安装 19c 的 rpm 版本非常简洁，和 18c 一致：

以下是 19c 中的步骤。
首先下载 preinstall 包：
[root@sdb0 ~]# curl -o oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

通过下载在本地的安装包进行安装：
[root@sdb0 ~]# yum -y localinstall oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

最后记录一下 preinstall 这个文件中的内容，其实可以看出预先所做的工作：
[root@sdb0 ~]# strings oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
