压缩文件:
编辑apache模块
vim /etc/httpd/conf.modules.d/00-base.conf
确保以下三个模块没有被注释
LoadModule headers_module modules/mod_headers.so LoadModule deflate_module modules/mod_deflate.so LoadModule filter_module modules/mod_filter.so
注意:也可以把三个模块放到/etc/httpd/conf/httpd.conf文件里,模块只能在一个文件中加载
设置压缩规则
vim /etc/httpd/conf/httpd.conf
末尾添加
<IfModule mod_deflate.c> AddOutputFilterByType DEFLATE application/javascript AddOutputFilterByType DEFLATE application/rss+xml AddOutputFilterByType DEFLATE application/vnd.ms-fontobject AddOutputFilterByType DEFLATE application/x-font AddOutputFilterByType DEFLATE application/x-font-opentype AddOutputFilterByType DEFLATE application/x-font-otf AddOutputFilterByType DEFLATE application/x-font-truetype AddOutputFilterByType DEFLATE application/x-font-ttf AddOutputFilterByType DEFLATE application/x-javascript AddOutputFilterByType DEFLATE application/xhtml+xml AddOutputFilterByType DEFLATE application/xml AddOutputFilterByType DEFLATE application/x-httpd-php AddOutputFilterByType DEFLATE application/x-httpd-fastphp AddOutputFilterByType DEFLATE font/opentype AddOutputFilterByType DEFLATE font/otf AddOutputFilterByType DEFLATE font/ttf AddOutputFilterByType DEFLATE image/svg+xml AddOutputFilterByType DEFLATE image/x-icon AddOutputFilterByType DEFLATE text/css AddOutputFilterByType DEFLATE text/html AddOutputFilterByType DEFLATE text/javascript AddOutputFilterByType DEFLATE text/plain AddOutputFilterByType DEFLATE text/xml # Remove browser bugs (only needed for really old browsers) BrowserMatch ^Mozilla/4 gzip-only-text/html BrowserMatch ^Mozilla/4\.0[678] no-gzip BrowserMatch \bMSIE !no-gzip !gzip-only-text/html #SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary #设置不对后缀gif,jpg,jpeg,png的图片文件进行压缩 Header append Vary User-Agent </IfModule>
压缩率一般都大于70%
压缩率检测(http://tool.chinaz.com/Gzips/)只能在pc端检测
设置缓存:
vim /etc/httpd/conf.modules.d/00-base.conf
确保以下模块没有被注释
LoadModule headers_module modules/mod_headers.so #第一种缓存方式 LoadModule expires_module modules/mod_expires.so #第二种缓存方式
注意:也可以把这个模块放到/etc/httpd/conf/httpd.conf文件里,模块只能在一个文件中加载
设置缓存规则
vim /var/www/html/.htaccess
末尾添加
第一种缓存方式
FileEtag INode Mtime Size
第二种缓存方式
# 缓存有效时间 1 月 <FilesMatch "\.(ico|jpg|jpeg|png|gif|js|css)$"> Header set Cache-Control "max-age=2592000, public" </FilesMatch> <FilesMatch "\.(html|txt|htm|php)$"> Header set Cache-Control "max-age=2592000, public, must-revalidate" </FilesMatch>
注意:max-age为缓存时间,单位秒,按需修改
第三种缓存方式
vim /etc/httpd/conf/httpd.conf
添加以下内容
<IfModule expires_module> ExpiresActive On #css文件缓存2592000/3600/24=1月 ExpiresByType text/css A2592000 #js文件缓存2592000/3600/24=1月 ExpiresByType application/x-javascript A2592000 ExpiresByType application/javascript A2592000 #html文件缓存2592000/3600/24=1月 ExpiresByType text/html A2592000 #图片文件缓存2592000/3600/24=1月 ExpiresByType image/jpg A2592000 ExpiresByType image/jpeg A2592000 ExpiresByType image/gif A2592000 ExpiresByType image/png A2592000 ExpiresByType image/ico A2592000 ExpiresByType image/x-icon A2592000 #文件默认缓存1月 ExpiresDefault "access plus 30 days" </IfModule>
注意:以上方式,三选一
重启apache服务
service httpd restart
注意:apache设置压缩和缓存都会增加服务器的内存压力,但设置压缩和缓存之后,网站的访问速度会有所提高
