Ubuntu 'Failed to restart apache2.service: Unit apache2.service not found.'

Question

I am using Google Cloud Platform to test out ModSecurity and I am using a tutorial to launch it. However, I need to restart Apache every once in a while. I'm using Ubuntu 18.04. I write sudo systemctl restart apache2, but an error comes back and it says Failed to restart apache2.service: Unit apache2.service not found. What should I do?

Answer 1

Did you install apache2 first ?

sudo apt install apache2

Answer 2

For those who run into the same issue using Debian

I did have apache2 installed and running as was confirmed by apache2.service | loaded active running.

I still tried to install it.

I did also get the same error Failed to restart apache2.service: Unit apache2.service not found

How I got apache2 to restart

Using: Debian (9.13)

sudo service apache2 restart

or by typing

sudo apachectl stop
sudo apachectl start
