mysql设置账号密码及授权

mysql数据库安装完成

1、设置root账号密码

alter user \'root\'@\'localhost\' identified by "123456";

update mysql.user set authentication_string=password(\'123456\') where user=\'root\' and Host = \'localhost\';

2、MySQL创建数据库：

CREATE DATABASE xm_user CHARACTER SET utf8 COLLATE utf8_general_ci;

CREATE DATABASE xm_order CHARACTER SET utf8 COLLATE utf8_general_ci;

3、给数据库授权

grant all on xm_order.* to \'user\'@\'%\' identified by "u123456";

grant all on xm_user.* to \'user\'@\'%\' identified by "u123456";
