操作系统Centos6.4：

安装前网络规划：

1、使用之前已经配置好的公网bond0的ip通过crt登陆主机

2、编辑eth2的配置文件

[root@rac1 network-scripts]# vi ifcfg-eth2

DEVICE=eth2 HWADDR=08:00:27:18:29:48 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=none IPV6INIT=no USERCTL=no IPADDR=10.0.10.1 NETMASK=255.255.255.0 GATEWAY=192.168.0.1

3、编辑eth3的配置文件

[plain] view plain copy print?

<code class="language-plain">[root@rac1 network-scripts]# vi ifcfg-eth3
DEVICE=eth3
HWADDR=08:00:27:59:1e:79
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
IPADDR=10.0.10.2
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
IPV6INIT=no
USERCTL=no</code>

[root@rac1 network-scripts]# vi ifcfg-eth3
DEVICE=eth3
HWADDR=08:00:27:59:1e:79
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
IPADDR=10.0.10.2
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
IPV6INIT=no
USERCTL=no

4、bootproto=no表示手动设置ip地址。onboot=yes表示开机自动加载网卡。

注意设置ipaddr、geteway、netmask选项。

5、设置完成重启网络服务。

[root@rac1 network-scripts]# service network restart
正在关闭接口 bond0： [确定]
正在关闭接口 eth2： [确定]
正在关闭接口 eth3： [确定]
关闭环回接口： [确定]
弹出环回接口： [确定]
弹出界面 bond0： [确定]
弹出界面 eth2： [确定]
弹出界面 eth3： [确定]

6、ifconfig查看eth2和eth3网卡IP地址是否正确；

[root@rac1 network-scripts]# ifconfig

按照上面配置的私网ip，因为ip在一个网段，所以会检查出错误

详细错误说明如下：

如果遇到上面的错误，你可以选择忽略。如果不想忽略，也可以选择把两块私网ip配置成不同网段的ip地址。比如eth2配置成10.0.10.1，eth3配置成10.0.11.2就可以了。

7、本地ping

[root@rac1 network-scripts]# ping 10.0.10.1
PING 10.0.10.1 (10.0.10.1) 56(84) bytes of data.
64 bytes from 10.0.10.1: icmp_seq=1 ttl=64 time=0.024 ms
64 bytes from 10.0.10.1: icmp_seq=2 ttl=64 time=0.030 ms
^C

rtt min/avg/max/mdev = 0.023/0.031/0.038/0.006 ms
[root@rac1 network-scripts]#

8、ok，私网配置没问题。

9、确认该节点主机名是rac1

vi /etc/sysconfig/network

NETWORKDING=yes

HOSTNAME=rac1

NOZEROCONF=yes

命令：

hostname rac1

更改主机名立即生效

10、配置节点rac1使用dns服务器进行解析

vi /etc/resolv.conf

options attempts: 2

options timeout: 1

search taryartar.com

nameserver 192.168.0.88

nameserver 192.168.0.1

nameserver 8.8.8.8

11、验证dns是否能够生效

正向解析：

host rac1

nslookup rac1

反向解析：

nslookup 192.168.0.51

都没问题。

[root@rac1 network-scripts]# nslookup rac1
Server: 192.168.0.88
Address: 192.168.0.88#53
Name: rac1.taryartar.com
Address: 192.168.0.51
[root@rac1 network-scripts]# nslookup 192.168.0.51
Server: 192.168.0.88
Address: 192.168.0.88#53
51.0.168.192.in-addr.arpa name = rac1.taryartar.com.
[root@rac1 network-scripts]# host rac1
rac1.taryartar.com has address 192.168.0.51
[root@rac1 network-scripts]#

