========================================

Change hostname in Linux

First you need to find out your hostname, you can do this with

$ hostname

localhost.localdomain

$

Edit /etc/hosts

You need to edit /etc/hosts and add a line for your host name

$ cat /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1               localhost.localdomain localhost

$

My new server IP is 72.232.196.90, i need to assign it hostname server12.hosthat.com, to do this, i have edited /etc/hosts as follows.

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1               localhost.localdomain localhost

72.232.196.90           server12.hosthat.com server12

Edit /etc/sysconfig/network

First lets see what is in the file

$ cat /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=localhost.localdomain

$

To change servers hostname to server12.hosthat.com, change the file as follows.

$ cat /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=server12.hosthat.com

$

Now you need to reboot the server to change the hostname.
