nginx在DigitalOcean上返回“错误的网关-502”

Question

I am trying to configure nginx for a rails app on DigitalOcean. When I open my IP, I see the BAD GATEWAY (502) message.

In logs is

2014/06/03 09:58:57 [crit] 28612#0: *1 connect() to unix:/tmp/unicorn.myproject-staging.sock failed (2: No such file or directory) while connecting to upstream, client: 81.161.64.26, server: , request: "GET / HTTP/1.1", upstream: "http://unix:/tmp/unicorn.myproject-staging.sock:/500.html", host: "my_ip"

What does error message means and how could I fix it?

Thank you

EDIT:

The application is deployed here:

/home/deployer/apps/myproject-staging

请检查以确保您的Unicorn正在运行，并且unix套接字文件的路径正确。
