The message ‘apache2: Could not reliably determine the server’s fully qualified domain name, using
- First edit your host file, e.g. /etc/apache2/sites-enabled/000-default and make sure you have you have specified a ServerName. For a local test server you can just use
ServerName localhost.localdomain
For a web server on the internet specify the full domain name
ServerName www.example.org
- Then check your hosts file, /etc/hosts, and make sure it contains the host name that you just specified as ServerName. E.g.
127.0.0.1 localhost.localdomain localhost
or something like
192.0.43.10 www.example.org www
Important: The first value behind the IP address must be the same as ServerName, it won’t work if you turn the host name and fully qualified domain name around. This will not work:
192.0.43.10 www www.example.org
