无法启动 apache2,因为它会抛出错误

我对 Ubuntu 了解甚少,当我尝试启动阿帕奇2服务器(如下所示)

root@ns3016274:/etc/apache2/sites-available# sudo service apache2 start
 * Starting web server apache2                                                                                                 (98)Address already in use: AH00072: make_sock: could not bind to address [::]:80
(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
AH00015: Unable to open logs
Action 'start' failed.
The Apache error log may have more information.
 *
 * The apache2 instance did not start within 20 seconds. Please read the log files to discover problems

我确实重新安装了 apache2,但仍然遇到同样的问题。

答案1

答案就在消息中:(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80。当apache2尝试使用bind系统调用开始监听端口 80 时,它失败了,因为其他某个进程已经成功调用了它bind

还有哪个过程?man lsof导致:

sudo lsof -i TCP:80

由于我没有提供 80 端口,因此我们来看一下sshd我的系统上的 22 端口():

$ sudo lsof -i  TCP:22
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
sshd    1686 root    3u  IPv4  13939      0t0  TCP *:ssh (LISTEN)
sshd    1686 root    4u  IPv6  13941      0t0  TCP *:ssh (LISTEN)
