ubuntu21.10无法执行apache2重启命令

Question

After I executed the command: sudo systemctl restart apache2 in the terminal, it prompted an error:

Job for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xeu apache2.service" for details.

After executing the systemctl status apache2.service command according to the above prompt, I received this prompt:

Answer 1

Its possible that you may already have some other webserver running on your website which is using port 80, because you have error RTT apachectl[14923]: (98)Address already in use: AH00072: make>

Please try this:

Check first what is using port 80

sudo netstat -nap | grep 80

Now use command to identify process (in my case "httpd")

ps -ax | grep httpd

If you identify the process please kill them and try again to restart apache2.
