在 Apache 上将多个 WSGI 应用程序作为不同的虚拟主机提供服务

Question

我有一个 EC2 AWS 服务器，我想在其上托管几个 Django 应用程序。这些应用程序中的每一个都有自己的 URL。例如，

example1.com example2.com

就其本身而言，example1.com 有效。问题是让example2.com 同时使用它。

当我访问example2.com时，我得到一个错误：

DisallowedHost at /
Invalid HTTP_HOST header: 'example2.com'. You may need to add 'example2.com' to ALLOWED_HOSTS.
Request Method: GET
Request URL:    http://example2.com
Django Version: 1.9.13
Exception Type: DisallowedHost
Exception Value:

如您所见，Apache 在为example2.com 服务时试图以某种方式使用example1.com 的虚拟环境。我该如何纠正？每个都应该使用自己的 virtualenv。

这里是 Apache 配置文件：

    <VirtualHost *:80>
        # This is name based virtual hosting. So place an appropriate server name
        #   here. Example: django.devsrv.local
        ServerName  example1.com

        WSGIDaemonProcess example1 python-home=/var/www/vhosts/example1/example1-env
        WSGIProcessGroup %{GLOBAL}

        # Insert the full path to the wsgi.py-file here
        WSGIScriptAlias / /var/www/vhosts/example1/example1/wsgi.py

        <Directory /var/www/vhosts/example1/>
            Require all granted
        </Directory>

        Alias /static/ /var/www/vhosts/example1/static/

        <Directory /var/www/vhosts/example1/static/>
        Order deny,allow
        Allow from all
        </Directory>

        Alias /media/ /var/www/vhosts/example1/media/
        <Directory /var/www/vhosts/example1/media/>
        Order deny,allow
        Allow from all
        </Directory>

    </VirtualHost>

    <VirtualHost *:80>
        # This is name based virtual hosting. So place an appropriate server name
        #   here. Example: django.devsrv.local
        ServerName  example2.com
        WSGIDaemonProcess example2 python-home=/var/www/vhosts/example2/example2-env
        WSGIProcessGroup %{GLOBAL}

        # Insert the full path to the wsgi.py-file here
        WSGIScriptAlias / /var/www/vhosts/example2/example2/wsgi.py

        <Directory /var/www/vhosts/example2/>
            Require all granted
        </Directory>

        Alias /static/ /var/www/vhosts/example2/static/

        <Directory /var/www/vhosts/example2/static/>
        Order deny,allow
        Allow from all
        </Directory>

        Alias /media/ /var/www/vhosts/example2/media/
        <Directory /var/www/vhosts/example2/media/>
        Order deny,allow
        Allow from all
        </Directory>
  </VirtualHost>

编辑： 在阅读了 cmets 中的一些建议后，我来到了这里。这仍然不起作用。

ServerName  example1.com

WSGIDaemonProcess example1 display-name=%{GROUP} python-path=/var/www/vhosts/example1/ python-home=/var/www/vhosts/example1/example1-env/
WSGIApplicationGroup %{GLOBAL}
WSGIProcessGroup example1

# Insert the full path to the wsgi.py-file here
WSGIScriptAlias / /var/www/vhosts/example1/example1/wsgi.py process-group=example1

...

ServerName  example2.com

WSGIDaemonProcess example2 display-name=%{GROUP} python-home=/var/www/vhosts/example2/example2-env/ python-path=/var/www/vhosts/example2/
WSGIApplicationGroup %{GLOBAL}
WSGIProcessGroup example2

# Insert the full path to the wsgi.py-file here
WSGIScriptAlias / /var/www/vhosts/example2/example2/wsgi.py process-group=example2

以下配置对我有用。简而言之，它使用各自的虚拟环境在example1.com 和example2.com 为两个不同的 Django 应用程序提供服务。

如您所见，插入 ServerAlias AND ServerName 带来了巨大的变化，同时社区提出了一些其他更正建议。

Apache 配置：

<IfModule !wsgi_module>
LoadModule wsgi_module modules/mod_wsgi.so
</IfModule>

<VirtualHost *:80>

    ServerName  www.example1.com
    ServerAlias example1.com

    WSGIDaemonProcess example1 display-name=%{GROUP} python-path=/var/www/vhosts/example1/ python-home=/var/www/vhosts/example1/example1-env/
    WSGIApplicationGroup %{GLOBAL}
    WSGIProcessGroup example1


    # Insert the full path to the wsgi.py-file here
    WSGIScriptAlias / /var/www/vhosts/example1/example1/wsgi.py process-group=example1

    <Directory /var/www/vhosts/example1/>
        Require all granted
    </Directory>

    Alias /static/ /var/www/vhosts/example1/static/

    <Directory /var/www/vhosts/example1/static/>
    Order deny,allow
    Allow from all
    </Directory>

    Alias /media/ /var/www/vhosts/example1/media/
    <Directory /var/www/vhosts/example1/media/>
    Order deny,allow
    Allow from all
    </Directory>
</VirtualHost>

<VirtualHost *:80>

    ServerName  www.example2.com
    ServerAlias example2.com

    WSGIDaemonProcess example2 display-name=%{GROUP} python-home=/var/www/vhosts/example2/example2-env/ python-path=/var/www/vhosts/example2/
    WSGIApplicationGroup %{GLOBAL}
    WSGIProcessGroup example2

    # Insert the full path to the wsgi.py-file here
    WSGIScriptAlias / /var/www/vhosts/example2/example2/wsgi.py process-group=example2

    <Directory /var/www/vhosts/example2/>
        Require all granted
    </Directory>

    Alias /static/ /var/www/vhosts/example2/static/

    <Directory /var/www/vhosts/example2/static/>
    Order deny,allow
    Allow from all
    </Directory>

    Alias /media/ /var/www/vhosts/example2/media/
    <Directory /var/www/vhosts/example2/media/>

</VirtualHost>
