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（每个用户的本地rvm安装）不可用于该命令。我的应用程序是带有bundler的rails2应用程序。 Monit无法找到捆绑包。有没有人对如何判断monv的rvm路径有任何建议？

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

/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。

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

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作者讨论monit的讨论线程：http://groups.google.com/group/rubyversionmanager/browse_thread/thread/d1a6c1f6396a8bf6/51afece4c8943912?#51afece4c8943912

Answer 2

如果您已经与其他服务正常工作monit并且只需要为rvm环境添加delayed_job守护程序，您可以尝试使用此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"

此处rvm -S命令让脚本在当前的rvm ruby环境下运行

您可以尝试使用

启动守护程序

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

命令以及守护进程是否会启动（检查时将最后一个单词更改为“status”），而不是使用delayed_job.conf文件的好机会

并且不要忘记检查pid文件是否也在tmp/pids/文件夹中创建

rvm monit delayed_job
