ssh隧道（跳板机）

通过ssh跳板机，连接远端mysql

本机：192.168.0.59
跳板机：121.212.2.22
mysql服务器：192.168.1.23（公网服务器的内网网卡IP，跟跳板机内网相连）

[root@localhost ~]# ssh -p 62222 -N -f -L 61001:192.168.1.231:3306  yuejianyuan@121.212.2.22

说明:
-p: yuejianyuan@121.212.2.22的ssh端口
-N: 不执行远程命令 (该参数在只打开转发端口时很有用)
-f: 一旦SSH完成认证并建立port forwarding，则转入后台运行
-L: 地址
最后接跳板机

[root@localhost ~]# mysql -h 127.0.0.1 -uusername -p -P61001
Enter password:
