本机Apache的安装过程请见：
Apache的首页是由/usr/local/httpd/conf/httpd.conf文件的DocumentRoot决定的。
...
#
# 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 "/usr/local/apache2/htdocs"
<Directory "/usr/local/apache2/htdocs">
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that "MultiViews" must be named *explicitly* --- "Options All"
# doesn't give it to you.
...
让我们再去/usr/local/apache2/htdocs目录里看看。
[root@bogon conf]# cd /usr/local/apache2/htdocs
[root@bogon htdocs]#
[root@bogon htdocs]# ls
index.html
只有一个index.html显示出来，让我们把它修改下：
[root@bogon htdocs]# vi index.html
<html><title>Apache Title</title><body><h1>Congratulations!Apache works!</h1><br/><h2>2013-08-29</h2></body></html>
然后再访问下看看：
是预想的效果。可以了。
