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:
更改加密方式
1.先通过命令行进入mysql的root账户:
1
|
PS C:Windowssystem32> mysql -uroot -p |
再输入root的密码:

Enter password : ****** Welcome to the MySQL monitor. Commands end with ; or g.

2.更改加密方式:
1
2
|
mysql> ALTER USER 'root' @ 'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER; Query OK, 0 rows affected (0.10 sec) |
3.更改密码:该例子中 123为新密码
1
2
|
mysql> ALTER USER 'root' @ 'localhost' IDENTIFIED WITH mysql_native_password BY '123' ; Query OK, 0 rows affected (0.35 sec) |
4.刷新:
1
2
|
mysql> FLUSH PRIVILEGES ; Query OK, 0 rows affected (0.28 sec) |
// 如果报错ERROR 1396 (HY000): Operation ALTER USER failed for 'root'@'%':
则是远程访问权限不正确,先选择数据库,查看一下再更改:
