尝试部署我的第一个应用程序(后端)。
但是我遇到了502 Bad Gateway类型的错误。
2016/05/03 14:46:14 [error] 2247#0: *19 connect() failed (111: Connection refused) while connecting to upstream, client: 172.31.43.183, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:5000/", host: "myHost.eu-west-1.elasticbeanstalk.com"

2016/05/03 14:55:04 [error] 2566#0: *61 connect() failed (111: Connection refused) while connecting to upstream, client: 172.31.43.183, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:5000/", host: "myHost.eu-west-1.elasticbeanstalk.com"
我将后端框架SparkJava用于端口4567上启动。
因此，我扩展了Nginx的配置(nginx/1.8.1)。但是问题始终存在。
server {
listen 4567 default_server;
listen [::]:4567 default_server ipv6only=on;
}

最佳答案
从您的日志中:upstream: "http://127.0.0.1:5000/"我看到，nginx试图连接到同一台计算机上的5000端口，并且拒绝连接。 5000端口上正在运行什么？您可能需要调查一下。
关于java - connect()失败(111 : Connection refused) while connecting to upstream. Java(SparkJava)Amazon Elastic，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/37012552/
