403 forbidden:you don't have permission to access /test.ht..

I have installed apache, and try to access a page through browser, but
got the error:
403 forbidden:you don't have permission to access /test.html on this
server
I have checked the possible fail reason but don't take effect:

[root@localhost ~]# chmod 755 /usr/local/apache2/www/
[root@localhost ~]# chmod 755 /usr/local/apache2/www/*

i've checked in conf.conf

DocumentRoot "/usr/local/apache2/www/"

<IfModule dir_module>
DirectoryIndex index.html index.php index.htm
</IfModule>
is there any other places where i may made a mistake? hope can give me
some suggestion thanx:)

in access_log
