apache网页优化之压缩功能和缓存时间

Apache网页优化 
优化概述 
压缩功能优化配置Apache的网页压缩功能，是使用gzip压缩算法对网页内容进行压缩后再传输到客户端浏览器

想看到它压缩的功能，我们放一张照片到默认网页中去试一试[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 #这是我们的图片cronolog-1.6.2-14.el7.x86_64.rpm  LAMP-php5.6.txt[root@localhost abc]# cp tu9892_14.jpg /usr/local/httpd/htdocs/ #把这种照片复制到默认首页中[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>去客户机测试一下压缩功能 
网页之缓存时间优化通过mod_expire模块配置Apache，使网页在客户端浏览器缓存一段时间，以免重复请求，降低客户段的访问频率和次数，达到减少不必要的流量和增加访问速度的目的 
前面的步骤更压缩一样，我们直接到主配置文件中开启缓存模块Listen 192.168.136.136:80  #开启监听地址#Listen 80   #关闭IPV6监听地址ServerName www.kgc.com:80 #开启域名服务器LoadModule expires_module modules/mod_expires.so #开启模块配置文件末尾添加<IfModule mod_expires.c>  ExpiresActive On  #开启功能  ExpiresDefault "access plus 31104000 seconds"  #开启缓存时间31104000s</IfModule>验证语法格式有没有错误[root@localhost conf]# cd /usr/local/httpd/[root@localhost httpd]# cd bin/[root@localhost bin]# ./apachectl -tSyntax OK开启服务查看端口有没有被提供出来[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查看缓存模块有没有被启动[root@localhost bin]# ./apachectl -t -D DUMP_MODULES | grep "expires" expires_module (shared)去客户段去测试一下
