Django Apache mod_wsgi settings :)

the lastest Django framework is 1.5.1 while some references are still based on previous distributes.

You could find the newest guideness here: https://docs.djangoproject.com/en/1.5/howto/deployment/wsgi/modwsgi/

But you may need some old references since the lastest one can't cover most.

Here is a reference of django 1.2 https://docs.djangoproject.com/en/1.2/howto/deployment/modwsgi/

They will teach you how to deploy django application on apache and other engines such as nginx, lightd or etc..

 

One thing we should notice:

if you are going to deploy a Django1.5.1 app with apache and mod_wsgi, you will need to edit the following files.

1. wsgi.py

You need to edit the file "  wsgi.py " from the folder of your application.

import os
import sys 

path = '/var/www/jjlmsite'   # 这里为了能让jjlmsite直接被import到，加入到系统路径里面去
if path not in sys.path:
    sys.path.append(path)

# We defer to a DJANGO_SETTINGS_MODULE already in the environment. This breaks
# if running multiple sites in the same mod_wsgi process. To fix this, use
# mod_wsgi daemon mode with each site in its own daemon process, or use
os.environ["DJANGO_SETTINGS_MODULE"] = "jjlmsite.settings"   #这里释放注释
# os.environ.setdefault("DJANGO_SETTINGS_MODULE", "jjlmsite.settings") 这里被注释掉

# This application object is used by any WSGI server configured to use this
# file. This includes Django's development server, if the WSGI_APPLICATION
# setting points here.
from django.core.wsgi import get_wsgi_application  #这里将不做更改
application = get_wsgi_application()

# Apply WSGI middleware here.
# from helloworld.wsgi import HelloWorldApplication
# application = HelloWorldApplication(application)

官方网站上没有上面操作的介绍，所以，在deploy的时候，需要注意一下是否将app的文件夹加入到python的系统路径里面去了。这点比较重要。结合了1.2和1.5的django手册才看到的。

2. httpd.conf

you need to add something like this into httpd.conf

    WSGIScriptAlias /gopalace /var/www/jjlmsite/jjlmsite/wsgi.py
        # url /gopalace will invoke the wsgi.py file
 #   WSGIPythonPath /var/www/jjlmsite
        # WSGIPythonPath is the main folder path of your django project

    <Directory /var/www/jjlmsite/jjlmsite>
        # the folder which has wsgi-functional files
        <Files wsgi.py>
             Order deny,allow
             Allow from all
        </Files>
    </Directory>

上面的WSGIPythonPath /var/www/jjlmsite 是告诉Python 哪个文件夹是有可执行的py文件的。

 

具体效果如下：

响应的是django的app程序返回的结果。

 

 

如果想转换端口访问（非一口多用，一口多用比较混乱，apache效率比较小），让单独的端口直接host一个django的app。则一定需要Using mod_wsgi daemon mode

详情请见：https://docs.djangoproject.com/en/1.5/howto/deployment/wsgi/modwsgi/#using-mod-wsgi-daemon-mode

 

当需要serve静态页面的时候，可以选择nginx等。具体地址如下：
