问题

客户每分钟都会收到错误和(如果配置)一封电子邮件,报告 MySQL 复制出现问题。 

出现以下错误:
失败的原因和结果Replication of the repository failed on the database server 

如下所示:

Got fatal error 1236 from master when reading data from binary log: 'Client requested master to start replication from position > file size'

副本在日志的某个位置(其当前位置)请求数据,但主控的日志文件未达到该点(因此缺少条目)。由于这是逻辑错误,复制停止。
