Start, stop, and check the status of network services

Meghan is a RHEL Sysadmin at IBM. She is teaching the following topic to a class of new hires: Start, stop, and check the status of network services. Please generate and explain several commands that Meghan (username: meghanq) can demonstrate on her RHEL Server: RHEL_Server_812. Meghan is highly seasoned: she NEVER runs commands as root.

Certainly! Here are several commands that Meghan can demonstrate to the class of new hires for starting, stopping, and checking the status of network services on her RHEL Server (RHEL_Server_812) without running commands as root:

1. To start a network service:

   • systemctl start <service_name>

   • Example: systemctl start httpd to start the Apache HTTP server.

     This command will start the specified network service. Replace <service_name> with the actual name of the service you want to start.

2. To stop a network service:
   • systemctl stop <service_name>

   • Example: systemctl stop httpd to stop the Apache HTTP server.

     This command will stop the specified network service. Replace <service_name> with the actual name of the service you want to stop.

3. To check the status of a network service:
   • systemctl status <service_name>

   • Example: systemctl status httpd to check the status of the Apache HTTP server.

     This command will display the current status of the specified network service. Replace <service_name> with the actual name of the service you want to check.

4. To enable a network service to start automatically on boot:
   • systemctl enable <service_name>

   • Example: systemctl enable httpd to enable the Apache HTTP server to start on boot.

     This command will configure the specified network service to start automatically when the system boots up. Replace <service_name> with the actual name of the service you want to enable.

5. To disable a network service from starting automatically on boot:
   • systemctl disable <service_name>
   • Example: systemctl disable httpd to disable the Apache HTTP server from starting on boot.
     
     
   • This command will configure the specified network service to not start automatically when the system boots up. Replace <service_name> with the actual name of the service you want to disable.

By demonstrating these commands, Meghan can teach the new hires how to manage network services effectively without the need for root privileges.
