• 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

    MySQL [(none)]> show slave statusG

    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

    MySQL [(none)]> show slave statusG
