mysql安装用户设置

mysql安装用户设置

xmapp安装后设置MariaDB问题

创建用户

insert into mysql.user(Host,User,Password) values("localhost","phplamp",password("1234"));

创建用户并分配所有权限

grant all privileges on dbname.* to 'username'@'%' identified by 'password';//

创建用户并分配权限

grant select,update on phplampDB.* to phplamp@localhost identified by '1234'; 

//修改用户密码

update mysql.user set password=password('新密码') where User="root" and Host="localhost";

删除用户指定权限

revoke insert,update,delete,select ON *.* from 'test'@'localhost' IDENTIFIED BY '123'; 

遇到的问题

• 设置一个用户无法链接，解决方法：

查询如果有，然后通过

select * from mysql.user where user='';

删除了多余的空白账户， 然后，通过

use mysql;
delete from user where user = '';

重载一次权限表,最后用

flush privileges;­

service mysqld restart
