oracle12C RAC GI + UDEV + ASM 在centos6下安装详细步骤

Centos配置网络yum源：

Centos配置安装vnc客户端和服务端：

Centos配置dns服务器：

Centos公网双网卡绑定bond0

Centos下安装GI前准备详细执行步骤：

Centos下安装oracle12c需要的依赖包详细安装过程：

Centos下安装oracle12c节点1完成后检查过程：

Centos下安装oracle12c四个节点都完成共享磁盘连接后对共享磁盘分区详细过程：

centos6.4 /f文件改了重启网络就自动还原了

 

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?

  1. <code class="language-plain">[root@rac1 network-scripts]# vi ifcfg-eth3  
  2.   
  3. DEVICE=eth3  
  4. HWADDR=08:00:27:59:1e:79  
  5. TYPE=Ethernet  
  6. ONBOOT=yes  
  7. BOOTPROTO=none  
  8. IPADDR=10.0.10.2  
  9. NETMASK=255.255.255.0  
  10. GATEWAY=192.168.0.1  
  11. IPV6INIT=no  
  12. USERCTL=no</code>  
 

  1. [root@rac1 network-scripts]# vi ifcfg-eth3

  2.  

  3. DEVICE=eth3

  4. HWADDR=08:00:27:59:1e:79

  5. TYPE=Ethernet

  6. ONBOOT=yes

  7. BOOTPROTO=none

  8. IPADDR=10.0.10.2

  9. NETMASK=255.255.255.0

  10. GATEWAY=192.168.0.1

  11. IPV6INIT=no

  12. 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。

 

  1. [root@rac1 network-scripts]# service network restart

  2. 正在关闭接口 bond0： [确定]

  3. 正在关闭接口 eth2： [确定]

  4. 正在关闭接口 eth3： [确定]

  5. 关闭环回接口： [确定]

  6. 弹出环回接口： [确定]

  7. 弹出界面 bond0： [确定]

  8. 弹出界面 eth2： [确定]

  9. 弹出界面 eth3： [确定]


6、ifconfig查看eth2和eth3网卡IP地址是否正确；

 

  1. [root@rac1 network-scripts]# ifconfig

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

 

  1. [root@rac1 network-scripts]# ping 10.0.10.1

  2. PING 10.0.10.1 (10.0.10.1) 56(84) bytes of data.

  3. 64 bytes from 10.0.10.1: icmp_seq=1 ttl=64 time=0.024 ms

  4. 64 bytes from 10.0.10.1: icmp_seq=2 ttl=64 time=0.030 ms

  5. ^C

  6. --- 10.0.10.1 ping statistics ---

  7. 2 packets transmitted, 2 received, 0% packet loss, time 1893ms

  8. rtt min/avg/max/mdev = 0.024/0.027/0.030/0.003 ms

  9. [root@rac1 network-scripts]# ping 10.0.10.2

  10. PING 10.0.10.2 (10.0.10.2) 56(84) bytes of data.

  11. 64 bytes from 10.0.10.2: icmp_seq=1 ttl=64 time=0.023 ms

  17. rtt min/avg/max/mdev = 0.023/0.031/0.038/0.006 ms

  18. [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 /f

options attempts: 2

options timeout: 1

search taryartar

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。

 

  1. [root@rac1 network-scripts]# nslookup rac1

  2. Server: 192.168.0.88

  3. Address: 192.168.0.88#53

  4.  

  5. Name: rac1.taryartar

  6. Address: 192.168.0.51

  7.  

  8. [root@rac1 network-scripts]# nslookup 192.168.0.51

  9. Server: 192.168.0.88

  10. Address: 192.168.0.88#53

  11.  

  12. 51.0.168.192.in-addr.arpa name = rac1.taryartar.

  13.  

