直接修改
用管理员身份打开cmd,输入"mysql -u root -p [-h locahost -P 3306]"(中括号内是默认内容)回车输入root用户密码进入MySQL客户端,然后:
mysql> alter user root@localhost identified by ‘newpassword‘ password expire never;
mysql> alter user root@localhost identified with mysql_native_password by ‘newpassword‘;
mysql> flush privileges; # 刷新权限
其中,"newpassword"是root用户新密码。
此时,Navicat可以连接成功,问题解决!
