            set global validate_password_length=1;
4.创建外网访问的用户
    create user 'sjh'@'%' identified by '123456';
5.授予用户在本地服务器对该数据库的全部权限
    grant all privileges on dbname.* to sjh@localhost identified by '123456';
6.授予用户通过外网IP对于该数据库的全部权限
    grant all privileges on dbname.* to 'sjh'@'%' identified by '123456';
7.刷新权限
    flush privileges;
