请教PHP建站，报错

本人为学生，大学毕业想给班级做的同学录，
下载了一个 艺琼同学网 的系统，安装之后，出现数据库连接错误现象，
具体代码如下：Warning: include(includelink.php) [function.include]: failed to open stream: No such file or directory in /home/nbpowerc/07-6.com/include/top.php on line 71

Warning: include(includelink.php) [function.include]: failed to open stream: No such file or directory in /home/nbpowerc/07-6.com/include/top.php on line 71

Warning: include() [function.include]: Failed opening 'includelink.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/nbpowerc/07-6.com/include/top.php on line 71
具体的情查看网站：www.07-6.com 求解。谢谢

好像安装的不是根目录 找不到包含文件

说的很明白，找不到文件，你去检查一下是否有这个文件，这个文件的目录是否正确。