12、创建用户和用户组

[root@rac1 network-scripts]# groupadd -g 1000 oinstall
[root@rac1 network-scripts]# groupadd -g 1031 dba
[root@rac1 network-scripts]# groupadd -g 1032 asmdba
[root@rac1 network-scripts]# useradd -u 1101 -g oinstall -G dba,asmdba oracle
[root@rac1 network-scripts]# useradd -u 1100 -g oinstall -G asmdba grid
[root@rac1 network-scripts]# mkdir -p /taryartar/12c/grid_base
[root@rac1 network-scripts]# mkdir -p /taryartar/12c/grid_home
[root@rac1 network-scripts]# mkdir -p /taryartar/12c/db_base/db_home
[root@rac1 network-scripts]# chown -R grid:oinstall /taryartar/12c/grid_base
[root@rac1 network-scripts]# chown -R grid:oinstall /taryartar/12c/grid_home
[root@rac1 network-scripts]# chown -R oracle:oinstall /taryartar/12c/db_base
[root@rac1 network-scripts]# chmod -R 775 /taryartar/12c/db_base
[root@rac1 network-scripts]# chmod -R 775 /taryartar/12c/grid_base
[root@rac1 network-scripts]# chmod -R 775 /taryartar/12c/grid_home
[root@rac1 network-scripts]#

13、系统配置

Uname -a

Lsb_release

Each system must meet the following minimum memory requirements:

At least 4 GB of RAM for Oracle Grid Infrastructure for a Cluster installations, including installations where you plan to install Oracle RAC.

Swap space equivalent to the multiple of the available RAM, as indicated in the following table:

Table 2-1 Swap Space Required for 64-bit Linux and Linux on System z

Available RAM	Swap Space Required
Between 4 GB and 16 GB	Equal to RAM
More than 16 GB	16 GB of RAM

14、交换分区不够，可以如下扩展

[root@rac1 selinux]# dd if=/dev/zero of=/root/swapfile1 bs=1M count=1024
记录了500+0 的读入
记录了500+0 的写出
524288000字节(524 MB)已复制，1.34808 秒，389 MB/秒
[root@rac1 selinux]# chmod 600 /root/swapfile1
[root@rac1 selinux]# mkswap /root/swapfile1
Setting up swapspace version 1, size = 511996 KiB
no label, UUID=a44009c0-9d5e-4ea5-b9db-f8ae81b16a0b
[root@rac1 selinux]# swapon /root/swapfile1

[root@rac1 selinux]# free -m
total used free shared buffers cached
Mem: 1500 1428 71 0 20 1238
-/+ buffers/cache: 169 1331
Swap: 4007 0 4007

要想下次重启仍然生效，需要写入下面的配置文件

vi /etc/fstab

新增下面一行

/root/swapfile1 swap swap defaults 0 0

15、注意集群安装可能受防火墙和selinux干扰，最好关闭防火墙和selinux，否则出一些某明奇妙的问题排查起来很麻烦

关闭防火墙并关闭自启动

[root@rac1 yum.repos.d]# service iptables stop
iptables：清除防火墙规则：[确定]
iptables：将链设置为政策 ACCEPT：filter [确定]
iptables：正在卸载模块：[确定]
[root@rac1 yum.repos.d]# chkconfig iptables off

16、关闭selinux

[root@rac1 yum.repos.d]# getenforce
Enforcing
[root@rac1 yum.repos.d]# setenforce 0
[root@rac1 yum.repos.d]# getenforce
Permissive

vi /etc/selinux/config

修改SELINUX的值为permissive

SELINUX=permissive

17、关闭ipv6

[root@rac1 selinux]# service ip6tables stop
ip6tables：清除防火墙规则：[确定]
ip6tables：将 chains 设置为 ACCEPT 策略：filter [确定]
：正在卸载模块：[确定]
[root@rac1 selinux]# chkconfig ip6tables off
[root@rac1 selinux]#

18、修改ssh连接配置文件

vi /etc/ssh/sshd_config

新增

LoginGraceTime 0

表示远程连接节点不会被关闭连接。

19、安装rpm包

针对redhat6（同centos6）官网指定安装包如下：

CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlib
export CLASSPATH
export ORACLE_HOSTNAME=rac1.taryartar.com
export DB_UNIQUE_NAME=tar
export CVUQDISK=oinstall
umask 022

