**apache2**已经用mod\_deflate代替了mod\_**gzip**

**apache2**已经包含了mod\_deflate

打开模组  
httpd.conf添加  
LoadModule deflate\_module modules/mod\_deflate.so

如果想只压缩html,text,xml 如果下面配置:  
AddOutputFilterByType DEFLATE text/html text/plain text/xml

下面给出我的配置档: 
LoadModule deflate\_module modules/mod\_deflate.so 
 
<location /> 
SetOutputFilter DEFLATE 
 
BrowserMatch ^Mozilla/4 **gzip**\-only-text/html 
BrowserMatch ^Mozilla/4/.0\[678\] no-**gzip** 
BrowserMatch /bMSIE !no-**gzip** !**gzip**\-only-text/html 
 
\# Don't compress images 
SetEnvIfNoCase Request\_URI / 
/.(?:gif|jpe?g|png)$ no-**gzip** dont-vary 
SetEnvIfNoCase Request\_URI / 
/.(?:exe|t?gz|zip|bz2|sit|rar)$ no-**gzip** dont-vary 
SetEnvIfNoCase Request\_URI / 
/.pdf$ no-**gzip** dont-vary 
SetEnvIfNoCase Request\_URI / 
/.(css|js)$ no-**gzip** dont-vary 
 
\# Make sure proxies don't deliver the wrong content 
Header append Vary User-Agent env=!dont-vary 
 
</location>

DeflateFilterNote Input input\_info  
DeflateFilterNote Output output\_info  
DeflateFilterNote Ratio ratio\_info  
LogFormat '"%r" %\{output\_info\}n/%\{input\_info\}n (%\{ratio\_info\}n%%)' deflate  
CustomLog logs/deflate\_log.log deflate

在apache的使用手册上还有这么一句,但是不知道为什么不能添加上去.  
\# Make sure proxies don't deliver the wrong content  
Header append Vary User-Agent env=!dont-vary

这个可以压缩 SVN 出来的文件。

\---------------------------------------------

不能添加的原因是下面的模组没有打开：

LoadModule headers\_module modules/mod\_headers.so

=================

Apache deflate模块配置说明 
  前几天一直在找apache2.0以dso方式编译后加载deflate模块的办法 
试了apxs -ica mod\_deflate.cN次，始终是报 
Cannot load /opt/apache/modules/mod\_deflate.so into server: /opt/apache/modules/mod\_deflate.so: undefined symbol: deflate 
异常的痛苦，什么ldd mod\_deflate.so后再export LIB\_LIBRARY\_PATH呀，都试了N次，google也go了N天。终于在google上go出来一篇文章，终于解决，方法如下： 
vi /usr/local/apache2/bin/apr-config 
修改LDFLAGS=" " 为 LDFLAGS="-lz" 
然后再apxs -ica mod\_deflate.c 
就OK了 
 
另外在配置deflate规则时 
apache2.0推荐加上这句 
Header append Vary User-Agent env=!dont-vary 
以便确保不会输出在压缩过程中出现内容方面的error 
但一般情况下，在测试apache的语法过程中会现出 
Invalid command 'Header', perhaps mis-spelled or defined by a module not included in the server configuration 
解决办法就是加载一个headers模块就OK了 
 
不过最好还是在编译apache模块时直接加上--enable-deflate --enable-headers就省事多了。 
 
一、 需求 
压缩apache的输出内容，降低网站带宽 
二、 加载Apache的deflate模块 
1、 修改apr-config 
vi /usr/local/apache2/bin/apr-config 
修改LDFLAGS=" " 为 LDFLAGS="-lz" 
2、 到apache源安装目录下,例如 
cd /root/httpd-2.0.55/modules/filters 
3、加载mod\_deflate模块 
/usr/local/apache2/bin/apxs -i -a -c mod\_deflate.c 
如果没有安装headers模块，加载headers模块 
cd /root/httpd-2.0.55/modules/metadata 
加载mod\_headers模块 
/usr/local/apache2/bin/apxs -i -a –c mod\_headers.c 
三、配置Apache主配置文件 
1. 在httpd.conf主配置文件里添加如下行 
\#声明输入流的byte数量 
DeflateFilterNote Input instream 
\#声明输出流的byte数量 
DeflateFilterNote Output outstream 
\#声明压缩的百分比 
DeflateFilterNote Ratio ratio 
\#声明日志类型 
LogFormat '"%r" %\{outstream\}n/%\{instream\}n (%\{ratio\}n%%)' deflate 
CustomLog logs/deflate\_log deflate 
 
