error_log"
    CustomLog "/PythonProjects/MOD_WEBSOCKET/logs/access_log" common

    WSGIDaemonProcess pyramid-modwebsocket user=apero group=staff threads=4 python-path=/PythonProjects/MOD_WEBSOCKET/lib/python2.7/site-packages
    WSGIProcessGroup pyramid-modwebsocket

    WSGIScriptAlias /  /PythonProjects/MOD_WEBSOCKET/wsgi/pyramid.wsgi

    <Directory "/PythonProjects/MOD_WEBSOCKET/wsgi">
        WSGIProcessGroup pyramid-modwebsocket
        Order allow,deny
        Allow from all
    </Directory>

</VirtualHost>

<VirtualHost *:80>
    ServerName ai.local
    ErrorLog "/PythonProjects/AI/logs/error_log"
    CustomLog "/PythonProjects/AI/logs/access_log" common

    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    WSGIDaemonProcess pyramid-ai user=apero group=staff threads=4 python-path=/PythonProjects/AI/lib/python2.7/site-packages
    WSGIProcessGroup pyramid-wizard

    WSGIScriptAlias /  /PythonProjects/AI/wsgi/pyramid.wsgi

    <Directory "/PythonProjects/AI/wsgi">
        WSGIProcessGroup pyramid-ai
        Order allow,deny
        Allow from all
    </Directory>

</VirtualHost>
