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

    报的错误:

    In Connection.php line 664:
    
      SQLSTATE[HY000] [2054] 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 31:
    
      SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client
    
    
    In PDOConnection.php line 27:
    
      SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client
    
    
    In PDOConnection.php line 27:
    
      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:
