1、查看target端是否安装了FEDERATED存储引擎

mysql> show engines ;
+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+
| Engine | Support | Comment | Transactions | XA | Savepoints |
+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+
| CSV | YES | CSV storage engine | NO | NO | NO |
| MRG_MYISAM | YES | Collection of identical MyISAM tables | NO | NO | NO |
| MyISAM | YES | MyISAM storage engine | NO | NO | NO |
| BLACKHOLE | YES | /dev/null storage engine (anything you write to it disappears) | NO | NO | NO |
| MEMORY | YES | Hash based, stored in memory, useful for temporary tables | NO | NO | NO |
| FEDERATED | NO | Federated MySQL storage engine | NULL | NULL | NULL |
| ARCHIVE | YES | Archive storage engine | NO | NO | NO |
| InnoDB | DEFAULT | Supports transactions, row-level locking, and foreign keys | YES | YES | YES |
| PERFORMANCE_SCHEMA | YES | Performance Schema | NO | NO | NO |
+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+

注意：如果没有安装FEDERATED 引擎执行install plugin federated soname 'ha_federated.so';

这里已经安装好了，只是没有启用

2、将federated添加到my.cnf 重启数据库
vi /etc/my.cnf
[mysqld]
federated

service mysql restart

mysql> show engines;
+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+
| Engine | Support | Comment| Transactions | XA| Savepoints |
+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+
| InnoDB | DEFAULT | Supports transactions, row-level locking, and foreign keys | YES | YES | YES|
| MRG_MYISAM | YES | Collection of identical MyISAM tables | NO| NO| NO |
| CSV| YES | CSV storage engine | NO| NO| NO |
| BLACKHOLE | YES | /dev/null storage engine (anything you write to it disappears) | NO| NO| NO |
| MyISAM | YES | MyISAM storage engine | NO| NO| NO |
| MEMORY | YES | Hash based, stored in memory, useful for temporary tables | NO| NO| NO |
| ARCHIVE| YES | Archive storage engine | NO| NO| NO |
| PERFORMANCE_SCHEMA | YES | Performance Schema | NO| NO| NO |
| FEDERATED | YES | Federated MySQL storage engine | NO| NO| NO |
+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+

这里FEDERATED引擎已经启用。
