- Using a text editor, open the server’s /etc/sysconfig/network file.
# sudo nano /etc/sysconfig/network
- Modify the
HOSTNAME= value to match your FQDN hostname.
- For internal networking, change the host that is associated with the main IP address for your server (found at /etc/hosts).
127.0.0.1 localhost localhost.localdomain
184.108.40.206 hostname.domain.com hostname
-- INSERT -- 2,43-57 ALL
- Run the
hostname command. This command lets you change the hostname on the server that the command line remembers, but it does not actively update all programs that are running under the old hostname.
[root@defiant ~]# hostname hostname.domain.com
[root@defiant ~]# hostname
- Restart networking on your server to ensure that changes will persist on restart.
# /etc/init.d/network restart
