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"
Listen 127.0.0.1:80


LoadModule cache_module modules/mod_cache.so
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_scgi_module modules/mod_proxy_scgi.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule rewrite_module modules/mod_rewrite.so
