ruby-on-rails – Rails 4 nginx unicorn ssl = 502 Bad Gateway

浏览器显示502 Bad Gateway – nginx.唯一的好消息是我的SSL https和绿色锁定正在显示.

Nginx日志错误如下

nginx的/ error.log中

*1 connect() failed (111: Connection refused) while connecting to upstream,client: xx.xxx.xx.xx,server: mysite.com,request: "GET / HTTP/1.1",upstream: "http://xxx.xxx.xx.xxx:80/maintenance.html",host: "mysite.com"

home / unicorn / log / unicorn.log(好像在等待nginx)：

如果您希望我发布任何其他文件,请告诉我.
提前感谢任何回复的人. 问题是Unicorn和Nginx不同意共享套接字.此外,在您发布的文件中,上游和proxy_pass不匹配.怎么样：

在服务器上下文中：

location @unicorn {
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header X-Forwarded-Proto https;
  proxy_set_header Host $http_host;
  proxy_redirect off;
  proxy_pass http://unicorn_server; # This name must match the upstream
}

在http上下文中：

upstream unicorn_server {
  server unix:/var/run/my_site/unicorn.sock;
}

在Unicorn配置文件(这里是/home/unicorn/unicorn.conf)中：

listen '/var/run/my_site/unicorn.sock',:backlog => 64

注意Unicorn侦听Nginx发布请求的套接字.
