apache2: Could not reliably determine the server’s fully qualified domain name, using x.x.x.x for ServerName

error ini muncul di ubuntu server edition, solusinya adalah sangat mudah ternyata:

edit: /etc/apache2/apache2.conf

insert baris ini:

ServerName x.x.x.x (ip address nameserver jaringan anda)

setelah itu coba restart apache (apache2ctl restart)

selesai deh :)
