sudo service apache2 restart VS sudo systemctl restart apache2

Question

I'm a new Linux user, I'm using LAMP in Ubuntu 18.04, both orders run equals in appearance.

What is the difference between the next two commands:

sudo service apache2 restart 

sudo systemctl restart apache2

Answer 1

service is used when dealing with old system V init scripts and systemctl for systemd services, etc. I would suggest not dealing with service or system V init scripts anymore, unless it's some legacy application.
