Apache cannot be started: Windows cannot start apache2.2, error 1067.

When I started Apache today, I got an error: Windows cannot start the apache2.2 service (on a local computer). Error 1067: the process was unexpectedly terminated.

My first response was to turn off the IIS server and start it again. The same error was reported. So I checked the Windows System Log and found the exception: httpd.exe: cocould not reliably determine the server's fully qualified domain name, using 192.168.1.11 for servername. Ping your own IP address 192.168.1.11, view the Apache configuration file, and fill in 192.168.1.100. I changed my ADSL service this morning. As a result, my original IP address 192.168.1.100 was changed to 192.168.1.11 because it was automatically obtained. So I changed it back to 192.168.1.11 in the configuration file and started successfully.

I am not depressed about this problem, but when I searched for a solution on the Internet, many people on the internet answered: reinstall Apache, reinstall MySQL, or even say that the system was poisoned or reinstalled. In the end, even if you happen to solve the problem, you still know it, but you don't know why.
