安装mod_expires
mod_expires模块添加是启用对有效期控制,也可以加里面,有效控制带宽成本
- #cd /usr/local/src/httpd-2.2.17/modules/metadata
- #apxs -c -i -a mod_expires.c
输出
- [root@web-02 metadata]# apxs -c -i -a mod_expires.c

- 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_expires.so
在httpd.conf里添加即可
- ExpiresActive on
- ExpiresDefault "access plus 14 month"
- ExpiresByType text/html "access plus 14 months"
- ExpiresByType text/css "access plus 14 months"
- ExpiresByType image/gif "access plus 14 months"
- ExpiresByType image/jpeg "access plus 14 months"
- ExpiresByType image/jpg "access plus 14 months"
- ExpiresByType image/png "access plus 14 months"
- EXpiresByType application/x-javascript "access plus 14 months"

mod_deflate 模块提供了DEFLATE 输出过滤器,允许服务器在将输出内容发送到客户端以前进行压缩,以节约带宽。
安装过程
- #/usr/local/src/httpd-2.2.17/modules/filters
- #apxs -i -c -a mod_deflate.c
输出
- [root@WEB-02 filters]# apxs -c -i -a mod_deflate.c

验证:

正确安装后,修改httpd.conf添加下面的内容即可
- <IfModule mod_deflate.c>
- DeflateCompressionLevel 9
- AddOutputFilterByType DEFLATE text/plain application/x-httpd-php
- AddOutputFilter DEFLATE php css js
- </IfModule>
PS:
apxs参数
- -i 此选项表示需要执行安装操作,以安装一个或多个动态共享对象到服务器的modules目录中。
- -a 此选项自动增加一个LoadModule行到httpd.conf文件中,以激活此模块,或者,如果此行已经存在,则启用之。
- -A 与 -a 选项类似,但是它增加的LoadModule命令有一个井号前缀(#),即此模块已经准备就绪但尚未启用。
- -c 此选项表示需要执行编译操作。它首先会编译C源程序(.c)files为对应的目标代码文件(.o),然后连接这些目标代码和files中其余的目标代码 文件(.o和.a),以生成动态共享对象dsofile 。如果没有指定 -o 选项,则此输出文件名由files中的第一个文件名推测得到,也就是默认为mod_name.so 。
PS:安装此模块后,一定要检查下配置文件语法
- # apachectl -t
如果出现这样的错误
- httpd: Syntax error on line 58 of /opt/apache/conf/httpd.conf: Cannot load /opt/apache/modules/mod_deflate.so into server: /opt/apache/modules/mod_deflate.so: undefined symbol: inflateEnd
解决办法有二
办法1
- 需要在 LoadModule deflate_module modules/mod_deflate.so 的前面加载zlib.so
- a.32操作系统增加以下内容:
- LoadFile /usr/lib/libz.so
- LoadModule deflate_module modules/mod_deflate.so
- b.64操作系统增加以下内容:
- LoadFile /usr/lib64/libz.so
- LoadModule deflate_module modules/mod_deflate.so
办法2
- vi /usr/local/apache2/bin/apr-config
- 修改LDFLAGS=" " 为 LDFLAGS="-lz"
- 然后再apxs -i -c -a mod_deflate.c
