独angular兽收到USR2时是否保留相同的PID？

所以，我一直在玩个人服务器上的独angular兽部署。 这背后有各种各样的原因 – 其中之一就是我并不是特别想编译我自己的nginx版本，以便获得伪造的乘客。 （我喜欢有包pipe理的东西。）

无论如何，独angular兽正在performance出一些奇怪的行为。 当您发送Unocorn USR2信号时，它应该通过将它的pid文件从unicorn.pid复制到unicorn.pid.oldbin来进行热交换。 我已经configuration了我的unicorn.rb文件，所以如果它在启动时发现了unicorn.pid.oldbin – 它会将旧进程拍成一个QUIT – 就像我应该这样做。

然而，这似乎并没有工作，因为没有一个PID正在改变。 所以，无论是麒麟是inheritance相同的PID – 或者什么是错误的。

以下是大师独angular兽进程的一大步。 我在阅读系统电话方面并不是很壮观 – 但我没有看到任何东西在这里跳出来。 有人可以看看，并告诉我我失踪了吗？ 谢谢！

• 应用得到了新闻，然后服务器被拥有。 我添加了8个服务器，仍然太慢
• 如何在ec2上运行ruby / unicorn / nginx / app的AB Benchmarks？
• Linode Debian + rvm + nginx + Unicorn杀死主引导或不启动独angular兽
• 独angular兽：分网站生成的链接断开
• 我如何启动unicorn_rails作为在我的Ubuntu 12.04机器上安装rvm的启动脚本？
