Exadata是Oracle软硬结合的一体机，通过自己的机子不可能完全模拟出来，这里搭建的虚拟机只是一个简单的、可以供我们学习Exadata的环境。

最简单可以模拟的Exadata虚拟机需要两个节点，CELL节点和DB节点。

首先说一下CELL节点安装介质：

OEL5.6-x86-64

cell-11.2.3.3.1_LINUX.X64

这两个在https://edelivery.oracle.com/ 可以下载的到

下面是具体安装步骤：

关闭UEK，否则启动cellsrv会报错：

[root@CELL ~]# vi /etc/grub.conf

# grub.conf generated by anaconda

#

# Note that you do not have to rerun grub after making changes to this file

# NOTICE: You have a /boot partition. This means that

# all kernel and initrd paths are relative to /boot/, eg.

# root (hd0,0)

# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00

# initrd /initrd-version.img

#boot=/dev/sda

default=1 原本为0 改为1

timeout=5

splashimage=(hd0,0)/grub/splash.xpm.gz

hiddenmenu

。。。。略。。。

重启系统：

[root@CELL ~]# reboot

hosts文件配置如下：

[root@CELL ~]# cat /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost

::1 localhost6.localdomain6 localhost6

192.168.90.151 CELL

网卡配置如下：

[root@CELL ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)

DEVICE=eth0

BOOTPROTO=static

BROADCAST=192.168.90.255

HWADDR=00:0C:29:3D:9A:03

IPADDR=192.168.90.151

IPV6INIT=yes

IPV6_AUTOCONF=yes

NETMASK=255.255.255.0

NETWORK=192.168.90.0

ONBOOT=yes

使用oracle-validated安装一些rpm包

[root@CELL ~]# vi /etc/yum.repos.d/public-yum-el5.repo

[oel5]

name = Enterprise Linux 5.6 DVD

baseurl=file:///mnt/Server/

gpgcheck=0

enabled=1

[root@CELL ~]# mount /dev/cdrom /mnt

mount: block device /dev/cdrom is write-protected, mounting read-only

[root@CELL ~]# yum install oracle-validated

Loaded plugins: rhnplugin, security

ULN support will be disabled.
