His task: Configure network services to start automatically at boot

Andreas is a master of training. His task: to teach a class of RHEL interns how to configure network services to start automatically at boot on a RHEL server.

Please generate and explain all of the commands that Andreas will need to execute to complete this task.

To configure network services to start automatically at boot on a RHEL server, Andreas can follow these steps:

Step 1: Identify the network service

  • Determine the network service that needs to start automatically at boot. For example, let's consider the "httpd" (Apache HTTP Server) service.

Step 2: Check the service status

  • Before configuring the service to start at boot, it's important to check the current status of the service to ensure it is installed and running:
  • $ systemctl status httpd

Step 3: Enable the service

  • Use the systemctl command with the enable option to enable the service to start automatically at boot:
  • $ sudo systemctl enable httpd

Step 4: Verify the service configuration

  • Confirm that the service is set to start at boot by checking the enabled status:
  • $ systemctl is-enabled httpd

Step 5: Reboot the server

  • Reboot the RHEL server to ensure that the configured network service starts automatically at boot:
  • $ sudo reboot

Step 6: Check the service after reboot

  • After the server restarts, verify that the network service has started automatically:
  • $ systemctl status httpd

By following these steps, Andreas can configure a network service, such as the Apache HTTP Server, to start automatically at boot on a RHEL server. He can apply the same process to other network services as needed, adjusting the specific service name accordingly.

It's worth mentioning that Andreas should ensure he is running these commands with the appropriate privileges and as a non-root user, as per his professional preference.
