In this guide we’ll explain how to install and configure VNC Remote Access in latest release of CentOS 7 and RHEL 7 Desktop edition via tigervnc-server program.
VNC (Virtual Network Computing) is a server-client protocol which allows user accounts to remotely connect and control a distant system by using the resources provided by the Graphical User Interface.

Installing GNOME Desktop on CentOS is faily straightforward. Most CentOS servers are run on CLI (Command-Line Interface) mode.
Unlike other VNC servers available which connects directly to the runtime desktop, such as VNC X or Vino, tigervnc-vncserver uses a different mechanism that configures a standalone virtual desktop for each user.
RequirementsStep 1: Install and Configure VNC in CentOS 7
1.Tigervnc-server is a program which executes an Xvnc server and starts parallel sessions of Gnome or other Desktop Environment on the VNC desktop.
A started VNC user session can be accessed by same user from multiple VNC clients. Globe tattoo broadband installer. In order to install TigerVNC server in CentOS 7, open a Terminal session and issue the following command with root privileges.
2. After, you’ve installed the program, login with the user you want to run the VNC program and issue the below command in terminal in order to configure a password for the VNC server.
Be aware that the password must be at least six characters length.

3. Next, add a VNC service configuration file for your user via a daemon configuration file placed in systemd directory tree. In order to copy the VNC template file you need to run the following command with root privileges.
If your user is not granted with sudo privileges, either switch directly to root account or run the command from an account with root privileges.
4. On the next step edit the copied VNC template configuration file from /etc/systemd/system/ directory and replace the values to reflect your user as shown in the below sample.

Also, check VNC service status and enable the VNC daemon system-wide by issuing the below commands.
6. To list the opened ports in listening state owned by the VNC server, run the ss command, which is used in CentOS 7 to display network sockets. Because you’ve only started one instance of VNC server, the first open port is 5901/TCP.
Again, the ss command must be executed with root privileges. In case you start other VNC instances in parallel for different users, the port value will be 5902 for the second, 5903 for the third and so on. The ports 6000+ are used for allowing the X applications to connect to the VNC server.
