1.如果是刚安装的系统，需要检查依赖包安装

rpm -q binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc-2.17 glibc-common glibc-devel glibc-headers ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel

2.安装依赖包

如果yum安装较慢建议切换阿里yum源

yum源切换

先安装wget命令 
yum install wget -y   #wget命令就是在线下载一个url的静态资源

再执行
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

注：切换之前建议先备份 /etc/yum.repos.d 中的文件

yum install compat-libstdc++-33 -y
yum install elfutils-libelf-devel -y
yum install gcc-c++ -y
yum install glibc-* -y
yum install ksh -y
yum install libaio -y
yum install libaio-devel -y
yum install libstdc++-devel -y
yum install unixODBC -y
yum install unixODBC-devel -y

汇总
yum install compat-libstdc++-33 elfutils-libelf-devel gcc* glibc-* ksh libaio libaio-devel libstdc++-devel unixODBC unixODBC-devel sysstat -y

3.创建需要的用户和用户组

groupadd oinstall
groupadd dba
groupadd asmadmin
groupadd asmdba
useradd -g oinstall -G dba,asmdba oracle -d /home/oracle
passwd oracle

4.修改linux内核参数并关闭selinux、防火墙

vim /etc/sysctl.conf  增加或者修改

具体参数参考如下：

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 8388608
kernel.shmmax = 34359738368
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

关闭selinux
vim /etc/selinux/config
设置SELINUX=disabled

关闭防火墙
systemctl stop firewalld

5.修改/etc/security/limits.conf文件、/etc/pam.d/login文件、/etc/profile文件

vim /etc/security/limits.conf

添加以下设置：

oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240

修改/etc/pam.d/login文件

vim /etc/pam.d/login

添加以下内容

session  required   /lib64/security/pam_limits.so
session  required   pam_limits.so

修改/etc/profile文件

 vim /etc/profile

添加以下配置

if [ $USER = "oracle" ]; then
  if [ $SHELL = "/bin/ksh" ]; then
   ulimit -p 16384
   ulimit -n 65536
  else
   ulimit -u 16384 -n 65536
  fi
fi

使profile文件生效

source /etc/profile

6.创建数据库相关目录并授权、修改/etc/oraInst.loc文件

注：如果没有下载数据库安装包，以下提供下载链接

oracle11g数据库下载地址

mkdir -p /u01/app/
chown -R oracle:oinstall /home/oracle  
chmod -R 775 /home/oracle  
chown -R oracle:oinstall /u01/app/ 
chmod -R 775 /u01/app/

添加/etc/oraInst.loc文件并授权

vim /etc/oraInst.loc

inventory_loc=/u01/app/oracle/oraInventory
inst_group=oinstall

授权

chown oracle:oinstall /etc/oraInst.loc
chmod 664 /etc/oraInst.loc

7.切换的oracle用户，并设置用户环境变量

su - oracle

设置如下：

vim ~/.bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_SID=orcl

使其生效

source ~/.bash_profile

8.上传已经下载好的数据库安装包到linux任意目录并解压，我这里解压到的是/home/oracle/目录

unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_database_2of2.zip

9.切换到root用户并授权相关文件

su - root
cd /home/oracle/ 
mkdir etc
cp /home/oracle/database/response/* /home/oracle/etc/
chmod 777 /home/oracle/etc/*.rsp

10.切换到oracle用户，配置数据库安装文件

su - oracle
vim /home/oracle/etc/db_install.rsp

配置如下：

oracle.install.option=INSTALL_DB_SWONLY
ORACLE_HOSTNAME=主机名
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/u01/app/oracle/oraInventory
SELECTED_LANGUAGES=en,zh_CN,zh_TW
ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
ORACLE_BASE=/u01/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.isCustomInstall=false
oracle.install.db.DBA_GROUP=dba
oracle.install.db.OPER_GROUP=oinstall
#这里必须填ture
DECLINE_SECURITY_UPDATES=true

