Deploy Rails app to digitalocean with nginx, unicorn, capistrano & postgres

Create droplet of your liking (ubuntu 12.10 x32)

ssh to root in terminal with your server ip

ssh [email protected]

Add ssh fingerprint and enter password provided in email

Make /robots.txt aware of the Rails environment

You probably don't want Google crawling your development staging app. Here's how to fix that.

$ mv public/robots.txt config/robots.production.txt
$ cp config/robots.production.txt config/robots.development.txt

Now edit config/routes.rb to add a route for /robots.txt, and add the controller code.

Введение

Начать стоит отсюда. Не пугайтесь то, что это книга по незнакомой OS, эти термины практически везде одинаковые и здесь они изложены в понятной для начинающих форме.

http://www.qnx.com/developers/docs/6.4.1/neutrino/getting_started/s1_procs.html

Прочесть нужно треть главы до подраздела "Starting a process", если С не пугает, читайте полностью. После прочтения вы будете понимать, что такое process, thread, mutex, priorites, semaphores, scheduler, contex-switch, kernel states.
