数字海洋错误！连接上游时502坏网关（111：拒绝连接）

Question

所以我重置了我的数字海滴root密码，现在我在访问该网站时遇到502错误的网关错误。

以下是nginx_logs的快照：

2016/04/26 14:34:09 [error] 4019#0: *4 connect() to 
unix:/home/apane/redoakproject/tmp/sockets/puma.sock failed 
(111: Connection refused) while connecting to upstream, 
client: *.*.*.*.*, server: directrenos.com, request: 
"GET / HTTP/1.1", upstream: "http://unix:/home/apane/redoakproject/tmp/sockets/puma.sock:/", 
host: "directrenos.com"

如何让它重新启动并运行？

谢谢！