 
\#指定压缩参数 
<Location /> 
\# Insert filter 
SetOutputFilter DEFLATE 
 
\# Netscape 4.x has some problems... 
BrowserMatch ^Mozilla/4 gzip-only-text/html 
 
\# Netscape 4.06-4.08 have some more problems 
BrowserMatch ^Mozilla/4/.0\[678\] no-gzip 
 
\# MSIE masquerades as Netscape, but it is fine 
\# BrowserMatch /bMSIE !no-gzip !gzip-only-text/html 
 
\# NOTE: Due to a bug in mod\_setenvif up to Apache 2.0.48 
\# the above regex won't work. You can use the following 
\# workaround to get the desired effect: 
BrowserMatch /bMSI\[E\] !no-gzip !gzip-only-text/html 
 
\# Don't compress images 
SetEnvIfNoCase Request\_URI /.(?:gif|jpg|cab|jpe?g|exe|bmp|mp3|rar|zip|swf|png)$ no-gzip dont-vary 
 
 
\# Make sure proxies don't deliver the wrong content 
Header append Vary User-Agent env=!dont-vary 
</Location> 
二、日志输出格式如下 
\[root@trffic2 logs\]\# tail -f access\_log 
"GET /apache\_pb.gif HTTP/1.1" -/- (-%) 
"GET /manual/ HTTP/1.1" 2163/7434 (29%) 
"GET /manual/style/css/manual.css HTTP/1.1" 3973/18335 (21%) 
"GET /manual/style/css/manual-loose-100pc.css HTTP/1.1" 1006/2882 (34%) 
"GET /manual/style/css/manual-print.css HTTP/1.1" 2994/13017 (23%)

apache1.3.x可以用mod\_gzip进行优化网页浏览的速度，可以明显的感觉到速度的提升。在apache2中也尝试用mod\_gzip，但是配置后确发现网页不能正确显示（空白页），所以改换**mod\_deflate**。

在Linux命令行下运行以下命令安装**mod\_deflate**模块（斜体是apache2的目录）

/usr/local/apache2/bin/apxs -i -c */root/httpd-2.0.48*/modules/filters/**mod\_deflate**.c

编辑httpd.conf，加入以下内容：

LoadModule deflate\_module modules/**mod\_deflate**.so

DeflateFilterNote ratio  
  
LogFormat '"%v %h %l %u %t "%r" %>s %b "%\{Referer\}i" "%\{User-Agent\}i"" (%\{ratio\}n)' deflate

<Location /> 
 
\# Insert filter 
 
SetOutputFilter DEFLATE 
 
\# Netscape 4.x has some problems... 
 
BrowserMatch ^Mozilla/4 gzip-only-text/html 
 
\# Netscape 4.06-4.08 have some more problems 
 
BrowserMatch ^Mozilla/4.0\[678\] no-gzip 
 
\# MSIE masquerades as Netscape, but it is fine 
 
BrowserMatch MSIE !no-gzip !gzip-only-text/html 
 
\# Don't compress images 
 
SetEnvIfNoCase Request\_URI 
 
.(?:gif|jpe?g|png)$ no-gzip dont-vary 
 
 
 
\# Make sure proxies don't deliver the wrong content 
 
\# Header命令不对？注释这一行 
 
\# Header append Vary User-Agent env=!dont-vary 
 
</Location>

\#查找Customlog 注释原来的的一行，改成  
  
CustomLog logs/deflate\_log deflate

\#查看logs目录下deflate\_log文件，你可以看到许多这样的信息：
