Navicat连接MySQL8.0的正确方法(亲测有效)

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:

ps c:\windows\system32> mysql -uroot -p

再输入root的密码:

enter password: ******
welcome to the mysql monitor.  commands end with ; or \g.
your mysql connection id is 18
server version: 8.0.11 mysql community server - gpl
copyright (c) 2000, 2018, oracle and/or its affiliates. all rights reserved.

owners.
type 'help;' or '\h' for help. type '\c' to clear the current input statement.
mysql>

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';
query ok, 0 rows affected (0.35 sec)

4.刷新:

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;
database changed
mysql> select user,host from user;
+------------------+-----------+
| user             | host      |
+------------------+-----------+
| mysql.infoschema | localhost |
| mysql.session    | localhost |
| mysql.sys        | localhost |
| root             | localhost |
+------------------+-----------+
5 rows in set (0.00 sec)
