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
