Everytime I start apache2 (# apache2ctl start) this message is dispalyed:

apache2: Could not reliably determine the server’s fully qualified domain name, using for ServerName

Well, the site is still running despite the above notification.

To fix it, we need to edit the /etc/apache2/httpd.conf or /etc/apache2.conf and add the following line:

ServerName nameofserver

Now, restart the apache server (# apache2ctrl restart) and should no loger see the previous message.
