篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了OL7.6上RPM方式安装Oracle 19c相关的知识,希望对你有一定的参考价值。

设置主机名

[root@localhost ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.0.11 study1.localdomain study1
[root@localhost ~]# cat /etc/hostname
study1.localdomain

安装环境准备工具

其实直接rpm安装即可,它会自动解决依赖问题包括环境准备工具,但是这样oracle用户没有home目录,所以单独先安装环境准备工具

[root@study1 /]# yum -y install oracle-database-preinstall-19c

这默认创建了名为ORCLCDB且pdb名ORCLPDB1的数据库,当然可以不用这么创建,用传统的dbca方式

优缺点

实际上这个方式并没有什么用,比起来静默安装也并没有显得更容易,只能安装数据库软件,并不能升级数据库,而且不能用于rac,只能用于安装单实例数据库,整个部署没有给予定制空间比如oracle_home目录如果和你公司的磁盘规划不一致呢,不过新手可能认为这样更简单,这个方式仅试试而已体会一下,实际生产中几乎是不能用的