使环境变量立即生效：

source .bash_profile

22、修改内核参数

Su - root
Vi /etc/sysctl.conf
先把kernel.shmmax和kernel.shmall
两个注释掉
新增下面一段：

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
#物理内存的50-60%
kernel.shmmax = 1046898278
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

[root@rac1 ssh]# vi /etc/sysctl.conf

# Controls the maximum shared segment size, in bytes
#kernel.shmmax = 68719476736
# Controls the maximum number of shared memory segments, in pages
#kernel.shmall = 4294967296
##add by wufan 2017/10/15
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
#物理内存的50-60%
kernel.shmmax = 1046898278
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

使内核参数立即生效

[root@rac1 ssh]# sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key
error: "net.bridge.bridge-nf-call-iptables" is an unknown key
error: "net.bridge.bridge-nf-call-arptables" is an unknown key
kernel.msgmnb = 65536
kernel.msgmax = 65536
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 1046898278
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

查看内核是否生效

[root@rac1 ssh]# sysctl -a |grep shmmax
kernel.shmmax = 1046898278

23、修改用户资源限制

[root@rac1 ssh]# vi /etc/security/limits.conf

新增如下内容：

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

nproc 最大进程数限制

nofile 最大文件数限制

24、至此，节点1安装前准备就算基本完成，下面需要对节点1重启后检查一遍：

http://blog.csdn.net/kadwf123/article/details/78241445

25、对第一个节点执行导出（需要注意该节点处于停止状态）。

导出后对导出的文件进行导入，然后启动新节点，用crt直接通过节点1的ip进行登录。

26、然后修改主机名和ip

[oracle@rac2 ~]$ vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=rac2

[root@rac2 ~]# hostname rac2

[root@rac2 ~]# hostname
rac2

hostname改成rac2

[root@rac2 ~]# vi /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
IPADDR=192.168.0.52
NETMASK=255.255.255.0
USERCTL=no
BOOTPROTO=none
ONBOOT=yes
GATEWAY=192.168.0.1
IPV6INIT=no
TYPE=Ethernet
#DNS1=192.168.0.1

公网ipaddr改成192.168.0.52，其它保持不变

改第一块私网网卡eth2

[root@rac2 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth2
DEVICE=eth2
HWADDR=08:00:27:18:29:48
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPV6INIT=no
USERCTL=no
IPADDR=10.0.10.3
NETMASK=255.255.255.0
GATEWAY=192.168.0.1

ipaddr改成10.0.10.3，其它保持不变。

改第二块私网网卡eth3

[root@rac2 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth3
DEVICE=eth3
HWADDR=08:00:27:59:1e:79
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
IPADDR=10.0.10.4
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
IPV6INIT=no
USERCTL=no

ipaddr改成10.0.10.4，其它不变。

27、重启网络服务

[root@rac2 ~]# service network restart

重启后需要重新登陆crt建立到新节点ip192.168.0.52的网络连接。

28、登陆后检查rac2的dns是否可用。

[root@rac2 ~]# nslookup rac3
Server: 192.168.0.88
Address: 192.168.0.88#53
Name: rac3.taryartar.com
Address: 192.168.0.53
[root@rac2 ~]# nslookup rac2.taryartar.com
Server: 192.168.0.88
Address: 192.168.0.88#53
Name: rac2.taryartar.com
Address: 192.168.0.52
[root@rac2 ~]# nslookup 192.168.0.54
Server: 192.168.0.88
Address: 192.168.0.88#53
54.0.168.192.in-addr.arpa name = rac4.taryartar.com.
[root@rac2 ~]#

ok,正向反向解析都没问题。

29、修改grid用户环境变量配置

[root@rac2 ~]# su - grid
[grid@rac2 ~]$ vi .bash_profile
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
#add by wufan 2017/1015
export ORACLE_SID=+ASM2
export ORACLE_BASE=/taryartar/12c/grid_base
export ORACLE_HOME=/taryartar/12c/grid_home
export GRID_HOME=$ORACLE_HOME
export ORACLE_TERM=xterm
export TMP=/tmp
export TMPDIR=$TMP
#PATH=$PATH:$HOME/bin
export PATH=/usr/sbin:$PATH:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export ORACLE_HOSTNAME=rac2.taryartar.com
export DB_UNIQUE_NAME=tar
export CVUQDISK_GRP=oinstall
umask 022

