hostname issue, cant change it properly

slowerogue · 06-03-2013, 02:17 AM

i have two machine, both are same version rhel6.4

serverB, installed the server by default hostname, localhost.localdomain

hostname -s
localhost

hostname
localhost.localdomain

can i change the hostname without edit /etc/sysconfig/network

because my serverA, i change the hostname during installation.
/etc/sysconfig/network is showing hostname=localhost.localdomain, but when i type hostname, it shows serverA

Yes you can change the hostname without editing the /etc/sysconfig/network file, but it will not persist a system reboot. For example

Code:

serv1#hostname server1

Would change the hostname from serv1 to server1 but after the system reboot it would revert back to serv1 if hostname specified in /etc/sysconfig/network is serv1.

You can put it in /etc/sysconfig/network

Code:

NETWORKING=yes
HOSTNAME=boole

You may also want to put the FQDN and IP in /etc/hosts if you haven't got DNS

Code:

# HW eth0
192.168.1.100	boole.hw.net.local boole
