Oracle Database 从 19C 开始还提供了 RPM 包方式进行安装，RPM 包安装方式简单，且能够通过 RPM 进行管理，但是无法决定安装目录，默认是安装在 /opt 目录下。

安装 preinstall RPM 包

oracle-database-preinstall-19c RPM 包帮助配置安装之前所需的用户和内核参数的配置，默认 YUM 源和光盘中已经提供了，直接安装即可：

1
[root@oel7-3 ~]# yum install -y oracle-database-preinstall-19c.x86_64

安装数据库软件

使用 RPM 安装要确保 /opt 目录有 7G 空闲空间，直接安装：

1
[root@oel7-3 ~]# yum localinstall -y oracle-database-ee-19c-1.0-1.x86_64.rpm

创建数据库实例

可以使用 dbac 图形化或静默创建，也可以通过以下方式创建：

虽然生产环境中使用这种方式较少，但个人感觉这比 ZIP 安装方式要简单的多，也有可能是新推出而不被老手所接受，习惯了老式的安装方式。
