今天下了个 MySQL8.0,发现Navicat连接不上,总是报错1251;
原因是MySQL8.0版本的加密方式和MySQL5.0的不一样,连接会报错。
试了很多种方法,终于找到一种可以实现的:
1. 先登陆 root 进入mysql 一般初始化无密码,回车登陆即可,有密码则输入密码
PS C:\Windows\system32> mysql -uroot -p
Enter password: ******

2.更改加密方式
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER; Query OK, 0 rows affected (0.10 sec)
3.更改密码:
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password'; Query OK, 0 rows affected (0.35 sec)
4.刷新:
mysql> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.28 sec)
