Note: I've only tested this on a Debian container, and you can't
set these sysctls on containers (the host controls them). To make
matters worse, there is no fact to make ansible skip this on hosts
that are running in containers. For now I will just skip it on
hosts that are "virtualization" servers... even though we actually
do have KVM running on Debian on real hardware. *sigh*

have added translations of the current IPv4 and IPv6 iptables rules.

For security and predictability clients should only get a reponse
if they request a hostname we are actually hosting.
If TLS is in use then this will use a self-signed snakeoil cert for
an HTTPS-enabled blank, default vhost.

New hosts often fail due to not having an apt_mirror, because there
isn't one defined for their group and their host_vars haven't over-
ridden it.
We want new hosts to deploy successfully, so let's just use a default
apt_mirror if there isn't one defined. Rather have a slow mirror than
a failed deployment. And in any case, Linode can download from KENET's
mirror at 10MB/sec. ;)

A template is better than ansible's `apt_repository` module because
we can idempotently control the contents of the file based on vari-

I was only setting it on the PHP block, which is for all dynamic
requests (ie pages from WordPress), but it should also be the same
for all static files not served from that block.

Reduce memory allocation from 128 -> 72M because after a few days
of running it's only using 64 or so, so it's really just a waste of
memory.
Also, disable opcache for CLI. What the hell do you need opcaching
in the CLI invocation for? It only persists for one process!

Adds a default php.ini for php5-fpm from Ubuntu 14.04 which enables
sane settings for PHP 5.5's opcache as well as disables pathinfo.

nginx inherits headers from higher-level blocks UNLESS we also set
headers in the current block. In this case the FastCGI cache header
was being set, so we weren't getting the extra-security ones.

nginx blocks inherit headers set in blocks above them UNLESS the
current level also sets headers[0]. This was causing PHP requests
to not have STS headers because of the FastCGI cache header which
is set in that block.

I think it was originally supposed to be `ansible_os_family` but
we don't have anything other than Ubuntu, so let's just use that.
Signed-off-by: Alan Orth <alan.orth@gmail.com>
nginx is caching HEAD requests, then when users come along and do
a GET request they get an HTTP 200 with no request body. It seems
setting fastcgi_request_methods to GET doesn't stop nginx from caching
HEADs, so for now just add the $request_method to the key.

It's just too tricky to manage this. Ubuntu / RedHat preseeds and
kickstarts can create the user and add it to groups, but only when
we control the initial boot environment (ie not on Linode, Digital
Ocean, etc), so let's just say we assume this user exists and can
get root with sudo by the some we are running ansible on it.

Reduces round trip time for clients. Note: I am using a certificate
chain in the `ssl_certificate' directive, so as I understand it, I
don't need to use an explicit trusted intermediate + root CA cert
with the `ssl_trusted_certificate' option. See the nginx docs for
more[0]. Addresses GitHub Issue #5.
Seems to be working, test with:
$ openssl s_client -connect mjanja.ch:443 -servername mjanja.ch -tls1 -tlsextdebug -status
Look for "OCSP Response" with "Cert Status: good".

Default is 5 minutes, but it seems like unless you're a high-traff-

Use "public" with "max-age" instead of Expires, as "max-age" is always
preferred if it's present. Note: setting "public" doesn't make the
resource "more cacheable", but it is just more explicit.

My WordPress blogs have a /wordpress subdirectory in the document
root, but I don't serve from the /wordpress URI.
Technically, all we need is the tweaks to the try_files:
- `?args` passes query strings to php5-fpm
- removing 404 from the vhost's try_files so we don't return 404
when the requested file doesn't exist (obviously not all request
URI's in WordPress are actual files on the disk)

Assumes you have a TLS cert for one domain, but not the others, ie:
http://blah.com \
http://blah.net -> https://blah.iohttp://blah.org /
Otherwise, without https, it creates a vhost with all domain names.
