主的配置:
GRANT REPLICATION SLAVE ON *.* TO 'rep'@'%' IDENTIFIED BY '123456';
show master status;

从的配置如下：
change master to master_host='192.168.20.130',master_user='rep',master_password='123456',master_log_file='mysql-bin.000012',master_log_pos=107;

我flushlog也不行，重启了也不行。都是新装数据库。还有log_file,log_pos 都对，网络都通,授权账号也正确 。

Shell_HAT

Got fatal error 1236 from master when reading data from binary log: 'Could not find first log file name in binary log index file

看看 binary log index file 里面记录的二进制日志列表和操作系统里面真实的二进制日志列表是否一致
