It's finally colocated onto this box, instead of being on the old
server! I think I'm noticing substantial perf improvements, probably
both from increased colocation (tho they were in the same house
before), and also from like ten years of performance optimizations LOL!
As part of this, I created a new `setup_secrets.yml` file that's
similar to `production.env`, but is for values that the setup script
itself needs access to, whereas `production.env` is for values that the
app needs at runtime. (Though they have some things in common, like the
MySQL user password!) It's gitignored for security, as per usual!
Yay it's working! We set up the box, install Ruby, upload a placeholder app, set it up as a service, and get it hooked up to nginx!
Next, we'll add the script to upload the latest version of the site. We just need to slot it into `/srv/impress/current`, run `bundle install`, and that should basically be that! (Oh, and we need to compile production assets—I wonder if it's useful to do that on the dev machine instead of on the target? That might save us from needing to install Node. Or maybe we'll have to anyway!)
