nginx做负载均衡服务器，配置动静分离
目录
部署LNMP(nginx1.22+mysql8.0+php8.1)
部署LAMP(httpd2.4+mysql8.0+php8.1)
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
环境说明:
| 系统 | ip | 主机名 | 服务 |
|---|---|---|---|
| centos8 | 192.168.222.250 | RS1 | LNMP,动态资源,静态资源 |
| centos8 | 192.168.222.137 | RS2 | LAMP,静态资源,动态资源 |
| centos8 | 192.168.222.139 | node1 | nginx,负载均衡服务器 |
