It will warn you that
AH00558: httpd: Could not reliably determine the server‘s fully qualified domain name, using 127.0.1.1. Set the ‘ServerName‘ directive globally to suppress this message
This is a friendly warning and not an error. You can launch a browser and visit http://127.0.1.1 and a simple webpage saying "It works!" appears. The default document root is /usr/local/apache2/htdocs/ where we can put an hello_world.html and this html file‘s address is http://127.0.1.1/hello_world.html
If you want to turn off the server, run command
/usr/local/apache2/bin/apachectl stop
The same warning appears
