This solution will work on all RH-based operating systems.
1. Login to your server as 'root' and run
#vi /etc/hosts - this will open up the /etc/hosts file using VIM editor
2. Change the values after your server's main IP address to reflect your desired hostname. You must put in a valid hostname, one that will resolve as one of the options. Example:
127.0.0.1 localhost
1.1.1.1 myhostname.mydomain.com myhostname
3. After you are finished, save the file by running
:wq
4. When you're back at the prompt, run
#vi /etc/sysconfig/network
5. In the network file, next to your IP, change the current value with your new valid hostname (myhostname.mydomain.com)
6. When you're done, save the file
:wq
If the hostname did not take effect automatically (as it should), issue a server wide reboot for these effects to take change
#shutdown -r now
Wait for the machine to come back up and double check your new hostname by running the #hostname command.
Just to note, you can also check to make sure that /proc/sys/kernel/hostname has also been updated to the new hostname.
I love AYK. been with them for over 5 years and the best ever
I have been with ayksolutions for around 5 years and have been thoroughly impressed with them. All support tickets are answered within minutes, regardless of the time of day. Prices are very reasonable, especially considering the support and services they provide. They are constantly doing crazy deals for servers as well. If you're looking for someone good and reliable to host with, from shared hosting to dedicated servers, I easily recommend ayksolutions.
I have been a client for many years now. They always answer to my needs, and keep their prices affordable. I will continue with them in the future.
