请教怎么设置LAMP

[haoyihuan]

昨天刚刚装好linux，用新立得安装了LAMP，一切顺利，浏览器可以浏览127.0.0.1及localhost，当然也可以输入自己的IP。
然后在网上看了下设置自己的站点目录，默认的是在/var/www，但是这里路径对我来说不是很方便，所以想把它改到/home/xxx下。但是改动以后，就不能用了，浏览器输入自己的IP提示：

Not Found
The requested URL / was not found on this server.
Apache/2.2.11 (Ubuntu) PHP/5.2.6-3ubuntu4.2 with Suhosin-Patch Server at 192.168.1.110 Port 80

请教各位大侠！

我在这个文件里面改了两个“/var/www”，把这个路径改为了/home/xxx（自己的路径） 之后就没有用了

打开的时候不知道在哪看到了提示 找不到DocumentRoot /home/xxx
