Navicat连接MySql8.0的各种问题及解决方法

navicat连接mysql8.0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，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 |
+------------------+-----------+
