例子 
授权db的所有权限给指定的账户
GRANT ALL ON db.* to 'user_name'@'localhost';

给指定的用户授予角色
GRANT 'role1','role2' to 'user_name'@'localhost','user_name2'@'localhost';

授权db数据库的查询权限给指定用户
GRANT SELECT ON db.* to 'user_name'@'localhost';

给用户授权所有数据库的权限
GRANT ALL ON *.* to 'user_name'@'localhost';
查看权限 
show privileges;
