用Navicat for mysql连接mysql报错1251-解决办法

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:\Windows\system32> mysql -uroot -p

再输入root的密码:

 
1
2
3
4
5
6
7
8
9
10
Enter password: ******

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:

mysql> use mysql;

| mysql.session    | localhost |
| mysql.sys        | localhost |
