我正在尝试将 MySQL 从机从旧 PC 移到新 PC。原始从机是 MySQL 版本 5.6.12，与新从机相同（MySQL 是 wamp 2.4 的一部分）。复制在旧机器上工作正常。但是当我停止从机、将数据文件夹和 my.ini 复制到新机器并尝试启动 wamp 时，我得到：

就这些了。运行 mysqld-debug：
2015-12-20 17:26:01 2896 [Note] Plugin 'FEDERATED' is disabled.

2015-12-20 17:26:06 2896 [Note] Server socket created on IP: '::'.
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
防火墙已关闭，主 IP 可用（ping 有效）。我想知道，出了什么问题 - 常规 wamp 启动服务失败且没有错误号，mysqld-debug 无法连接到主服务器。
当从属设备在原始虚拟机上运行时没有任何问题，可能出了什么问题？ 感谢大家的回答。
答案1
您是否已更新授权以允许新的从属设备连接？
答案2
尽管日志中没有提到，但 MySQL 遗漏了 errmsg.sys 文件。Windows 事件查看器中提到了这一点。复制 errmsg.sys 后，一切正常，从属服务器正常运行。
