Notify systemd that we created a new unit file with: sudo systemctl daemon-reload Description = Remote desktop service (VNC) After = syslog.target network.target Type = forking User = linuxize Group = linuxize # Clean any existing files in /tmp/.X11-unix environment ExecStartPre = /bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' ExecStart = /usr/bin/vncserver %I PIDFile = /home/linuxize/.vnc/%H%i.pid ExecStop = /bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' WantedBy = multi-user.target To do so open the following file: nano ~/.vnc/xstartupĪnd change the last line from exec /etc/X11/xinit/xinitrc to exec startxfce4: Now that both Xfce and TigerVNC are installed on the server the next step is to configure TigerVNC to use Xfce. In this case, the server is running in port 5901 ( :1), so we’ll stop it with: vncserver -kill :1 Killing Xvnc process ID 2432

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 with vncserver it will run on the next free port i.e :2, which 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.

Type the following command to install TigerVNC on your CentOS server: sudo yum install tigervnc-server Is an actively maintained high-performance open-source VNC server. We’ll be using TigerVNC as our VNC server of choice.

Once the repository is added, install Xfce on your CentOS with: sudo yum groupinstall xfceĭepending on your system, downloading and installing the Xfce packages and dependencies may take some time. If the repository is not enabled on your server, you can enable it by typing: sudo yum install epel-release Xfce packages are available in the EPEL repository It is fast, stable, and low on system resources, which makes it ideal for usage on remote servers. Installing Xfce Desktop Environment #ĬentOS server installations often do not come with a desktop environment installed, so we’ll start by installing a lightweight desktop environment. We will assume you are logged in as a user named linuxize.
