MySQL 5.5.3 m3 主從同步不支援master-host問題的解決辦法

環境：
OS:CentOS release 5.5 (Final) (64位)
2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:14 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
Mysql:
mysql-5.5.3-m3.tar.gz
Master:192.168.0.100
Slave:192.168.0.200

大部分配置跟"MySQL主從同步、讀寫分離配置步驟、問題解決筆記[原創]"類似，但在從伺服器上配置的時候，加的複製條件都不能啟動資料庫；不過據網上訊息介紹，Mysql版本從5.1.7以後開始就不支援“master-host”類似的參數;
查看mysql_error.log中的報錯資訊如下；

無奈之下，從資料庫my.cnf修改為以下配置；（主要資料庫中注意ID為1，並加入要同步的庫既可）
