亲自测试，安装过多台，均未发现问题
参考官网文档：
https://docs.oracle.com/cd/E11882_01/install.112/e24326/toc.htm#BHCFACHG
安装基础依赖包
yum 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
添加用户
groupadd -g 200 oinstall
groupadd -g 201 dba
groupadd -g 202 oper
useradd -g oinstall -u 440 -G dba oracle
修改内核参数
vim /etc/sysctl.conf
# sysctl settings are defined through files in
# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.
#
# Vendors settings live in /usr/lib/sysctl.d/.
# To override a whole file, create a new file with the same in
# /etc/sysctl.d/ and put new settings there. To override
# only specific settings, add a file with a lexically later
# name in /etc/sysctl.d/ and put new settings there.
#
# For more information, see sysctl.conf(5) and sysctl.d(5).

net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
重新加载内核参数
/sbin/sysctl -p
创建安装目录
mkdir -p /opt/oracle
chown -R oracle.oinstall /opt/oracle
chmod -R 755 /opt/oracle
修改登陆限制
vi /etc/pam.d/login
...
# oracle
session required /lib64/security/pam_limits.so
session required pam_limits.so
修改用户环境变量
vi /home/oracle/.bash_profile
# User specific environment and startup programs
ORACLE_BASE=/opt/oracle
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db
ORACLE_SID=orcl
PATH=$PATH:$ORACLE_HOME/bin:$HOME/.local/bin:$HOME/bin
export ORACLE_BASE ORACLE_HOME ORACLE_SID
export PATH
解压oracle安装包
yum install zip unzip
#按顺序解压1和2
unzip linux*.zip
移动安装包到oracle家目录下
mv database /home/oracle/
chown -R oracle.oinstall /home/oracle
修改配置文件的以下配置项 database/response/db_install.rsp
oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v11_2_0
oracle.install.option=INSTALL_DB_SWONLY
###这个hostname自己看下自己机器的
ORACLE_HOSTNAME=ORACLE_HOSTNAME
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/opt/oracle/oraInventory
SELECTED_LANGUAGES=en,zh_CN
ORACLE_HOME=/opt/oracle/product/11.2.0/db
ORACLE_BASE=/opt/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.config.starterdb.type=GENERAL_PURPOSE
oracle.install.db.config.starterdb.globalDBName=orcl
oracle.install.db.config.starterdb.SID=orcl
###这个配置是解决中文乱码
oracle.install.db.config.starterdb.characterSet=AL32UTF8
oracle.install.db.config.starterdb.memoryOption=true
oracle.install.db.config.starterdb.installExampleSchemas=false
oracle.install.db.config.starterdb.enableSecuritySettings=true

oracle.install.db.config.starterdb.control=DB_CONTROL
oracle.install.db.config.starterdb.dbcontrol.enableEmailNotification=false
oracle.install.db.config.starterdb.automatedBackup.enable=false
静默安装。这里需要切换到oracle账户下进行
su - oracle
/home/oracle/database/runInstaller -silent -ignorePrereq -ignoreSysPrereqs -responseFile /home/oracle/database/response/db_install.rsp
初始化脚本，这里要切换回root用户
/opt/oracle/oraInventory/orainstRoot.sh
/opt/oracle/product/11.2.0/db/root.sh
安装监听，这里也需要切到oracle账户
su - oracle
/opt/oracle/product/11.2.0/db/bin/netca /silent /responseFile /home/oracle/database/response/netca.rsp
修改dbca.rsp（需要在配置中设置密码，否则安装会出现清屏状况，影响操作）
SYSPASSWORD = "oracle"
SYSTEMPASSWORD = "oracle"
SYSMANPASSWORD = "oracle"
DBSNMPPASSWORD = "oracle"
dbca.rsp其他配置项：
RESPONSEFILE_VERSION = "11.2.0"
OPERATION_TYPE = "createDatabase"
GDBNAME = "orcl"
SID = "orcl"
TEMPLATENAME = "General_Purpose.dbc"
NATIONALCHARACTERSET= "UTF8"
SOURCEDB = "myhost:1521:orcl"
SOURCEDB = "orcl"
SOURCEDB = "orcl"
DB_UNIQUE_NAME = "orcl"
INSTANCENAME = "orcl"
SYSDBAUSERNAME = "sys"
静默安装数据库
/opt/oracle/product/11.2.0/db/bin/dbca -silent -responseFile /home/oracle/database/response/dbca.rsp
安装完成，最后测试即可
