You can use the following for a "it just works" approach to using REDIS in rails
First - install redis
brew install redis
Second - create the following. Note port can be anything you want but they should be unique. Redis by default runs on 6381 but, using that it risky, if some other app is using that you could get confusing results when keys overlap.
config/redis/development.conf
daemonize yes
port 6390
logfile ./log/redis_development.log
dbfilename ./db/development.rdb
and config/redis/test.conf
daemonize yes
port 6391
logfile ./log/redis_test.log
dbfilename ./db/test.rdb
Third - add this init script
config/init/redis_init.rb
require "redis"
rx = /port.(\d+)/
s = File.read("#{::Rails.root}/config/redis/#{::Rails.env}.conf")
port = rx.match(s)[1]
`redis-server #{::Rails.root}/config/redis/#{::Rails.env}.conf`
res = `ps aux | grep redis-server`
raise "Couldn't start redis" unless res.include?("redis-server") && res.include?("#{::Rails.root}/config/redis/#{::Rails.env}.conf")
REDIS = Redis.new(:port => port)
If you're deploying to Heroku and using redis-to-go use this script
config/init/redis_init.rb
require "redis"
if ::Rails.env == "production"
uri = URI.parse(ENV["REDISTOGO_URL"])
REDIS = Redis.new(:host => uri.host, :port => uri.port, :password => uri.password)
else
rx = /port.(\d+)/
s = File.read("#{::Rails.root}/config/redis/#{::Rails.env}.conf")
port = rx.match(s)[1]
`redis-server #{::Rails.root}/config/redis/#{::Rails.env}.conf`
res = `ps aux | grep redis-server`
raise "Couldn't start redis" unless res.include?("redis-server") && res.include?("#{::Rails.root}/config/redis/#{::Rails.env}.conf")
REDIS = Redis.new(:port => port)
end
Then - in your app just use the REDIS constant to deal with redis.... example:
REDIS.keys

Tag Sound Files With Easytag (Linux Mint 12)
This tutorial is supposed to show you how to change your sound
files' information like artist or title, also called tags, in a fast
way using Easytag. I am using Linux Mint 12 as an operating system, however the steps
should not differ greatly from other Ubuntu based distributions.
Easytag is only capable of tagging MP3, MP2, FLAC, Ogg Vorbis, MP4/AAC,
MusePack or Monkey's Audio files. Read more: |
