刚装了mysql8.0，用navicat登陆不了,会出现2059错误,只能用命令行登陆

1.找到配置文件my.ini

将default_authentication_plugin=caching_sha2_password改为default_authentication_plugin=mysql_native_password

2.用命令行登陆

mysql -u root -p 

123456

3.use mysql

4.ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';

5.flush privileges;

6.可以用navicat登陆了
