装置环境
cat /etc/redhat-release CentOS Linux release 7.7.1908 (Core)在非OralceLinux环境下装置，须要下载对应平台的rpm。
下载地址：https://yum.oracle.com/repo/O...，搜寻-19c下载最新版本即可。
装置
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执行呈现短少依赖谬误。
改用yum命令进行装置
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 Dependency Installed: GeoIP.x86_64 0:1.5.0-14.el7 bind-libs.x86_64 32:9.11.4-26.P2.el7_9.7 bind-libs-lite.x86_64 32:9.11.4-26.P2.el7_9.7 bind-license.noarch 32:9.11.4-26.P2.el7_9.7 bind-utils.x86_64 32:9.11.4-26.P2.el7_9.7 compat-libcap1.x86_64 0:1.10-7.el7 geoipupdate.x86_64 0:2.5.0-1.el7 ksh.x86_64 0:20120801-142.el7 smartmontools.x86_64 1:7.0-2.el7 sysstat.x86_64 0:10.1.5-19.el7 xorg-x11-utils.x86_64 0:7.5-23.el7 Complete!装置Oracle数据库
yum install oracle-database-ee-19c-1.0-1.x86_64.rpm Installed: oracle-database-ee-19c.x86_64 0:1.0-1 Complete!配置数据库

vi ~/.bashrc (关上文件后追加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失效）验证装置是否正确
