//登陆

mysql -u root -p

//新增用户

insert into mysql.user(Host,User,Password) values("%","liudongri",password("iminerldr"));

flush privileges;

//分配root权限

grant all on *.* to 'liudongri'@'%';

flush privileges;

//分配查询权限

grant select,insert,update,delete on *.* to 'liudongri'@'%';

flush privileges;

mysql 设置root密码用SET PASSWORD命令

mysql -u root

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');
