Use systemctl instead of service command

TLDR;

## Details

I'm a long time Linux user and got a habit to start/stop things using `service` command.

I never really thought about what exactly it does. I mean, I know I can start Apache or something else with it and it's something related to init system of my distro. Usually when you install Apache or PHP-FPM those things become recognizable by `service` command and you can call `service program start` when you want to start a service.

I never really needed to write my own init scripts so I successfully skipped any knowledge related to init systems of various distros I used.

Today I was reading 
=> https://docs.fedoraproject.org/en-US/docs/ Fedora Manual for Administrators
and there are lot of stuff written about systemd and its insisted to use `systemctl` command. Why is that if `service` works too.

Let's close this question.

Turned out `systemctl` is part of `systemd` package/program/init-system. And this is the tool to use when you want to interact with `systemd`.

Most systemd-based distros provide service command for backward compatibility. At first this command is going to look into /etc/init.d folder and if no service found there then it will try to use systemctl.
