【问题描述】：

您好，我是这个项目的新手，在 CentOS7 ec2 实例上托管它时遇到问题。 我在访问我的域时收到此错误：

2017/02/17 05:53:35 [error] 27#27: *20 connect() failed (111: Connection refused) while connecting to upstream, client: xxx.xxx.xxx.xxx, server:myApp.io, request: "GET /favicon.ico HTTP/1.1", upstream: "http://172.18.0.7:5000/favicon.ico", host: "myApp.io", referrer: "https://myApp.io"

当我查看正在运行的容器时，我得到：

docker ps -a

我的 .env 文件具有正确的允许主机，即我的 ec2-instance ip 地址

知道我做错了什么吗？

【参考方案1】：

几个月前我遇到了同样的问题。请看一下这个答案： Problem with SELinux。它像魅力一样帮助了我:)

【讨论】：

谢谢，但我认为这与我遇到的问题不同。我尝试了解决方案，但没有奏效。我收到错误代码 111，该解决方案适用于错误代码 13。
