在VirtualBox上安装一台OL7u5的虚机,8G内存,一个vCPU,一块网卡(NAT,以便从公网下载包)。我是从现成的模板导入的。

从OTN或E-Delivery下载。
版本为12.2.0.1,分为两个zip文件,分别用于数据库安装和Grid Infrastructure安装。
将安装介质所在目录共享到虚机,然后解压,解压后大约3.6G:

先决条件包安装完毕后,oracle用户及相关组已建立:
# id oracle
uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba),54323(oper),54324(backupdba),54325(dgdba),54326(kmdba),54330(racdba)
安装数据库软件用户,此处为oracle,必须属于oinstall和dba组,其中oinstall必须是主组。
此处的/u01/app/oracle其实就是ORACLE_BASE:
mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01
chmod -R 775 /u01
按照Optimal Flexible Architecture (OFA)建议的目录结构,ORACLE_HOME应为:
/u01/app/oracle/product/12.2.0/dbhome_1
安装使用OUI(Oracle Universal Installer)。OUI不允许用root运行,否则报错:
# ./runInstaller
The user is root. Oracle Universal Installer cannot continue installation if the user is root.
使用oracle用户启动OUI:
# su - oracle

# ls /u01/app/oraInventory
ContentsXML logs oraInst.loc orainstRoot.sh oui
由于数据库尚未创建,因此oratab文件暂无条目:

# This file is used by ORACLE utilities. It is created by root.sh
# and updated by either Database Configuration Assistant while creating
# a database or ASM Configuration Assistant while creating ASM instance.
# A colon, ':', is used as the field terminator. A new line terminates
# the entry. Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form:
# $ORACLE_SID:$ORACLE_HOME::
#
# The first and second fields are the system identifier and home
# directory of the database respectively. The third field indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.
#
#

在~oracle/.bash_profile中设置环境变量:
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.2.0/dbhome_1
export PATH=$ORACLE_HOME/bin:$PATH
因为dbca在$ORACLE_HOME/bin目录中,必须将此目录放在PATH的最前面。
然后运行dbca:
$ dbca
$ tail -1 /etc/oratab
orcl:/u01/app/oracle/product/12.2.0/dbhome_1:N
验证可以登录数据库:
$ export ORACLE_SID=orcl
