主人：

显示主人身份\ G; 授予复制奴隶在。到'beifen'@'％'由'123'标识;

On Slave：

将master更改为master_host ='192.168.2.92'，master_user ='beifen'，master_password ='123'，master_log_file ='binlog.000008'，master_log_pos = 107; 启动奴隶;

但是：显示奴隶状态\ G; 从二进制日志读取数据时，来自master的致命错误1236：'无法在二进制日志索引文件中找到第一个日志文件名'

我尝试重置slave，刷新slave上的日志，但问题仍然存在。如何解决它？

从二进制日志中读取数据时，来自master的致命错误1236：'无法在二进制日志索引文件中找到第一个日志文件名'
