如何制作 Monit 运行 Sidekiq？

Question

我问这个问题，尽管我在技术上知道该怎么做。毕竟我已经在其他 3 台服务器上设置了这个环境。然而，它对这个全新安装的 RHEL6 非常非常顽固。

这是我的 /etc/monit.d/sidekiq_uploader.monitrc 文件中的一个条目：

# sidekiq worker 0
check process sidekiq_uploader_0
  with pidfile /var/run/sidekiq/uploader/sidekiq_0.pid
  start program = "/home/deploy/scripts/sidekiq uploader start production 0" with timeout 180 seconds
  stop program = "/home/deploy/scripts/sidekiq uploader stop production 0" with timeout 180 seconds
  group uploader_sidekiq

很简单，对吧？不起作用。创建 pid 文件，在 Rails 项目 log 目录中创建日志文件，然后什么都没有。

也许最令人沮丧的是，我可以将上面的启动和停止命令剪切并粘贴到命令行，并且它们运行完美.

在/var/monit/log中，一遍又一遍：

[EDT May 18 12:37:29] info     : Awakened by User defined signal 1
[EDT May 18 12:37:29] info     : 'sidekiq_uploader_0' start: /home/deploy/scripts/sidekiq
[EDT May 18 12:37:29] info     : 'sidekiq_uploader_0' start action done
[EDT May 18 12:37:59] error    : 'sidekiq_uploader_0' process is not running
[EDT May 18 12:37:59] info     : 'sidekiq_uploader_0' trying to restart

这是 Rails 日志中的唯一条目：

# Logfile created on 2016-05-18 12:37:21 -0400 by logger.rb/47272

至少没有帮助。当我在命令行运行启动命令时：

在 Rails /log 目录中创建日志，并创建 Rails production.log 文件。然后 sidekiq 日志文件包含：

# Logfile created on 2016-05-18 12:37:21 -0400 by logger.rb/47272

出于某种未知原因，我不得不将 Monit 配置文件中的命令更改为：

start program = "/bin/bash -c '/home/deploy/scripts/sidekiq uploader start production 0 &>/home/deploy/sidekiq_0.out'" with timeout 180 seconds
stop program = "/bin/bash -c '/home/deploy/scripts/sidekiq uploader stop production 0'" with timeout 180 seconds

我不知道为什么，但现在可以了。
