1. source 端創建測試表
create table s select * from mysql.user ;
2. source 端查看測試表的建表語句
show create table s ;
<<EOF

3. source端創建用戶並且授權
GRANT ALL PRIVILEGES ON sources.s TO dex IDENTIFIED BY 'xiaojun';
GRANT ALL PRIVILEGES ON sources.s TO [email protected] IDENTIFIED BY 'xiaojun';
SHOW GRANTS FOR dex;
mysql> GRANT ALL PRIVILEGES ON sources.s TO dex IDENTIFIED BY 'xiaojun';
Query OK, 0 rows affected (0.03 sec)
mysql> GRANT ALL PRIVILEGES ON sources.s TO [email protected] IDENTIFIED BY 'xiaojun';
Query OK, 0 rows affected (0.00 sec)
mysql> SHOW GRANTS FOR dex;

4. 查看target端是否安裝了FEDERATED存儲引擎
mysql> 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 |
+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+
9 rows in set (0.00 sec)
看到沒有安裝federated存儲引擎(目標端可以是任何的存儲引擎比如說myisam或者innodb)
4.1 先來安裝federated存儲引擎
install plugin federated soname 'ha_federated.so';
mysql> install plugin federated soname 'ha_federated.so';
ERROR 1125 (HY000): Function 'federated' already exists
已經安裝好了,只是沒有啟用
測試一下是否可以
[root@rhel6Mysql02 ~]# mysqld_safe --federated &
[1] 2194
[root@rhel6Mysql02 ~]# 130620 18:12:28 mysqld_safe Logging to '/var/lib/mysql/rhel6Mysql02.err'.

好的修改一下my.c
