Configure VNC Server on CentOS 7/rhel 7

The following simple guide, "the VNC server on RHEL 7/centos 7 machines, VNC help to share the desktop wit H The other machines which have a client installed. VNC server and client is not a installed by default, you need to setup the VNC server manually.

Before installing the VNC server, let us install Gnome desktop.

[[email protected] ~]# yum groupinstall  "Gnome desktop"

install the TIGERVNC server and X11 fonts.

[[email protected] ~]# yum install tigervnc-server xorg-x11-fonts-type1

copy the VNC server configuration file to/etc/systemd/system/for Configuring the system service. While copying, you can mention which port it should listen. By default VNC server listens on 5900, but if you are setup port-offset for VNC; We can run a service on a sub-port of the default port 5900. For example, if we mention Port 5, it is accessible on 5905.  you can connect the VNC server by specifying Ipadd Ress:sub-port (192.168.2.109:5 or 192.168.2.109:5905)

[[email protected] ~]# cp /lib/systemd/system/[email protected] /etc/systemd/ System/[email protected]:5.service

edit the copied file.

[[email protected] ~]# vi /etc/systemd/system/[email protected]:5.service

at the end of file, you'll find the lines like below.

[unit]
description=remote Desktop Service (VNC)
after=syslog.target network.target[service]
type=forking
# clean any existing files in/tmp/. X11-unix environment
execstart=/sbin/runuser-l <USER>-C"/usr/bin/vncserver%i "
PIDFILE=/HOME/<USER>/.VNC/%H%I.PID
execstop=/bin/sh-c '/usr/bin/vncserver- Kill%i >/dev/null 2>&1 | | : ' [install]
wantedby=multi-user.target

replace <USER> with your real USER, in my case I replaced with USER called "Raj" with the screen size.

[unit]
description=remote Desktop Service (VNC)
after=syslog.target network.target[service]
type=forking
# clean any existing files in/tmp/. X11-unix environment
execstart=/sbin/runuser-l raj-c"/usr/bin/vncserver%i-geometry 1280x1024″
PIDFILE=/HOME/RAJ/.VNC/%H%I.PID
execstop=/bin/sh-c '/usr/bin/vncserver-kill%i >/ Dev/null 2>&1 | | : ' [install]
wantedby=multi-user.target

add firewall rules to allow the VNC connection, the following rule was set as per the Port-offset mentioned in the Previou S step.

[[email protected] ~]# firewall-cmd --permanent --zone=public --add-port=5905/ Tcp[[email protected] ~]# firewall-cmd --reload

start VNC server after switching to Raj.

[[email protected] ~]$ vncserver

Set the password.

You'll require a password to access your desktops.

Password:
Verify:
xauth:file/home/raj/. Xauthority does not exist

New ' Localhost.localdomain:1 (Raj) ' Desktop is server.itzgeek.com:1

Creating default startup Script/home/raj/.vnc/xstartup
Starting applications specified In/home/raj/.vnc/xstartup
Log file Is/home/raj/.vnc/server.itzgeek.com:1.log

Reload the Systemctl daemon as root

systemctl daemon-reload

start the VNC service as root.

systemctl start [email protected]:5.service

enable it on system startup as root.

systemctl enable [email protected]:5.service

take Remote Desktop.

ipaddress:5905 or ipaddress:5
