项目的要求是当有人使用端口80访问应用程序时，他们应该看到默认应用程序，但是如果有人使用端口8083访问应用程序，那么他们应该看到应用程序的控制面板。
我在CentOS上，在Listen 80崩溃Apache中添加Listen 8083和httpd.conf。
cpanel.conf
<VirtualHost *:8083>
ServerName cpanel.com
ServerAlias www.cpanel.com
DocumentRoot /var/www/cpanel
</VirtualHost>
当我重新启动Apache时，我收到以下错误消息。

我是新手，所以你的帮助将受到高度赞赏。
您可以首先验证在启动Apache之前没有任何内容已经在侦听端口8083，例如：
netstat -an|grep LISTEN|grep 8083
另外，你是否在root下启动Apache？如果你想让它听到端口80，你需要它。什么在困扰我，它是日志条目，声明它无法打开日志。除了添加Listen 8083之外，您还有其他更改吗？
