hostnamectl | hostnamectl | ||

+ | This will give an output similar to below: | ||
+ | \\ | ||
+ | < | ||
+ | | ||
+ | Icon name: computer-server | ||
+ | | ||
+ | Machine ID: 87b77afdf05948d88282bb44dc1e8386 | ||
+ | Boot ID: a7c17a79aa394c2f84758fa133c735cb | ||
+ | Operating System: AlmaLinux 8.5 (Arctic Sphynx) | ||
+ | CPE OS Name: cpe:/ | ||
+ | Kernel: Linux 4.18.0-348.el8.x86_64 | ||
+ | Architecture: | ||
+ | </ | ||
+ | In this example we can see that the hostname is the default value of <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | To set the hostname use the following: | ||
+ | hostnamectl set-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. | ||
+ | \\ | ||
+ | \\ | ||
+ | We also need to edit the following file: | ||
+ | /etc/hosts | ||
+ | \\ | ||
+ | \\ | ||
+ | Add a line at the end of the file with your <color # | ||
+ | < | ||
+ | 127.0.0.1 | ||
+ | ::1 | ||
+ | 150.10.10.1 | ||
+ | </ | ||
+ | \\ | ||
+ | \\ | ||
+ | Now reboot the Alma Linux instance. | ||
+ | \\ | ||
+ | \\ | ||
+ | When you log back in, you should see your command prompt now contains your hostname: | ||
+ | [root@mailsvr /]# | ||
+ | \\ | ||
+ | \\ | ||
+ | Hostname setting is complete. | ||
