nginx在多层服务器代理接口地址的应用方式_MsSqlserver

场景

访问接口地址 --> a服务器 --> a服务器反向代理到b服务器 --> b服务器反向代理到c服务器 --> 获取结果并返回

1、a 服务器反向代理配置

server {
    listen 4832;
    server_name _;
    location / {
        proxy_pass http://192.168.25.6:4832/;
        proxy_set_header host $host;
        proxy_set_header x-real-ip $remote_addr;
        proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;
        proxy_http_version 1.1;
        proxy_set_header upgrade $http_upgrade;
        proxy_set_header connection "upgrade";
    }

    location /file/device/ {
        proxy_pass http://192.168.25.6:9500/energy/;
        proxy_set_header host $host;
        proxy_set_header x-real-ip $remote_addr;
        proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;
        proxy_set_header x-forwarded-proto $scheme;
    }

    #冷水机接口-鉴权
    location /dashboard-lsj-8888/ {
        proxy_pass http://192.168.25.6:8001/dashboard-lsj-8888/;
        proxy_set_header host $host;
        proxy_set_header x-real-ip $remote_addr;
        proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;
        proxy_set_header x-forwarded-proto $scheme;
    }

    #冷水机接口-数据
    location /dashboard-lsj-90/ {
        proxy_pass http://192.168.25.6:8001/dashboard-lsj-90/;
        proxy_set_header accesstoken $http_accesstoken;
        proxy_set_header host $host;
        proxy_set_header x-real-ip $remote_addr;
        proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;
        proxy_set_header x-forwarded-proto $scheme;
    }
}

2、b 服务器反向代理配置

location /dashboard-lsj-8888/ {
        proxy_connect_timeout 300s;
        proxy_read_timeout 1800s;
        proxy_send_timeout 600s;
        proxy_set_header   host             $http_host;
        proxy_set_header   x-real-ip        $remote_addr;
        proxy_set_header   x-forwarded-for  $proxy_add_x_forwarded_for;
        proxy_set_header   x-forwarded-proto  $scheme;
        proxy_pass http://192.168.53.171:8888/;
}


location /dashboard-lsj-90/ {
        proxy_connect_timeout 300s;
        proxy_read_timeout 1800s;
        proxy_send_timeout 600s;
        proxy_set_header   host             $http_host;
        proxy_set_header   x-real-ip        $remote_addr;
        proxy_set_header   x-forwarded-for  $proxy_add_x_forwarded_for;
        proxy_set_header   x-forwarded-proto  $scheme;
        proxy_set_header accesstoken $http_accesstoken;
        proxy_pass http://192.168.53.171:90/;
}
