我在生产网站上使用Resque.
当我部署时,我希望GOD停止所有工作者然后重新启动它们,因为有时我们会更改类的代码并重新排队失败的作业.
问题是,当我做上帝停止resque,耙子实际上没有停止,工人仍然活着并使用旧代码,这为我创造了各种各样的问题.
即使我做"上帝终止",它也不会杀死工人.
现在,我正在使用shell脚本来杀死工作者,但由于我有多个服务器,所以在所有生产服务器上进行操作时,这几乎是一件痛苦的事.
这是我的上帝配置文件:
rails_env = ENV['RAILS_ENV'] || "production"
rails_root = ENV['RAILS_ROOT'] || "/mnt/data-store/html/gogobot/current"
num_workers = rails_env == 'production' ? 5 : 2
num_workers.times do |num|
God.watch do |w|
w.dir = "#{rails_root}"
w.name = "resque-#{num}"
w.group = "resque"
w.interval = 2.minutes
w.env = {"QUEUE"=>"duplicate_merging,facebook_wall_posts,generic,mailer,notifications,realtime,scoring_system,signup,social_graph_facebook,social_graph_foursquare,social_graph_twitter,user_info,user_score", "RAILS_ENV"=>rails_env, "PIDFILE" => "#{rails_root}/tmp/resque_#{w}.pid"}
w.pid_file = "#{rails_root}/tmp/resque_#{w}.pid"
w.start = "cd #{rails_root}/ && rake environment resque:work QUEUE=duplicate_merging,facebook_wall_posts,generic,mailer,notifications,realtime,scoring_system,signup,social_graph_facebook,social_graph_foursquare,social_graph_twitter,user_info,user_score RAILS_ENV=#{rails_env}"
w.log = "#{rails_root}/log/resque_god.log"
w.uid = 'root'
w.gid = 'root'
# restart if memory gets too high
w.transition(:up, …这是上帝的重启命令的描述：restart <task or group name>。内置的初始化脚本会先杀死，然后开始。是否真的没有内置的方法可以向所有手表发送重启命令，无论它们是否分组？
我正试图让上帝启动我的resque队列.但是,当我运行god load config/resque.god它返回The server is not available (or you do not have permissions to access it)
这是我的resque.god文件:
rails_env = ENV['RAILS_ENV'] || "production"
rails_root = ENV['RAILS_ROOT'] || "/Users/andrewlynch/sites/wellness/wellbot"
God.watch do |w|
w.name = "resque-worker"
w.group = "resque"
w.interval = 60.seconds
w.dir = "#{rails_root}"
w.start = "RAILS_ENV=development QUEUE=* rake resque:work"
w.start_grace = 30.seconds
end
我试图用上帝监视redis但是上帝试图重新启动它,即使它已经在运行.这是我的.god脚本(移植自http://blog.thomasmango.com/post/636319317/resque-in-production):
# Redis
%w{6379}.each do |port|
God.watch do |w|
w.name = "redis-server"
w.interval = 30.seconds
w.start = "/etc/init.d/redis-server start"
w.stop = "/etc/init.d/redis-server stop"
w.restart = "/etc/init.d/redis-server restart"
w.start_grace = 10.seconds
w.restart_grace = 10.seconds
w.start_if do |start|
start.condition(:process_running) do |c|
c.interval = 5.seconds
c.running = false
end
end
end
end
现在当我像这样开始上帝:
god -c /home/phlegx/workspace/projectx/config/god/config.god -D --log-level debug
我得到以下输出:
I [2011-04-28 18:32:10] INFO: Loading /home/phlegx/workspace/projectx/config/god/config.god
I [2011-04-28 18:32:10] INFO: Syslog enabled.
I [2011-04-28 18:32:10] INFO: Using pid file directory: /var/run/god …我目前正在研究Rails/Ruby项目的过程监控选项,并且非常像上帝.
但我真的找不到任何关于如何监控多个应用程序(例如在一台机器上运行的2个rails项目)与上帝.
据我所知,我只是设置了神(系统红宝石)并让每个项目添加自己的配置(可能在某种程度上在deploy-hook中).这也适用于运行不同ruby版本(rbenv,rvm)或bundler的项目,因为god ruby不必访问任何项目代码.
有没有人像这样使用它？还是有更好的方法？
我有一个像这样的Procfile:
web: bundle exec unicorn -c config/unicorn.rb -E production
god: god -c services.god
但是foreman start god没有开始...它只是这样说:
17:14:32 god.1 | started with pid 29506
17:14:32 god.1 | exited with code 0
17:14:32 system | sending SIGTERM to all processes
SIGTERM received
如果我跑god -c services.god,所有服务运行良好...
任何想法？
谢谢
