我是一个将Rails部署到生产环境的完整菜鸟，并且看到Capistrano退出并出现以下错误：

问题似乎与Phusion Passenger的配置以及部署用户的权限有关，但我不确定如何继续。
提前感谢您的帮助。
更新：错误似乎是Passenger正在以root用户身份在/ tmp /中创建文件，但随后尝试清除/删除它们作为“部署”＃39;由乘客承担的用户因为部署了＆＃39;拥有environment.rb。
/ tmp / dirs看起来像：
4 drwxr-xr-x. 4 root root 4096 May 20 14:15 passenger.Jy8mOoq/
4 drwxr-xr-x. 4 root root 4096 May 5 07:14 passenger.jZAgQb1/
4 drwxr-xr-x. 4 root root 4096 May 7 07:13 passenger.M9fxTPM/
4 drwxr-xr-x. 4 root root 4096 May 6 13:12 passenger.RWBkftW/
我认为这不是乘客的问题;这似乎更有可能是我的部署＆＃39;用户的权限。我按照Capistrano说明here
设置了部署用户答案 0 :(得分：3)
我对Passenger没有经验，但是从你的回溯中看来，你的部署用户似乎无权访问/tmp/passenger.RWBkftW/。文件。
查看用户乘客的运行情况，例如
ps aux
命令在您的服务器上。
然后，您应该向部署用户授予乘客访问权限，或者通过运行乘客的用户部署应用程序。
答案 1 :(得分：3)
此处为乘客作者。就像斯坦尼斯拉夫所说的那样。但我猜乘客在遇到这样的问题时不应该因错误而中止。它只是试图清理陈旧的目录。我会做出改变，以确保它可以继续运作。
编辑：这已在commit c957e9e1171中实施。
