Setting a hostname on your Virtual Private Server (VPS) is an essential step in establishing a recognizable and unique identity for your server. A hostname helps you easily identify and locate your VPS when managing multiple servers or when interacting with other network devices. In this article, we will guide you through the process of setting a hostname on your VPS.
Step 1: Choosing a Hostname
Selecting an appropriate hostname is crucial. It should be unique, easy to remember, and relevant to your server’s purpose. Ideally, it should consist of lowercase letters, numbers, and hyphens. For example, “myserver” or “web-01” are suitable hostnames.
Method 1
Step 1: Accessing Your VPS
To begin, you need to establish a connection to your VPS. This can be done using SSH (Secure Shell) or a web-based control panel provided by your hosting provider. Once you have logged in, you will have access to the command line interface.
Step 2: Editing the Hostname File
In most Linux distributions, the hostname is stored in a file called /etc/hostname. To change the hostname, use a text editor such as nano or vim to open the file:
sudo nano /etc/hostname
Within the file, you will find the current hostname. Delete the existing hostname and enter your desired hostname. Save the changes and exit the editor.
Step 3: Updating the Hosts File
Next, you need to update the /etc/hosts file to associate the new hostname with the server’s IP address. Open the file in a text editor:
sudo nano /etc/hosts
Locate the line that starts with your server’s IP address, followed by the old hostname. Replace the old hostname with the new hostname. Save the changes and exit the editor.
Step 4: Applying the Changes
To apply the new hostname, you will need to restart the server.
sudo reboot
Step 5: Verifying the Hostname
To verify that the hostname has been successfully changed, use the following command:
hostname
The output should display your new hostname.

Step 2: Accessing Your VPS
To begin, you need to establish a connection to your VPS. This can be done using SSH (Secure Shell) or a web-based control panel provided by your hosting provider. Once you have logged in, you will have access to the command line interface.
Step 3: Using the ‘hostnamectl’ command
you can update your hostname using the hostnamectl command. Execute the following command:
sudo hostnamectl set-hostname your_new_hostname
Replace your_new_hostname with your desired hostname. This command will immediately update the hostname without requiring a server restart.
Step 4: Verifying the Hostname
To verify that the hostname has been successfully changed, use the following command:
hostname
The output should display your new hostname.
Step 5: Applying the Changes
To apply the new hostname, you will need to restart the server.
sudo reboot
Conclusion:
Setting a hostname on your VPS is a simple yet important task that allows you to identify and manage your server efficiently. By following the steps outlined in this article, you can easily set a hostname on your VPS and establish a distinct identity for your server. Remember to choose a unique and meaningful hostname that aligns with your server’s purpose.
