背景: zabbix 数据库迁移,搭建主从,主是5.6.25,从是5.7.15,流式备份应用 redo.log 之后,change master 和reset slave 时报出如下错误
mysql> CHANGE MASTER TO
-> MASTER_HOST=‘192.168.40.129‘,
-> MASTER_USER=‘repl‘,
-> MASTER_PASSWORD=‘repl_123‘,
-> MASTER_PORT=3306,
-> MASTER_LOG_FILE=‘mysql-bin.000005‘,
-> MASTER_LOG_POS=749,
-> MASTER_AUTO_POSITION=0;
ERROR 1794 (HY000): Slave is not configured or failed to initialize properly. You must at least set --server-id to enable either a master or a slave. Additional error messages can be found in the MySQL error log.
原因:从 5.6.25 版本使用 innobackupex 备份,在 5.7.15 版本中应用恢复,ibd系统表需要重建
解决步骤:
1、drop 备份的 ibd表
use mysql
drop table slave_master_info;
drop table slave_relay_log_info;
drop table slave_worker_info;
drop table innodb_index_stats;
drop table innodb_table_stats;
2、重建
mysql> source /usr/local/mysql/share/mysql_system_tables.sql
Query OK, 0 rows affected, 1 warning (0.00 sec)
3、重启数据库
[root@zero02 data]# /etc/init.d/mysqld restart
Shutting down MySQL.. [ OK ]
Starting MySQL.. [ OK ]
至此,问题解决,登陆数据库,重新 change master to 即可!
