Change HostName
Apr 2023
To change the hostname of an Alma Linux instance, use the following procedure.
First, check the current hostname: from the console enter:
hostname or hostnamectl
This will give an output similar to below:
Static hostname: localhost.localdomain Icon name: computer-server Chassis: server Machine ID: 87b77afdf05948d88282bb44dc1e8386 Boot ID: a7c17a79aa394c2f84758fa133c735cb Operating System: AlmaLinux 8.5 (Arctic Sphynx) CPE OS Name: cpe:/o:almalinux:almalinux:8::baseos Kernel: Linux 4.18.0-348.el8.x86_64 Architecture: x86-64
In this example we can see that the hostname is the default value of localhost.localdomain and we want to change this to something that we can use and recognise.
To set the hostname use the following:
hostnamectl set-hostname 'your-hostname'
For example, lets say I want to change the hostname to be mailsvr, then I would use:
hostnamectl set-hostname mailsvr
We can now check the hostname from the console again using:
hostname or hostnamectl
The hostname returned will now be the one you set (mailsvr) in this example.
