Add automated tests for Debian 8, fix systemd not enabling

[geerlingguy]

I've been hitting an issue with the php7.1-fpm service not showing as enabled via systemctl status over in Drupal VM (when building a Docker container for the VM)—see geerlingguy/drupal-vm#1366, the first issue in that list.

Then I realized I don't have any automated test coverage in this repo, and that's probably why there are little broken things like this! I need to add automated test coverage, fixing any issues that are exhibited by said tests.

[geerlingguy]

Funny enough... tests are passing locally without me changing anything, even though when I check inside the container:

root@7da2a033d088:/# systemctl status php7.0-fpm
● php7.0-fpm.service - The PHP 7.0 FastCGI Process Manager
   Loaded: loaded (/lib/systemd/system/php7.0-fpm.service; disabled)
   Active: inactive (dead)
     Docs: man:php-fpm7.0(8)

root@7da2a033d088:/# php -v
Cannot load Zend OPcache - it was already loaded

So I should probably add in a test to verify the service is actually enabled. Or at least file a bug (or find an existing bug) with Ansible's service module on Debian 8 systemd...

Yay, I got the Debian 8 test to fail, while it's working on other systemd distros :)

Any chance it's this one ansible/ansible-modules-core#3764 (comment)

[oxyc]

Seems that was the bug, https://travis-ci.org/geerlingguy/ansible-role-php/jobs/232887274#L756

Can't really go with use: service though as it requires Ansible 2.2 and wont work on all systems.

The upstream issue ansible/ansible#22303

[geerlingguy]

@oxyc - D'oh! Well, another option is to:

• Bump the role to 2.2 (many of my roles are there already :)
• Add a when on the existing service task and set it to 'not debian / not jessie' (something like that)
• Add a second service task with a link to that upstream issue (# See [url]) and the use: service.

(If you want to make those changes in your PR I'll merge it and close my original one)

I was just debugging a bit while waiting for a provision to finish at work (production drupal vm 🎉) :) Feel free to fix it, otherwise I can take a look later after I finish work.
