Install VNC server on Azure Linux VM(RHEL/OEL/CENTOS) with Demo Video

In this post I am going to share how to install vnc server on a Azure VM having Linux OS(RHEL/Centos/OEL). This can be performed on on-premises Linux servers as well.

Steps:

All steps I have performed using root user.

1) Install the required RPMS

yum install tigervnc-server

yum install xterm

yum install xclock

2)Install the GUI Graphic mode in Linux by default its not installed. It will take 15-20 minutes (optional only)

yum -y group install GNOME base-x

3)Set the Password for VNC for current User.

$ vncpasswd

Example:

[root@myebs1 ~]$ vncpasswd

Password:

Verify:

Would you like to enter a view-only password (y/n)? n

A view-only password is not used

[root@myebs1 ~]$

4) Enable the firewall for the 5901 ports.

firewall-cmd --permanent --add-port=5901/tcp

firewall-cmd --reload

Example:

[root@myebs1 ~]$ firewall-cmd --permanent --add-port=5901/tcp

success

[root@myebs1 ~]$ firewall-cmd --reload

success

5) Start the VNCSERVER service.

$ vncserver

Example:

[root@myebs1 ~]$ vncserver

xauth: file /home/root/.Xauthority does not exist

New 'myebs1:1 (root)' desktop is myebs1:1

Creating default startup script /home/root/.vnc/xstartup

Creating default config /home/root/.vnc/config

Starting applications specified in /home/root/.vnc/xstartup

Log file is /home/root/.vnc/myebs1:1.log

6) Check VNC server start listening with following command:

[root@myebs1 ~]$ netstat -tlnp

(Not all processes could be identified, non-owned process info

will not be shown, you would have to be root to see it all.)

Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp 0 0 0.0.0.0:5355 0.0.0.0:* LISTEN -

tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN 35193/Xvnc

7) New Inbound Network rule.

Go to the Network security Setting in Azure Portal. Add new inbound network policy for PORT 5901 with 320 priority for that virtual machine. It will enable the PORT 5901 for incoming connection to VM.
