图形化安装数据库软件，创建数据库，配置监听大家都很熟悉了，本篇博客分为几部分来演示应答方式（response）安装数据库软件、创建数据库等操作。
这种方式的好处是可以深入了解没有安装配置的细节。
首先来看一张OFA的脉络图，虽然生产环境总会自定义这些路径，但是总的框架还是不会变的。
OFA标准中的几个重要目录：
|
oracle清单目录
|
oraInventory
|
/u01/app/oraInventory
|
|
oracle基础目录
|
ORACLE_BASE
|
/u01/app/oracle
|
|
oracle主目录
|
ORACLE_HOME
|
/u01/app/oracle/product/12.1.0/db_1
如果环境中有测试、开发可以在这里用db_1, db_2来区分；
如果只有一个生产环境可以去掉db_1
/u01/app/oracle/product/12.1.0 生产
/u01/app/oracle/product/12.1.0/db_1 开发
/u01/app/oracle/product/12.1.0/db_2 测试
|
|
oracle网络目录
|
TNS_ADMIN
|
/u01/app/oracle/product/12.1.0/db_1/network/admin
|
|
自动诊断库目录
|
ADR_HOME
|
/u01/app/oracle/diag/rdbms/db_unique_name/instance_name
select value from v$diag_info where name=‘ADR Home‘
|
/u01为操作系统挂载点，通常会出现/u01,/u02,/u03等等。 如果命名为/ora01会一目了然该挂载点为oracle数据库所用。
下面开始准备工作
一，OS准备工作
主机名
[root@snow ~]# hostname
snow.oracle.com
hosts配置
[root@snow ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.228.12 snow.oracle.com
操作系统版本
[root@snow ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.6 (Santiago)
磁盘空间
[root@snow ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 36G 3.2G 31G 10% /
tmpfs 1.8G 72K 1.8G 1% /dev/shm
内存大小
[root@snow ~]# grep MemTotal /proc/meminfo
MemTotal: 3772548 kB
swap使用情况
[oracle@snow ~]$ free -t
total used free shared buffers cached
Mem: 3772548 3237804 534744 2372 44880 2819740
-/+ buffers/cache: 373184 3399364
Swap: 4194300 0 4194300
Total: 7966848 3237804 4729044
挂载OS安装光盘
[root@snow ~]# mount /dev/cdrom /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only
创建repos文件
root@snow ~]# cd /etc/yum.repos.d/
[root@snow yum.repos.d]# mv public-yum-ol6.repo public-yum-ol6.repo.bak
[root@snow yum.repos.d]# vi snow12c.repo
[Oracle]
name=OEL-$releasever - Media
baseurl=file:///mnt
gpgcheck=0
enabled=1
创建组、用户、安装rpm包
[root@snow yum.repos.d]# yum install oracle-rdbms-server-12cR1-preinstall
检测组、用户创建效果
[oracle@snow ~]$ id oracle
uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba)
修改oracle密码
root@snow yum.repos.d]# passwd oracle
Changing password for user oracle
cat /etc/group
cat /etc/passwd
如果不符合要求可以修改或删除
groupmod/groupdel
usremode/userdel
修改限制文件
[root@snow yum.repos.d]# vi /etc/security/limits.conf
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft stack 10240
oracle hard stack 32768
禁用防火墙
# service iptables stop
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
禁用SELINUX，注意黄色字体
[root@snow yum.repos.d]# vi /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
创建oracle安装目录
[root@snow yum.repos.d]# mkdir -p /u01/app/oracle
[root@snow yum.repos.d]# chown -R oracle:oinstall /u01
[root@snow yum.repos.d]# chmod -R 775 /u01
二，数据库软件准备工作
创建安装介质目录
su - oracle
[oracle@snow ~]$ mkdir -p orainst/12.1.0.1
ftp上传介质到指定目录
ftp linux_12c_database_1of2.zip /home/oracle/orainst/12.1.0.1
ftp linux_12c_database_2of2.zip /home/oracle/orainst/12.1.0.1
解压缩安装包
cd /home/oracle/orainst/12.1.0.1
unzip linux_12c_database_1of2.zip
unzip linux_12c_database_2of2.zip
创建oraInst.loc
$ cat /etc/oraInst.loc
inventory_loc=/u01/app/oraInventory
inst_group=oinstall
chown oracle:oinstall oraInst.loc
chmod 664 oraInst.loc
配置bash_profile
cd /home/oracle
[oracle@snow ~]$ vi .bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0.1/db_1
export ORACLE_SID=cdb
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
stty erase ^h
[oracle@snow ~]$ . .bash_profile
检查环境变量是否生效
[oracle@snow ~]$ env|grep ORA
ORACLE_SID=cdb
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/12.1.0/db_1
三，配置应答文件
复制一个应答文件作为模板来修改
通常应答文件在数据库软件解压缩路径下的response
cd /home/oracle/orainst/12.1.0.1/database/response
-rwxrwxr-x. 1 oracle oinstall 58021 Aug 29 2012 dbca.rsp
-rw-rw-r--. 1 oracle oinstall 26690 May 24 2013 db_install.rsp
-rwxrwxr-x. 1 oracle oinstall 6038 Jun 18 2012 netca.rsp
cp -rp db_install.rsp inst.rsp
修改后的inst.rsp如下
oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v12.1.0
oracle.install.option=INSTALL_DB_SWONLY
ORACLE_HOSTNAME=snow.oracle.com
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/u01/app/oraInventory
SELECTED_LANGUAGES=en
ORACLE_HOME=/u01/app/oracle/product/12.1.0.1
ORACLE_BASE=/u01/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=oper
oracle.install.db.BACKUPDBA_GROUP=dba
oracle.install.db.DGDBA_GROUP=dba
oracle.install.db.KMDBA_GROUP=dba
DECLINE_SECURITY_UPDATES=true
SECURITY_UPDATES_VIA_MYORACLESUPPORT=false
oracle.installer.autoupdates.option=SKIP_UPDATES
执行应答方式安装数据库
[oracle@snow database]$ ./runInstaller -ignoreSysPrereqs -force -silent -responseFile /home/oracle/orainst/12.1.0.1/database/response/inst.rsp
