Navicat连接MySQL8.0亲测

今天下了个 MySQL8.0，发现Navicat连接不上，总是报错1251；

试了很多种方法，终于找到一种可以实现的：

　　通过更改加密方式：

1.先通过命令行进入mysql的root账户

PS C:\Windows\system32> mysql -uroot -p
Enter password: ******

　　再输入root的密码后：

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 18

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.再更改密码：：

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'@'%'

　　则是你的远程访问权限不正确，通过

select user,host from user;

　　查看一下再更改，如下：

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)

　　##如果报错：

mysql> select user,host from user;
ERROR 1046 (3D000): No database selected

　　　　则先选择数据库再运行“  select user,host from user;  ”查看：

mysql> use mysql;
Database changed
