我正在尝试从旧电脑MySQL的奴隶移动到新的。 原始的从机是MySQL版本5.6.12，和新的从机一样（MySQL是2.4的一部分）。 旧机器的复制工作正常。 但是，当我停止奴隶，将数据文件夹和my.ini复制到新的，并尝试启动wamp我得到：

然后我连接到数据库，运行查询“SHOW SLAVE STATUS”：
Slave_IO_STATE:Connecting to master LAST_IO_ERRNO:2003 Last_IO_ERROR:error connecting to master '[email protected]:3306' - retry-time: 60 retries: 5
防火墙closures，master ip可用（ping工作）。 我想知道什么是错误的 – 正常的wamp启动服务失败，没有错误号，mysqld-debug无法连接到主。
当从站在原始虚拟机上运行没有任何问题时会出现什么错误？ 感谢所有的答案。
你是否更新了授权，以允许新的奴隶连接？
尽pipe日志没有提到它，MySQL错过了errmsg.sys文件。 这是在Windows事件查看器中提到的。 复制errmsg.sys后，一切正常，奴隶正确运行。
