1 安装前准备

yum -y install binutils compat-libcap1 compat-libstdc++.i686 compat-libstdc++.x86_64 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc.i686 glibc.x86_64 glibc-devel.i686 glibc-devel.x86_64 ksh libgcc.i686 libgcc.x86_64 libstdc++.i686 libstdc++.x86_64 libstdc++-devel.i686 libstdc++-devel.x86_64 libaio.i686 libaio.x86_64 libaio-devel.i686 libaio-devel.x86_64 libXext libXtst libX11 libXau libxcb libXi make sysstat unixODBC-devel.i686 unixODBC-devel.x86_64 unixODBC.i686 unixODBC.x86_64 compat-libstdc++-33.i686 compat-libstdc++-33.x86_64

关闭selinux以及firewalld

2 设置主机解析：主机名 oracle

10.0.0.2 oracle

3 创建组以及用户

groupadd oinstall

groupadd dba

useradd -g oinstall -G dba oracle /usermod -g oinstall -G dba oracle(有账户重新赋予命令)

passwd oracle

4 修改内核参数

vi /etc/sysctl.d/sysctl.conf

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

sysctl -p

5 系统资源限制配置

vi /etc/security/limits.conf

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

oracle soft stack 10240

6创建数据库文件夹分配组权限

mkdir -p /u01/app/

mkdir -p /u01/app/oracle/product/12.1.0/dbhome_1

chown -R oracle:oinstall /u01/app/

chmod -R 775 /u01/app/

7设置环境变量

ORACLE_BASE=/u01/app

ORACLE_HOME=$ORACLE_BASE/oracle/product/12.1.0/dbhome_1

ORACLE_SID=orcl

LD_LIBRARY_PATH=$ORACLE_HOME/lib;

PATH=$PATH:$ORACLE_HOME/bin:$HOME/bin;

export ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH PATH;

8设置DISPLAY变量(避免vnc连接安装出错)

export DISPLAY=:1

接下来通过vnc图形界面按照自定义安装，不会出现任何错误提示

安装完毕后：

查看是否在监听：

[oracle@oracle ~]$ ps -ef|grep LISTENER

oracle    9976     1  0 Jul13 ?        00:00:00 /u01/app/oracle/product/12.1.0/dbhome_1/bin/tnslsnr LISTENER -inherit

重启数据库dbshut出现错误：

ORACLE_HOME_LISTNER is not SET, unable to auto-stop Oracle Net Listener Usag

将会对应脚本文件更改为：

ORACLE_HOME_LISTNER=$1 修改为 ORACLE_HOME_LISTNER=$ORACLE_HOME
