I am by no means a devops guy, and this is just a quickly whipped together t1.micro instance with haproxy/nginx/php-fpm/wp/whatever, that's been built using tutorials of questionable quality (as it turned out now) that I found online.

So there probably won't be too much value in a post like that. All I did was setting some sane parameters for Fast CGI stuff in nginx, some for php-fpm and the db.
