使用Nginx转发tcp请求

要求nginx版本大于1.9，
在nginx.conf添加如下，要求和http{}同级

stream {
    upstream cakehouse {
        server 172.17.210.101:10001 weight=5 max_fails=2 fail_timeout=30s ;
    }
    server {
        listen 8888;
        proxy_connect_timeout 10s;
        proxy_timeout 5s;
        proxy_pass cakehouse;
    }
}
