rvm 监控延迟作业

Question

我正在尝试使用monit 运行delayed_job，但它无法作为rvm 的路径运行（基于每个用户的本地rvm 安装）对命令不可用。我的应用程序是带有捆绑程序的 rails2 应用程序。 Monit 无法找到捆绑程序。有人对我如何知道 rvm 的监控路径有什么建议吗？

我收到了错误

[rails@x-rws1 current]$ monit start delayed_job -c config/delayed_job.monitrc 
'delayed_job' start: /usr/bin/env
'delayed_job' failed to start

/home/rails/public_html/myapp/current/script/delayed_job:3

我的配置/delayed_job.monitrc

set daemon  120

check process delayed_job with pidfile /home/rails/public_html/myapp/shared/pids/delayed_job.pid
  start program = "/usr/bin/env RAILS_ENV=staging /home/rails/public_html/myapp/current/script/delayed_job start"
  stop program = "/usr/bin/env RAILS_ENV=staging /home/rails/public_html/myapp/current/script/delayed_job stop"

和脚本/delayed_job 可执行文件

#!/usr/bin/env ruby

require File.expand_path(File.join(File.dirname(__FILE__), '..', 'config', 'environment'))
require 'delayed/command'
Delayed::Command.new(ARGV).daemonize

如果你已经有与其他服务正常工作的monit，并且只需要为rvm环境添加delayed_job守护进程，你可以尝试使用这个conf文件（它适用于我）

/etc/monit/conf.d/delayed_job.conf（我有ubuntu服务器）

check process delayed_job with pidfile /{project_folder}/tmp/pids/delayed_job.pid
start program = "RAILS_ENV=production rvm -S /{project_folder}/script/delayed_job start"
stop program = "RAILS_ENV=production rvm -S /{project_folder}/script/delayed_job stop"

---

这里rvm -S命令让脚本在当前rvm ruby​​环境下运行

你可以尝试用

启动守护进程

$ RAILS_ENV=production rvm -S /{project_folder}/script/delayed_job start

命令以及守护进程是否会启动（通过将最后一个单词更改为“状态”来检查它）比使用延迟作业.conf 文件的机会大

别忘了检查tmp/pids/文件夹中是否也创建了pid文件

'rvm -S' 对我不起作用。

http://matthew.mceachen.us/blog/howto-make-system-wide-rvm-installations-work-with-cron-monit-delayed_job-and-passenger-1021.html 上的说明做了。

check process delayed_job.0
  with pidfile /u/apps/adgrok/shared/pids/delayed_job.0.pid
  start program = "/usr/local/bin/rvm-shell -c 'RAILS_ENV=production /u/apps/adgrok/current/script/delayed_job start -i 0'" as uid deploy and gid deploy
  stop program = "/usr/local/bin/rvm-shell -c 'RAILS_ENV=production /u/apps/adgrok/current/script/delayed_job stop -i 0'" as uid deploy and gid deploy
  if 2 restarts within 15 cycles then timeout

还有一个值得注意的参考与 RVM 的作者关于 monit 的讨论线程：http://groups.google.com/group/rubyversionmanager/browse_thread/thread/d1a6c1f6396a8bf6/51afece4c8943912?#51afece4c8943912
