Greetings, readers. In this article, we will show you how to install VNC on Ubuntu server. VNC is a software that allows remote access and control of a computer from another device. With VNC, you can remotely manage your Ubuntu server from your computer or mobile device. This is a useful tool for system administrators, developers, and anyone who needs remote access to their server.
Before we start, please note that this article assumes that you have a basic knowledge of Ubuntu server and command-line interface. We also recommend that you have root access to your server for easier installation and configuration.
Now, let’s begin with the installation process.
Installation
The first step in installing VNC on Ubuntu server is to update the system packages. Open the terminal on your server and run the following command:
Command
Description
sudo apt-get update
Updates the package lists for upgrades and new packages.
This command updates the package lists on your server, which will ensure that you have the latest versions of the software available for installation.
Next, install the VNC server on your Ubuntu server by running the following command:
Command
Description
sudo apt-get install vnc4server
Installs the VNC server on your Ubuntu system.
This command will install the VNC server package on your Ubuntu system. Once the installation is complete, you can proceed to configure the VNC server.
Configuration
The configuration of VNC server involves creating a password and configuring the VNC server settings. Let’s start by creating a VNC password by running the following command:
Command
Description
vncpasswd
Creates a VNC password for the current user.
This command will prompt you to enter a password for VNC. Type a strong password and confirm it. Note that the password will be stored in plain text format, so make sure to use a strong and unique password.
Once you have created the VNC password, you need to configure the VNC server settings. Create a new file called xstartup in your home directory by running the following command:
Command
Description
touch ~/.vnc/xstartup
Creates a new file called xstartup in the .vnc directory.
Open the xstartup file in your preferred text editor and add the following lines:
Save and close the xstartup file. Now, you can start the VNC server by running the following command:
Command
Description
vncserver :1
Starts the VNC server on display :1.
This command will start the VNC server on display :1. Note that the :1 indicates the display number, which can be changed to any number as long as it’s available.
Once the VNC server is running, you can connect to it from your computer or mobile device using a VNC viewer software. We recommend using RealVNC, TigerVNC, or TightVNC, which are all compatible with Ubuntu.
