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.c N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

以上编译完后,会在httpd.conf文件里追加以下两项:
LoadModule deflate_module modules/mod_deflate.so
LoadModule headers_module modules/mod_headers.so

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(蓝色部分)
[root@prfweb01 ~]# vi /usr/local/apache22/conf/extra/httpd-vhosts.conf
NameVirtualHost 192.168.10.21:80
<VirtualHost 192.168.10.21:80>

#   RewriteCond %{REMOTE_HOST} !^201.83.203.99
#   RewriteCond %{REMOTE_HOST} !^201.83.203.115
#   RewriteRule ^/(.*)$ http://min-yy.jp [R,L]

    ServerName min-yy.tv
    ErrorLog logs/min-yy.tv-error_log
    CustomLog "|/usr/local/apache22/bin/rotatelogs /usr/local/apache22/logs/min-yy.tv.%Y%m%d 86400 540" combined
    DocumentRoot /usr/local/apache22/htdocs/jhf_pente_web

DeflateCompressionLevel 9     ---> 指压缩程度的等级，从1到9，9是最高级别
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript   ---> 指定压缩类型
AddOutputFilter DEFLATE js css
DeflateFilterNote Input instream     ---> 声明输入流的byte数量
DeflateFilterNote Output outstream   ---> 声明输出流的byte数量
DeflateFilterNote Ratio ratio        ---> 声明压缩的百分比
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html
Header append Vary User-Agent env=!dont-vary

# Don't compress images
#SetEnvIfNoCase Request_URI \.(?:gif|jpg|cab|jpe?g|exe|bmp|mp3|rar|zip|swf|png)$ no-gzip dont-vary ---> jpg等已经压缩过的文件，就不需要再压缩了

LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%)' deflate ---> 声明日志类型
