nginx 的四层代理
需要编译四层模块

[root@python nginx-1.15.9]# ./configure --prefix=/data/web --sbin-path=/usr/bin --user=nginx --group=nginx --with-http_stub_status_module --with-http_auth_request_module --with-http_sub_module --add-module=/root/nginx-http-concat --with-http_addition_module --with-http_secure_link_module --with-http_geoip_module --with-http_ssl_module --add-module=/root/ngx_cache_purge --with-http_slice_module --with-http_v2_module --with-stream
[root@python nginx-1.15.9]# make

四层反代里
上游
server {

server_name "";
listen 9001 proxy_protocol; 只处理proxy_protocol请求
location /{
return 200 'hjjjuuyuu\n';
}
四层代理
server {
listen 4453;
proxy_pass 127.0.0.1:9001;
proxy_protocol on; 添加proxy_protocol协议头部
}

udp反向代理
server {
listen 4436 udp;
proxy_pass 127.0.0.1:9999;
proxy_requests 1;
proxy_responses 2;
proxy_timeout 2s;
