机房停电，mysql启动后发现从库报错误:
Last_IO_Error: Got fatal error 1236 from master when reading data from binary log:
'Client requested master to start replication from position > file size;
the first event 'binlog.000140' at 1009874186,
the last event read from '/home/mysql/binlog/binlog.000140' at 4,
the last byte read from '/home/mysql/binlog/binlog.000140' at 4.'
解决办法:
mysqlbinlog /home/mysql/binlog/binlog.000140>my.log
[root@dev-env-22 binlog]# tail -f my.log
'/*!*/;

发现end_log_pos 1009594134比报错的1009874186小很多
从end_log_pos 1009594134开始应用
stop slave;
change master to master_host='192.168.1.22',master_port=3306,master_user='repl',master_password='repl',master_log_file='binlog.000140',master_log_pos=1009594134;
start slave;
继续报错
继续报错:
