壓縮文件：

編輯apache模塊

vim /etc/httpd/conf.modules.d/00-base.conf

確保以下三個模塊沒有被注釋

LoadModule headers_module modules/mod_headers.so
LoadModule deflate_module modules/mod_deflate.so
LoadModule filter_module modules/mod_filter.so

注意：也可以把三個模塊放到/etc/httpd/conf/httpd.conf文件里，模塊只能在一個文件中加載

設置壓縮規則

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 #設置不對后綴gif，jpg，jpeg，png的圖片文件進行壓縮
Header append Vary User-Agent
</IfModule>

壓縮率一般都大于70%

壓縮率檢測（http://tool.chinaz.com/Gzips/）只能在pc端檢測

設置緩存：

vim /etc/httpd/conf.modules.d/00-base.conf

確保以下模塊沒有被注釋

LoadModule headers_module modules/mod_headers.so #第一種緩存方式
LoadModule expires_module modules/mod_expires.so #第二種緩存方式

注意：也可以把這個模塊放到/etc/httpd/conf/httpd.conf文件里，模塊只能在一個文件中加載

設置緩存規則

vim /var/www/html/.htaccess

末尾添加

第一種緩存方式

FileEtag INode Mtime Size

第二種緩存方式

# 緩存有效時間 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為緩存時間，單位秒，按需修改

第三種緩存方式

vim /etc/httpd/conf/httpd.conf

添加以下內容

<IfModule expires_module>
ExpiresActive On
#css文件緩存2592000/3600/24=1月
ExpiresByType text/css A2592000
#js文件緩存2592000/3600/24=1月
ExpiresByType application/x-javascript A2592000
ExpiresByType application/javascript A2592000
#html文件緩存2592000/3600/24=1月
ExpiresByType text/html A2592000
#圖片文件緩存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
#文件默認緩存1月
ExpiresDefault "access plus 30 days"
</IfModule>

注意：以上方式，三選一

重啟apache服務

service httpd restart

注意：apache設置壓縮和緩存都會增加服務器的內存壓力，但設置壓縮和緩存之后，網站的訪問速度會有所提高
