web-services – docker nginx连接在连接到上游时被拒绝

[weixin_38061328]

我使用闪亮的服务器在端口3838上构建一个web-app,当我在我的服务器中使用nginx它运行良好.但当我在我的服务器上停止nginx并尝试使用docker nginx时,我发现该网站出现’502-Bad Gate Way’错误,nginx日志显示： 2016/04/28 18:51:15 [error] 8#8: *1 connect() failed (111: Connection refused) while connecting to upstream, ... 我通过这个命令安装docker-nginx： sudo docker pull nginx 我的docker命令行是这样的(为了清除我添加一些缩进)： sudo docker run --name docker-nginx -p 80:80 -v ~/docker-nginx/default.conf:/etc/nginx/conf.d/default.conf -v /usr/share/nginx/html:/usr/share/nginx/html nginx 我在我的家庭目录中创建了一个文件夹名称’docker-nginx’,将我的nginx conf文件移到此文件夹中,然后在etc / nginx目录中删除我原来的conf以防万一. 我的nginx conf文件如下所示： server { listen 80 default_server; # listen [::]:80 default_server ipv6only=on; root /usr/share/nginx/html; index index.html index.htm; # Make site accessible from http://localhost/ server_name localhost; location / { proxy_pass http://127.0.0.1:3838/; proxy_redirect http://127.0.0.1:3838/ $scheme://$host/; auth_basic "Username and Password are required"; auth_basic_user_file /etc/nginx/.htpasswd; # enhance the performance proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host $host; } }

您必须直接定义上游.目前,您的nginx无法代理您的Web应用程序. http://nginx.org/en/docs/http/ngx_http_upstream_module.html upstream backend { server backend1.example.com weight=5; server backend2.example.com:8080; server unix:/tmp/backend3; server backup1.example.com:8080 backup; server backup2.example.com:8080 backup; } server { location / { proxy_pass http://backend; } }
