mod_deflate 是apache自带的模块,当然是在apache2后支持的,以前1的时候是mod_gzip,启用mod_deflate可以很好的为节省网页大小,只不过是占用服务器的资源和内存.用户看到页面的速度会大大加快.
提高网站速度除制作时减少冗余代码、进一步精简网页、CSS文件外，压缩输入也是一个不错的方法。deflate是apache自带的压缩模块，可以对动态输出内容或者静态内容（如HTML、JS、CSS等）进行压缩，减少网络传输量，从而提高响应速度，也提高了系统负载能力。
mod_filter过滤模块也扩展了功能，允许过滤器根据有条件的规定运行。这就改动了以前的旧模式。根据旧模式，只能根据AddOutputFilter指令的设置无条件地对文件实施过滤，或根据AddOutputFilterByType指令稍微灵活一点地对文件实施过滤。
安装 Apache时请注意 开启 mod_deflate, 我的就是忘了。

安装环境:
apache 的filters 源路径: /usr/local/src/httpd-2.4.23/modules/filters
apache 安装路径: /usr/local/apache
1. 安装 mod_deflate.so
[[email protected] ~]# cd /usr/local/src/httpd-2.4.23/modules/filters[[email protected] filters]# /usr/local/apache/bin/apxs -i -c -a mod_deflate.c
/usr/local/apr/build-1/libtool --silent --mode=compile gcc -std=gnu99 -prefer-pic -DLINUX -D_REENTRANT -D_GNU_SOURCE -g -O2 -pthread -I/usr/local/apache/include -I/usr/local/apr/include/apr-1 -I/usr/local/apr-util/include/apr-1 -c -o mod_deflate.lo mod_deflate.c && touch mod_deflate.slo
/usr/local/apr/build-1/libtool --silent --mode=link gcc -std=gnu99 -o mod_deflate.la -rpath /usr/local/apache/modules -module -avoid-version mod_deflate.lo
/usr/local/apache/build/instdso.sh SH_LIBTOOL='/usr/local/apr/build-1/libtool' mod_deflate.la /usr/local/apache/modules
/usr/local/apr/build-1/libtool --mode=install install mod_deflate.la /usr/local/apache/modules/
libtool: install: install .libs/mod_deflate.so /usr/local/apache/modules/mod_deflate.so
libtool: install: install .libs/mod_deflate.lai /usr/local/apache/modules/mod_deflate.la
libtool: install: install .libs/mod_deflate.a /usr/local/apache/modules/mod_deflate.a
libtool: install: chmod 644 /usr/local/apache/modules/mod_deflate.a
libtool: install: ranlib /usr/local/apache/modules/mod_deflate.a
libtool: finish: PATH="/usr/local/node/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/apache/bin:/usr/local/mysql/lib:/sbin" ldconfig -n /usr/local/apache/modules
----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/apache/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
chmod 755 /usr/local/apache/modules/mod_deflate.so
[activating module `deflate' in /etc/httpd/httpd.conf]
--------------------------------------------------------------------------------------------------
至此 mod_deflate.so 安装完成.
[[email protected] filters]# vim /etc/httpd/httpd.conf
(1. 去掉apache配置文件httpd.conf以下代码前的“#”
LoadModule deflate_module modules/mod_deflate.so
<IfModule mod_deflate.c>
SetOutputFilter DEFLATE
AddOutputFilterByType DEFLATE text/html text/css application/x-javascrip t application/json
</IfModule>
ECS, :wq 保存
重启apache,
[[email protected]]# apachectl restart
重新打开网页，查看：
