This error is usually harmless. Sometimes you don’t require a complex /etc/hosts file that includes all your virtual hosts.
220.127.116.11 localhost.localdomain localhost 127.0.1.1 blogs
service apache2 restart
You might get this error:
AH00557: apache2: apr_sockaddr_info_get() failed for blogs AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1. Set the 'ServerName' directive globally to suppress this message
A quick solution to this problem:
vim /etc/apache2/apache2.conf # Insert at the end of the file ServerName localhost service apache2 restart * Restarting web server apache2 [ OK ]
