独角兽脚本中的环境变量

Question

I want to configure the worker processes depending on the environment. But how should I use the condition in unicorn script wrt environment variabes.

I have used following code but does not work -

if ENV['RAILS_ENV'] == "development"
      worker = 1
    elsif ENV['RAILS_ENV'] == "staging" || ENV['RAILS_ENV'] == "testing"
      worker = 2
    else
      worker = 16
    end

    worker_processes worker

If you see the code to define the Rails.env :

# File railties/lib/rails.rb, line 81
def env
  @_env ||= ActiveSupport::StringInquirer.new(ENV["RAILS_ENV"] || ENV["RACK_ENV"] || "development")
end

Return "development" if ENV["RAILS_ENV"] and ENV["RACK_ENV"] are blank.

So you must use the Rails.env in your script or change it.
