$redis global variable with ruby on rails

Question

I am using redis as a read cache. I have created an initializer

config/initializer/redis.rb

$redis = Redis.new(:host => ENV[\"REDIS_HOST\"], :port =&         


        

Answer 1

try this out:-

you can use constant instead of global variable.like in config/initializer/redis.rb

REDIS = Redis.new(:host => ENV["REDIS_HOST"], :port => ENV["REDIS_PORT"])

and in unicorn.rb

before_fork do |server, worker|
  # clear redis connection
  REDIS.quit if defined?(REDIS)
end

# Give each child process its own Redis connection

after_fork do |server, worker|
  REDIS ||= Redis.new(:host => ENV["REDIS_HOST"], :port => ENV["REDIS_PORT"])
end
