mysql

UPDATE mysql.user SET Password=PASSWORD(‘yeqing‘),host=‘localhost‘ where USER=‘root‘;

pkill mysqld

pkill mysqld

mysql -u root -p

yeqing 进入

#3 先创建账号再授权（方法一）

create useryeqing@‘localhost‘ identified by ‘123456‘;

grant all ondb1.* to yeqing@‘localhost‘;

或者

grant select,insert,update,delete,create,dropon db1.* to ‘yeqing’@’192.168.1.%’ identified by ‘test123’

flushprivileges;

show grants foryeqing@‘localhost‘;
