与Tigase不同，Openfire安装后，它的配置属性不是写入XML文件中，而是基本上都存到数据库表里。
配置属性所在的数据表为ofProperty表
mysql> select * from ofProperty;

29 rows in set (0.00 sec)
可见，domain域的配置见xmpp.domain这一行。
修改它的值即可。
mysql> update ofProperty set propValue='XXX.com' where;
但是要注意，要让修改后的domain域生效，需要重启Openfire服务器。
# cd /opt/openfire/
# ./bin/openfire restart
Shutting down openfire
Stopped.
Restarting openfire
此时可以用XMPP客户端进行验证，OK！
