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

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
