搜索类似的问题，得到的答案类似于下面
mysql>SET PASSWORD FOR
'root'@'localhost' = OLD_PASSWORD('newpassword');
但是这些方法试了之后都是会提示语法的错误，如下：
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'odl_password('123456')' at line 1
为此东找西找，发现了一个适用的方法：
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '你的密码';
FLUSH PRIVILEGES;
这样之后 ，客户端就突然连接上了服务器
解锁用户
ALTER USER 'furrywall'@'localhost' ACCOUNT UNLOCK;
