Linux端口转发-rinted工具部署、配置、使用

编者按：

 

    近期由于公司开启定制项目规划，对于每个项目都会开启一个测试服务器，实施方会用到测试服务器的ssh端口、mysql端口、web端口，为了节省资源（公网IP、服务器资源复用），基于rinted工具搭建一个端口转发的服务器。下面的流程图将更好的表达本文即将实现的功能！

 

1、源码安装rinted：

    下载和解压源码包：

cd /usr/local/src && wget https://boutell.com/rinetd/http/rinetd.tar.gz && tar xf rinetd.tar.gz && cd rinetd

 

    修改编译配置：

sed -i 's/65536/65535/g' rinetd.c# 修改端口范围，否则会报错

 

    编译安装：

mkdir -p /usr/man/man8 && make && make install

 

    编辑配置文件:/etc/rinetd.conf

#自定义mysql端口：3001/3100 #自定义ssh端口：2001/2500 #自定义web端口：801/899 #端口转发:[Source Address] [Source Port] [Destination Address] [Destination Port] 0.0.0.0 8080 10.124.162.114 8080 0.0.0.0 443 10.124.162.114 8080 0.0.0.0 3001 10.124.162.114 33080 #端口映射： bindaddress bindport connectaddress connectport logfile /var/log/rinetd.log

 

    启动与关闭：

#启动 /usr/sbin/rinetd -c /etc/rinetd.conf #关闭 pkill rinetd

 

   启动脚本：/home/shell/rinetd  使用方法：sh /home/shell/rinetd start|stop|restart|reload

#!/bin/bash # # Startup script for Rinetd - this script starts and stops the rinetd daemon # # chkconfig: - 85 15 # description: Rinetd is an HTTP(S) server, HTTP(S) reverse proxy and IMAP/POP3 proxy server # processname: rinetd # config: /etc/rinetd.conf # pidfile: /var/lock/subsys/rinetd # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up.
