centos上转发

yum install -y socat

ubuntu

apt-get update apt-get install -y socat

socat的使用

nginx tcp转发

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;
　　}
}

nginx udp 转发

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;
 }
}

windows 工具转发

netsh interface portproxy add v4tov4 listenaddress=172.16.0.4 listenport=8080 connectaddress=104.104.104.104 connectport=9999
