1.环境描述

step 1.Download the relevant RPM from download page here.

• OL7 : oracle-database-ee-21c-1.0-1.ol7.x86_64.rpm
• OL8 : oracle-database-ee-21c-1.0-1.ol8.x86_64.rpm

step 2.Set the correct hostname in the “/etc/hostname” file.

2.Oracle Installation

Download the relevant RPM from download page here.

• OL7 : oracle-database-ee-21c-1.0-1.ol7.x86_64.rpm
• OL8 : oracle-database-ee-21c-1.0-1.ol8.x86_64.rpm

step 1.安装数据库 RPM 之前手动运行它

# RHEL7
curl -o oracle-database-preinstall-21c-1.0-1.el7.x86_64.rpm https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-21c-1.0-1.el7.x86_64.rpm
yum -y localinstall oracle-database-preinstall-21c-1.0-1.el7.x86_64.rpm
rm oracle-database-preinstall-21c-1.0-1.el7.x86_64.rpm

# RHEL8
curl -o oracle-database-preinstall-21c-1.0-1.el8.x86_64.rpm https://yum.oracle.com/repo/OracleLinux/OL8/appstream/x86_64/getPackage/oracle-database-preinstall-21c-1.0-1.el8.x86_64.rpm
yum -y localinstall oracle-database-preinstall-21c-1.0-1.el8.x86_64.rpm
rm oracle-database-preinstall-21c-1.0-1.el8.x86_64.rpm

step 2.安装数据库软件

# OL7
# yum install -y oracle-database-preinstall-21c
yum -y localinstall oracle-database-ee-21c-1.0-1.ol7.x86_64.rpm

# OL8
# dnf install -y oracle-database-preinstall-21c
dnf -y localinstall oracle-database-ee-21c-1.0-1.ol8.x86_64.rpm

The ORACLE_HOME for the software installation is “/opt/oracle/product/21c/dbhome_1”.

3.创建数据库

除了软件安装之外，RPM 还创建了一个脚本，允许您创建一个名为“ORCLCDB”的演示数据库，以及一个名为“ORCLPDB1”的可插拔数据库 (PDB)。

# /etc/init.d/oracledb_ORCLCDB-21c configure

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.

您当然可以使用数据库配置助手 (DBCA) 以正常方式创建数据库。 您不必使用此脚本。
