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:
1PS C:\Windows\system32> mysql -uroot -p
再输入root的密码:
Enter password: ******

2.更改加密方式:
mysql> ALTERUSER'root'@'localhost'IDENTIFIED BY'password'PASSWORDEXPIRE NEVER;
Query OK, 0 rowsaffected (0.10 sec)
3.更改密码:该例子中 123为新密码
mysql> ALTERUSER'root'@'localhost'IDENTIFIED WITHmysql_native_password BY'123';
Query OK, 0 rowsaffected (0.35 sec)
4.刷新:
mysql> FLUSH PRIVILEGES;
Query OK, 0 rowsaffected (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;
Databasechanged
mysql> selectuser,host fromuser;
