To start a Linux service:
[user@domain]# service servicename start
To stop a Linux service:
[user@domain]# service servicename stop
To restart a Linux service:
[user@domain]# service servicename restart
If the above does not work, please notice that:
service
is a short cut for:
/etc/init.d/
So, you might also issue the following command:
[user@domain]# /etc/init.d/servicename start|stop|restart
