Nginx + Passenger on Gentoo15 Jan 2016
From the “niche interest” desk:
Nginx builds all of it’s components into one executable (they argue that it’s necessary for their level of speed and security). Gentoo lets you configure software all kinds of ways, so it’s pretty easy to configure exactly which of the myriad of modules you want to install. But like every Linux distro, they’ve had an ongoing tete-a-tete with Rubygems, so Passenger isn’t supported out of the box in the Gentoo set of options. Passenger’s idea of installing itself into Nginx is to recompile the whole thing - without respecting the modules that were already installed.
It’s a headache, and I’ve given up trying to assign blame - I think probably everyone solved the (very large) problems in front of them, and it happens that their solutions don’t interact well. (Gentoo Rubyists (and yes, I’m sure the plural there is optimistic): I’m liking chruby + direnv + bundler as an adjunct to eselect.)
But, there’s a couple of hidden outs that make it entirely feasible to get a respectable nginx/passenger deploy going on Gentoo, which I’ll record here for my own purposes, at least.
In /etc/nginx/nginx.conf, add:
