当我尝试在http://www.satoshi.example.com/mysite访问我的Django网站时，我得到503 Service Temporary Unavailable。
Apache错误日志说
[Tue Feb 28 07:11:09 2012] [error] [client 10.0.0.202] (13)Permission denied: mod_wsgi (pid=4756): Unable to connect to WSGI daemon process 'django' on '/etc/httpd/logs/wsgi.17555.4.1.sock' after multiple attempts.
Apache正确加载mod_wsgi
root@satoshi:~/html/mysite# apachectl -M | grep wsgi
wsgi_module (shared)
Syntax OK
Apache加载/var/www/html/mysite/apache/apache_django_wsgi.conf

<Directory "/var/www/html/mysite/apache">

这是/var/www/html/mysite/apache/django.wsgi
import os
import sys
paths = [ '/var/www/html/mysite',
'/usr/lib/python2.6/site-packages/',
]
for path in paths:
if path not in sys.path:
sys.path.append(path)
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
奇怪的是，我发现自己甚至不需要LoadModule wsgi_module modules/mod_wsgi.so httpd.conf。我认为我的httpd.conf是已加载mod_wsgi的另一个配置的扩展。不确定这是否重要。
到目前为止我提供的内容有什么问题吗？如果您需要更多信息，请与我们联系。提前谢谢！

此问题记录在：
http://code.google.com/p/modwsgi/wiki/ConfigurationIssues#Location_Of_UNIX_Sockets
其他人提供的更改权限的解决方案是错误的。
正确的解决方案是将套接字文件保存到Apache用户可以读取的位置。
在保护日志目录的系统上，他们有时会有一个系统来在你弄乱它们时设置这些权限。因此，任何改变都可能只是暂时的。

我写了这个脚本来处理apache2-mpm-itk上的wsgi socket权限问题
#!/bin/sh
# This script will fix apache wsgi socket permissions
# By default use standard socket location /var/run/apache2/wsgi
#
# You have to add this script after success execute of start|restart|reload
# commands in next files:
# /usr/sbin/apache2ctrl
# /etc/init.d/apache2
WSGISocketPrefix="/var/run/apache2/wsgi"
if [ "$(id -u)" != "0" ]; then
echo "This script must be run as root" 1>&2
exit 1
fi
echo "Wait for other processes to start"
sleep 1
echo "Change wsgi socket permissions"
chmod 0766 ${WSGISocketPrefix}.*

运行apache进程的用户似乎没有从指定位置读/写的权限。
通常通过在VirtualHost conf中设置WSGIDaemonProcess和WSGIProcessGroup指令来解决这个问题。
WSGIDaemonProcess process-name user=user group=group threads=10 python-path=vitrual-env-path
WSGIProcessGroup process-group
您也可以（除非没有任何其他权限/组问题。）只需将相关的路径读/写访问权限添加到运行apache进程的用户。
chmod [apache-user]+rw /etc/httpd/logs/
