# 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**

\[root@aerchi.com ~\]\# cd /usr/local/src/httpd-2.4.23/modules/filters  
\[root@aerchi.com filters\]\# /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.

**2. 启用 mod\_deflate.so**

\[root@aerchi.com filters\]\#   vim /etc/httpd/httpd.conf

**(1. 去掉apache配置文件httpd.conf以下代码前的“\#”**

\#下行如没有，则添加  
LoadModule deflate\_module modules/mod\_deflate.so

LoadModule headers\_module modules/mod\_headers.so

LoadModule filter\_module modules/mod\_filter.so

注意：如果mod\_filter.so没有开启，apache将无法正常启动

**(2.添加到httpd.conf的文件尾**

<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,     
\[root@aerchi.com\]\#   apachectl restart  
  
重新打开网页，查看：
