Only vhosts running WordPress, etc need PHP. Make sure to set the
appopriate variables for each vhost in the host's vars, ie:
nginx_vhosts:
- domain_name: example.com
has_wordpress: True
- domain_name: example.net
needs_php: True
You can set either of them, but not both—needing WordPress implies
needing PHP.
This reverts commit 201165cff6.
Turns out this actually breaks initial deployments, because the
cache gets updated in the first task, then you add sources for
nginx and mariadb, but it doesn't update the indexes because the
cache is < 3600 seconds old, so you end up getting the distro's
versions of nginx and mariadb.
I have added cache_valid_time=3600 for the first task in each
tag that could be possibly running apt-related commands. For ex,
the "nginx" tag is also in the "packages" tag, but sometimes you
run the nginx tag by itself (perhaps repeatadely), so you'd want
to limit the update unless the cache was 1 hour old
For idempotence we need to run all apt-related tasks, like editing
source files, adding keys, installing packages, etc, when running
the 'packages' tag.
