mysql賬号和權限管理

#0 修改root密碼

mysqladmin -u root -p password yeqing

#1 删除無用賬号

select user,hostfrom mysql.user;

delete from mysql.user where user != 'root';

delete from mysql.user where user = 'root' and host='127.0.0.1';

flush privileges;

#2 誤删除root賬号怎麼辦?

/etc/init.d/mysqld stop 或者 pkill mysqld

mysqld_safe --user=mysql --skip-grant-tables --skip-networking &

mysql

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

pkill mysqld

mysql -u root -p

yeqing 進入

#3 先建立賬号再授權（方法一）

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

grant all on db1.* 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';

#4 建立賬号的同時授權（方法二）

grant all onmysql.* to yeqing@'localhost' identified by '123456';

grant all on  *.* to  test@’192.168.1.%’  identified by ‘test123’
