在企业中，部署Apache后只采用默认的配置参数，会引发网站很多问题，换言之默认配置是针对以前较低的服务器配置的，以前的配置已经不适用当今互联网时代。
为了适应企业需求，就需要考虑如何提升Apache的性能与稳定性，这就是Apache优化的内容。
--------网页压缩--------
1.检查是否安装 mod_deflate 模块
apachectl -t -D DUMP_MODULES | grep "deflate"
2.如果没有安装mod_deflate 模块，重新编译安装 Apache 添加 mod_deflate 模块
systemctl stop httpd.service 
cd /usr/local/httpd/conf
mv httpd.conf httpd.conf.bak 
yum -y install gcc gcc-c++ pcre pcre-devel zlib-devel
cd /opt/httpd-2.4.29/
./configure \
--prefix=/usr/local/httpd \
--enable-so \
--enable-rewrite \
--enable-charset-lite \
--enable-cgi \
--enable-deflate #加入mod_deflate 模块
make && make install 
3.配置 mod_deflate 模块启用
vim /usr/local/httpd/conf/httpd.conf--52行--修改
Listen 192.198.80.10:80 
--105行--取消注释
LoadModule deflate_module modules/mod_deflate.so #开启mod_deflate 模块
--199行--取消注释，修改
ServerName www.kgc.com:80
--末行添加--
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/plain text/css text/xml text/javascript text/jpg text/png #代表对什么样的内容启用gzip压缩
DeflateCompressionLevel 9 #代表压缩级别，范围为1~9
SetOutputFilter DEFLATE #代表启用deflate 模块对本站点的输出进行gzip压缩
</IfModule> 
4.检查安装情况，启动服务
apachectl -t #验证配置文件的配置是否正确
apachectl -t -D DUMP_MODULES | grep "deflate" #检查 mod_deflate 模块是否已安装
deflate_module (shared) #已安装的正确结果
systemctl start httpd.service5.测试 mod_deflate 压缩是否生效
cd /usr/local/httpd/htdocs先将game.jpg文件传到/usr/local/httpd/htdocs目录下
vim index.html
