Rails / Nginx / Capistrano / Puma:(111:Connection refused)连接上游

我不断收到这个错误在nginx.error.log中:

2016/06/06 20:14:02 [error] 907#0: *1 connect() to unix:///home/user/apps/appname/shared/tmp/sockets/appname-puma.sock failed (111: Connection refused) while connecting to upstream, client: 50.100.162.19, server: , request: "GET / HTTP/1.1", upstream: "http://unix:///home/user/apps/appname/shared/tmp/sockets/appname-puma.sock:/", host: "appname.com" (here it is with manually added newlines for your convenience) 2016/06/06 20:14:02 [error] 907#0: *1 connect() to unix:///home/user/apps/appname/shared/tmp/sockets/appname-puma.sock failed (111: Connection refused) while connecting to upstream, client: 50.100.162.19, server: , request: "GET / HTTP/1.1", upstream: "http://unix:///home/user/apps/appname/shared/tmp/sockets/appname- puma.sock:/", host: "appname.com" 

这是我的nginx.conf:

 upstream puma { server unix:///home/user/apps/appname/shared/tmp/sockets/appname-puma.sock; } server { listen 80 default_server deferred; # server_name example.com; root /home/user/apps/appname/current/public; access_log /home/user/apps/appname/current/log/nginx.access.log; error_log /home/user/apps/appname/current/log/nginx.error.log info; location ^~ /assets/ { gzip_static on; expires max; add_header Cache-Control public; } try_files $uri/index.html $uri @puma; location @puma { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://puma; } error_page 500 502 503 504 /500.html; client_max_body_size 10M; keepalive_timeout 10; } 

我究竟做错了什么? 我跟着数字海洋的教程build立了Capistrano,Nginx和Puma。

所以解决办法是重新启动美洲狮。

 cap production deploy:restart 

每当我重新启动服务器,我也需要重新启动美洲狮。

我的建议是检查

 ~/apps/appname/shared/log/puma.stderr.log 

日志文件。 你可能会找到答案
