关于Navicat连接MySQL8.0报1251错误
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。
解决方法
首先进到命令窗口 按步骤执行命令
1.先通过管理员身份命令行进入mysql的root账户:
PS C:\Windows\system32> mysql -uroot -p
再输入root的密码:
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(这里写你root的密码)’;
Query OK, 0 rows affected (0.35 sec)
4.刷新:
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.28 sec)
简单来说就是登陆MySQL的root执行下面三句
ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER; #修改加密规则
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password(你的root密码)'; #更新一下用户的密码
FLUSH PRIVILEGES; #刷新权限
// 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
