1、如果未安装Apache。编译时,加上–enable-deflate,例如:(仅针对Linux版,Windows版无须此步骤)
./configure –prefix=/usr/local/apache –enable-rewrite –enable-so –enable-deflate
2、如果已安装Apache。添加mod_deflate模块,例如:(仅针对Linux版,Windows版无须此步骤)
/usr/local/apache/bin/apxs -i -a -c /home/zhangyan/software/httpd-2.0.59/modules/filters/mod_deflate.c
注:/home/zhangyan/software/httpd-2.0.59/为Apache源码路径。
3、进行以上步骤后,会在httpd.conf中自动加入一行:(Windows版请将下行最前面的#号去掉)
LoadModule deflate_module modules/mod_deflate.so
4、编辑httpd.conf,增加:
Linux版:
<ifmodule mod_deflate.c>
DeflateCompressionLevel 9
SetOutputFilter DEFLATE
#DeflateFilterNote Input instream
#DeflateFilterNote Output outstream
#DeflateFilterNote Ratio ratio
#LogFormat ‘”%r” %{outstream}n/%{instream}n (%{ratio}n%%)’ deflate
#CustomLog logs/deflate_log.log deflate
</ifmodule>
Windows版:
<ifmodule deflate_module>
DeflateCompressionLevel 9
SetOutputFilter DEFLATE
#DeflateFilterNote Input instream
#DeflateFilterNote Output outstream
#DeflateFilterNote Ratio ratio
#LogFormat ‘”%r” %{outstream}n/%{instream}n (%{ratio}n%%)’ deflate
#CustomLog logs/deflate_log.log deflate
</ifmodule>
如果将#号去掉,可以在logs/deflate_log.log日志文件中看到文件压缩前后的字节数、压缩比,例如:
”GET /index.html HTTP/1.1″ 49373/276249 (17%)
压缩前的字节数为276249,压缩后的字节数为49373,压缩比为17%
5、详细配置见Apache官方网站:http://httpd.apache.org/docs/2.0/mod/mod_deflate.html
