11.25配置防盗链

11.26访问控制Directory

11.27访问控制FilesMatch

11.25配置防盗链

• 通过限制referer来实现防盗链的功能

• 配置文件增加如下内容

  <Directory /data/wwwroot/www.123.com>

        SetEnvIfNoCase Referer "http://www.123.com" local_ref

        SetEnvIfNoCase Referer "http://123.com" local_ref

        SetEnvIfNoCase Referer "^$" local_ref

        <filesmatch "\.(txt|doc|mp3|zip|rar|jpg|gif)">

            Order Allow,Deny

            Allow from env=local_ref

        </filesmatch>

    </Directory>

• curl -e "http://www.aminglinux.com/123.html" 自定义referer

配置防盗链

防盗链，就是不让别人盗用你网站上的资源，这个资源，通常指的是图片、视频、歌曲、文档等。

referer的概念

你通过A网站的一个页面http://a.com/a.html 里面的链接去访问B网站的一个页面http：//b.com/b.html ，那么这个B网站页面的referer就是http://a.com/a.html。 也就是说，一个referer其实就是一个网址。

1.配置防盗链

参考配置文件内容如下：

<Directory /data/wwwroot/111.com>
        SetEnvIfNoCase Referer "http://111.com" local_ref
        SetEnvIfNoCase Referer "http://111.com" local_ref
        SetEnvIfNoCase Referer "^$" local_ref
        <filesmatch "\.(txt|doc|mp3|zip|rar|jpg|gif｜png)">
            Order Allow,Deny
            Allow from env=local_ref
        </filesmatch>
    </Directory>

[root@tianqi-01 ~]# vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf

<VirtualHost *:80>
    DocumentRoot "/data/wwwroot/111.com"
    ServerName 111.com
    ServerAlias www.example.com 2111.com.cn
   # <Directory /data/wwwroot/111.com>
   #<FilesMatch 123.php>
        #AllowOverride AuthConfig
        #AuthName "111.com user auth"
        #AuthType Basic
        #AuthUserFile /data/.htpasswd
        #require valid-user
    #</FilesMatch>

    </Directory>
    <Directory /data/wwwroot/111.com>
        SetEnvIfNoCase Referer "http://111.com" local_ref
        SetEnvIfNoCase Referer "http://aaa.com" local_ref
        #SetEnvIfNoCase Referer "^$" local_ref
        <FilesMatch "\.(txt|doc|mp3|zip|rar|jpg|gif｜png)">
            Order Allow,Deny
            Allow from env=local_ref
        </FilesMatch>
    </Directory>
    SetEnvIf Request_URI ".*\.gif$" img
    SetEnvIf Request_URI ".*\.jpg$" img
    SetEnvIf Request_URI ".*\.png$" img
    SetEnvIf Request_URI ".*\.bmp$" img
    SetEnvIf Request_URI ".*\.swf$" img
    SetEnvIf Request_URI ".*\.js$" img
    SetEnvIf Request_URI ".*\.css$" img
    CustomLog "|/usr/local/apache2.4/bin/rotatelogs -l logs/111.com-access_%Y%m%d.log 86400" combined env=!img
</VirtualHost>

[root@tianqi-01 ~]# /usr/local/apache2.4/bin/apachectl -t
Syntax OK
[root@tianqi-01 ~]# /usr/local/apache2.4/bin/apachectl graceful
[root@tianqi-01 ~]# 

2.测试网页访问：

//解释说明：

首先定义允许访问链接的referer，其中^$为空referer，当直接在浏览器里输入图片地址去访问它时，它的referer就为空。然后又使用filesmatch来定义需要保护的文件类型，访问txt、doc、mp3、zip、rar、jpg、gif、png格式的文件，当访问这样的类型文件时就会被限制。

  • 在其它网站上链接这个网址，还是打不开。

  • 然后在虚拟主机配置文件里把第三方站点加入到白名单

在下面图片上把第三方站点网址加入到白名单，然后保存退出重新加载配置。

[root@tianqi-01 ~]# vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf

<VirtualHost *:80>
    DocumentRoot "/data/wwwroot/111.com"
    ServerName 111.com
    ServerAlias www.example.com 2111.com.cn
   # <Directory /data/wwwroot/111.com>
   #<FilesMatch 123.php>
        #AllowOverride AuthConfig
        #AuthName "111.com user auth"
        #AuthType Basic
        #AuthUserFile /data/.htpasswd
        #require valid-user
    #</FilesMatch>

    </Directory>
    <Directory /data/wwwroot/111.com>
        SetEnvIfNoCase Referer "http://111.com" local_ref
        SetEnvIfNoCase Referer "http://ask.apelearn.com" local_ref
        #SetEnvIfNoCase Referer "^$" local_ref
        <FilesMatch "\.(txt|doc|mp3|zip|rar|jpg|gif｜png)">
            Order Allow,Deny
            Allow from env=local_ref
        </FilesMatch>
    </Directory>
    SetEnvIf Request_URI ".*\.gif$" img
    SetEnvIf Request_URI ".*\.jpg$" img
    SetEnvIf Request_URI ".*\.png$" img
    SetEnvIf Request_URI ".*\.bmp$" img
    SetEnvIf Request_URI ".*\.swf$" img
    SetEnvIf Request_URI ".*\.js$" img
    SetEnvIf Request_URI ".*\.css$" img
    CustomLog "|/usr/local/apache2.4/bin/rotatelogs -l logs/111.com-access_%Y%m%d.log 86400" combined env=!img
</VirtualHost>

[root@tianqi-01 ~]# /usr/local/apache2.4/bin/apachectl -t
Syntax OK
[root@tianqi-01 ~]# /usr/local/apache2.4/bin/apachectl graceful
[root@tianqi-01 ~]# 

