  • Nginx做负载均衡服务器，配置动静分离3. 在134主机主机部署lnmp，在动态资源4.1 在128主机安装httpd，做静态资源4.2 在129主机源码安装nginx并配置负载均衡器，进行调度5. 配置负载均衡，129主机
1. 题目：后端RS服务器?台部署LNMP(nginx1.22+MySQL8.0+php8.0)，?台部署httpd 。要求nginx和php使?编译安装最后要通过访问nginx负载均衡服务器的IP看到动静分离的效果 。2. 环境和提供软件包2.1 提供软件包[root@node6 ~]# wget https://nginx.org/download/nginx-1.22.0.tar.gz https://www.php.NET/distributions/php-8.0.23.tar.gz[root@node6 ~]# lsanaconda-ks.cfgnginx-1.22.0.tar.gzmysql-8.0.20-linux-glibc2.12-x86_64.tar.xzphp-8.0.23.tar.gz[root@node6 ~]#2.2 环境 主机
