Linux7.9安装LNMP

1、安装MariaDB/MySQL
 
CentOS/RHEL7使用了MariaDB替代了默认的MySQL。作为MySQL的简单替代品，MariaDB保证了与MySQL的API和命令行用法方面最大的兼容性。下面是关于怎么在 CentOS7上安装和配置MaraDB/MySQL的操作示例。
 
yum install mariadb-server
systemctl start mariadb
systemctl enable mariadb
 
在成功启动MariaDB/MySQL服务后，还要进行数据库的安全配置，如设置（非空）的root密码、删除匿名用户、锁定远程访问。执行如下代码：
mysql_secure_installation
根据提示设置root密码，以及删除匿名用户等操作

2安装PHP7.2

#查询是否安装过php
yum list installed | grep php
yum provides php
