mysql dump 1449_跨版本mysqldump恢复报错Errno1449

已经有一套主从mysql,新增两个slave

主库Server version: 5.6.22-log MySQL Community Server (GPL)

旧从库Server version: 5.6.28-log MySQL Community Server (GPL)

新增SLAVE 1： Server version: 5.6.22-log MySQL Community Server (GPL)

新增SLAVE 2： Server version: 5.7.10-log MySQL Community Server (GPL)

重新初始化新的两个slave后，从就从库的mysqldump文件导入恢复，因为增加了--dump-slave参数，可以看到主库的位置。

CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.001196', MASTER_LOG_POS=71925475;

dump文件导入完成后，在新增SLAVE 1执行：

change master to master_host='192.168.72.142', master_user='repl',master_password='password',master_port=3306,MASTER_LOG_FILE='mysql-bin.001196', MASTER_LOG_POS=71925475,MASTER_CONNECT_RETRY=30;

用工具查看binlog日志内容，发现也出错了，网上查了一下，说是BUG

怀疑权限问题

主库5.6.22上执行

mysql> show grants for 'usr_pre'@'%';

+--------------------------------------------------------------------------------------------------------+

| Grants for usr_pre@% |

+--------------------------------------------------------------------------------------------------------+

| GRANT USAGE ON *.* TO 'usr_pre'@'%' IDENTIFIED BY PASSWORD '*EA8D6BC15C61128B3E5AB994B3EA12A9092114C5' |

| GRANT ALL PRIVILEGES ON `pre`.* TO 'usr_pre'@'%' |

+--------------------------------------------------------------------------------------------------------+

2 rows in set (0.02 sec)

旧SLAVE 5.6.28 备份导出的从库

mysql> show grants for 'usr_pre'@'%';

+--------------------------------------------------------------------------------------------------------+

| Grants for usr_pre@% |

+--------------------------------------------------------------------------------------------------------+

| GRANT USAGE ON *.* TO 'usr_pre'@'%' IDENTIFIED BY PASSWORD '*EA8D6BC15C61128B3E5AB994B3EA12A9092114C5' |

| GRANT ALL PRIVILEGES ON `pre`.* TO 'usr_pre'@'%' |

+--------------------------------------------------------------------------------------------------------+

2 rows in set (0.01 sec)

新SLAVE 1是5.6.22，执行报错

mysql> show grants for 'usr_pre'@'%';

ERROR 1141 (42000): There is no such grant defined for user 'usr_pre' on host '%'

在新SLAVE 1执行

mysql> GRANT USAGE ON *.* TO 'usr_pre'@'%' IDENTIFIED BY PASSWORD '*EA8D6BC15C61128B3E5AB994B3EA12A9092114C5' ;

Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON `pre`.* TO 'usr_pre'@'%';

ERROR 1133 (42000): Can't find any matching row in the user table

flush privileges;

show grants for 'usr_pre'@'%';

发现已经恢复正常

开启slave后，可以正常复制。

-----------------------

处理新增SLAVE 2:跨一个大版本，5.7.10

执行下面语句时报错：

mysql> change master to master_host='192.168.72.142', master_user='repl2',master_password='password',master_port=3306,MASTER_LOG_FILE='mysql-bin.001196', MASTER_LOG_POS=71925475,MASTER_CONNECT_RETRY=30;

ERROR 1805 (HY000): Column count of mysql.slave_master_info is wrong. Expected 25, found 23. The table is probably corrupted