只需修改ORACLE_SID和ORACLE_HOSTNAME两个变量值

改完立即生效，执行命令

source .bash_profile

检查更改是否生效：

[grid@rac2 ~]$ env |grep -i oracle_sid
ORACLE_SID=+ASM2
[grid@rac2 ~]$ env|grep -i oracle_hostname
ORACLE_HOSTNAME=rac2.taryartar.com
[grid@rac2 ~]$

30、修改oracle用户环境变量

[root@rac2 ~]# su - oracle
[oracle@rac2 ~]$ vi .bash_profile
PATH=$PATH:$HOME/bin
export PATH
#add by wufan 2017/10/15
export ORACLE_BASE=/taryartar/12c/db_base
export ORACLE_HOME=$ORACLE_BASE/db_home
export ORACLE_SID=tar2
export ORACLE_OWNER=oracle
export ORACLE_TERM=vt100
export PATH=$PATH:$ORACLE_HOME/bin
export PATH=$ORACLE_HOME/Apache/Apache/bin:$PATH
export BASE_PATH=/usr/sbin:$PATH:$BASE_PATH
export PATH=$BASE_PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/usr/local/lib
export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlib
export CLASSPATH
export ORACLE_HOSTNAME=rac2.taryartar.com
export DB_UNIQUE_NAME=tar
export CVUQDISK=oinstall

只需修改ORACLE_SID和ORACLE_HOSTNAME两个变量

改完立即生效，执行命令

source .bash_profile

检查更改是否生效：

[oracle@rac2 ~]$ env|grep -i oracle_sid
ORACLE_SID=tar2
[oracle@rac2 ~]$ env|grep -i oracle_hostname
ORACLE_HOSTNAME=rac2.taryartar.com
[oracle@rac2 ~]$

31、至此，第二个节点更改完成。

32、按照上述方法建立第3-4个节点。

33、下面配置共享存储

一共七块盘，两块10g，外加5块各2g。

34、创建磁盘virtualbox命令创建：

创建第一块磁盘：

E:\Program Files\Oracle\VirtualBox\VBoxManage createhd --filename E:\实验环境\12CRAC\V_SHARES\taryartar1.vdi --size 12288 --format VDI --variant Fixed

如果你跟我一样，virtualbox安装目录有空格Program Files，那么可能遇到命令不存在的问题。为了方便，我直接把virtual安装目录直接配置到环境变量PATH中。

这样就可以直接执行命令了。

好了成功了。创建剩下的六块盘，附上脚本。

VBoxManage createhd --filename E:\实验环境\12CRAC\V_SHARES\taryartar1.vdi --size 12288 --format VDI --variant Fixed
VBoxManage createhd --filename E:\实验环境\12CRAC\V_SHARES\taryartar2.vdi --size 12288 --format VDI --variant Fixed
VBoxManage createhd --filename E:\实验环境\12CRAC\V_SHARES\taryartar3.vdi --size 2048 --format VDI --variant Fixed
VBoxManage createhd --filename E:\实验环境\12CRAC\V_SHARES\taryartar4.vdi --size 2048 --format VDI --variant Fixed
VBoxManage createhd --filename E:\实验环境\12CRAC\V_SHARES\taryartar5.vdi --size 2048 --format VDI --variant Fixed
VBoxManage createhd --filename E:\实验环境\12CRAC\V_SHARES\taryartar6.vdi --size 2048 --format VDI --variant Fixed
VBoxManage createhd --filename E:\实验环境\12CRAC\V_SHARES\taryartar7.vdi --size 2048 --format VDI --variant Fixed

命令说明:

VBoxManage 是virtualbox安装目录中的命令，VBoxManage.exe可执行文件。

--filename指定需要创建的磁盘的文件位置和名字。

--size指定创建的磁盘大小，单位M。

--format指定磁盘的格式。

35、创建磁盘完成后，需要连接到虚拟机。

在连接到虚拟机前，需要先关闭虚拟机。

连接第一块磁盘到虚拟机rac1-12c，命令如下：

VBoxManage storageattach rac1-12c --storagectl "SATA" --port 4 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar1.vdi --mtype shareable

