New page

== Previously and Now.. ==

In the old versions of Redhat services that used the SysV or upstart, had corresponding init scripts found in /etc/rc.d/init.d/ directory. These scripts could be modified as they were written in bash, and allowed the admin to control how and when the servics were started.

The init scripts have been replaced with systemd serice units. Each service unit ends with the .service file extension, but serve a similar purpose to the old init scripts.

The service units are used with the systemctl command, and while the service and chkconfig commands still exist they should be avoided.

== Comparison of the service and systemctl commands ==

The examples below use the full .service notation, however the services can controlled while omitting this.
