Apache2 mod_wsgi，500 内部服务器错误

Question

我用 Apache2 设置了 django App，

1) 虚拟主机：

<VirtualHost *:80>
    ServerAdmin webadmin@publisy.com
    ServerName alpha101.publisy.com
    DocumentRoot /var/www/mysite

    WSGIScriptAlias / /usr/local/django/mysite/apache/django.wsgi
    Alias /static/ /var/www/mysite/media/static/
    <Directory /var/www/mysite/media/static>
        Order deny,allow
        Allow from all
    </Directory>

    Alias /media/ /var/www/mysite/media/
    <Directory /var/www/mysite/media>
        Order deny,allow
        Allow from all
    </Directory>

    ErrorLog /var/log/apache2/error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    CustomLog /var/log/apache2/access.log combined

</VirtualHost>

2) wsgi 脚本（位于 /usr/local/django/mysite/apache/django.wsgi）

import os, sys
sys.path.append('/usr/local/django')
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'

import django.core.handlers.wsgi

application = django.core.handlers.wsgi.WSGIHandler()

谁能指出哪里出了问题？

Answer 1

好像有点小问题。看起来您的“站点”目录是 /var/www/mysite。

将此添加到 django.wsgi 中的 python 路径。

sys.path.append('/var/www')
sys.path.append('/var/www/mysite')

事实上你发布的错误

TemplateSyntaxError: Caught an exception while rendering: No module named destinations 

似乎 wsgi 找不到模块目的地。将目录路径添加到 django.wsgi 中的 python 路径，它应该可以工作。

Answer 2

如果你有DEBUG=False 或者你的IP 地址不在INTERNAL_IPS 中，任何django 错误都会给你错误500，甚至像KeyError 这样的东西。通常，生产服务器在环境中存在差异，因此，即使在本地主机上一切正常，您也可能会在生产中发现一些问题。

两种查看问题的方法：

1. 只需将您的 ip 添加到 INTERNAL_IPS（获取您当前的 ip 地址）或将 DEBUG 设置为 true
2. 查看 apache error.log 或您在 settings.py 中设置的电子邮件（错误默认通过电子邮件发送）

另外，请记住，您必须在进行更改后重新启动服务器。

祝你好运！
