ruby-on-rails – Puma和Nginx 502 Bad Gateway错误(Ubuntu Se

我需要部署我的rails应用程序,所以我从这里开始执行所有步骤,https://www.digitalocean.com/community/tutorials/how-to-deploy-a-rails-app-with-puma-and-nginx-on-ubuntu-14-04

但是教程结束时,我收到了这个错误 – > “502错误的网关”

编辑
现在出现错误消息 – > “我们很抱歉,但有些不对劲.”
但是Nginx错误输出是一样的,我检查puma错误消息,但它们只是在启动时和正常停止时记录.

app_directory / log下的Rails日志不会产生任何输出.
puma-manager – >我检查它是否正常工作
路径—>我已经检查了三次

Nginx error.log输出消息：

2016/05/18 14:22:21 [crit] 1099#0: *7 connect() to unix:/home/deploy   /hotel-automata/shared/sockets/puma.sock failed (2: No such file or directory) while connecting to upstream,client: 192.168.2.105,server: localhost,request: "GET /favicon.ico HTTP/1.1",upstream: "http://unix:/home/deploy/hotel-automata/shared/sockets/puma.sock:/500.html",host: "192.168.2.170"
