rvm 监控延迟作业

Question

我正在尝试使用 monit 运行delayed_job，但它无法运行，因为 rvm 的路径(每个用户的本地 rvm 安装)对该命令不可用。我的应用程序是一个带有 bundler 的rails2应用程序。 Monit 无法找到捆绑程序。有人对我如何了解 monit 的 rvm 路径有任何建议吗？

我收到错误

[rails@x-rws1 current]$ monit start delayed_job -c config/delayed_job.monitrc 
'delayed_job' start: /usr/bin/env
'delayed_job' failed to start
no such file to load -- bundler

我的config/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 script/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

“rvm -S”对我不起作用。

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

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引用文献，涉及与 RVM 作者关于 monit 的讨论:http://groups.google.com/group/rubyversionmanager/browse_thread/thread/d1a6c1f6396a8bf6/51afece4c8943912?#51afece4c8943912
