默认apache在当前目录下没有index.html入口就会显示目录。让目录暴露在外面是非常危险的事，如下操作禁止apache显示目录，希望文章对各位有帮助。

进入apache的配置文件 httpd.conf找到：

OptionsIndexes FollowSymLinks

修改为：

OptionsFollowSymLinks

其实就是将Indexes去掉，Indexes表示若当前目录没有index.html就会显示目录结构。

1. 禁止访问某些文件/目录
增加Files选项来控制，比如要不允许访问.inc 扩展名的文件，保护php类库：
<Files ~ ".inc$">
Order allow,deny
Deny from all
</Files>

禁止访问某些指定的目录：（可以用<DirectoryMatch>   来进行正则匹配）
<Directory ~ "^/var/www/(.+/)*[0-9]{3}">
Order allow,deny
Deny from all
</Directory>

通过文件匹配来进行禁止，比如禁止所有针对图片的访问：
<FilesMatch .(?i:gif|jpe?g|png)$>
Order allow,deny
Deny from all
</FilesMatch>

针对URL相对路径的禁止访问：
<Location /dir/>
Order allow,deny
Deny from all
</Location>

配置示例：

<Directory "E:/Program Files/ApacheSoftware Foundation/Apache2.2/htdocs">
#
# Possible values for the Options directive are"None", "All",
# or any combination of:
# Indexes Includes FollowSymLinksSymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that "MultiViews" must be named*explicitly* --- "Options All"
# doesn't give it to you.
#
# The Options directive is both complicated andimportant. Please see
#http://httpd.apache.org/docs/2.2/mod/core.html#options
# for more information.
# 就是这一行，只去掉indexes也可
#Options Indexes FollowSymLinks
Options FollowSymLinks
#
# AllowOverride controls what directives may beplaced in .htaccess files.
# It can be "All", "None",or any combination of the keywords:
# Options FileInfo AuthConfig Limit
#
AllowOverride None
#
# Controls who can get stuff from this server.
#
Order allow,deny
Allow from all
</Directory>
建议默认情况下，设置APACHE禁止用户浏览目录内容。
