In CentOS and some other distros you can control hostname using:
$ hostnamectl set-hostname <new hostname> #in CentOS 7 changes /etc/hostname file that stores centrally the computer hostname
In Redhat (RPM) based distros change the hostname permanently by editing:
$ vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=newHostName
In other distros it should be enough to change:
$ vi /etc/hosts 127.0.0.1 newHostName 127.0.0.1 localhost localhost.localdomain ::1 localhost localhost.localdomain
Temporarily changing hostname can be achieved by the command below then logout and login again to see the effect in bash.
$ hostname newHostName
- Restart networking
If you changed /etc/hosts or /etc/sysconfig/network file you want to restart networking to ensure that changes will be persistent on reboot:
$ /etc/init.d/network restart # Redhat based $ sudo service networking restart # Debian/Ubuntu distros
