Check the service status

A service can have any of the following statuses:

• start: The service has started.

• stop: The service has stopped running.

• restart: The service is rebooting and will start after the process is complete.

Many times, you may have another service listening on the port, which may prevent the service from starting. To find out what’s listening, use the netstat command.
