用 upstart 脚本守护 sidekiq - 不工作

Question

我正在尝试使用 this 示例之后的两个新贵脚本来守护 sidekiq。 基本上，worker 服务会启动固定数量的 sidekiq 服务。

问题是 sidekiq 脚本在我启动 sidekiq 的代码行处失败。我试过直接在 bash 中运行命令，效果很好。

我尝试了所有不同的注释行，但没有一个有效。

所以我的问题是我做错了什么？我在哪里可以看到错误消息？

这是我修改后的 sidekiq 脚本：

# /etc/init/sidekiq.conf - Sidekiq config

# This example config should work with Ubuntu 12.04+.  It
# allows you to manage multiple Sidekiq instances with
# Upstart, Ubuntu's native service management tool.
#
# See workers.conf for how to manage all Sidekiq instances at once.
#
# Save this config as /etc/init/sidekiq.conf then mange sidekiq with:
#   sudo start sidekiq index=0
#   sudo stop sidekiq index=0
#   sudo status sidekiq index=0
#
# or use the service command:
#   sudo service sidekiq {start,stop,restart,status}
#

# TERM and USR1 are sent by sidekiqctl when stopping sidekiq.  Without declaring these    as normal exit codes, it just respawns.

你说得对，需要加载 RVM env。试试这个：

.....    
.....

script
exec /bin/bash <<EOT

  #export HOME=/home/deploy
  source /usr/local/rvm/environments/ruby-2.0.0-p353@global

  cd /home/rails
  exec sidekiq -i ${index} -e production

.....    
.....

有效吗？
