11.25配置防盜鏈apache

• 經過限制referer來實現防盜鏈的功能vim

• 配置文件增長以下內容windows

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

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

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

        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" 自定義referer

配置防盜鏈

防盜鏈，就是不讓別人盜用你網站上的資源，這個資源，一般指的是圖片、視頻、歌曲、文檔等。

referer的概念

你經過A網站的一個頁面http://a.com/a.html 裏面的連接去訪問B網站的一個頁面http：//b.com/b.html ，那麼這個B網站頁面的referer就是http://a.com/a.html。 也就是說，一個referer其實就是一個網址。

1.配置防盜鏈

參考配置文件內容以下：

<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.測試網頁訪問：

//解釋說明：

首先定義容許訪問連接的referer，其中^$爲空referer，當直接在瀏覽器裏輸入圖片地址去訪問它時，它的referer就爲空。而後又使用filesmatch來定義須要保護的文件類型，訪問txt、doc、mp三、zip、rar、jpg、gif、png格式的文件，當訪問這樣的類型文件時就會被限制。

  • 在其它網站上連接這個網址，仍是打不開。

  • 而後在虛擬主機配置文件裏把第三方站點加入到白名單

在下面圖片上把第三方站點網址加入到白名單，而後保存退出從新加載配置。

[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 ~]# 

在點擊連接http://111.com/eagle1.jpg 訪問就能夠了，這就是referer，以下圖

3.直接複製網址http://111.com/eagle1.jpg 在瀏覽器打開是顯示Forbidden的。若想要直接能訪問的話，須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

測試語法錯誤並從新加載配置文件

[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 ~]# 

在瀏覽器中輸出網址http://111.com/eagle1.jpg ，是會直接顯示圖片的 

//這個就叫作空referer

4.使用curl進行測試

[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 ~]# 

也可使用-e來模擬referer，這個referer必定要以http://開頭，不然無論用。

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

11.26訪問控制Directory

• 核心配置文件內容

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

        Order deny,allow

        Deny from all

        Allow from 127.0.0.1

    </Directory>

• curl測試狀態碼爲403則被限制訪問了

訪問控制Directory

對於一些比較重要的網站內容,除了可使用用戶認證限制訪問以外,還能夠經過其餘一些方法作到限制,好比能夠限制IP,也能夠限制user_agent,限制IP指的是限制訪問網站的來源IP,而限制user_agent,一般用來限制惡意或者不正常的請求。

1.修改虛擬主機配置：

[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>
//解釋說明：

使用<Directory>來指定要限制訪問的目錄，order定義控制順序，哪一個在前面就先匹配哪一個規則(無論下面的規則先後順序)，在本例中deny在前面，因此要先匹配Deny from all,這樣全部的來源IP都會被限制，而後匹配Allow from 127.0.0.1,這樣又容許了127.0.0.1這個IP。最終的效果是，只容許來源IP爲127.0.0.1的訪問。

檢測配置文件是否有語法錯誤，並從新加載配置文件

//解釋說明

瀏覽器訪問提示Forbidden，其實就是403,再來看日誌，能夠查看到對應的來源IP爲192.168.11.136，但願不要把來源IP和本機IP搞混了，前面實驗中之因此本機IP和來源IP同樣，就是由於它至關於本身訪問本身，然後面用瀏覽器訪問，至關於拿windows訪問。

    <FilesMatch  "admin.php(.*)">

        Order deny,allow

        Deny from all

        Allow from 127.0.0.1

    </FilesMatch>

</Directory>

1.針對某個文件來作限制。

[root@tianqi-01 111.com]# 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>
        <FilesMatch  "admin.php(.*)">
        Order deny,allow
        Deny from all
        Allow from 127.0.0.1
        </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>

2.檢測與法並從新加載配置

[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.實驗配置結果

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

[root@tianqi-01 111.com]# 

//這個404意味着已經容許訪問了

//總結：

這個和Directory的功能是一致的，可是有時候咱們僅僅是想有時候針對一個訪問的連接去作控制，那你再去控制目錄就不合適了，咱們須要適當靈活一些，知足一些個性化的需求。
