参考源文档：centos7 oracle11g静默安装
如下为本人亲验过程：
oracle11g（11.2.0.1.0）安装文档
1、准备Centos 7的系统环境
系统版本：CentOS Linux release 7.4.1708
内核版本：3.10.0-693.el7.x86_64
系统配置：1c,2G
交换空间:
可用内存 需要交换空间
介于1 GB和2 GB之间 RAM大小的1.5倍
介于2 GB和16 GB之间 等于RAM的大小
超过16 GB 16 GB
手动增加交换分区容量
dd if=/dev/zero of=/swap bs=1M count=2048
mkswap /swap
swapon /swap
echo "/swap swap swap defaults 0 0">>/etc/fstab
配置主机名
hostnamectl set-hostname x101
echo "127.0.0.1 x101" >>/etc/hosts
2、下载oracle软件包
下载网址：www.oracle.com，选择support------Software Downloads------Oracle Database 11g Release 2(11.2.0.1.0)Linux x86-64.
3、安装依赖包
yum -y install binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat unixODBC unixODBC-devel
我使用的是阿里云yum源，如果您用的是其它环境的，没有哪个依赖包，就手动装下即可。
4、创建所需的操作系统组和用户
如果要安装Oracle数据库，则需要以下本地操作系统组和用户：
Oracle inventory组(通常为 oinstall)
OSDBA组 (通常为 dba)
OSOPER组 (通常为 oper)
Oracle软件所有者(通常为 oracle)
groupadd oinstall
groupadd dba
groupadd oper
useradd -g oinstall -G dba oracle
修改oracle用户密码
echo "oracle"|passwd --stdin oracle
5、配置内核参数和资源限制
1.在/etc/sysctl.conf添加如下参数，如果系统中某个参数高于下面的参数的值 ，保留较大的值,下面的数值只是官方要求的最小值，可以根据系统调整数值，以优化系统性能
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
2.使内核参数生效
sysctl -p
3.在/etc/security/limits.conf中添加如下参数
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
4.在/etc/pam.d/login文件中，添加下面内容
session required /lib64/security/pam_limits.so
session required pam_limits.so
5./etc/profile 文件中添加如下内容
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
6.使用/etc/profile文件生效
source /etc/profile
7.禁用使用Transparent HugePages(启用Transparent HugePages,可能会导致造成内存在运行时的延迟分配，Oracle官方建议使用标准的HugePages)
查看是否启用 如果显示 [always]说明启用了
cat /sys/kernel/mm/transparent_hugepage/enabled
禁用Transparent HugePages,在/etc/grub.conf添加如下内容
echo never > /sys/kernel/mm/transparent_hugepage/enabled
重新启动系统以使更改成为永久更改
6. 创建oracle安装目录
如下目录，根据自己的实际情况可做修改
mkdir -p /data/app/
chown -R oracle:oinstall /data/app/
chmod -R 775 /data/app/
7. 配置oracle用户环境变量
在文件/home/oracle/.bash_profile里添加下面内容(具体值根据实际情况修改)
umask 022
export ORACLE_HOSTNAME=x101
export ORACLE_BASE=/data/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/
export ORACLE_SID=ORCL
export PATH=.:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$ORACLE_HOME/jdk/bin:$PATH
export LC_ALL="en_US"
export LANG="en_US"
export NLS_LANG="AMERICAN_AMERICA.ZHS16GBK"
export NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"
8. 重启下系统
reboot
9. 解压下载好的两个Oracle数据库文件
unzip -q linux.x64_11gR2_database_1of2.zip -d /data
unzip -q linux.x64_11gR2_database_2of2.zip -d /data
mkdir -p /data/etc
cp /data/database/response/* /data/etc/
在/data/etc/db_install.rsp修改以下变量的值
oracle.install.option=INSTALL_DB_SWONLY
DECLINE_SECURITY_UPDATES=true
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/data/app/oracle/inventory
SELECTED_LANGUAGES=en,zh_CN
ORACLE_HOSTNAME=oracledb
ORACLE_HOME=/data/app/oracle/product/11.2.0
ORACLE_BASE=/data/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.isCustomInstall=true
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=dba
10、 开始安装
su - oracle
cd /data/database
./runInstaller -silent -responseFile /data/etc/db_install.rsp -ignorePrereq
安装期间可以使用tail命令监看oracle的安装日志
#日志文件名称根据自己的实际执行时间变更
tail -f /data/app/oracle/inventory/logs/installActions2019-01-02_06-03-30PM.log
安装完成后有如下提示，如果有类似如下提示，说明安装完成
The following configuration scripts need to be executed as the "root" user.
#!/bin/sh
#Root scripts to run
/u01/app/oraInventory/orainstRoot.sh
/u01/app/oracle/product/11.2.0/db_1/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.
11、使用root用户执行脚本
su - root
sh /data/app/oracle/inventory/orainstRoot.sh
sh /data/app/oracle/product/11.2.0/root.sh
12. 配置监听程序
su - oracle
netca /silent /responsefile /data/etc/netca.rsp
#输出结果
[oracle@oracledb ~]$ netca /silent /responsefile /data/etc/netca.rsp
Parsing command line arguments:
Parameter "silent" = true
Parameter "responsefile" = /data/etc/netca.rsp
Done parsing command line arguments.
Oracle Net Services Configuration:
Profile configuration complete.
Oracle Net Listener Startup:
Running Listener Control:
/data/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
查看监听端口
netstat -tnpl | grep 1521
13、静默创建数据库
1.编辑应答文件/data/etc/dbca.rsp
[GENERAL]
RESPONSEFILE_VERSION = "11.2.0"
OPERATION_TYPE = "createDatabase"
[CREATEDATABASE]
GDBNAME = "orcl"
SID = "orcl"
SYSPASSWORD = "oracle"
SYSTEMPASSWORD = "oracle"
SYSMANPASSWORD = "oracle"
DBSNMPPASSWORD = "oracle"
DATAFILEDESTINATION =/data/app/oracle/oradata
RECOVERYAREADESTINATION=/data/app/oracle/fast_recovery_area
CHARACTERSET = "AL32UTF8"
TOTALMEMORY = "1638"
2.执行静默建库
su - oracle
dbca -silent -responseFile /data/etc/dbca.rsp
执行过程如下
[oracle@oracledb ~]$ dbca -silent -responseFile /data/etc/dbca.rsp
Copying database files
1% complete
3% complete
11% complete
18% complete
26% complete
37% complete
Creating and starting Oracle instance
40% complete
45% complete
50% complete
55% complete
56% complete
60% complete
62% complete

