报的错误：

In Connection.php line :

  SQLSTATE[HY000] [] The server requested authentication method unknown to the client (SQL: select * from information_schema.tables where table_schema = move and table_name = migrations and table_type = 'BASE TABLE')

In PDOConnection.php line :

  SQLSTATE[HY000] [] The server requested authentication method unknown to the client

In PDOConnection.php line :

  SQLSTATE[HY000] [] The server requested authentication method unknown to the client

In PDOConnection.php line :

  PDO::__construct(): The server requested authentication method unknown to the client [caching_sha2_password]

原因：

mysql8默认的使用密码认证方式不一样，mysql8.0默认使用caching_sha2_password，但是之前版本都是使用mysql_native_password

解决方案

修改caching_sha2_password为mysql_native_password

select user,host,plugin from mysql.user;

我这里执行了两句修改，修改root身份的“localhost”和“%”，代码如下：

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'root';

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';

执行成功：

巴特西

php7.3连接MySQL8.0报错 PDO::__construct(): The server requested authentication method unknown to the client [caching_sha2_password]
