根据之前存储的PHP5已安装的Package，安装对应的PHP7.2的Package。

yum install mode_php72w php72w-cli php72w-mysqlnd
yum install php72w-fpm php72w-mbstring php72w-gd php72w-ldap php72w-pdo php72w-xml这些就是我服务器上全部需要安装的包。
重启Apache服务器
systemctl restart httpd生效可能需要几分钟，也可以直接重启服务器。
测试
在网站根目录下创建 info.php ,加入以下内容。

phpinfo()
?>通过访问服务器 IP/info.php 或 网址/info.php 查看当前PHP信息。
