想看到它壓縮的功能，我們放一張照片到默認網頁中去試一試[root@localhost abc]# cd /abc/[root@localhost abc]# lsapr-1.6.2.tar.gz ?????????????????Discuz_X2.5_SC_UTF8.zip ?mysql-5.6.26.tar.gzapr-util-1.6.0.tar.gz ????????????fiddler.exe ?????????????php-5.6.11.tar.bz2awstats-7.6.tar.gz ???????????????httpd-2.4.29.tar.bz2 ????tu9892_14.jpg #這是我們的圖片cronolog-1.6.2-14.el7.x86_64.rpm ?LAMP-php5.6.txt[root@localhost abc]# cp tu9892_14.jpg /usr/local/httpd/htdocs/ #把這種照片復制到默認首頁中[root@localhost abc]# cd /usr/local/httpd/htdocs/[root@localhost htdocs]# lsindex.html ?tu9892_14.jpg[root@localhost htdocs]# vim index.html<html><body><h2>It works!</h2><img src="tu9892_14.jpg"/></body></html>去客戶機測試一下壓縮功能?
網頁之緩存時間優(yōu)化通過mod_expire模塊配置Apache，使網頁在客戶端瀏覽器緩存一段時間，以免重復請求，降低客戶段的訪問頻率和次數(shù)，達到減少不必要的流量和增加訪問速度的目的?
前面的步驟更壓縮一樣，我們直接到主配置文件中開啟緩存模塊Listen 192.168.136.136:80 ?#開啟監(jiān)聽地址#Listen 80 ??#關閉IPV6監(jiān)聽地址ServerName www.kgc.com:80 #開啟域名服務器LoadModule expires_module modules/mod_expires.so #開啟模塊配置文件末尾添加<IfModule mod_expires.c> ?ExpiresActive On ?#開啟功能 ?ExpiresDefault "access plus 31104000 seconds" ?#開啟緩存時間31104000s</IfModule>驗證語法格式有沒有錯誤[root@localhost conf]# cd /usr/local/httpd/[root@localhost httpd]# cd bin/[root@localhost bin]# ./apachectl -tSyntax OK開啟服務查看端口有沒有被提供出來[root@localhost bin]# ./apachectl start[root@localhost bin]# netstat -ntap | grep 80tcp ???????0 ?????0 192.168.136.136:80 ?????0.0.0.0:* ??????????????LISTEN ?????52832/httpd ????????[root@localhost bin]# systemctl stop firewalld.service [root@localhost bin]# setenforce 0查看緩存模塊有沒有被啟動[root@localhost bin]# ./apachectl -t -D DUMP_MODULES | grep "expires" expires_module (shared)去客戶段去測試一下
