Resolve serverName error when apache is started

The error "Please use 127.0.0.1 as servername" is reported when apache is installed and started in linux.
The solution is actually very simple. Find httpd In the conf directory. conf, open it, and find the # ServerName 127.0.0.1: 80 line. Just remove the comment and change the ip address to your domain name. If there is no domain name, change it to the local ip address.
Try it after startup. If an error is reported, check whether the startup command is entered with the Shell code. /apachectl start if you are using apachectl start, it will be wrong, because it is possible that apache is included in the local installation, and you modify the newly installed apache.
