篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Nginx + Docker Compose-连接到上游时connect()失败(111:连接被拒绝)相关的知识,希望对你有一定的参考价值。
感谢您抽出宝贵的时间阅读本文档。我正在尝试使用docker-compose将应用程序部署到AWS EC2实例。当我运行命令docker-compose up
并访问该站点时,我从nginx收到一条错误,提示以下错误。我了解nginx收到了请求,但无法找到与我的react应用程序的上游连接,希望对正确配置端口/设置提供任何帮助。
错误
2 connect() failed (111: Connection refused) while connecting to upstream, client: 108.212.77.70 server: example.com, request: "GET / HTTP/1.1", upstream: "http://172.29.0.4:8003/", host: "example.com"
这是我的Nginx默认配置

为什么存在这个问题有点令人尴尬,但是我能够解决这个问题。我做了我的Nginx容器中的ping frontend
,它已成功ping通前端容器。接下来,我做了curl -L http://frontend:8003
,并说了curl: (7) Failed to connect to frontend port 8003: Connection refused
。我去了前端容器并执行了netstat -tulpn
,它列出了3000作为暴露的端口。我检查了我的.env文件,它缺少port = 8003。之后,Nginx能够连接上游。
