nginx & tengine实现四层代理

Nginx默认是通过stream进行代理的，配置模板如下:

server {
listen 8014;
proxy_pass cnes2101;
proxy_timeout 60s;
}

upstream cnes2101{
server 10.0.10.1:2101;
}

tengine是通过nginx_tcp_proxy_module三方模块实现的：

tcp {
upstream cluster {
# simple round-robin
server 192.168.0.1:80;
server 192.168.0.2:80;

check interval=3000 rise=2 fall=5 timeout=1000;

#check interval=3000 rise=2 fall=5 timeout=1000 type=ssl_hello;

#check interval=3000 rise=2 fall=5 timeout=1000 type=http;
#check_http_send "GET / HTTP/1.0\r\n\r\n";
#check_http_expect_alive http_2xx http_3xx;
}

server {
listen 8888;
...
proxy_pass cluster;
}
}
