1 安装前环境：
操作系统:CetnOS6.4x64 最小化安装，已配置好网络IP:172.18.10.213，物理内存4GB，硬盘100GB。
已下载： linux.x64_11gR2_database_1of2.zip
linux.x64_11gR2_database_2of2.zip
位于目录： /sharedisk/11G/
2 准备工作
root用户登录后
# yum install unzip //下载unzip,用来解压上述两个压缩文件
# cd /sharedisk/11G //切换当前目录到Oracle压缩文件所在目录
# unzip linux.x64_11gR2_database_1of2.zip //解压
# unzip linux.x64_11gR2_database_2of2.zip
解压后新增一个/sharedisk/11G/database目录，里面是解压后的所有oracle安装文件。
在/etc/hosts文件中增加主机名(通过hostname获得)到回环IP的映射如下：
# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.18.10.213 ora11g
# vi /etc/selinux/confg 设置 SELINUX=disabled
# setenforce 0 //关闭selinux
# service iptables stop //临时关闭防火墙
3 安装必须的包
# yum install nfs-utils //可以挂载nfs server
#yum install gcc make binutils gcc-c++ compat-libstdc++-33 elfutils-libelf-devel elfutils-libelf-devel-static ksh libaio libaio-devel numactl-devel sysstat unixODBC unixODBC-devel pcre-devel
4 准备安装用户及用户组
# groupadd oinstall
# groupadd dba
# useradd -g oinstall -G dba oracle
# passwd oracle //设置oracle密码
5 修改内核参数配置文件
# vi /etc/sysctl.conf 在文件最后增加（根据文档要求kernel.shmmax设成物理内存的一半最合理）
fs.aio-max-nr = 1048576
fs.file-max = 6553600
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
保存文件。
# /sbin/sysctl -p //让参数生效
6 修改用户的限制文件
# vi /etc/security/limits.conf 在文件后增加
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
保存文件。
修改/etc/pam.d/login文件，增加如下：
session required /lib64/security/pam_limits.so //64位系统时，千万别写成错/lib/security/pam_limits.so //否则导致无法登录
session required pam_limits.so
修改/etc/profile,增加：
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
7 创建安装目录和设置文件权限
#mkdir -p /u01/app/oracle/product/11.2.0 //数据库系统安装目录
#mkdir /u01/app/oracle/oradata //数据库数据安装目录
#mkdir /u01/app/oracle/inventory
#mkdir /u01/app/oracle/fast_recovery_area
#chown -R oracle:oinstall /u01/app/oracle
#chmod -R 775 /u01/app/oracle
设置环境变量: 修改/home/oracle/.bash_profile文件，增加如下
# su - oracle
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=$ORACLE_BASE/product/11.2.0
ORACLE_SID=ora11
PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH
8 编辑静默安装响应文件
# su - oracle
$ cp -R /sharedisk/11G/database/response /home/oracle //复制一份模板
$ cd /home/oracle/response
$ vi db_install.rsp //开始修改这个安装响应文件，此文件只是安装数据库软件
需要设置的选项如下：
oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v11_2_0 //系统生成的，不要修改
oracle.install.option=INSTALL_DB_SWONLY //只安装软件，不安装启动数据库
ORACLE_HOSTNAME=ora11g //通过hostname命令获得
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/u01/app/oracle/inventory
SELECTED_LANGUAGES=en,zh_CN
ORACLE_HOME=/u01/app/oracle/product/11.2.0
ORACLE_BASE=/u01/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.isCustomInstall=false
oracle.install.db.customComponents=oracle.server:11.2.0.1.0,oracle.sysman.ccr:10.2.7.0.0,oracle.xdk:11.2.0.1.0,oracle.rdbms.oci:11.2.0.1.0,oracle.network:11.2.0.1.0,oracle.network.listener:11.2.0.1.0,oracle.rdbms:11.2.0.1.0,oracle.options:11.2.0.1.0,oracle.rdbms.partitioning:11.2.0.1.0,oracle.oraolap:11.2.0.1.0,oracle.rdbms.dm:11.2.0.1.0,oracle.rdbms.dv:11.2.0.1.0,orcle.rdbms.lbac:11.2.0.1.0,oracle.rdbms.rat:11.2.0.1.0
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=dba
DECLINE_SECURITY_UPDATES=true //一定要设置为true
9 根据响应文件安装oracle
$cd /sharedisk/11G/database
$./runInstaller -silent -responseFile /home/oracle/response/db_install.rsp -ignorePrereq
安装过程中，如果提示[WARNING]不必理会，此时安装程序仍在进行，如果出现[FATAL]，则安装程序已经停止了。打开另一个终端，执行
#tail -100f /u01/app/oracle/inventory/logs/installActions......log
可以实时跟踪查看安装日志，了解安装的进度。
当出现如下提示，既安装成功：
be executed as the "root" user.
