Navicat连接mysql8.0.1版本出现1251--Client does not support authentication protocol requested by server的解决

转载自:https://blog.csdn.net/XDMFC/article/details/80263215

好不容易安装好mysql,但又出现了mysql客户端版本太低的问题。根据参考的这篇博客,完美的解决了该问题。

1、通过命令行进入解压的mysql根目录下。

2、登陆数据库

mysql -uroot -p

3、再输入root的密码:

  1.   Enter password: ******
  2.   Welcome to the MySQL monitor. Commands end with ; or \g.
  3.   Your MySQL connection id is 18
  4.   Server version: 8.0.11 MySQL Community Server - GPL
  5.   Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.
  6.   Oracle is a registered trademark of Oracle Corporation and/or its
  7.   affiliates. Other names may be trademarks of their respective
  8.   owners.
  9.   Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
  10.   mysql>

4、更改加密方式:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;

5、更改密码:该例子中 123为新密码

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123';

6、刷新:

mysql> FLUSH PRIVILEGES;

这步完成后我已经成功解决了问题。如果报错,可以看下面第7步,博主依然给出了解决方案

7、

// 如果报错ERROR 1396 (HY000): Operation ALTER USER failed for 'root'@'%':

则是远程访问权限不正确,先选择数据库,查看一下再更改:

 
1 2 3 4 5 6 7 8 9 10 11 12 13 mysql> use mysql; Database changed   mysql> select user,host from user; +------------------+-----------+ user             | host      | +------------------+-----------+ | mysql.infoschema | localhost | | mysql.session    | localhost | | mysql.sys        | localhost | | root             | localhost | +------------------+-----------+ rows in set (0.00 sec)
