apache安装deflate

apache默认没有启用deflate,deflate是一个模块，需要安装，方法如下（源自[http://www.chinaz.com/server/2010/0308/108042.shtml）：][http_www.chinaz.com_server_2010_0308_108042.shtml]

首先查看apache是否加载了mod\_deflate.so模块，如果没有需要安装加载。找到并下载和当前apache版本相同的源码文件，解压缩到/home目录下，在apache安装目录下执行：

<table style="border-right:#0099cc 1px solid; table-layout:fixed; border-top:#0099cc 1px solid; border-left:#0099cc 1px solid; border-bottom:#0099cc 1px solid"> 
 <tbody> 
  <tr> 
   <td style="word-wrap:break-word">/usr/local/apache2/bin/apxs -i -c /home/httpd-2.0.63/modules/filters/mod_deflate.</td> 
  </tr> 
 </tbody> 
</table>

会自动在 httpd.conf添加

添加如下设置：

<table style="border-right:#0099cc 1px solid; table-layout:fixed; border-top:#0099cc 1px solid; border-left:#0099cc 1px solid; border-bottom:#0099cc 1px solid"> 
 <tbody> 
  <tr> 
   <td style="word-wrap:break-word">&lt;IfModule mod_deflate.c&gt; <br> &lt;Location /&gt; <br> #Insert filter <br> SetOutputFilter DEFLATE <br> # Netscape 4.x has some problems… <br> BrowserMatch ^Mozilla/4 gzip-only-text/html <br> # Netscape 4.06-4.08 have some more problems <br> BrowserMatch ^Mozilla/4\.0[678] no-gzip <br> # MSIE masquerades as Netscape, but it is fine <br> # BrowserMatch \bMSIE !no-gzip !gzip-only-text/html <br> # NOTE: Due to a bug in mod_setenvif up to Apache 2.0.59 <br> # the above regex won’t work.

  </tr> 
 </tbody> 
</table>

但是我在执行 **/usr/local/apache2/bin/apxs -i -c /home/httpd-2.0.63/modules/filters/mod\_deflate**时报错，说zlib.h找不到，需要安装zlib:

1.到[官网][Link 1]下载zlib，然后依次执行如下命令（针对64位系统）：

\#tar -zxvf zlib-1.2.3.tar.gz

\#CFLAGS=-fPIC ./configure --libdir=/usr/lib64

\#make

\#make install

再执行**/usr/local/apache2/bin/apxs -i -c /home/httpd-2.0.63/modules/filters/mod\_deflate**， 安装成功。

**然后重启apache,但是在 stop apache的时候报错如下：**

\[root@localhost bin\]\# ./apachectl stop  
Syntax error on line 274 of /usr/local/apache2/conf/httpd.conf:  
Cannot load /usr/local/apache2/modules/mod\_deflate.so into server: /usr/local/apache2/modules/mod\_deflate.so: undefined symbol: inflateEnd

**需要在 LoadModule deflate\_module modules/mod\_deflate.so 的前面加载zlib.so**

如下 ：

LoadFile /usr/lib/libz.so  
LoadModuledeflate\_module    modules/mod\_deflate.so

\[root@localhost bin\]\# ./apachectl stop

ok了。  
\[root@localhost bin\]\# ./apachectl start

再次刷新html页面，Response Headers里就多了一条：

**Content-Encoding **   gzip

至此，gzip启用成功~![大笑][laugh.gif]
