一个apache为两个不同端口的网站提供服务
看这篇博客前请先查阅? apache2.2.6 + mongrel_cluster1.0.5负载均衡?
一个台服务器开启两个httpd主进程，分别使用不同的配置文件，服务两个不同的网站。

两个配置文件中除了监听的端口、DocumentRoot和PidFile路径不同外其他地方均可相同（根据自己需求适当修改）。
分别使用以下命令启动或关闭：
/usr/local/apache2.2.22/bin/httpd? -f? /usr/local/apache2.2.22/conf/httpd2.conf -k start|stop|restart
/usr/local/apache2.2.22/bin/httpd -f /usr/local/apache2.2.22/conf/httpd.conf? -k start|stop|restart
另外：/usr/local/apache2.2.22/bin/httpd? -k restart 命令只会导致子进程（apache用户进程，如simon用户）重新启动，而主进程（root用户）是不会重新启动的。
