Hostname

Adjust /etc/hosts

Next we edit /etc/hosts. Make it look like this:

mcedit /etc/hosts

127.0.0.1               localhost.localdomain localhost
192.168.0.100           server1.example.com server1

Setting The Hostname

(This step is optional.)

This is not necessary if you have set the correct hostname during the installation. You can check the current hostname with the commands

hostname
hostname -f

Both commands should show server1.example.com.

If the output shows a wrong hostname, you can set the correct one like this:

echo server1.example.com > /etc/hostname
/bin/hostname -F /etc/hostname
