-====== Ubuntu - Services - Starting a service ======
-The recommended method to use it at the top of this list, but if that does not work try the other methods.
-===== Using systemctl =====
-<code bash>
-systemctl start service_name.service
-</code>
-Example:
-<code bash>
-systemctl start apache2.service
-</code>
-----
-===== Using System V =====
-With **sysv-rc-conf** or **sysvconfig** under Debian or Ubuntu Linux.
-<code bash>
-/etc/init.d/service_name
-</code>
-Example:
-<code bash>
-/etc/init.d/apache2
-</code>
-----
-===== Using Service =====
-**service** runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /.
-**service** works in most Linux distributions including Debian and Ubuntu.
-<code bash>
-service service_name start
-</code>
-Example:
-<code bash>
-service apache2 start
-</code>
-----
-===== Using invoke-rc.d =====
-**invoke-rc.d** is a wrapper around running the System V style init script **/etc/init.d/name** directly, obeying runlevel constraints as well as any local policies set by the system administrator.
-The policy may cause the command not to be run at all, based on the current runlevel and whether the daemon should be run in that runlevel.
-By default, Debian does not differentiate between runlevels 2-5, but as the local administrator, you can change what is run in each runlevel.  invoke-rc.d will honor these local policies and not start a daemon if the runlevel is wrong.
-According to the man page, all access to init scripts by Debian packages' maintainer scripts should be done through invoke-rc.d.

-  * [http://manpages.ubuntu.com/manpages/xenial/man8/invoke-rc.d.8.html]
-<code bash>
-invoke-rc.d service_name start
-</code>
-Example:
-<code bash>
-invoke-rc.d apache2 start
-</code>
-----
-===== Using Upstart =====
-**Upstart** is an event-based replacement for the /sbin/init daemon which handles starting of tasks and services during boot, stopping them during shutdown and supervising them while the system is running.
-It was originally developed for the Ubuntu distribution, but is intended to be suitable for deployment in all Linux distributions as a replacement for the venerable System-V init.
-**upstart** only works on certain version of Ubuntu.

-<code bash>
-start service_name
