apache 启动失败，没有错误日志

Question

今天我遇到了一个问题

我的 Apache 未能重新启动我的 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，只是一片空白！

这个问题让我很困惑，需要帮助。

alif@alif-VirtualBox:/var/www/mywebsite/website$ service apache2 restart
* Restarting web server apache2 [fail]

/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

    # 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

wsgi.py 在我的网站上

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()

检查以确保没有任何东西在端口 80 上侦听。我不确定 website.settings 包含什么，但有可能是这个 apache 实例正在尝试使用与另一个相同的端口，或者其他什么else 是端口 80 上的运行。（这是默认端口）。您可以通过 netstat -tulpn | grep :80

检查是否有东西正在使用该端口

您可以更改此服务器的端口以避免冲突，或者停止其他进程。