  14. [root@rac1 network-scripts]# host rac1

  15. rac1.taryartar has address 192.168.0.51

  16. [root@rac1 network-scripts]#

 

12、创建用户和用户组

 

  1. [root@rac1 network-scripts]# groupadd -g 1000 oinstall

  2. [root@rac1 network-scripts]# groupadd -g 1031 dba

  3. [root@rac1 network-scripts]# groupadd -g 1032 asmdba

  4. [root@rac1 network-scripts]# useradd -u 1101 -g oinstall -G dba,asmdba oracle

  5. [root@rac1 network-scripts]# useradd -u 1100 -g oinstall -G asmdba grid

  6. [root@rac1 network-scripts]# mkdir -p /taryartar/12c/grid_base

  7. [root@rac1 network-scripts]# mkdir -p /taryartar/12c/grid_home

  8. [root@rac1 network-scripts]# mkdir -p /taryartar/12c/db_base/db_home

  9. [root@rac1 network-scripts]# chown -R grid:oinstall /taryartar/12c/grid_base

  10. [root@rac1 network-scripts]# chown -R grid:oinstall /taryartar/12c/grid_home

  11. [root@rac1 network-scripts]# chown -R oracle:oinstall /taryartar/12c/db_base

  12. [root@rac1 network-scripts]# chmod -R 775 /taryartar/12c/db_base

  13. [root@rac1 network-scripts]# chmod -R 775 /taryartar/12c/grid_base

  14. [root@rac1 network-scripts]# chmod -R 775 /taryartar/12c/grid_home

  15. [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

 

 

  1. [root@rac1 selinux]# dd if=/dev/zero of=/root/swapfile1 bs=1M count=1024

  2. 记录了500+0 的读入

  3. 记录了500+0 的写出

  4. 524288000字节(524 MB)已复制，1.34808 秒，389 MB/秒

  5. [root@rac1 selinux]# chmod 600 /root/swapfile1

  6. [root@rac1 selinux]# mkswap /root/swapfile1

  7. Setting up swapspace version 1, size = 511996 KiB

  8. no label, UUID=a44009c0-9d5e-4ea5-b9db-f8ae81b16a0b

  9. [root@rac1 selinux]# swapon /root/swapfile1

 

  1. [root@rac1 selinux]# free -m

  2. total used free shared buffers cached

  3. Mem: 1500 1428 71 0 20 1238

  4. -/+ buffers/cache: 169 1331

  5. 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

 

  1. [root@pos.d]# service iptables stop

  2. iptables：清除防火墙规则：[确定]

  3. iptables：将链设置为政策 ACCEPT：filter [确定]

  4. iptables：正在卸载模块：[确定]

  5. [root@pos.d]# chkconfig iptables off


16、关闭selinux

 

  1. [root@pos.d]# getenforce

  2. Enforcing

  3. [root@pos.d]# setenforce 0

  4. [root@pos.d]# getenforce

  5. Permissive

vi /etc/selinux/config

修改SELINUX的值为permissive

SELINUX=permissive

17、关闭ipv6

 

  1. [root@rac1 selinux]# service ip6tables stop

  2. ip6tables：清除防火墙规则：[确定]

  3. ip6tables：将 chains 设置为 ACCEPT 策略：filter [确定]

  4. ：正在卸载模块：[确定]

  5. [root@rac1 selinux]# chkconfig ip6tables off

  6. [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：

Packages for Oracle Linux 6 and Red Hat Enterprise Linux 6

The following packages (or later versions) must be installed:

binutils-2.20.51.0.2-5.11.el6 (x86_64)

安装依赖包：

 

20、修改环境变量

为grid用户设置环境变量
Su - grid
Echo $SHELL
Vi /home/grid/.bash_profile

新增下列内容：

export ORACLE_SID=+ASM1
export ORACLE_BASE=/taryartar/12c/grid_base

export ORACLE_HOSTNAME=rac1.taryartar
export DB_UNIQUE_NAME=tar
export CVUQDISK_GRP=oinstall
umask 022

使环境变量立即生效：

source .bash_profile

 

 

21、修改oracle环境变量

Su - oracle
Echo $SHELL
Vi /home/oracle/.bash_profile

新增下列内容：

export ORACLE_BASE=/taryartar/12c/db_base
export ORACLE_HOME=$ORACLE_BASE/db_home
export ORACLE_SID=tar1
export ORACLE_OWNER=oracle
export ORACLE_TERM=vt100

  27. export LD_LIBRARY_PATH

  28. CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

  29. CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlib

  30. export CLASSPATH

  31. export ORACLE_HOSTNAME=rac1.taryartar

  32. export DB_UNIQUE_NAME=tar

  33. export CVUQDISK=oinstall

  34. umask 022

使环境变量立即生效：

source .bash_profile

 

22、修改内核参数

Su - root
Vi /f
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
_default = 262144
_max = 4194304
wmem_default = 262144
wmem_max = 1048586

[root@rac1 ssh]# vi /f
 

  1. # Controls the maximum shared segment size, in bytes

  2. #kernel.shmmax = 68719476736

  3.  

