mysql8.0 Authentication plugin 'caching_sha2_password' cannot be loaded

安装mysql8.0后使用navicat创建连接, 然后报如题所示警告.可参考如下解决方案:

https://stackoverflow.com/questions/49194719/authentication-plugin-caching-sha2-password-cannot-be-loaded

8.0改变了身份验证插件，改成使用老版本的身份验证插件方式就好了。

我的操作步骤:

1.修改C:\ProgramData\MySQL\MySQL Server 8.0\my.ini文件中,caching_sha2_password改为mysql_native_password

#default_authentication_plugin=caching_sha2_password
default_authentication_plugin=mysql_native_password

2.修改mysql密码, 重启mysql服务就ok了.

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: *********

mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED WITH mysql_native_password BY ‘newrootpassword‘;
Query OK, 0 rows affected (0.10 sec)

mysql> exit