图中虚拟机名称：

端口号指的是：

VBoxManage storageattach rac1-12c --storagectl "SATA" --port 4 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar1.vdi --mtype shareable
VBoxManage storageattach rac1-12c --storagectl "SATA" --port 5 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar2.vdi --mtype shareable
VBoxManage storageattach rac1-12c --storagectl "SATA" --port 6 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar3.vdi --mtype shareable
VBoxManage storageattach rac1-12c --storagectl "SATA" --port 7 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar4.vdi --mtype shareable
VBoxManage storageattach rac1-12c --storagectl "SATA" --port 8 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar5.vdi --mtype shareable
VBoxManage storageattach rac1-12c --storagectl "SATA" --port 9 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar6.vdi --mtype shareable
VBoxManage storageattach rac1-12c --storagectl "SATA" --port 10 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar7.vdi --mtype shareable

将7块磁盘全部连接至rac1-12c完成后，在图形界面看到如下：

36、连接完成后，需要把7块磁盘改成共享磁盘属性。

VBoxManage modifyhd E:\实验环境\12CRAC\V_SHARES\taryartar1.vdi --type shareable
VBoxManage modifyhd E:\实验环境\12CRAC\V_SHARES\taryartar2.vdi --type shareable
VBoxManage modifyhd E:\实验环境\12CRAC\V_SHARES\taryartar3.vdi --type shareable
VBoxManage modifyhd E:\实验环境\12CRAC\V_SHARES\taryartar4.vdi --type shareable
VBoxManage modifyhd E:\实验环境\12CRAC\V_SHARES\taryartar5.vdi --type shareable
VBoxManage modifyhd E:\实验环境\12CRAC\V_SHARES\taryartar6.vdi --type shareable
VBoxManage modifyhd E:\实验环境\12CRAC\V_SHARES\taryartar7.vdi --type shareable

执行完成后，在把7块盘都连接到另外3台虚拟机

37、脚本如下：

VBoxManage storageattach rac2-12c --storagectl "SATA" --port 4 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar1.vdi --mtype shareable
VBoxManage storageattach rac2-12c --storagectl "SATA" --port 5 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar2.vdi --mtype shareable
VBoxManage storageattach rac2-12c --storagectl "SATA" --port 6 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar3.vdi --mtype shareable
VBoxManage storageattach rac2-12c --storagectl "SATA" --port 7 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar4.vdi --mtype shareable
VBoxManage storageattach rac2-12c --storagectl "SATA" --port 8 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar5.vdi --mtype shareable
VBoxManage storageattach rac2-12c --storagectl "SATA" --port 9 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar6.vdi --mtype shareable
VBoxManage storageattach rac2-12c --storagectl "SATA" --port 10 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar7.vdi --mtype shareable
VBoxManage storageattach rac3-12c --storagectl "SATA" --port 4 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar1.vdi --mtype shareable
VBoxManage storageattach rac3-12c --storagectl "SATA" --port 5 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar2.vdi --mtype shareable
VBoxManage storageattach rac3-12c --storagectl "SATA" --port 6 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar3.vdi --mtype shareable
VBoxManage storageattach rac3-12c --storagectl "SATA" --port 7 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar4.vdi --mtype shareable
VBoxManage storageattach rac3-12c --storagectl "SATA" --port 8 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar5.vdi --mtype shareable
VBoxManage storageattach rac3-12c --storagectl "SATA" --port 9 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar6.vdi --mtype shareable
VBoxManage storageattach rac3-12c --storagectl "SATA" --port 10 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar7.vdi --mtype shareable
VBoxManage storageattach rac4-12c --storagectl "SATA" --port 4 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar1.vdi --mtype shareable
VBoxManage storageattach rac4-12c --storagectl "SATA" --port 5 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar2.vdi --mtype shareable
VBoxManage storageattach rac4-12c --storagectl "SATA" --port 6 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar3.vdi --mtype shareable
VBoxManage storageattach rac4-12c --storagectl "SATA" --port 7 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar4.vdi --mtype shareable
VBoxManage storageattach rac4-12c --storagectl "SATA" --port 8 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar5.vdi --mtype shareable
VBoxManage storageattach rac4-12c --storagectl "SATA" --port 9 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar6.vdi --mtype shareable
VBoxManage storageattach rac4-12c --storagectl "SATA" --port 10 --device 0 --type hdd --medium E:\实验环境\12CRAC\V_SHARES\taryartar7.vdi --mtype shareable

