mysql8.0 Authentication plugin 'caching_sha2_password' cannot be loaded

Posted 2020-12-25 习惯沉淀

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:

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
