主库上查看log-bin.000567 文件 tail -100

[root@usserver1 mysql]# mysqlbinlog log-bin.000567 > /tmp/log-bin.000567.log
[root@usserver1 mysql]# tail -10 /tmp/log-bin.000567.log

log-bin.000567文件最后几行 发现最后偏移量是121521539，上面的121779515远大于这个121521539，也就是参数sync_binlog=1000导致的。

从库上执行

stop slave;
change master to master_log_file='log-bin.000567',master_log_pos=121521539;
start slave;
