MySQL ERROR 1698 (28000) error

MySQL ERROR 1698 (28000) ....

sudo mysql -uroot goes in

update mysql.user set password=PASSWORD('root') where User='root';

Reboot after changing the password

root login prompt password error

Baidu

After mysql 5.7, if you forget your password and change your password, the password column is no longer Password, but authentication_string

Solution steps:

stop mysql service

~$ sudo service mysql stop

Start MySQL in Safe Mode

~$ sudo mysqld_safe --skip-grant-tables &

Here may prompt that mysqld_safe already exists

I can't turn it off with kill -9 but restart it

Start MySQL in safe mode after reboot

After MySQL starts, you can log in without a password

mysql -uroot

Modify the root password and plugin

update mysql.user set authentication_string=PASSWORD('newPwd'), plugin='mysql_native_password' where user='root';

restart the service

can log in successfully