  4. # Controls the maximum number of shared memory segments, in pages

  5. #kernel.shmall = 4294967296

  6.  

  7. ##add by wufan 2017/10/15

  8.  

  9. fs.aio-max-nr = 1048576

  10. fs.file-max = 6815744

  11. kernel.shmall = 2097152

  12. #物理内存的50-60%

  13. kernel.shmmax = 1046898278

  14. kernel.shmmni = 4096

  15. kernel.sem = 250 32000 100 128

  16. net.ipv4.ip_local_port_range = 9000 65500

使内核参数立即生效

 

  1. [root@rac1 ssh]# sysctl -p

  2. net.ipv4.ip_forward = 0

  3. f.default.rp_filter = 1

  4. f.default.accept_source_route = 0

  5. kernel.sysrq = 0

  6. <_uses_pid = 1

  7. p_syncookies = 1

  8. error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key

  9. error: "net.bridge.bridge-nf-call-iptables" is an unknown key

  10. error: "net.bridge.bridge-nf-call-arptables" is an unknown key

  11. kernel.msgmnb = 65536

  12. kernel.msgmax = 65536

  13. fs.aio-max-nr = 1048576

  14. fs.file-max = 6815744

  15. kernel.shmall = 2097152

  16. kernel.shmmax = 1046898278

  17. kernel.shmmni = 4096

  18. kernel.sem = 250 32000 100 128

  19. net.ipv4.ip_local_port_range = 9000 65500

查看内核是否生效

 

  1. [root@rac1 ssh]# sysctl -a |grep shmmax

  2. kernel.shmmax = 1046898278


23、修改用户资源限制

[root@rac1 ssh]# vi /etc/f

新增如下内容：

 

  1. oracle soft nproc 2047

  2. oracle hard nproc 16384

  3. oracle soft nofile 1024

  4. oracle hard nofile 65536

  5. grid soft nproc 16384

  6. grid hard nproc 16384

  7. grid soft nofile 65536

  8. grid hard nofile 65536

  9. grid soft stack 10240

  10. 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：

 

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

 

  1. [oracle@rac2 ~]$ vi /etc/sysconfig/network

  2.  

  3. NETWORKING=yes

  4. HOSTNAME=rac2

[root@rac2 ~]# hostname rac2
 

  1. [root@rac2 ~]# hostname

  2. rac2

hostname改成rac2

 

  1. [root@rac2 ~]# vi /etc/sysconfig/network-scripts/ifcfg-bond0

  2.  

  3. DEVICE=bond0

  4. IPADDR=192.168.0.52

  5. NETMASK=255.255.255.0

  6. USERCTL=no

  7. BOOTPROTO=none

  8. ONBOOT=yes

  9. GATEWAY=192.168.0.1

  10. IPV6INIT=no

  11. TYPE=Ethernet

  12. #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

 

  1. [root@rac2 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth2

  2.  

  3. DEVICE=eth2

  4. HWADDR=08:00:27:18:29:48

  5. TYPE=Ethernet

  6. ONBOOT=yes

  7. NM_CONTROLLED=yes

  8. BOOTPROTO=none

  9. IPV6INIT=no

  10. USERCTL=no

  11. IPADDR=10.0.10.3

  12. NETMASK=255.255.255.0

  13. 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

 

  1. [root@rac2 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth3

  2.  

  3. DEVICE=eth3

  4. HWADDR=08:00:27:59:1e:79

  5. TYPE=Ethernet

  6. ONBOOT=yes

  7. BOOTPROTO=none

  8. IPADDR=10.0.10.4

  9. NETMASK=255.255.255.0

  10. GATEWAY=192.168.0.1

  11. IPV6INIT=no

  12. 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。

 

  1. [root@rac2 ~]# nslookup rac3

  2. Server: 192.168.0.88

  3. Address: 192.168.0.88#53

  4.  

