Solved: How to change hostname using nmtui or nmcli in redhat linux

In our last post we have seen how to change hostname manually or with hostnamectl .

In this post we will discuss how to change hostname with nmtui and nmcli tools.

nmtui

Let’s first try with nmtui tool

  • If you don’t have the nmtui tool installed, you can install it using yum
yum install NetworkManager-tui
  • Invoke the nmtui interface from the command line by executing as root user
nmtui
  • In the menu select “Set system hostname” as shown below

  • Write the new hostname which you want to keep.  We want to change it to “prodvedas”.

  • To make it effective restart the “hostnamed” service
systemctl restart systemd-hostnamed
  • Now if you login with new session or do “su -” in same session you should see new hostname.

Let’s try changing the hostname with nmcli tool in Redhat Linux.

  • To check the current hostname
nmcli general hostname
  • If you want to change the hostname
nmcli general hostname prodvedas
  • To make it effective restart hostnamed service
systemctl restart systemd-hostnamed
  • Now if you login with new session or do “su -” in same session you should see new hostname.

Hostname changed by any of the above method will be persistent across reboot.
