Action 'configtest' failed.

Please tell me how i restart my apache2 server...

Answer 1

Apparently, you have a syntax error in a config file. The first step would be to look at /etc/apache2/conf.d/fqdn to see what it says, and perhaps post the contents of the file if you need help. You can check this file with a text editor, or use cat or less (ie gedit /etc/apache2/conf.d/fqdn).

FYI, this file stands for "Fully Qualified Domain Name", and is normally a single line with something like this:

ServerName localhost

That should be all that is necessary for a home server. Did you change this file?
