MySQL主从报错解决:Table ‘mysql.gtid_slave_pos’ doesn’t exist

给内部一个数据库做异地热备,热备部分采用了 MariaDB 的 galera 集群模式。然后挑选其中一台作为 Slave 和深圳主集群做主从同步。

主集群是老环境,用的版本还是是 MySQL 5.5.13。用常规办法创建主从同步

MariaDB [(none)]>change master to master_host='192.168.1.100',master_user='rpl',master_password='rpl@201809',master_log_file='mysql-bin.001091',MASTER_LOG_POS=137962110,master_connect_retry=30;
MariaDB [(none)]>start slave;

结果有如下报错:

MariaDB [(none)]> show slave status\G

错误信息为:Last_SQL_Error: Unable to load replication GTID slave state from mysql.gtid_slave_pos: Table 'mysql.gtid_slave_pos' doesn't exist

搜了下资料,大部分说是没有执行 mysql_upgrade 导致的,不过我们这边的 MariaDB 是 Docker 跑的,而且用了很长时间了,理论上应该是没问题的才对。

既然提示没有这个表:Table 'mysql.gtid_slave_pos' doesn't exist,那我就创建一个吧!

从网上找到这个建表语句:

CREATE TABLE `gtid_slave_pos` (
       `domain_id` int(10) unsigned NOT NULL,
       `sub_id` bigint(20) unsigned NOT NULL,
       `server_id` int(10) unsigned NOT NULL,
       `seq_no` bigint(20) unsigned NOT NULL,
       PRIMARY KEY (`domain_id`,`sub_id`)
     ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COMMENT='Replication slave GTID state';

在作为 Slave 的 MariaDB 上执行,然后重启 slave 后问题解决,过程如下:

MariaDB [(none)]> show slave status\G
