[SOLVED] “Could not reliably determine the server’s fully qualified domain name, using … for ServerName”

You might probably faced the same following error while you were restarting the Apache server on Ubuntu.

in either httpd.conf or apache2.conf in /etc/apache2 and restart apache the notice will disappear. 

sudo gedit /etc/apache2/httpd.conf
sudo gedit /etc/apache2/apache2.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 /etc/init.d/apache2 restart
