Apache is one of commonly used web servers in Linux. At the time modifying apache, you need to restart it for updating the modifications without restarting Linux. Sometimes, we may face with the following troubleshooting:

Apache2 with the error the fully qualified domain name
“The fully qualified domain name” error

To fix that problem, you need to edit the httpd.conf file. Open the terminal and type,

sudo gedit /etc/apache2/httpd.conf

By default httpd.conf file will be blank. Now, simply add the following line to the file.

ServerName localhost

Save the file and exit from gedit. Finally restart the server.

sudo service apache2 restart

Or use the instructions:

sudo /etc/init.d/apache2 restart
