MySQL5.6.26主从复制报错1050

一天老大要求做MySQL5.6的数据库的主从复制，，但是报错了，提示1050数据表已存在错误：
 Last_SQL_Errno: 1050
              Last_SQL_Error: Error 'Table 'authWeibo' already exists' on query. Default database: 'novel'. Query: 'CREATE TABLE `authWeibo` (
  `userId` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `unionId` varchar(100) DEFAULT NULL,
  PRIMARY KEY (`userId`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8mb4'

解决办法：
slave从库上停止从库复制线程，重置从库复制账户信息和同步失败的binlog文件以及同步失败的binglog位置点：
stop slave;
reset slave;
CHANGE MASTER TO  MASTER_HOST='192.168.10.98',MASTER_PORT=3306,MASTER_USER='novelrep',MASTER_PASSWORD='JuwoSdk21TbUser',master_log_file='mysql-bin.000073
',master_log_pos=1025057034;start slave;show slave status\G
到此同步成功
