Client does not support authenti

笔者用navicate连接mysql8.0，然后连接的时候提示
"Client does not support authentication protocol requested by server; consider upgrading MySQL client"

解决方案如下:

C:\Program Files\MySQL\MySQL Server 8.0\bin>mysql -uroot -p
Enter password: ******
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 11
Server version: 8.0.12 MySQL Community Server - GPL

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> use mysql
Database changed
mysql> alter user 'root'@'localhost' identified with mysql_native_password by '1
23456';
Query OK, 0 rows affected (0.05 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

然后就可以连接成功了
