How to fix Apache – "Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName"

Hi fellas!

Just made a fresh install of Apache2 on my Ubuntu, made some changes and trying to restart it

$ sudo servie apache2 restart

Returned this:

* Restarting web server apache2 apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
... waiting apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName

To fix it you need to edit the httpd.conf file.

$ sudo gedit /etc/apache2/httpd.conf

The file will be blank, no problem, this is default. Add this:

ServerName localhost

And now restart Apache

$ sudo service apache2 restart

Problem solved.

Adios!
