How to change hostname of a CentOS system?
CentOS is an Enterprise Linux distribution based on the freely available sources from Red Hat Enterprise Linux. Each CentOS version is supported for 7 years (by means of security updates). A new CentOS version is released every 2 years and each CentOS version is periodically updated (roughly every 6 months) to support newer hardware. This results in a secure, low-maintenance, reliable, predictable and reproducible Linux environment.
I personally prefer to install CentOS as my linux distribution. Today I needed to change the hostname of my virtual guest machine running CentOS.
There are several ways to do that but I am using the old way. VI is my friend and still working. I am using a remote SSH session to one of my virtual machines but you can perform same steps from the console.
- Login with putty.exe
- Goto /etc/sysconfig/
- Type vi network
- Press i on the keyboard and change the HOSTNAME to your preferred servername
- Press ESC on the keybord
- Save the configuration by :wq!
- Log off or reboot
