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
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

# 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
Header set Cache-Control “max-age=2592000, public”
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
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
