在非OralceLinux环境下安装，需要下载对应平台的rpm。

下载地址：

https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/index.html，搜索-19c下载最新版本即可。

安装，首先执行

[root@linuxtestb538 oracle]# rpm -ivh oracle-database-preinstall-19c-1.0-3.el7.x86_64.rpm warning: oracle-database-preinstall-19c-1.0-3.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEYerror: Failed dependencies:        bind-utils is needed by oracle-database-preinstall-19c-1.0-3.el7.x86_64        compat-libcap1 is needed by oracle-database-preinstall-19c-1.0-3.el7.x86_64        ksh is needed by oracle-database-preinstall-19c-1.0-3.el7.x86_64        smartmontools is needed by oracle-database-preinstall-19c-1.0-3.el7.x86_64        sysstat is needed by oracle-database-preinstall-19c-1.0-3.el7.x86_64        xorg-x11-utils is needed by oracle-database-preinstall-19c-1.0-3.el7.x86_64

执行出现缺少依赖错误。

改用yum命令进行安装

yum install oracle-database-preinstall-19c-1.0-3.el7.x86_64.rpm Installed:oracle-database-preinstall-19c.x86_64 0:1.0-3.el7

配置好后设置当前用户下的环境变量

vi ~/.bashrc    (打开文件后追加oracle的环境变量信息)---------------------------------------------------export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1 export ORACLE_SID=ORCLCDBexport PATH=$ORACLE_HOME/bin:$PATH---------------------------------------------------
通过运行source ~/.bashrc  （命令运行后设置的环境变量生效）
