apache 开启压缩记录
gzip压缩需要 deflate_module和headers_module的支持;系统默认就是开启的;
还需要开启 LoadModule deflate_module modules/mod_deflate.so
否则报错
AH00526: Syntax error on line 521 of /alidata/server/httpd/conf/httpd.conf:
Unknown filter provider DEFLATE
http.conf 里添加下面的配置
AddOutputFilterByType DEFLATE text/plain AddOutputFilterByType DEFLATE text/css AddOutputFilterByType DEFLATE application/xml AddOutputFilterByType DEFLATE application/rss+xml AddOutputFilterByType DEFLATE application/atom_xml AddOutputFilterByType DEFLATE application/x-javascript AddOutputFilterByType DEFLATE application/x-httpd-php AddOutputFilterByType DEFLATE text/html
重启apache
http://tool.chinaz.com/Gzips测试一下
看网上还有一种办法适用于不能随便重启apache的生产环境
