Changing Default Hostname
Changing Default Hostname
The default hostname is the hostname you choose for your VPS once you purchased it. Which should look something like hostname.example.com. Should you want to change the default name after you set up your VPS then follow this simple tutorial.
The following command under BASH will show you the current hostname.
[user@localhost ~]$ uname -n
localhost.localdomain
Step 1: Add an A record to the DNS records
At your DNS control panel add an A record to your new subdomain and point it to the IP address of your VPS. Usually this is done where you purchased your domain name at. There are many free alternative DNS hosting, however, I recommend using Cloudflare Free DNS Hosting
Select A Record for Type and enter the Host you would like to point to an IP address:
[naurus] – you can insert any name of a subdomain that should be pointed to the IP address:
A Record | naurus | 11.22.33.44
Step 2: Changing the Hostname on the VPS
The following commands can be used for changing the hostname for both CentOS 7.x and Ubuntu 16.04. As root user in CLI edit file at /etc/hostname. Using nano, vi or pico text editor:
[user@localhost ~]$ sudo vim /etc/hostname
Only add the hostname here nothing else;
naurus.example.com
You can also use the hostnamectl command to check and change the hostname too.
[user@localhost ~]$ hostnamectl --help
hostnamectl [OPTIONS...] COMMAND ...
Query or change system hostname.
-h --help Show this help
--version Show package version
--no-ask-password Do not prompt for password
-H --host=[USER@]HOST Operate on remote host
-M --machine=CONTAINER Operate on local container
--transient Only set transient hostname
--static Only set static hostname
--pretty Only set pretty hostname
Commands:
status Show current hostname settings
set-hostname NAME Set system hostname
set-icon-name NAME Set icon name for host
set-chassis NAME Set chassis type for host
set-deployment NAME Set deployment environment for host
set-location NAME Set location for host
[user@localhost ~]$
To set the hostname:
[user@localhost ~]$ sudo hostnamectl set-hostname naurus.example.com
Edit /etc/hosts file and append a new entry to existing entries associated to your server’s main IP address i.e. 11.22.33.44 to the new hostname
11.22.33.44 naurus.example.com naurus
Finally add type in the command
[user@localhost ~]$ sudo hostname naurus.example.com
Then, restart network using the systemctl command:
sudo systemctl restart network
You can check the changes by typing this command again:
[user@localhost ~]$ uname -n
If all went well then you should see your new hostname:
naurus.example.com
Congratulations!
