nginx代理socket

nginx配置

stream {
    upstream socketGm{
        hash $remote_addr consistent;
        server 192.168.0.74:30194 weight=5 max_fails=3 fail_timeout=30s;
        #server 192.168.0.74:30194;    
    }
    
    upstream socketSocsp{
        hash $remote_addr consistent;
        server 192.168.0.74:30193 weight=5 max_fails=3 fail_timeout=30s;
        #server 192.168.0.74:30193;    
    }

    server{
        listen 6781;
        proxy_connect_timeout 1s; 
        proxy_timeout 3s;
        proxy_pass socketGm;
    }

    server{
        listen 6780;
        proxy_connect_timeout 1s;
        proxy_timeout 3s;
        proxy_pass socketSocsp;
    }
}

使用upstream 需要配置

./configure --with-stream
make & make install

遇到问题

1.用nginx做tcp代理，客户端shutdownoutput，导致无法接收消息？

用nginx的stream模块做tcp代理， 发现客户端只要调socket.shutdownoutput后，nginx会关闭连接终止代理。 客户端删掉socket.shutdownoutput()后nginx可以正常转发。

nginx负载策略

1. 默认轮询 least_conn 最少连接 ip_hash建立连接服务器处理 权重 weight=2
   upstream sampleapp {
   least_conn;
   server <<dns entry or IP Address(optional with port)>>;
   server <<another dns entry or IP Address(optional with port)>>;
   }
