![]() ![]() The the display port on which the VNC service will listen. Start the VNC service and enable it at boot: systemctl -user enable -now Notify systemd that a new user unit file exist: ![]() Generally, the best location to store user unit files is ~/.config/systemd/user. Unit files allow you to easily start, stop, and restart services. # securitytypes=vncauth,tlsvnc # desktop=sandbox geometry =1920x1080 # localhost # alwaysshared Copy The VNC server uses the ~/.vnc/xstartup file to launch applications when creating a new desktop. Now that both Gnome and TigerVNC are installed on the remote CentOS machine, the next step is to configure TigerVNC to use Gnome. In our case, the server is running in port 5901 (:1), so to stop it, run: vncserver -kill :1 Killing Xvnc process ID 19681 What is important to remember is that when working with VNC servers, :X is a display port that refers to 5900+X.īefore continuing with the next step, first stop the VNC instance using the vncserver command with a -kill option and the server number as an argument. If you create a second instance, it will run on the next free port i.e :2, whic means that the server is running on port 5902 (5900+2). In our case, the server is running on TCP port 5901 (5900+1). This indicates the display port number on which the VNC server is running. Note the :1 after the hostname in the output above. The first time the vncserver command is run, it will create and store the password file in the ~/.vnc directory which will be created if not present. Starting applications specified in /etc/X11/Xvnc-session New ':1 (linuxize)' desktop at :1 on machine usr/bin/xauth: file /home/linuxize/.Xauthority does not exist Would you like to enter a view-only password (y/n)? n You will require a password to access your desktops. If you choose to set up a view-only password, the user will not be able to interact with the VNC instance with the mouse and the keyboard. ![]() You will be prompted to enter and confirm the password and whether to set it as a view-only password. Do not use sudo when running the following command: Once the VNC server is installed, run the vncserver command to create the initial configuration and set up the password. It is available in the default CentOS repositories, to install it type: sudo dnf install tigervnc-server TigerVNC is an actively maintained high-performance open-source VNC server. Run the following command to install Gnome, the default desktop environment in CentOS 8 on your remote machine: sudo dnf groupinstall "Server with GUI"ĭepending on your system, downloading and installing the Gnome packages and dependencies may take some time. ![]() If the machine you want to connect to doesn’t have GUI, the first step is to install it. Generally, servers don’t have a desktop environment installed. To follow along with this guide, you need to be logged in as a user with sudo privileges on your remote CentOS machine. We’ll also show you how to securely connect to the VNC server through an SSH tunnel. This article covers the steps to install and configure a VNC server on CentOS 8. Virtual Network Computing (VNC) is a graphical desktop sharing system that allows you to use your keyboard and mouse to remotely control another computer. ![]()
