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:

Enter password: ******
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 18

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
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:
