nginx动静分离[centos7、centos8]

动静分离:
服务器配置:
动态资源 吃cpu和内存,动态资源放在cpu多、内存大的服务器上
静态资源 吃硬盘和带宽,静态资源放在硬盘大、带宽高的服务器上

【centos8系统】
#准备三台服务器 105:反向代理服务器  106:静态服务器  107:动态服务器
#准备三台nginx[nginx/1.20.2]  在www.nginx.org->download->Linux packages for stable and mainline versions.-> RHEL/CentOS->

动态资源配置:  #centos8默认的php是7版本,centos7默认的php是5版本,所以用centos7系统要装下面的源
yum 安装php7.1
