本文给大家分享的是查看MySQL连接的root密码的方法，下面话不多说来来看正文：
1.首先我们进到MySQL的bin目录下
|
1
|
➜ cd /usr/local/mysql/bin |
2.切换成root身份
|
1
|
➜ bin sudo su |
3.跨过权限的验证

4.以root身份登录MySQL

7.很明显我们需要的密码是存在user这个表下的，所以我们直接看user的表结构是怎么样的

8.表的内容比较多，但是我们很容易就发现，密码其实是存在authentication_string字段下的，那我们就可以直接读User内容为root的密码了

mysql> select authentication_string from user where User='root';+-------------------------------------------+| authentication_string |+-------------------------------------------+| *781D25322166DB7FF99BA4A1FA5ED30439A60DDE |+-------------------------------------------+1 row in set (0.01 sec) |
OK，那我们拿着这个密码到Navicat试试看
