首先查看apache是否加载了mod_deflate.so模块，如果没有需要安装加载。找到并下载和当前apache版本相同的源码文件，解压缩到/home目录下，在apache安装目录下执行：
| /usr/local/apache2/bin/apxs -i -c /home/httpd-2.0.63/modules/filters/mod_deflate. |
会自动在 httpd.conf添加
| LoadModule deflate_module modules/mod_deflate.so |
添加如下设置：
| <IfModule mod_deflate.c> <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 \bMSIE !no-gzip !gzip-only-text/html # NOTE: Due to a bug in mod_setenvif up to Apache 2.0.59 # the above regex won’t work. You can use the following # workaround to get the desired effect: # BrowserMatch \bMSIE !no-gzip !gzip-only-text/html force-gzip BrowserMatch \bMSIE !no-gzip !gzip-only-text/html # Don’t compress images and other SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary SetEnvIfNoCase Request_URI .(?:pdf|doc)$ no-gzip dont-vary AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css AddOutputFilterByType DEFLATE application/x-javascript # Make sure proxies don’t deliver the wrong content Header append Vary User-Agent env=!dont-vary #DeflateFilterNote ratio ratio_info #LogFormat '"%v %h %l %u %t “%r" %>s %b "%{Referer}i" "%{User-Agent}i"" (%{ratio}n)' deflate #CustomLog logs/deflate_log deflate </Location> |
停止apache服务./apachectl stop，报错如下：
| Cannot load /usr/local/apache2/modules/mod_deflate.so into server: /usr/local/apache2/modules/mod_deflate.so: undefined symbol: deflate |
解决如下：
| vi /usr/local/apache2/bin/apr-config 修改LDFLAGS=" " 为 LDFLAGS="-lz" |
停止启动服务：仍提示：
| DeflateFilterNote not allowed here CustomLog not allowed here |
注释掉后，正常。
