Nginx Thin.Sock找不到错误

3个文件簇（err.log，chat.yml，Nginx的chat.conf）：

err.log：

2015/03/19 15:05:50 [crit] 1535#0: *79 connect() to unix:/var/www/chat/public/tmp/sockets/thin.0.sock failed (2: No such file or directory) while connecting to upstream, client: 162.243.6.35, server: chat.stackin.money, request: "GET / HTTP/1.1", upstream: "http://unix:/var/www/chat/public/tmp/sockets/thin.0.sock:/", host: "chat.stackin.money" 2015/03/19 15:05:50 [crit] 1535#0: *79 connect() to unix:/var/www/chat/public/tmp/sockets/thin.1.sock failed (2: No such file or directory) while connecting to upstream, client: 162.243.6.35, server: chat.stackin.money, request: "GET / HTTP/1.1", upstream: "http://unix:/var/www/chat/public/tmp/sockets/thin.0.sock:/", host: "chat.stackin.money" 

chat.conf：

 upstream stackin_money { ip_hash; server unix:/var/www/chat/public/tmp/sockets/thin.0.sock max_fails=1 fail_timeout=15s; server unix:/var/www/chat/public/tmp/sockets/thin.1.sock max_fails=1 fail_timeout=15s; } server { listen 80; server_name chat.stackin.money; location / { proxy_pass http://stackin_money; proxy_set_header HOST $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } root /var/www/chat/public; # access_log /var/log/nginx/access.log; # error_log /var/log/nginx/error.log; } 

chat.yml：

• 如何在使用apache的托pipe网站的相同物理服务器上设置反向代理？
• 如何将multiplte node.js实例连接到单个域？
• 我怎样才能得到nginx反向代理与java小程序，检查文件库？
• 使用Apache反向代理和Postgresql调整Tomcat Java应用程序
• nginx和apache – 同一个IP上的多个虚拟主机 – 正确的configuration

 user: root group: root pid: tmp/pids/thin.pid timeout: 30 wait: 30 log: /var/log/thin/thin.log max_conns: 1024 require: [] environment: production max_persistent_conns: 512 servers: 2 onebyone: true threaded: true no-epoll: true daemonize: true socket: tmp/sockets/thin.sock chdir: /var/www/chat/public tag: chat aux 

所以我正在运行一个使用thin作为实时聊天的服务器的sinatra应用程序，因为我希望在一个子域上运行，我使用Nginx来反向代理。 然而，我遇到了一些Nginx或者Thin（Nginx的错误日志错误）的问题，它无法find我在Thin sockets的chat.yml中指定的文件或目录（下面）。 它是真的，它根本就没有。

任何帮助？ 提前致谢
