How to Change Your VPS Hostname

The hostname is the name assigned to your VPS. You may want to change it to match your domain name or server purpose.

Step 1: Connect to Your VPS via SSH

Login to your VPS using SSH:

ssh root@YOUR_VPS_IP

Enter your password when prompted.

Step 2: Check Current Hostname

To see the current hostname of your VPS, run:

hostname

Step 3: Change the Hostname

Use the following command to set a new hostname:

hostnamectl set-hostname your-new-hostname

Example:

hostnamectl set-hostname server1.example.com

Step 4: Update the Hosts File (Recommended)

Edit the hosts file:

nano /etc/hosts

Find the line similar to:

127.0.0.1 localhost

Add or update the hostname entry if needed.

Example:

127.0.0.1 localhost
127.0.1.1 server1.example.com server1

Save the file and exit.

Step 5: Verify the New Hostname

Run the following command to confirm the change:

hostnamectl

Your new hostname should now appear.

Important Notes

• Hostname changes usually take effect immediately.

• Some applications may require a server restart to recognize the new hostname.
