一、 Apache多站点配置方法
1、打开Apache安装目录下conf/httpd.conf文件，找到下面两行文字,把最前面的 # 号去掉,然后保存。
#LoadModule vhost_alias_module modules/mod_vhost_alias.so
#Include conf/extra/httpd-vhosts.conf
2、接着找到同一文件中的DocumentRoot和Directory,改为站点目录的上一级目录
例如站点放在 C:/XAMPP/Appserv/Web/htdocs/,则改为以下形式
A、DocumentRoot "C:/XAMPP/Appserv/Web";
B、<Directory "C:/XAMPP/Appserv/Web">;
后续各个应用可部署在此目录下。
3、上述配置完成后即可打开Apache安装目录下/conf/extra/httpd-vhosts.conf文件，在最后添加如下：
<VirtualHost *:3333>
DocumentRoot "C:/xampp/Appserv/Webhtdocs"
ServerName localhost:3333
ErrorLog "logs/localhost3333-error.log"
</VirtualHost>
<VirtualHost *:3334>
DocumentRoot "C:/xampp/Appserv/Webmall"
ServerName localhost:3334
ErrorLog "logs/Slocalhost3334-error.log"
</VirtualHost>
至此，多站点配置工作完毕。
我在配置完后，由于上述第3步的配置有问题，导致Apache服务无法启动，在Apache的Log及Windows的日志内都无法找到具体的具体的错误信息提示。
以下是我用Xampp启动Apache时的错误：

上述错误，在度娘提供的帮助中，大都是说端口被占用，其实并不准确，最简单的办法，就是直接在CMD命令框内执行httpd.exe，此时命令框会提示具体的出错原因：
按上述提示直接解决。
