Mysql数据库常用操作

一、权限管理

1.创建库test
create  database test;

2.创建用户user01对库test有所有权限
grant all on test.* to 'user01'@'%'  identified by 'password'; 

3.创建用户并授与root相同授权权限。[grant 权限 on 数据库对象 to 用户]
grant all on *.* to 'user01'@'%' identified by '123456' with grant option;flush privileges;

4.只创建一个用户：
CREATE USER 'test'@'%'  IDENTIFIED BY '1234'; 

5.添加用户并授权：
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '12' WITH GRANT OPTION;

6.叠加权限，给user01用户所有库所有表增删改查的权限，只是select就是只有查询权限
grant select,insert,update,delete on *.* to 'user01'@'%' identified by 'password';

7.查看user01的权限
show grants for user01@%;

8.修改数据库密码：
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123');
update mysql.user set authentication_string=password(“123”) where User=”test” and Host=”localhost”;

9.撤销权限
首先查看该用户的权限，然后复制想要撤销的权限，将grant 改成revoke，将to 改为from 。
show grants for user01@%;
