linux忘记MySQL8密码解决方案

Posted 2021-05-29 友 点胡说八道

1.修改mysql的配置文件（默认为/etc/my.cnf）,在[mysqld]下添加一行

skip-grant-tables

2、保存配置文件后，重启MySQL服务

service mysqld restart

3、再次进入MySQL命令行，输入密码时直接回车，就会进入MySQL数据库了。

mysql -uroot -p

 4，改密码

ALTER USER \'root\'@\'%\' IDENTIFIED WITH mysql_native_password BY \'123\';

——————————————————————————————————————————————————————————————————

第4步报错

ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option

1.先执行

flush privileges;

2.再执行

ALTER USER \'root\'@\'%\' IDENTIFIED WITH mysql_native_password BY \'123\';

第4步报错

ERROR 1396 (HY000): Operation ALTER USER failed for \'root\'@\'localhost\'

看一下

ALTER USER \'root\'@\'%\' IDENTIFIED WITH mysql_native_password BY \'123\';

是否写成了

ALTER USER \'root\'@\'localhost\' IDENTIFIED WITH mysql_native_password BY \'123\';
