编译安装Nginx
从1.9.0开始，nginx就支持对TCP的转发，而到了1.9.13时，UDP转发也支持了。提供此功能的模块为ngx_stream_core。不过Nginx默认没有开启此模块，所以需要手动安装
cd /usr/local/src wget http://nginx.org/download/nginx-1.12.1.tar.gz tar zxf nginx-1.12.1.tar.gz cd nginx-1.12.1 ./configure --prefix=/usr/local/nginx --with-stream make && make install
配置Nginx
TCP转发
目标：通过3000端口访问本机Mysql(其中mysql使用yum安装，默认配置文件)
/usr/local/nginx/conf/nginx.conf配置如下：
user nobody; worker_processes auto; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { use epoll; worker_connections 1024; } stream { server { listen 3000; proxy_pass 127.0.0.1:3306; 4# 也支持socket 4# proxy_pass unix:/var/lib/mysql/mysql.socket; } }
UDP转发
目标： 发送UDP数据到3000端口，3001端口可以接收
/usr/local/nginx/conf/nginx.conf配置如下：
user nobody; worker_processes auto; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { use epoll; worker_connections 1024; } stream { server { listen 3000 udp; proxy_pass 127.0.0.1:3001; } }
