环境是wamp3，apache是2.4的，之前用wamp2.5的时候,documentroot指定为h：demo(主目录下没有index.php之类的)，每次打开localhost是一个所有项目的目录，这次更新完wamp3，发现打开localhost是not found，但是输入localhost/test/ 能打开项目（test下有index.php）说明documentroot什么的配置是对的，我查了下如何显示apache目录。
回答说http.conf中
Options Indexes FollowSymLinks
可我发现我是有这项的

<Directory "H:/Demo">
    #
    # 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.
    #
    # The Options directive is both complicated and important.  Please see
    # http://httpd.apache.org/docs/2.4/mod/core.html#options
    # for more information.
    #
    Options Indexes FollowSymLinks

    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   AllowOverride FileInfo AuthConfig Limit
    #
    AllowOverride all

    #
    # Controls who can get stuff from this server.
    #

#   onlineoffline tag - don't remove
    Require local
</Directory>
