## 项目需求 ##

由于公司公网IP有限，现要通过反向代理把请求转发到内网，要支持HTTP/TCP等协议。接下来在nginx.conf添加如下配置

## HTTP反向代理 ##

http { 
            include       mime.types;
            default_type  application/octet-stream;
            #access_log  logs/access.log  main;
            sendfile        on;
            tcp_nodelay     on; #边接边传
            keepalive_timeout  65;
            gzip  on;
            autoindex on; #开启nginx目录浏览功能
            autoindex_exact_size off; #文件大小从KB开始显示
            autoindex_localtime on; #显示文件修改时间为服务器本地时间
            upstream backend { 
                    server 172.19.0.15:80;
            }
            server { 
                    listen       80;
                    server_name  localhost;
    				chunked_transfer_encoding on;
                    client_max_body_size  100000000m;
    
                    proxy_set_header  Host $http_host;
                    proxy_set_header  X-Real-IP  $remote_addr;
                    #proxy_set_header  REMOTE-HOST $remote_addr;
                    proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
                    proxy_read_timeout  1800;
    
                    location / { 
                            proxy_redirect off;
                            proxy_pass http://backend;
                    }
            }
    }

## TCP反向代理 ##

stream { 
        upstream backend { 
           # hash $remote_addr consistent;
            server 72.19.0.5:3306;
        }
    
        server { 
            listen 3306;
           # proxy_connect_timeout 1s;
           # proxy_timeout 3s;
            proxy_pass backend;
        }
    }

## docker stack部署 ##

### 编写yml ###

services:
      proxy:
        image: nginx:latest
        container_name: sg-proxy
        restart: always
        networks:
        - ng-net
        ports:
          - 80:80
          - 3307:3306
        volumes:
          - ng-log:/var/log/nginx
        deploy:
          mode: replicated
          replicas: 1
          restart_policy:
            condition: on-failure
          placement:
            constraints:
              - node.hostname == user
        configs:
          - source: nginx-conf
            target: /etc/nginx/nginx.conf
    
    configs:
      nginx-conf:
        file: ./nginx.conf
      my_other_config:
        external: true
    
    volumes:
      ng-log:
    
    networks:
      ng-net:
        external:
          name: sg-net

### docker stack启动 ###

docker stack deploy -c docker-compose.yml px
