When Appserv is installed, http://localhost or http://127.0.0.1 cannot be opened
When the port is not occupied (I did not install IIS originally), just start ApacheMonitor.exe in the D:AppServApache2.2bin folder.
Start Apache, run it, and that’s it.
When logging in to phpmyadmin, the default account is: root
The password is the password you entered during installation.
If apache fails to run, 80% to 90% of the time the port is occupied. At this time, you need to use Ctrl+Alt+Del to kill certain processes. It's OK to leave the port empty. .
Otherwise, change the port.