#!/bin/sh
#Root scripts to run
/u01/app/oracle/inventory/orainstRoot.sh
/u01/app/oracle/product/11.2.0/root.sh
To execute the configuration scripts:
1. Open a terminal window
2. Log in as "root"
3. Run the scripts
4. Return to this window and hit "Enter" key to continue
Successfully Setup Software.
表示安装成功了。按照其提示操作。
$exit //退回到root
# sh /u01/app/oracle/inventory/orainstRoot.sh
# sh /u01/app/oracle/product/11.2.0/root.sh
10 静默配置监听
$netca /silent /responsefile /home/oracle/response/netca.rsp
Parsing command line arguments:
Parameter "silent" = true
Parameter "responsefile" = /home/oracle/response/netca.rsp
Done parsing command line arguments.
Oracle Net Services Configuration:
Profile configuration complete.
Oracle Net Listener Startup:
Running Listener Control:
/u01/app/oracle/product/11.2.0/bin/lsnrctl start LISTENER
Listener Control complete.
Listener started successfully.
Listener configuration complete.
Oracle Net Services configuration successful. The exit code is 0
成功运行后，在/u01/app/oracle/11.2.0/network/admin目录下生成sqlnet.ora和listener.ora两个文件。
通过netstat –tlnp 命令，看到
tcp 0 0 :::1521 :::* LISTEN 10760/tnslsnr
说明监听器已经在1521端口上开始工作了。
11 静默建立新库（同时也建立一个对应的实例）
修改/home/oracle/response/dbca.rsp，设置如下：
[GENERAL]
RESPONSEFILE_VERSION = "11.2.0" //不能更改
OPERATION_TYPE = " createDatabase "
[CREATEDATABASE]
GDBNAME = "ora11" //数据库的名字
SID = "ora11" //对应的实例名字
TEMPLATENAME = "General_Purpose.dbc" //建库用的模板文件
SYSPASSWORD = "oracle" //SYS管理员密码
SYSTEMPASSWORD = "oracle" //SYSTEM管理员密码
DATAFILEDESTINATION = /u01/app/oracle/oradata //数据文件存放目录
RECOVERYAREADESTINATION=/u01/app/oracle/fast_recovery_area //恢复数据存放目录
CHARACTERSET = "ZHS16GBK" //字符集，重要!!! 建库后一般不能更改，所以建库前要确定清楚。
TOTALMEMORY = "3276" //oracle内存3276MB(allmem*80%)
静默建库命令如下
$dbca -silent -responseFile /home/oracle/response/dbca.rsp

13 修改oracle启动配置文件
$vi /etc/oratab
ora11:/u01/app/oracle/product/11.2.0:Y
这样就可以通过dbstart 启动此实例，也可以通过dbshut关闭此实例了。
$ dbshut /u01/app/oracle/product/11.2.0
Processing Database instance "ora11": log file /u01/app/oracle/product/11.2.0/shutdown.log
此时所有oracle的进程关闭，监听器也停止。
$dbstart /u01/app/oracle/product/11.2.0
Processing Database instance "ora11": log file /u01/app/oracle/product/11.2.0/startup.log
此时监听器工作，hello实例运行，再次查看监听器状态。
$ lsnrctl status
开机启动方法：
方法1：
要想让oracle服务随着系统启动而自动启动，需要在/etc/rc.local文件中增加如下：
su - oracle -c "/u01/app/oracle/product/11.2.0/bin/dbstart /u01/app/oracle/product/11.2.0"
方法2：建立启动脚本
# vi /etc/rc.d/init.d/oracle
#!/bin/bash
# oracle: Start/Stop Oracle Database 11g R2
#
# chkconfig: 345 90 10
# description: The Oracle Database is an Object-Relational Database Management System.