在点击链接http://111.com/eagle1.jpg 访问就可以了，这就是referer，如下图

3.直接复制网址http://111.com/eagle1.jpg 在浏览器打开是显示Forbidden的。若想要直接能访问的话，需要把配置文件中的空referer的#去掉。

[root@tianqi-01 ~]# !vim
vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf

   SetEnvIfNoCase Referer "^$" local_ref前的#去掉

测试语法错误并重新加载配置文件

[root@tianqi-01 ~]# /usr/local/apache2.4/bin/apachectl -t
Syntax OK
[root@tianqi-01 ~]# /usr/local/apache2.4/bin/apachectl graceful
[root@tianqi-01 ~]# 

在浏览器中输出网址http://111.com/eagle1.jpg ，是会直接显示图片的 

//这个就叫做空referer

4.使用curl进行测试

[root@tianqi-01 ~]# curl -x127.0.0.1:80 111.com/eagle1.jpg -I
HTTP/1.1 200 OK
Date: Sun, 04 Mar 2018 08:34:15 GMT
Server: Apache/2.4.29 (Unix) PHP/7.1.6
Last-Modified: Sun, 04 Mar 2018 02:41:55 GMT
ETag: "7e3b-5668d270ae2c0"
Accept-Ranges: bytes
Content-Length: 32315
Content-Type: image/jpeg

[root@tianqi-01 ~]# 

也可以使用-e来模拟referer，这个referer一定要以http://开头，否则不管用。

[root@tianqi-01 ~]# curl -e "http://www.qq.com/123.txt" -x127.0.0.1:80 111.com/eagle1.jpg -I
HTTP/1.1 403 Forbidden

[root@tianqi-01 logs]# 

11.26访问控制Directory

• 核心配置文件内容

  <Directory /data/wwwroot/www.123.com/admin/>

        Order deny,allow

        Deny from all

        Allow from 127.0.0.1

    </Directory>

• curl测试状态码为403则被限制访问了

访问控制Directory

对于一些比较重要的网站内容,除了可以使用用户认证限制访问之外,还可以通过其他一些方法做到限制,比如可以限制IP,也可以限制user_agent,限制IP指的是限制访问网站的来源IP,而限制user_agent,通常用来限制恶意或者不正常的请求。

1.修改虚拟主机配置：

[root@tianqi-01 ~]# vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf

<VirtualHost *:80>
    DocumentRoot "/data/wwwroot/111.com"
    ServerName 111.com
    ServerAlias www.example.com 2111.com.cn
   # <Directory /data/wwwroot/111.com>
   #<FilesMatch 123.php>
        #AllowOverride AuthConfig
        #AuthName "111.com user auth"
        #AuthType Basic
        #AuthUserFile /data/.htpasswd
        #require valid-user
    #</FilesMatch>
    <Directory /data/wwwroot/111.com/admin/>
        Order deny,allow
        Deny from all
        Allow from 127.0.0.1
    </Directory>
    <Directory /data/wwwroot/111.com>
        SetEnvIfNoCase Referer "http://111.com" local_ref
        SetEnvIfNoCase Referer "http://ask.apelearn.com" local_ref
        SetEnvIfNoCase Referer "^$" local_ref
        <FilesMatch "\.(txt|doc|mp3|zip|rar|jpg|gif｜png)">
            Order Allow,Deny
            Allow from env=local_ref
        </FilesMatch>
    </Directory>
    SetEnvIf Request_URI ".*\.gif$" img
    SetEnvIf Request_URI ".*\.jpg$" img
    SetEnvIf Request_URI ".*\.png$" img
    SetEnvIf Request_URI ".*\.bmp$" img
    SetEnvIf Request_URI ".*\.swf$" img
    SetEnvIf Request_URI ".*\.js$" img
    SetEnvIf Request_URI ".*\.css$" img
    CustomLog "|/usr/local/apache2.4/bin/rotatelogs -l logs/111.com-access_%Y%m%d.log 86400" combined env=!img
</VirtualHost>
//解释说明：

使用<Directory>来指定要限制访问的目录，order定义控制顺序，哪个在前面就先匹配哪个规则(不管下面的规则前后顺序)，在本例中deny在前面，所以要先匹配Deny from all,这样所有的来源IP都会被限制，然后匹配Allow from 127.0.0.1,这样又允许了127.0.0.1这个IP。最终的效果是，只允许来源IP为127.0.0.1的访问。

检测配置文件是否有语法错误，并重新加载配置文件

[root@tianqi-01 111.com]# 

//解释说明

浏览器访问提示Forbidden，其实就是403,再来看日志，可以查看到对应的来源IP为192.168.11.136，希望不要把来源IP和本机IP搞混了，前面实验中之所以本机IP和来源IP一样，就是因为它相当于自己访问自己，而后面用浏览器访问，相当于拿windows访问。

11.27访问控制FilesMatch

2.检测与法并重新加载配置

[root@tianqi-01 111.com]# /usr/local/apache2.4/bin/apachectl -t
Syntax OK
[root@tianqi-01 111.com]# /usr/local/apache2.4/bin/apachectl graceful
[root@tianqi-01 111.com]# 

3.实验配置结果

[root@tianqi-01 111.com]# curl -x192.168.11.136:80 http://111.com/admin/adffffffsa -I
HTTP/1.1 404 Not Found

//这个404意味着已经允许访问了

//总结：

这个和Directory的功能是一致的，但是有时候我们仅仅是想有时候针对一个访问的链接去做控制，那你再去控制目录就不合适了，我们需要适当灵活一些，满足一些个性化的需求。
