mac下重置mysl8.0.11密码

mac下安装mysql8.0.11时 要求输入密码 之后想修改密码

• 注意 此方法适用于mac下的mysql8.0.11 其他版本不一定相同

1.启动mysql后正常登陆

2.查看sql中的root用户

select host, user, authentication_string, plugin from mysql.user;
+-----------+------------------+-------------------------------------------+-----------------------+
| host      | user             | authentication_string                     | plugin                |
+-----------+------------------+-------------------------------------------+-----------------------+
| localhost | mysql.infoschema | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password |
| localhost | mysql.session    | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password |
| localhost | mysql.sys        | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password |
| localhost | root             | *23AE809DDACAF96AF0FD78ED04B6A265E05AA257 | mysql_native_password |
+-----------+------------------+-------------------------------------------+-----------------------+
4 rows in set (0.00 sec)

3.重置密码

• 语法格式

  • select host, user, authentication_string, plugin from user;
  • plugin 密码加密方式
  • authentication_string 加密后的密码
• 注意 mysql8.0以后废弃了PASSWORD函数 添加密码的时候不需要使用函数

• 清空root密码

  • update user set authentication_string='你的密码' where mysql.user='root';

4.测试

• mysql -uroot -p你的密码
