1 准备条件
1.1 硬件版本
家用PC机一台，硬盘空间150G以上，内存8G以上。每个虚拟机（理论要求）配置4G内存
1.2 软件版本
虚拟化软件：VMware Workstation8 以上版本操作系统： CentOS6.5/REHL6.5/OEL6.5以上
数据库版本：12C
ASMlib下载：
http://www.oracle.com/technetwork/server-storage/linux/asmlib/index-101839.html
2 网络规划
家中机器的IP地址都由无线路由DHCP统一分配IP，网断192.168.1.*。但是考虑到虚拟机后续接入的便利性，故将IP固定，分配IP地址如下。主机名 PUB Private ip VIP SCANIP 域名
slave1 192.168.1.201 10.10.0.201 192.168.1.211 192.168.1.220 hoptoad.com
slave2 192.168.1.202 10.10.0.202 192.168.1.212
slave2 192.168.1.203 10.10.0.203 192.168.1.213
3 创建虚拟机
虚拟机配置：CPU数量2X2内存：2G
硬盘：30G
网卡： 2个（一个使用VMNET0，一个使用Bridge）
安装操作系统。
3.1 克隆虚拟机
安装完一个虚拟机操作系统后，可以直接进行clone.3.1.1 修改udev文件
克隆完毕后需要修改/etc/udev/rules.d/70-persistent-net.rules，删除
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:42:b0:b9", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
修改第二行NAME=”eth1” 为 NAME=”eth0”
这样克隆的虚拟机网卡看到的都是eth0开头。
也可以直接删除这个文件后重启。
3.1.2 修改主机名字
修改/etc/sysconfig/network文件中HOSTNAME=rac1防止各个机器的主机名字一样。
4 共享存储实现
4.1 其中一个VM添加磁盘
右键其中任何一个虚拟机->setting…->add…->HardDisk->Next->create a new virtual disk –》勾选independent->next->SCSI选中->next->大小设置10G->next->选择single file->设置文件名字->设置文件存放路径->advanced…->选择虚拟设备节点scsi 1:0->确定。同样再增加2个虚拟设备节点分别是1G scsi 1:1，scsi 1:2的磁盘。
4.2 设置磁盘共享
找到该虚拟机镜像存放的路径，本人放在D盘。找到其中的.vmx后缀文件，编辑。加入如下变量。(关机设置)
disk.locking = "FALSE"
disk.EnableUUID ="true"
diskLib.dataCacheMaxSize = "0"
scsi1.sharedBus="virtual"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.DataCacheMinReadAheadSize = "0"
diskLib.datacachepagesize=4096
diskLib.maxunsyncedwrites=”0”
scsi1:0.deviceType="disk"
scsi1:1.deviceType="disk"
注意所有虚拟机都需要设置该变量。
4.3 其他虚拟机添加磁盘
右键其中任何一个虚拟机->setting…->add…->HardDisk->Next->using an existing virtual disk->next->选中之前创建的磁盘->选择虚拟设备节点scsi 1:0->确定同样再增加2个已经存在的磁盘分别是1G scsi 1:1，scsi 1:2的磁盘。
同样处理所有其他节点的虚拟机。
完毕后重启，所有虚拟机可以看到3块共享的磁盘。
通过执行命令fdisk –l查看。
4.4 如果使用系统的ASM配置
命令如下：systemctl enable oracleasm.service（Redhat 7之后）
/etc/init.d/oracleasm configure 或/etc/init.d/oracleasm configure –i
配置用户grid, asmdba
配置ASM盘 （错误日志 /var/log/oracleasm）
注：记得关闭SELINUX
如果没有没有UUID，继续格式化一下,如：mkfs.ext4 /dev/sdb
5 系统环境预准备
5.1 搭建YUM环境
5.1.1 传入操作系统镜像到各个虚拟机中
5.1.2 编辑/etc/yum.repos.d/rhel-source.repo
如下：
[rhel-source]
name=Red Hat Enterprise Linux $releasever - $basearch - Source
baseurl=file:///mnt
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
5.1.3 执行如下命令，挂载光盘
[root@slave1 ~]# mount -o loop Red\ Hat\ Enterprise\ 6.5\ x86_64.iso /mnt5.1.4 同样每个虚拟机都配置YUM环境
完毕，这样可以通过本地YUM源来安装相关RPM包。5.2 解压数据库软件包
执行加压命令如下：[root@slave1 ~]# unzip linuxamd64_12c_database_1of2.zip
同理解压所有压缩包。
5.3 安装数据库必备包

