请问有关apache的配置文件?

lksj

启动httpd后,可以访问apache服务器,看到那个TestPage,我想知道这个文件是放在哪里的阿?httpd.conf里说,

#
# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
#
DocumentRoot "/var/www/html"
可是我找不到阿,里面是个叫usage的目录

lksj

我知道了,原来没有首页就是这个,我传了个首页就看不见testpage了,可是这一页是哪里来的呢?
