解决Navicat for MySQL连接 Mysql 8.0.11 出现1251- Client does not support authentication protocol错误_第1张图片
Error提示

原因
mysql8 之前的版本中加密规则是mysql_native_password,而在mysql8之后,加密规则是caching_sha2_password。那么我们需要把mysql用户登录密码加密规则还原成mysql_native_password

解决方法

1).打开命令行小黑屏,进入MySQL的bin目录,然后输入mysql -u root -p,输入密码,如下所示:

C:\Users\v_xmmxhli>cd C:\Program Files\MySQL\MySQL Server 8.0\bin

C:\Program Files\MySQL\MySQL Server 8.0\bin>mysql -u root -p
Enter password: *****
Welcome to the MySQL monitor.  Commands end with ; or \g.

2).然后输入

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password'; #更新一下用户的密码
FLUSH PRIVILEGES; #刷新权限 

窗口给出的反应是:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'Mysql';
Query OK, 0 rows affected (0.20 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.05 sec)

3).再次在Navicat里验证一下,连接成功
