edit the file /etc/sysconfig/network

append the desired hostname after HOSTNAME=
save your changes and reboot.

If you don't wish to reboot, then execute this command:
echo > /proc/sys/kernel/hostname

Shalom,

Changing hostname in /etc/sysconfig/network may not require a reboot though recommended.

Making the change and doing a service network restart should be sufficient for most situations, short term.

For do it without reboot, edit /etc/sysconfig/network as menthioned above.

Run:

hostname "newhostname.domain"

Edit /etc/hosts to reflect the changes.

Update DNS servers if necessary.
