Web无法启动500服务器错误
我遵循安装resque的配置指导。 我遇到了（OpenURI :: HTTPError）。 我使用的是RVM 1.9.2-p180，rails 3.0.6和POW.'resque-web'未能以500服务器错误启动。 这里发生了什么？
重现问题：
redis-server启动redis $ VVERBOSE=1 QUEUE=file_serve rake environment resque:work启动一个worker RAILS_ENV=development resque-web config/initializers/resque.rb 配置/ resque.yml
development: localhost:6379
test: localhost:6379
staging: localhost:6379
fi: localhost:6379
初始化/ resque.rb：
rails_root = ENV['RAILS_ROOT'] || File.dirname(__FILE__) + '/../..'
rails_env = ENV['RAILS_ENV'] || 'development'
require 'resque'
# require 'yaml'
unless defined?($redis)
$redis = Redis.new($redis = Redis.new(:host => 'localhost', :port => 6379))
end
Resque.redis = $redis
终奌站：

初始化/ redis.rb
$redis = Redis.new(:host => 'localhost', :port => 6379)
终端：（$ redis的证明）
> $redis
#<Redis client v2.2.0 connected to redis://localhost:6379/0 (Redis v2.2.5)>
ruby-1.9.2-p180 :003 > $redis.set('pepper', 'bacon') #=> "OK"
ruby-1.9.2-p180 :004 > $redis.get('pepper') #=> "bacon"
你有：
$redis = Redis.new($redis = Redis.new(:host => 'localhost', :port => 6379))
试试只是：
$redis = Redis.new(:host => 'localhost', :port => 6379)
