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。

具体步骤：

1. 从源码安装apache服务，安装路径： /usr/local/apache2.2.22

在/usr/local/apache2.2.22/conf 下创建两个配置文件httpd.conf和httpd2.conf。

httpd.conf:

ServerRoot "/usr/local/apache2.2.22"

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。
