在HTTPD主配置文件中添加如下，并确保deflate模块是启用的
#vim /etc/httpd/conf/httpd.conf
SetOutputFilter DEFLATE//调用一个叫DEFLATE输出过滤器
# mod_deflate configuration
# Restrict compression to these MIME types
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE text/css
# Level of compression (Highest 9 - Lowest 1)
DeflateCompressionLevel 9//过滤时压缩比
# 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 \bMSI[E] !no-gzip !gzip-only-text/html
然后#service httpd reload
#cp /etc/rc.d/rc.sysinit /vhosts/web1/htdocs/test.html //vhosts/web1/htdocs这个目录是提前创建的
#curl -I http://192.160.108.160/test.html //查看响应报文的首部
#curl -I --compressed http://192.160.108.160/test.html
可以看出调用的压缩功能以后，响应报文首部的内容长度是原来的三分之一
