###前提・実現したいこと
nginxを正しく設定してrailsアプリをunicorn経由で表示したいです。
###発生している問題・エラーメッセージ
【ブラウザ】
502 Bad Gateway
【エラーログ】
2017/02/07 00:52:16 [error] 7050#7050: *9 connect() to unix:/var/run/unicorn/unicorn.sock failed (111: Connection refused) while connecting to upstream, client: xxx.xxx.xxx.xxx, server: anime-report, request: "GET / HTTP/1.1", upstream: "http://unix:/var/run/unicorn/unicorn.sock:/", host: "xxx.xx.xxx.xx"
ポート番号がいけないのでしょうか。。。
###該当のソースコード
【config/unicorn.rb】
worker_processes 2 working_directory "/home/anime/app/anime-report" listen "/var/run/unicorn/unicorn.sock" pid "/var/run/unicorn/unicorn.pid" preload_app true
【/etc/nginx/nginx.conf】
user nginx; worker_processes 1; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf; }
【/etc/nginx/conf.d/sample.conf】

ご経験ある方、ご指摘お願いします。
