Question

我正在尝试在我的ubuntu服务器上持续部署一些rails微服务，我想也许runit是监督这些进程的好主意，然后使用chef中的迁移来更新微服务 - 但是我无法获得一项服务。基本上安装似乎在厨师部署中工作，但应用程序无法启动，并且没有在3000上监听（在部署文件夹中手动启动确实在杀死server.pid后工作）

这是一台干净配置的机器和盒子上唯一的rails应用程序 - 所以我认为日志中提到的错误是我试图启动它的症状。

关于这可能如何起作用的任何提示（替代方案）表示赞赏！

模板

#!/bin/bash
set -e
exec chpst -u root:root nohup rails server &

看起来不像nohup是这样做的 - 日志文件产生了这个。我不明白服务器是如何运行的 - 第一个日志条目表明它已经在运行......但是

2015-10-14_22:15:24.87117 A server is already running. Check     /opt/deploy/releases/39b30d7738bfba76462e257eb15100e1bea4edf0/tmp/pids/server.pid.

2015-10-14_22:15:25.32772 => Ctrl-C to shutdown server
2015-10-14_22:15:25.32773 Exiting

这会重复几次......直到此错误不再记录为止。

如果我ps aux | grep rails it很多这些条目
