navicat连接mysql报错1251解决方案
今天使用 MySQL8.0,发现Navicat连接不上,总是报错1251;百度发现https://blog.****.net/xdmfc/article/details/80263215博客写的找到原因,然后连接成功了:
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:

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:9527
1
2
|
mysql> ALTER USER 'root' @ 'localhost' IDENTIFIED WITH mysql_native_password BY '9527' ;
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:

Navicat 连接MySQL的密码就是上面更改的新密码(如9527),也是MySQL的登录密码
