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
