今天我遇到了一个问题

我的 apache 无法重新启动我的 django 应用程序，我不知道为什么。最糟糕的是，它没有任何错误日志，只是空白！

这个问题让我很困惑，需要帮助。

alif@alif-VirtualBox:/var/www/mywebsite/website$ service apache2 restart
* 重启 web 服务器 apache2 [失败]

/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

    ServerAdmin admin@musicplayer.vhost
    ServerName www.musicplayer.vhost
    ServerAlias musicplayer.vhost
    DocumentRoot /var/www/mywebsite


    Alias /static /var/www/mywebsite/website/static
    <Directory /var/www/mywebsite/website/static>
            Require all granted
    </Directory>

    <Directory /var/www/mywebsite/website/website>

            <Files wsgi.py>
            Require all granted
            </Files>

    </Directory>

    WSGIDaemonProcess mywebsite python-path=/var/www/mywebsite:/var/www/mywebsite/env/lib/python2.7/site-packages
    WSGIProcessGroup mywebsite
    WSGIScriptAlias / /var/www/mywebsite/website/website/wsgi.py

    # 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

我的网站上的wsgi.py

import os
from django.core.wsgi import get_wsgi_application
path = '/var/www/mywebsite/website'
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "website.settings")
application = get_wsgi_application()

【解决方案1】：

检查以确保端口 80 上没有监听任何内容。我不确定 website.settings 包含什么，但有可能此 apache 实例正在尝试使用与另一个相同的端口，或者正在运行其他东西端口 80。（这是默认端口）。您可以通过netstat -tulpn | grep :80检查是否有东西在使用该端口

您可以更改此服务器的端口以避免冲突或停止其他进程。
