OpenSUSE – Change hostname

After installing of an OpenSUSE server the hostname often has to be modified. The following steps must be performed via the CLI:

1. Open the /etc/hostname file with a text editor (vi/nano) and change the hostname:
   sudo vi /etc/hostname
   
   
2. Next open the /etc/hosts file and change the hostname:
   sudo vi /etc/hosts
   
   
3. To apply the changes, the server has to be rebooted:
   sudo reboot
