However, many enterprise systems, for example, IBM Power Systems and IBM Z, are located in remote data center environments that are run autonomously and are not connected to a display, keyboard, and mouse. These systems are often referred to as headless systems and they are typically controlled over a network connection. The RHEL installation program includes a Virtual Network Computing VNC installation that runs the graphical installation on the target machine, but control of the graphical installation is handled by another system on the network.

Once a connection is established, the two modes do not differ. The mode you select depends on your environment. VNC client applications are available in the repositories of most Linux distributions, and free VNC client applications are also available for other operating systems such as Windows.

Network and firewall:. In this procedure, the system with the VNC viewer is called the remote system. You are prompted by the RHEL installation program to initiate the connection from the VNC viewer on the remote system to the target system. Specific instructions for other viewers might differ, but the general principles apply. As root, you have installed a VNC viewer on a remote system, for example:.

Append the inst. If you want to restrict VNC access to the system that is being installed, add the inst. The VNC password must be between 6 and 8 characters long. Use a temporary password for the inst. Specific instructions for other viewers might differ, but the general principles apply.

The VNC password must be between 6 and 8 characters long. Use a temporary password for the inst. It should not be an existing or root password. Press Enter to start the installation. The target system initializes the installation program and starts the necessary services. When the system is ready, a message is displayed providing the IP address and port number of the system.

From this window, you can install CentOS 8 on the target system using the graphical user interface. For more information on how to perform a CentOS 8 installation using the graphical user interface, see the Installing using the Graphical User Interface section in the Performing a standard installation document.

In Connect mode, the target system that is being installed with CentOS initiates a connect to the VNC viewer that is installed on another system. You have set up a network boot server to start the installation on the target system. You have configured the target system to use the boot options for a VNC Connect installation.

For more information, see add link to updated boot options when they are ready. You have verified that the remote system with the VNC viewer is configured to accept an incoming connection on the required port.
