安装

首先执行

[root@linuxtestb538 oracle]# rpm -ivh oracle-database-preinstall-19c-1.0-3.el7.x86_64.rpm

安装 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

配置数据库

/etc/init.d/oracledb_ORCLCDB-19c configure
100% complete
Database creation complete. For details check the logfiles at:
 /opt/oracle/cfgtoollogs/dbca/ORCLCDB.
Database Information:
Global Database Name:ORCLCDB
System Identifier(SID):ORCLCDB
Look at the log file "/opt/oracle/cfgtoollogs/dbca/ORCLCDB/ORCLCDB.log" for further details.

Database configuration completed successfully. The passwords were auto generated, you must change them by connecting to the database using 'sqlplus / as sysdba' as the oracle user.

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=ORCLCDB
export 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）

验证安装是否正确

su oracle   (用户切换到oracle用户)
sysplus / as sysdba
