redhat7安装Oracle12c数据库过程

一、Linux系统安装前准备

Linux系统版本为

1.调整系统swap分区大小

root用户下

[root@localhost ~]# fdisk /dev/sdb
Welcome to fdisk (util-linux 2.23.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

[root@localhost ~]# mkswap /dev/sdb5
Setting up swapspace version 1, size = 20970492 KiB
no label, UUID=c985adf5-dbba-48e8-803b-cc34bd0c33b1

[root@localhost ~]# vim /etc/fstab 

添加如下：

UUID=c985adf5-dbba-48e8-803b-cc34bd0c33b1 swap swap defaults 0 0

[root@localhost ~]# swapon -a
[root@localhost ~]# df -h

2.配置yum仓库(本地磁盘镜像iso)

[root@localhost ~] vim etc/yum.repos.d/update.repo

[update]

name=update

baseurl=file:///media/cdrom

enabled=1

gpgcheck=0

[root@localhost ~]mkdir /media/cdrom

[root@localhost ~]vim /etc/fstab

/dev/cdrom /media/cdrom iso9660 defaults 0 0

[root@localhost ~]mount -a

3.关闭防火墙和selinux

[root@localhost ~]# vim /etc/selinux/config 

SELINUX=disabled

[root@localhost ~]# systemctl stop iptables.service

二、Oracle安装

1.下载Oracle需要的依赖包

yum -y install gcc gcc-c++ make binutils compat-libstdc++-33 glibc glbic-devel libaio libaio-devel libgcc libstdc++ libstdc+
