Hello Friends Any One Help Me To Configure Hostname

Actually I created Hostname But I Can't Do This
Update /etc/hosts

Next, edit your /etc/hosts file to resemble the following example, replacing plato with your chosen hostname, example.com with your system's domain name, and 12.34.56.78 with your system's IP address. As with the hostname, the domain name part of your FQDN does not necesarily need to have any relationship to websites or other services hosted on the server (although it may if you wish). As an example, you might host "www.something.com" on your server, but the system's FQDN might be "mars.somethingelse.com."

File:/etc/hosts

127.0.0.1 localhost.localdomain localhost
12.34.56.78 plato.example.com plato
If you have IPv6 enabled on your Linode, you will also want to add an entry for your IPv6 address, as shown in this example:

File:/etc/hosts

127.0.0.1 localhost.localdomain localhost
12.34.56.78 plato.example.com plato
2600:3c01::a123:b456:c789:d012 plato.example.com plato

open putty.
insert your connection details and log in via root-account
then write the following

Code: 
vi /etc/hosts
press i-Button
no edit your settings
if you're done press ESC then write :wq
(with the : )
no you've written your changes to the file.

if you have nano installed do the following:
Code: 
nano /etc/hosts
change your settings
press CTRL+O and then CTRL+X

Thanks a lot Friends

Setting the hostname under CentOS with
Code: 
hostname YOURNAME
Will not persist after a reboot.

1. You must know that the hostname is the name of your server (in very simple terms).
2. Configuring FQDN instead of hostname is not correct. Do not configure the hostname with: name.domain.tld
3. In CentOS the hostname can be configured in this file: /etc/sysconfig/network
Code: 
HOSTNAME=name
4. In /etc/hosts you will have to configure the FQDN for your public IP like this:
Code: 
192.168.1.1 name.domain.tld name
5. By running the command
Code: 
hostname
you should see only the name of your server.
6. By running the command
Code: 
hostname -f
you should see the FQDN like this: name.domain.tld (where name is the actual hostname of your server)

I hope this helps you.
