mac下重置mysl8.0.11密码的方法

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)

语法格式

select host, user, authentication_string, plugin from user;

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