70% complete
73% complete
85% complete
96% complete
100% complete
Look at the log file "/data/app/oracle/cfgtoollogs/dbca/orcl/orcl.log" for further details.
3.查看进程
ps -ef | grep ora_ | grep -v grep
# 执行结果
[oracle@oracledb ~]$ ps -ef | grep ora_ | grep -v grep
oracle 19304 1 0 18:33 ? 00:00:00 ora_pmon_orcl

oracle 19398 1 0 18:34 ? 00:00:00 ora_q001_orcl
4.查看监听状态
$ lsnrctl status
#结果
[oracle@oracledb ~]$ lsnrctl status

14、至此数据库就安装成功了，下面我们登录下数据库
su - oracle
sqlplus / as sysdba
select status from v$instance;
执行select时，全出现以下情况
SQL> select status from v$instance;
select status from v$instance

15、设置Oracle开机启动
手动单独启动监听服务 su - oracle
lsnrctl start
修改/data/app/oracle/product/11.2.0/bin/dbstart
ORACLE_HOME_LISTNER=$ORACLE_HOME
修改/data/app/oracle/product/11.2.0/bin/dbshut
ORACLE_HOME_LISTNER=$ORACLE_HOME
修改vi /etc/oratab
orcl:/data/app/oracle/product/11.2.0:Y
新建文件/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.

. /etc/rc.d/init.d/functions
LOCKFILE=/var/lock/subsys/oracle
ORACLE_HOME=/data/app/oracle/product/11.2.0
ORACLE_USER=oracle
case "$1" in
'start')
if [ -f $LOCKFILE ]; then
echo $0 already running.
exit 1
fi
echo -n $"Starting Oracle Database:"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/lsnrctl start"

su - $ORACLE_USER -c "fuser -k /data/app/oracle/product/11.2.0/dbs/lkORCL"
touch $LOCKFILE
;;
'stop')
if [ ! -f $LOCKFILE ]; then
echo $0 already stopping.
exit 1
fi
echo -n $"Stopping Oracle Database:"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/lsnrctl stop"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/dbshut"

rm -f $LOCKFILE
;;
'restart')
$0 stop
$0 start
;;
'status')
if [ -f $LOCKFILE ]; then
echo $0 started.
else
echo $0 stopped.
fi
;;
*)
echo "Usage: $0 [start|stop|status]"
exit 1
esac
exit 0
给/etc/init.d/oracle添加执行权限
chmod +x /etc/init.d/oracle
开机启动oracle
systemctl enable oracle
或chkconfig oracle on
给启动文件加权限
cd /data/app/oracle/product/11.2.0/bin/
chmod 6751 oracle
cd /var/tmp
chown -R oracle:oinstall .oracle
16、防火墙配置放开Oracle的端口
firewall-cmd --zone=public --add-port=1521/tcp --permanent
firewall-cmd --reload
