nginx 502 Bad Gateway after rails deploy

Question

I am deploying a rails app with nginx and unicorn and getting 502 bad getway.

Can someone help me solve this? Thank you very much

My Nginx error log (/var/log/nginx/error.log) shows:

 2015/05/14 00:26:22 [crit] 24642#0: *13 connect() to unix:/tmp/unicorn.easysign.sock failed (2: No such file or directory) while connecting to upstream, client: 89.100.32.54, server: localhost, request: "GET /easysign HTTP/1.1", upstream: "http://unix:/tmp/unicorn.easysign.sock:/500.html", host: "mysite.com"

/etc/nginx/conf.d/default.conf:

upstream app {
    # Path to Unicorn SOCK file, as defined previously
    server unix:/tmp/unicorn.easysign.sock fail_timeout=0;
}

server {
    listen 80;
    server_name localhost;

    root /var/www/mysite.com/public_html/easysign;

Please try to change path to the socket (for example) to "/var/www/sockets/unicorn.easysign.sock". Don't forget to create "/var/www/sockets" directory. Maybe there is an issue with privileges?
