教你如何解决Navicat低版本连接MySQL8.0的数据库

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

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)