11.执行安装

./runInstaller -silent -force -responseFile /home/oracle/etc/db_install.rsp -ignorePrereq

此处会卡住，安装完成会出现以下情况则安装成功，若未出现可查看日志文件
成功安装

12.安装完成后切换到root用户

su root
执行
sh /u01/app/oracle/product/11.2.0/db_1/root.sh

13.切换成oracle用户配置环境变量

su - oracle
vim ~/.bash_profile

添加配置如下：

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export TNS_ADMIN=$ORACLE_HOME/network/admin
export PATH=.:${PATH}:$HOME/bin:$ORACLE_HOME/bin
export PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/lib
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/oracm/lib
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib
export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/JRE
export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/JRE/lib
export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/jlib
export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib
export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib
export LIBPATH=${CLASSPATH}:$ORACLE_HOME/lib:$ORACLE_HOME/ctx/lib
export ORACLE_OWNER=oracle
export SPFILE_PATH=$ORACLE_HOME/dbs
export ORA_NLS10=$ORACLE_HOME/nls/data

使.bash_profile文件生效

source ~/.bash_profile

14.安装数据库实例，配置dbca.rsp文件

vim /home/oracle/etc/dbca.rsp

配置如下：

GDBNAME = "orcl"
SID = "orcl"
SYSPASSWORD = "oracle"
SYSTEMPASSWORD = "oracle"
SYSMANPASSWORD = "oracle"
DBSNMPPASSWORD = "oracle"
DATAFILEDESTINATION =/u01/app/oracle/oradata
RECOVERYAREADESTINATION=/u01/app/oracle/fast_recovery_area
CHARACTERSET = "ZHS16GBK"
TOTALMEMORY = "1638"

其中TOTALMEMORY = "1638" 为1638MB，物理内存2G*80%。```

15.安装数据库实例

dbca -silent -responseFile /home/oracle/etc/dbca.rsp

出现以下文字则安装成功
数据库实例安装成功
实例进程检查

ps -ef | grep ora_ | grep -v grep

实例进程检查

16.监听配置，切换到oracle用户

su - oracle
配置监听
netca /silent /responsefile /home/oracle/database/response/netca.rsp

监听配置成功后如下：
监听配置
查看监听状态

netstat -tnulp | grep 1521

监听状态
如果出现以下情况
监听状态显示异常
切换到root用户执行以下操作即可

chmod +s /bin/netstat

17.安装完成，使用sqlplus连接测试

sqlplus system/****

成功测试

18.linux下设置oracle开机自启

切换到root用户执行以下操作

vim /u01/app/oracle/product/11.2.0/db_1/bin/dbstart

修改内容

将 ORACLE_HOME_LISTNER=$1 修改为 ORACLE_HOME_LISTNER=$ORACLE_HOME

再执行

vim /u01/app/oracle/product/11.2.0/db_1/bin/dbshut

修改内容

将 ORACLE_HOME_LISTNER=$1 修改为 ORACLE_HOME_LISTNER=$ORACLE_HOME

修改/etc/oratab文件

vim /etc/oratab

修改内容

将 orcl:/u01/app/oracle/product/11.2.0/db_1:N 中最后的 N 改为 Y

切换用户到oracle执行 dbshut 和 dbstart 测试，如下则成功

在这里插入图片描述
在这里插入图片描述

开始添加启动脚本

vim /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=/u01/app/oracle/product/11.2.0/db_1
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 - $ORACLE_USER -c "$ORACLE_HOME/bin/dbstart $ORACLE_HOME"  
   su - $ORACLE_USER -c "$ORACLE_HOME/bin/emctl start dbconsole"  
   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"   
   su - $ORACLE_USER -c "$ORACLE_HOME/bin/emctl stop dbconsole"  
   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

修改文件权限

chmod 755 /etc/init.d/oracle

设置开机启动执行

chkconfig oracle on

查看

chkconfig --list oracle

执行操作测试 service oracle start/stop/restart 如下即可
