这篇文章主要介绍了OL7.6中如何通过RPM方式安装Oracle 19c，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

设置主机名

[root@localhost~]#cat/etc/hosts127.0.0.1localhostlocalhost.localdomainlocalhost4localhost4.localdomain4::1localhostlocalhost.localdomainlocalhost6localhost6.localdomain610.0.0.11study1.localdomainstudy1[root@localhost~]#cat/etc/hostnamestudy1.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-yinstalloracle-database-preinstall-19cLoadedplugins:langpacks,ulninfool7_UEKR5|2.5kB00:00:00ol7_latest|2.7kB00:00:00(1/4):ol7_UEKR5/x86_64/updateinfo|49kB00:00:01(2/4):ol7_latest/x86_64/updateinfo|1.1MB00:00:05(3/4):ol7_UEKR5/x86_64/primary_db|5.7MB00:00:27(4/4):ol7_latest/x86_64/primary_db|19MB00:01:21ResolvingDependencies(manymorelinessupressed)Installed:oracle-database-preinstall-19c.x86_640:1.0-1.el7DependencyInstalled:compat-libcap1.x86_640:1.10-7.el7compat-libstdc++-33.x86_640:3.2.3-72.el7glibc-devel.x86_640:2.17-292.0.1.el7glibc-headers.x86_640:2.17-292.0.1.el7kernel-headers.x86_640:3.10.0-1062.el7ksh.x86_640:20120801-139.0.1.el7libaio-devel.x86_640:0.3.109-13.el7libstdc++-devel.x86_640:4.8.5-39.0.1.el7DependencyUpdated:glibc.x86_640:2.17-292.0.1.el7glibc-common.x86_640:2.17-292.0.1.el7libstdc++.x86_640:4.8.5-39.0.1.el7Complete![root@study1/]#

如果是rhel或者centos，就要手工先下载preinstall的rmp包，然后本地安装(或者添加oracle linux的yum源来yum安装)

[root@study1/]#curl-ooracle-database-preinstall-19c-1.0-1.el7.x86_64.rpmhttps://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm%Total%Received%XferdAverageSpeedTimeTimeTimeCurrentDloadUploadTotalSpentLeftSpeed1001820410018204001803700:00:010:00:01--:--:--18059[root@study1/]#yum-ylocalinstalloracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

创建数据库

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
