apache出问题，实在没办法求救！！！

2g00

suse10.1
apache+php+mysql一直正常

今天apache出问题出现403 Forbidden

我是执行过chmod 755 /就可以(如果／不是755以上就会出现403 Forbidden错误,我没动过，不晓得怎么回事)

http://127.0.0.1/index.php （index.php源码为phpinfo();）能正常显示。

当用phpmyadmin时(http://127.0.0.1/phpmyadmin/)
就出错了
Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0

Warning: Unknown: Failed opening '/usr/local/apache/htdocs/phpmyadmin/index.php' for inclusion (include_path='.:/usr/local/php/lib/php') in Unknown on line 0

apache日志如下:
[Mon Sep 11 23:51:05 2006] [notice] Apache/2.2.3 (Unix) PHP/5.1.6 configured -- resuming normal operations
[Mon Sep 11 23:55:50 2006] [error] [client 127.0.0.1] (13)Permission denied: access to /index.php denied
[Mon Sep 11 23:55:56 2006] [error] [client 127.0.0.1] (13)Permission denied: access to /phpmyadmin/ denied

真不明白/usr/local/apache/htdocs/权限是755,index.php这个文件执行就没问题（它也是要访问(include_path='.:/usr/local/php/lib/php'），phpmyadmin就不行，日志上说两个都说denied，照理说两个都不能正常访问，index.php就可以。
