【问题描述】：

我能够通过 Apache 服务器运行一个 django 项目。 我有两个项目：yota_admin_module 和 yotasite。 我的 Apache 配置文件：/etc/apache2/sites-available/000-default.conf

<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com

Alias /static /home/abhay/django-project/yota_admin_module/yota/static/
WSGIDaemonProcess yota_admin_module python-path=/home/abhay/django-project/yota_admin_module:/usr/local/lib/python2.7/site-packages
WSGIProcessGroup yota_admin_module
WSGIScriptAlias / /home/abhay/django-project/yota_admin_module/yota_admin_module/wsgi.py

<Directory /home/abhay/django-project/yota_admin_module/ >
       Require all granted
</Directory>

# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn

ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined

# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf

但是现在我在尝试使用该 Apache 服务器运行另一个 django 项目时遇到了问题。 所以，我做了什么：在 /etc/apache2/sites-available/000-default.conf 这样修改：

<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com

Alias /static /home/abhay/django-project/yota_admin_module/yota/static/
WSGIDaemonProcess yota_admin_module python-path=/home/abhay/django-project/yota_admin_module:/usr/local/lib/python2.7/site-packages
WSGIProcessGroup yota_admin_module
WSGIScriptAlias / /home/abhay/django-project/yota_admin_module/yota_admin_module/wsgi.py

<Directory /home/abhay/django-project/yota_admin_module/ >
       Require all granted
</Directory>

WSGIDaemonProcess yotasite python-path=/home/abhay/django-project/yotasite:/usr/local/lib/python2.7/site-packages
WSGIProcessGroup yotasite
WSGIScriptAlias / /home/abhay/django-project/yotasite/yotasite/wsgi.py

<Directory /home/abhay/django-project/yotasite/ >
       Require all granted
</Directory>


# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.

# following line enables the CGI configuration for this host only

#Include conf-available/serve-cgi-bin.conf

所以，修改后当“sudo service apache2 restart”出现错误时：

所以，我需要一些指导来解决这个问题，以便使用 Apache 服务器运行两个 django 项目。

    各种错误。请参阅下面的 cmets。

    # Best to match trailing slashes on both arguments to be safe. If

    【讨论】：

    • -> 感谢您的指导。还有一件事请您解释一下： # 您不能将两个站点都安装在主机的根目录下。这第二个 #one 将始终被第一个隐藏，并且永远不会收到任何请求。 # 如果希望两者都使用相同的服务器名称，则需要在子 URL 中设置 # 一个。子 URL 必须是第一个。那是在＃之前，用于站点的根目录。以及如何实施。我希望两个站点都通过 Apache 运行。
    • 您必须将它们作为不同的主机名，这意味着您必须拥有多个 VirtualHost，每个虚拟主机一个。然后，您需要在您的控制下单独的主机名，这些主机名可用于映射到它们。否则，您使用不同的端口，使用不同的 VirtualHost，或者将一个放在子 URL 下。您不能让两者都尝试在站点根目录接受相同主机名的请求。
