Fix Apache FDQ Error
If you’re working on Ubuntu and running Apache, you probably have seen this error when rebooting Apache. It says “could not reliably determine the server’s fully qualified domain name.” There’s a simple fix to this configuration issue.
You’ll need to edit the /etc/apache2/httpd.conf config file:
<pre lang="html">sudo nano /etc/apache2/httpd.conf
and add this entry:
<pre lang="html">ServerName localhost
Reboot Apache
<pre lang="html">sudo /etc/init.d/apache2 restart
The error is now gone.
