ruby-on-rails – Rails和Redis

redis-server

我像这样执行以下ruby脚本：

script/user/generate_roster_kids.rb start

但它不起作用,我得到：

generate_roster_kids] Pid not found,process seems doesn't exist!
[generate_roster_kids] Process daemonized with pid 1110 with thread and Forever v.0.3.2

如果我再次执行相同的命令,我得到以下内容：

generate_roster_kids] Found pid 1110...
[generate_roster_kids] Waiting the daemon's death . DONE
[generate_roster_kids] Process daemonized with pid 1385 with thread and Forever v.0.3.2

但它不起作用,我做错了什么.

这是generate_roster_kids.rb文件的内容：

#!/usr/bin/ruby
require 'rubygems' unless defined?(Gem)
require 'forever'
require 'redis'

Forever.run do
  REDIS = Redis.new()
  #
  # dir  "foo"     # Default: File.expand_path('../../',__FILE__)
  # file "bar"     # Default: __FILE__
  log  "bar.log" # Default: File.expand_path(dir,'/log/[file_name].log')
  # pid  "bar.pid" # Default: File.expand_path(dir,'/tmp/[file_name].pid')

  every 2.seconds do
    #REDIS.DEL :busy

    # begin
    #   REDIS.SUNIONSTORE :busy,REDIS.keys('Busy:*') 
    # rescue 
    #   REDIS.SUNIONSTORE :busy,nil
    # end

    REDIS.SUNIONSTORE :busy,REDIS.keys('Busy:*') rescue REDIS.SUNIONSTORE :busy,nil
    REDIS.EXPIRE :busy,3

    #online = REDIS.SUNION :online,REDIS.keys('Online:*')
    # diff = REDIS.SDIFF online,:busy

    #REDIS.SDIFFSTORE :online,(REDIS.SUNION :online,REDIS.keys('Online:*')),:busy
    #REDIS.DEL :online

    # begin
    #   REDIS.SUNIONSTORE :online,REDIS.keys('Online:*') 
    # rescue 
    #   REDIS.SUNIONSTORE :online,nil
    # end

    REDIS.SUNIONSTORE :online,REDIS.keys('Online:*') rescue REDIS.SUNIONSTORE :online,nil
    REDIS.EXPIRE :online,3
  end

end

这段代码是由较老的开发人员制作的,但他不再可用了,我需要在本地机器上完成这项工作.

提前致谢

UPDATE

我检查了我的redis-cli MONITOR,一切都“很棒”,但我有以下问题,当用户将状态更改为ONLINE时,我在MONITOR上看到了这个：

1400661418.908947 [0 127.0.0.1:57453] "DEL" "Busy:537c63ea20db9040d2000332"

如果用户改为BUSY,我看到了这个：

400661508.795043 [0 127.0.0.1:57453] "DEL" "Online:537c63ea20db9040d2000332"

但是当我使用redisdesktopmanager检查我的redis数据库时,我没有看到任何新记录,但是如果我尝试使用redis-cli手动创建记录,则记录成功创建,这可能是什么问题？ ???
