##执行如下语句发现还是报如上的错误
stop slave;
change master to master_host=‘192.168.1.22‘,master_port=3306,master_user=‘repl‘,master_password=‘repl‘,master_log_file=‘binlog.000081‘,master_log_pos=1023205366;
start slave;

##查看该pos之后的内容

从下一个日志开始
stop slave;
change master to master_host=‘192.168.1.22‘,master_port=3306,master_user=‘repl‘,master_password=‘repl‘,master_log_file=‘binlog.000082‘,master_log_pos=0;
start slave;

master_log_pos=0 ##系统会自动匹配pos位置

mysqlbinlog --no-defaults --start-position=1023205366 /home/mysql/binlog/binlog.000081
