Apache Reload Error

* Reloading web server config apache2                                                                                                           apache2:Couldnot reliably determine the server’s fully qualified domain name, using for ServerName

I solved it by:

To fix that problem, you need to edit the httpd.conf file. Open the terminal and type,

$ sudo gedit /etc/apache2/httpd.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
