# hostname prod-server
- Modify the /etc/hosts file
If you have entries in the /etc/hosts file with the old hostname, you should modify it.
For example, the entry for 127.0.0.1 line in the /etc/hosts file will still show the old hostname. In this example, it shows as dev-server.
$ cat /etc/hosts 127.0.0.1 dev-server localhost.localdomain localhost
Modify this file, and set the new hostname here. For example, change dev-server to prod-server as shown below.
$ cat /etc/hosts 127.0.0.1 prod-server localhost.localdomain localhost
- Modify the /etc/sysconfig/network file
The /etc/sysconfig/network file also has an entry for HOSTNAME. Change the value here as shown below.
# cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=prod-server
- Restart the Network
Restart the network service, if you want any other services that are using the hostname to pickup the changes.
# service network restart Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: [ OK ]
If its still not work than restart the system than in startup it will set.
Hope this will help
