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的/ error.log中

解决方法
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
