mysql自带客户端连接服务器,mysql命令行客户端如何通过ssh服务器连接数据库啊？...

ssh到跳板机然后用 mysql 连接

利用ssh开启一个隧道

我这里的MySQL服务器是192.168.41.83, 我要在192.168.41.72连接

首先在192.168.41.72执行命令开启隧道

[root@mysql-test-72 ~]# ssh -NPf -o StrictHostKeyChecking=no root@192.168.41.83 -L 3305:127.0.0.1:3306

root@192.168.41.83's password:

[root@mysql-test-72 ~]#

-f: 完成连接后转入后台运行

-N: 不执行远程命令

-o StrictHostKeyChecking=no: 不提示是否要选择yes

3305: 本地端口

127.0.0.1:3306: 远程机器端口

检查端口状态

[root@mysql-test-72 ~]# netstat -ntlp

Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp 0 0 192.168.41.72:9991 0.0.0.0:* LISTEN 20409/mmm_agentd-te

tcp 0 0 127.0.0.1:3305 0.0.0.0:* LISTEN 28339/ssh

...

发现已经开启3305端口，尝试连接

[root@mysql-test-72 ~]# mysql -umytest -p -P3305 -h127.0.0.1

Enter password:
