After the initial install of Apache in Ubuntu, you’ll first see this message below:

stmiller@brahms:~$ sudo /etc/init.d/apache2 restart
* 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

If you are not planning on using virtualhosts or other configurations, you can simply create a file specifying the ServerName as below.

1. Create this apache config file:

sudo nano /etc/apache2/conf.d/fqdn

2. Add this to the file:

ServerName localhost

Or make it your desired host or domain name such as:

ServerName example.com

3. Save (in nano: Control + X, then Yes to confirm) and restart Apache:

sudo /etc/init.d/apache2 restart

Done!
