我已经安装了Centos 7的新副本.然后我重新启动了Apache，但是Apache无法启动.我在此问题上停留了3天.甚至支持人员也无法找出错误.

来自您的输出:
没有可用的监听套接字，正在关闭
no listening sockets available, shutting down
从根本上讲，一个Apache将要监听的端口已被另一应用程序使用.
what basically means, that any port in which one apache is going to be listening is already being used by another application.
netstat -punta | grep LISTEN
将为您提供所有正在使用的端口的列表以及识别哪个进程所需的信息，以便您可以kill stop或使用它进行任何操作.
Will give you a list of all the ports being used and the information needed to recognize which process is so you can kill stop or do whatever you want to do with it.
对您的IP做nmap后，我可以看到
After doing a nmap of your ip I can see that
80/tcp open http
所以我想你已经解决了.
so I guess you sorted it out.
