增加用户并授权：

grant select,insert,update,delete on *.* to [email protected]"%" Identified by "aaa"; 

#增加一个用户test，密码为aaa，该用户可在任何主机上（%）登录，并对所有数据库（*.*所有库的所有表）有查询、插入、修改、删除的权限：

 

 

查看用户情况：

SELECT User, Host, Password FROM mysql.user;

 

查看某个用户权限：

show grants for ‘usertest‘;

 

添加用户：

create user usertest identified by ‘aaa’;

 

用户授权：

flush privileges;

 

修改用户密码：

update mysql.user set password = password(‘newpassword‘) where user = ‘usertest‘ and host = ‘%‘;

flush privileges;
