请教:apache中httpd.conf中DirectoryIndex 项

请教:apache中httpd.conf中DirectoryIndex 项

1.原来的默认是index.html,客户端浏览器可以访问,我现在换成别的网页,如abc.html,添加进去后,用浏览器访问,却说访问被拒绝。难道只能是index.html这个文件名吗?

2.安装php后,在DirectoryIndex中改为index.php ,客户端浏览器访问显示的错误是:
  Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0

Fatal error: Unknown: Failed opening required '/usr/local/webserver/apache2/htdocs/index.php' (include_path='.:/usr/local/lib/php') in Unknown on line 0

是缺什么文件吗?

大虾指点阿!
第一个问题,我看了一下错误日志,上面写的是
Permission denied:file permissions deny server access:
/usr/local/webserver/apache2/htdocs/abc.htm

难道权限还跟文件名有关吗?在httpd.conf里面怎么改啊?
权限位多少啊.是644么?
呵呵,解决了,是权限问题,该了以后就好了
谢谢!
