Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

Rails 4 Upgrade Notes

I recently completed our upgrade to Rails 4. Below are various notes and links that may help you if you are upgrading your application to Rails 4. YMMV.

Overview

There is a good Rails Guide on upgrading, with a specific section on upgrading from Rails 3.2 to Rails 4.0. First, a bit about our specific application and the technologies used, pre-Rails 4 upgrade:

Rails 3.2.14
Ruby 2.0.0-p247

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Python 2.x

$ python -m SimpleHTTPServer 8000

Technology

Using Homebrew versions in place of rbenv/rvm

Installation

For the git checkout commands we'll want to be in /usr/local. Let's go there now:

cd /usr/local

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

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.

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.

	1. Open a command prompt and navigate to /etc/nginx/ssl

	2. Issue "openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr"

	3. Get your certificate issued - Go to your certificate authority and give them the CSR (server.csr)

	4. Copy your new crt (that the certificate authority issued) to the /etc/nginx/ssl and give it read priveledges

	5. Reconfigure your nginx.conf, here is mine. The first part redirects 80 to 443, the second part listens to 443 and is optimized to return Ruby on Rails application requests using gzip and unicorn.
