使用静默方式安装Oracle数据库软件

使用的Linux 7 vagrant box，软件是Oracle Database 12.2.0.1版。
安装响应文件是从vagrant数据库安装中“偷”来的，如下：

oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v12.2.0
oracle.install.option=INSTALL_DB_SWONLY //只安装数据库软件
UNIX_GROUP_NAME=dba
INVENTORY_LOCATION=###ORACLE_BASE###/oraInventory
SELECTED_LANGUAGES=en
ORACLE_BASE=###ORACLE_BASE###
ORACLE_HOME=###ORACLE_HOME###
oracle.install.db.InstallEdition=###ORACLE_EDITION###
oracle.install.db.DBA_GROUP=dba
oracle.install.db.BACKUPDBA_GROUP=dba
oracle.install.db.DGDBA_GROUP=dba
oracle.install.db.KMDBA_GROUP=dba
oracle.install.db.OSRACDBA_GROUP=dba
SECURITY_UPDATES_VIA_MYORACLESUPPORT=false
DECLINE_SECURITY_UPDATES=true
oracle.installer.autoupdates.option=SKIP_UPDATES

其中###参数###是需要根据实际环境修改的，ORACLE_BASE设为/u01/app/oracle，ORACLE_HOME改为/u01/app/oracle/product/12.2.0.1/dbhome_1：

oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v12.2.0
oracle.install.option=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=dba
INVENTORY_LOCATION=/u01/app/oraInventory
SELECTED_LANGUAGES=en
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/12.2.0.1/dbhome_1
oracle.install.db.InstallEdition=EE
oracle.install.db.DBA_GROUP=dba
oracle.install.db.BACKUPDBA_GROUP=dba
oracle.install.db.DGDBA_GROUP=dba
oracle.install.db.KMDBA_GROUP=dba
oracle.install.db.OSRACDBA_GROUP=dba
SECURITY_UPDATES_VIA_MYORACLESUPPORT=false
DECLINE_SECURITY_UPDATES=true
oracle.installer.autoupdates.option=SKIP_UPDATES

将此文件存于/tmp/oracle/db_install.rsp
注意几个原则：

ORACLE_HOME应在ORACLE_BASE中
INVENTORY_LOCATION不要在ORACLE_BASE中
否则安装时会有警告：

   ACTION: Oracle recommends installing Oracle software within the Oracle base directory. Adjust the Oracle home or Oracle base accordingly.
[WARNING] [INS-32055] The Central Inventory is located in the Oracle base.ACTION: Oracle recommends placing this Central Inventory in a location outside the Oracle base directory.

静默安装

确认主机名

一定要确认主机名可以正确的解析，都是小写。确保以下地址可以ping通，且不是127.0.0.1：

ping $(hostname)

在实验环境中，我采用/etc/hosts解析，定义如下（注意第一行被注释了）：

# cat /etc/hosts
#127.0.0.1      ol7-vagrant     ol7-vagrant
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.2.15       ol7-vagrant

安装先决条件包

vagrant供应的是一个裸的Linux主机，因此先安装先决条件包：

# yum info oracle-database-server-12cR2-preinstall
Available Packages
Name        : oracle-database-server-12cR2-preinstall
Arch        : x86_64
Version     : 1.0
Release     : 5.el7
Size        : 19 k
Repo        : ol7_latest/x86_64
Summary     : Sets the system for Oracle Database single instance and Real Application Cluster install for Oracle Linux 7
License     : GPLv2
Description : The Oracle Preinstallation RPM package installs software packages and sets system parameters required for Oracle Database single instance and: Oracle Real Application Clusters installations version 12cR2 on Oracle Linux Release 7 Files affected: /etc/sysctl.conf, /boot/grub/menu.lst OR: /boot/grub2/grub.cfg Files added: /etc/security/limits.d/oracle-database-server-12cR2-preinstall.conf# yum install oracle-database-server-12cR2-preinstall

确认oracle用户已创建：

# id oracle
uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba),54323(oper),54324(backupdba),54325(dgdba),54326(kmdba),54330(racdba)

设置oracle用户口令：

# passwd oracle

创建目录结构

使用root用户

mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01
chmod -R 755 /u01

解压安装包

此处使用oracle用户。
解压到/tmp/oracle目录下，安装完成后记得删除此临时目录。另外，从18c开始，解压即安装，因此直接解压到$ORACLE_HOME下，而不是临时目录。

$ mkdir /tmp/oracle
$ unzip /vagrant/linuxx64_12201_database.zip -d /tmp/oracle

开始安装

整个过程执行了8分钟左右。

$ cd /tmp/oracle/database/
$ ./runInstaller -help$ ./runInstaller -silent -showProgress -responseFile /tmp/oracle/db_install.rsp

如上提示，安装完成后还需以root用户执行脚本：

# /u01/app/oraInventory/orainstRoot.sh

这些脚本的目的之一是需要在/etc目录下创建一些文件：

$ ls -l /etc/ora*
-rw-r--r--. 1 root   root      32 Aug  8 15:11 /etc/oracle-release
-rw-r--r--. 1 root   root      51 Sep  5 04:58 /etc/oraInst.loc

inst_group=dba$ cat /etc/oratab
## 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:<N|Y>:
#
# 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.
#
#

虽然是静默安装，但还是会进行先决条件检查。可能会有一些警告，如：

[WARNING] [INS-13014] Target environment does not meet some optional requirements.CAUSE: Some of the optional prerequisites are not met. See logs for details. installActions2019-09-07_06-19-13AM.logACTION: Identify the list of failed prerequisite checks from the log: installActions2019-09-07_06-19-13AM.log. Then either from the log file or from installation manual find the appropriate configuration to meet the prerequisites and fix it manually.
You can find the log of this install session at:/u01/app/oraInventory/logs/installActions2019-09-07_06-19-13AM.log

可以从日志文件中查看详细信息，本例是由于swap空间不够，这时可以忽略的：

$ grep VERIFICATION_FAILED /u01/app/oraInventory/logs/installActions2019-09-07_06-19-13AM.log
INFO: INFO: OverallStatus:VERIFICATION_FAILED
INFO: TaskSwapSize:Swap Size[CHECK_SWAP_SIZE]:TASK_SUMMARY:FAILED:IGNORABLE:VERIFICATION_FAILED:Total time taken [161 Milliseconds]
INFO: INFO: OverallStatus:VERIFICATION_FAILED

设置环境变量：

echo 'export ORACLE_BASE=/u01/app/oracle' >> ~/.bash_profile
echo 'export ORACLE_HOME=$ORACLE_BASE/product/12.2.0.1/dbhome_1' >> ~/.bash_profile
echo 'export PATH=$ORACLE_HOME/bin:$PATH' >> ~/.bash_profile

环境变量设置成功，则可以找到dbca的路径，下一个实验我们将使用其来创建数据库。

$ which dbca
/u01/app/oracle/product/12.2.0.1/dbhome_1/bin/dbca

清理临时安装文件

$ rm -fr /tmp/oracle

打补丁

首先给OPatch打补丁。打之前是12.2.0.1.4。

$ ./opatch version
OPatch Version: 12.2.0.1.6

然后给数据库打补丁。打之前的版本为（此时数据库软件已安装，但数据库未创建）：

由于还未创建任何数据库，只是删除数据库软件，因此很快。

以上只是卸载某一次数据库安装，Oracle Inventory还在。
如果想彻底清除，则还需以root用户执行以下：

# cd /etc
# rm oraInst.loc
rm: remove regular file ‘oraInst.loc’? y
# rm oratab
rm: remove regular file ‘oratab’? y