38、共享存储添加完成，启动4台虚拟机，然后用crt登陆。

使用fdisk -l |grep Di查看每台主机的硬盘。

[root@rac1 ~]# fdisk -l|grep Di
Disk /dev/sda: 32.2 GB, 32212254720 bytes

Disk /dev/mapper/vg_rac1-lv_swap: 3154 MB, 3154116608 bytes
Disk identifier: 0x00000000

四台虚拟机都显示如上，表示一切正常。

sda是虚拟机本地普通磁盘。从sd[b-h]是新添加的磁盘。其中sd[b-c]是两块10g的共享盘，后面5块sd[d-h]是2g的共享盘。

39、对7块共享盘进行分区，每个磁盘只分一个区。注意共享盘分区只需要在一个节点上做就可以了，做完其它节点就能看到新的分区。

在节点rac1上进行分区操作。

如下：

http://blog.csdn.net/kadwf123/article/details/78244863

分区完成后，在所有的节点执行fdisk -l

可以看到sd[b-h]都已经增加了一个分区了，如下我在节点1下分区，我截取了节点2看到的分区情况：

显示如上，说明共享磁盘和分区没问题。

40、配置裸设备

查看得到分区的名字

每个节点都进入到下面的目录：

cd /etc/udev/rules.d

然后创建一个规则文件，后缀一定要是.rules：

vi 99-ASM.rules

写入如下内容：

ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sdc1", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdd1", RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", KERNEL=="sde1", RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add", KERNEL=="sdf1", RUN+="/bin/raw /dev/raw/raw5 %N"
ACTION=="add", KERNEL=="sdg1", RUN+="/bin/raw /dev/raw/raw6 %N"
ACTION=="add", KERNEL=="sdh1", RUN+="/bin/raw /dev/raw/raw7 %N"
KERNEL=="raw[1-7]*", OWNER="grid", GROUP="asmdba", MODE="775"

[root@rac1 rules.d]# vi 99-ASM.rules
ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sdc1", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdd1", RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", KERNEL=="sde1", RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add", KERNEL=="sdf1", RUN+="/bin/raw /dev/raw/raw5 %N"
ACTION=="add", KERNEL=="sdg1", RUN+="/bin/raw /dev/raw/raw6 %N"
ACTION=="add", KERNEL=="sdh1", RUN+="/bin/raw /dev/raw/raw7 %N"
KERNEL=="raw[1-7]*", OWNER="grid", GROUP="asmdba", MODE="775"

41、然后启动udev，四个节点都需要执行下面的命令，最好一个个执行。

下面是四个节点下启动的情况：

[root@rac1 rules.d]# start_udev
正在启动 udev：[确定]
[root@rac1 rules.d]#

[root@rac2 rules.d]# start_udev
正在启动 udev：[确定]
[root@rac2 rules.d]#

[root@rac3 rules.d]# start_udev
正在启动 udev：[确定]
[root@rac3 rules.d]#

[root@rac4 rules.d]# start_udev
正在启动 udev：[确定]
[root@rac4 rules.d]#

都启动成功后，可以看下四个节点的裸设备：

我这边发现只有节点1能看到raw[1-7]，其它三个节点只能看到rawctl：

查看另外三个节点中的随便一台日志

view /var/log/messages

找到udev关键字，并且在刚才启动的时间的日志。

发现报如下错误：