5.3.3 其他包安装
安装oracleasmlib 包启动oracleasm
#service oracleasm start
红帽7.0后启动
#systemctl start oracleasm
安装cvuqdisk程序包（grid压缩包解压得到）
6 网络配置
根据网络规划配置网络地址。配置网络命令
#setup 弹出配置对话框即可进行配置。
也可以编辑/etc/sysconfig/network-scripts/ifcfg-eth0 文件进行配置。
（这里是针对REHL的，SUSE的话略有不同）
6.1 编辑/etc/hosts文件
每个虚拟机的/etc/hosts文件。如下：
192.168.1.201 slave1.hoptoad.com slave1
192.168.1.202 slave2.hoptoad.com slave2
192.168.1.203 slave3.hoptoad.com slave3
#Private IP
10.10.0.201 slave1-priv.hoptoad.com slave1-priv
10.10.0.202 slave2-priv.hoptoad.com slave2-priv
10.10.0.203 slave3-priv.hoptoad.com slave3-priv
#Vip
192.168.1.211 slave1-vip.hoptoad.com slave1-vip
192.168.1.212 slave2-vip.hoptoad.com slave2-vip
192.168.1.213 slave3-vip.hoptoad.com slave3-vip
#scanip
192.168.1.220 rac-scan.hoptoad.com rac-scan
7 系统参数设置
编辑/etc/sysctl.conf 文件，增加如下内容fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax=913516544
kernel.panic_on_oops=1
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 = 1048586
执行sysctl –p
使生效
编辑/etc/sysconfig/network
加入NOZEROCONF=yes

10.3 重新启动UDEV
/sbin/start_udev10.4 DNS配置
10.4.1 安装DNS包
#yum install bind开启启动
#chkconfig named on
Redhat 7之后执行
#systemctl enable named.service
10.4.2 配置/etc/named.conf
如下：
options {
directory "/var/named"; // Base directory for named
allow-transfer {"none";}; // Slave serves that can pull zone transfer. Ban everyone by
};
zone "." IN {
type hint;
file "named.ca";
};
include "/etc/named.rfc1912.zones";
zone "1.168.192.IN-ADDR.ARPA." IN { // Reverse zone.
type master;
notify no;
file "192.168.1.zone";
};
zone "0.10.10.IN-ADDR.ARPA." IN { // Reverse zone.
type master;
notify no;
file "10.10.0.zone";
};
zone "hoptoad.com." IN {
type master;
notify no;
file "hoptoad.com.zone";
};
10.4.3 配置正反向文件

10.4.5 检测DNS
确保每个主机名都要能解析IP 地址
[root@rac1 named]# nslookup rac1.hoptoad.com
11 安装前配置检查
安装GRID包中的 cvuqdisk-1.0.9-1.rpm RPM包(各个节点都安装)执行如下命令：
11.1 检查一
./runcluvfy.sh stage -post hwos -n slave1,slave2,slave3 -verbose./runcluvfy.sh stage -post hwos -n rac1,rac2,rac3 -verbose
./runcluvfy.sh stage -post hwos -n rac1,rac2 -verbose

15.1 VMWAR Workstation网桥
VMware虚拟网卡使用网络地址规划表虚拟网卡名称 使用网段 子网掩码
VMnet1（即host网卡） 192.168.10.0 255.255.255.0
VMnet2（默认没有安装） 192.168.20.0 255.255.255.0
VMnet3（默认没有安装） 192.168.30.0 255.255.255.0
VMnet4（默认没有安装） 192.168.40.0 255.255.255.0
VMnet5（默认没有安装） 192.168.50.0 255.255.255.0
VMnet6（默认没有安装） 192.168.60.0 255.255.255.0
VMnet7（默认没有安装） 192.168.70.0 255.255.255.0
VMnet8（即NAT网卡） 192.168.80.0 255.255.255.0
地址只是为了统一和方便，读者可以根据自己的爱好进行规划。另外，在做实验的过程中，这个地址是可以随时修改的。
使用VMware Workstation创建虚拟机时，创建的虚拟机中可以包括网卡。根据需要选择使用何种虚拟网卡，从而决定连接到那个虚拟交换机。在VMware Workstation中，默认有3个虚拟交换机，分别是VMnet0（使用桥接网络）、VMnet1（仅主机网络）和VMnet8（NAT网络），也可以根据需要添加VMnet2～VMnet7和VMnet9等7个虚拟机交换机。
15.2 解决SQLPLUS下左右问题
