Mysql基于gtid的主从复制错误：1062

说明：
环境
mysql-master：172.16.200.43
mysql-slave：172.16.200.44
系统：centos7
版本：MySQL5.6.35

一、基于GTID复制环境的搭建前提

主从环境的搭建和5.5没有什么区别，唯一需要注意的是：开启GTID需要启用这三个参数：

#GTID
gtid_mode = on
enforce_gtid_consistency = 1
log_slave_updates   = 1

gtid-mode用来设置是否开启GTID功能，如果要开启GTID功能，需要同时开启log-bin和log_slave_updates功能，另外还需要开启enforce_gtid_consistency功能。gtid_mode参数可以设置为on、off、upgrade_step_1、upgrade_step_2四种值，其中upgrade_step_1和upgrade_step_2是给将来mysql可能的新功能预留的，对当前的myql没有任何意义。同时，mysql建议在mysql_upgrade的时候，关闭gtid_mode功能和enforce_gtid_consistency功能，因为Mysql在upgrade期间可能会操作非事务的MyISAM存储引擎表，会引起报错。

二、配置步骤

1、43上面授权44从库的账号

MySQL [(none)]> grant replication slave on *.* to  'slave'@'172.16.200.44' identified by '000000';
MySQL [(none)]> flush privileges;

2、配置主从同步

MySQL [(none)]> stop slave;
MySQL [(none)]> CHANGE MASTER TO MASTER_HOST='172.16.200.43', MASTER_USER='slave', MASTER_PASSWORD='000000', MASTER_AUTO_POSITION=1;
MySQL [(none)]> start slave;

3、关闭防火墙

systemctl stop firewalld.service   #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动

三、测试跳过一个事务

1、 43上面新建库test

2、43上面新建表info_area

CREATE TABLE `info_area` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT COMMENT '地区ID',
  `name` varchar(20) NOT NULL DEFAULT '' COMMENT '名称',
  `rel_id` varchar(50) NOT NULL DEFAULT '' COMMENT '关系ID',
  `pid` int(10) unsigned NOT NULL DEFAULT '0' COMMENT '父ID',
  `level` int(11) NOT NULL DEFAULT '0' COMMENT '类别，1、省份 2、市 3、区 4、县',
  PRIMARY KEY (`id`),
  UNIQUE KEY `UNQ_RID` (`rel_id`) USING BTREE,
  KEY `IDX_PID` (`rel_id`)
) ENGINE=InnoDB AUTO_INCREMENT=55185 DEFAULT CHARSET=utf8 COMMENT='地区表';

3、43插入3条语句,44完全同步

INSERT INTO `test`.`info_area` (`id`, `name`, `rel_id`, `pid`, `level`) VALUES ('10000', '北京', '10000', '10000', '1');
INSERT INTO `test`.`info_area` (`id`, `name`, `rel_id`, `pid`, `level`) VALUES ('10002', '三环以内', '100001000110002', '10001', '3');
INSERT INTO `test`.`info_area` (`id`, `name`, `rel_id`, `pid`, `level`) VALUES ('10003', '三环到四环之间', '100001000110003', '10001', '3');

4、 43删除id=10001

delete from info_area where id=10001;

5、44上面插入10001

INSERT INTO `test`.`info_area` (`id`, `name`, `rel_id`, `pid`, `level`) VALUES ('10001', '朝阳区', '1000010001', '10000', '2');

6、43上面插入10001

INSERT INTO `test`.`info_area` (`id`, `name`, `rel_id`, `pid`, `level`) VALUES ('10001', '朝阳区', '1000010001', '10000', '2');

由于主从复制，44也会同步该条数据，但是44上面刚刚已经插入过id=10001，所以此时报错

7、解决gtid下1062错误

mysql> stop slave;
mysql> set GTID_NEXT='0f869100-71d1-11e7-be5e-000c29f2e72e:14';  
mysql> begin;
mysql> commit;
mysql> set GTID_NEXT='AUTOMATIC';
mysql> start slave;
注：
传统方式
mysql> stop slave;
mysql> SET GLOBAL SQL_SLAVE_SKIP_COUNTER = n;  
mysql> start slave;

8、恢复正常
