今天为大家搭建一下基于CentOS7.9服务器部署LNMP，方便未来基于lnmp部署应用程序。
1.CentOS7.9基础配置
为了实现基于CentOS7.9服务器部署LNMP，CentOS7.9服务器需要满足一定的基础需要。具体参考：Linux常规基础配置_linux操作系统配置_小黑要上天的博客-CSDN博客
2.服务器信息
| HostName | IpAddress | OSVersion | Note |
| lnmp | 192.168.10.250 | CentOS Linux release 7.9.2009 (Core) |
3.lnmp实施部署
3.1.nginx1.24.0安装部署
-->更新网络yum源
命令：
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
[root@lnmp yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