  5. Name: rac3.taryartar

  6. Address: 192.168.0.53

  7.  

  8. [root@rac2 ~]# nslookup rac2.taryartar

  9. Server: 192.168.0.88

  10. Address: 192.168.0.88#53

  11.  

  12. Name: rac2.taryartar

  13. Address: 192.168.0.52

  14.  

  15. [root@rac2 ~]# nslookup 192.168.0.54

  16. Server: 192.168.0.88

  17. Address: 192.168.0.88#53

  18.  

  19. 54.0.168.192.in-addr.arpa name = rac4.taryartar.

  20.  

  21. [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

 

  1. [root@rac2 ~]# su - grid

  2. [grid@rac2 ~]$ vi .bash_profile

  3.  

  4. # User specific environment and startup programs

  5.  

  6. PATH=$PATH:$HOME/bin

  7.  

  8. export PATH

  9.  

  10. #add by wufan 2017/1015

  11. export ORACLE_SID=+ASM2

  12. export ORACLE_BASE=/taryartar/12c/grid_base

  13. export ORACLE_HOME=/taryartar/12c/grid_home

  14. export GRID_HOME=$ORACLE_HOME

  15. export ORACLE_TERM=xterm

  16. export TMP=/tmp

  17. export TMPDIR=$TMP

  18. #PATH=$PATH:$HOME/bin

  19. export PATH=/usr/sbin:$PATH:$ORACLE_HOME/bin

  20. export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

  21. export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

  22. export ORACLE_HOSTNAME=rac2.taryartar

  23. export DB_UNIQUE_NAME=tar

  24. export CVUQDISK_GRP=oinstall

  25. 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：

 

  1. [grid@rac2 ~]$ env |grep -i oracle_sid

  2. ORACLE_SID=+ASM2

  3. [grid@rac2 ~]$ env|grep -i oracle_hostname

  4. ORACLE_HOSTNAME=rac2.taryartar

  5. [grid@rac2 ~]$


30、修改oracle用户环境变量

 

  1. [root@rac2 ~]# su - oracle

  2. [oracle@rac2 ~]$ vi .bash_profile

  3.  
  4.  

  5. PATH=$PATH:$HOME/bin

  6.  

  7. export PATH

  8.  

  9. #add by wufan 2017/10/15

  10. export ORACLE_BASE=/taryartar/12c/db_base

  11. export ORACLE_HOME=$ORACLE_BASE/db_home

  12. export ORACLE_SID=tar2

  13. export ORACLE_OWNER=oracle

  14. export ORACLE_TERM=vt100

  15. export PATH=$PATH:$ORACLE_HOME/bin

  16. export PATH=$ORACLE_HOME/Apache/Apache/bin:$PATH

  17. export BASE_PATH=/usr/sbin:$PATH:$BASE_PATH

  18. export PATH=$BASE_PATH

  19. LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/usr/local/lib

  20. export LD_LIBRARY_PATH

  21. CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

  22. CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlib

  23. export CLASSPATH

  24. export ORACLE_HOSTNAME=rac2.taryartar

  25. export DB_UNIQUE_NAME=tar

  26. 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：

 

 

  1. [oracle@rac2 ~]$ env|grep -i oracle_sid

  2. ORACLE_SID=tar2

  3. [oracle@rac2 ~]$ env|grep -i oracle_hostname

  4. ORACLE_HOSTNAME=rac2.taryartar

  5. [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 FilesOracleVirtualBoxVBoxManage createhd --filename E:实验环境12CRACV_SHAREStaryartar1.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。

 

  1. VBoxManage createhd --filename E:实验环境12CRACV_SHAREStaryartar1.vdi --size 12288 --format VDI --variant Fixed

  2. VBoxManage createhd --filename E:实验环境12CRACV_SHAREStaryartar2.vdi --size 12288 --format VDI --variant Fixed

  3. VBoxManage createhd --filename E:实验环境12CRACV_SHAREStaryartar3.vdi --size 2048 --format VDI --variant Fixed

  4. VBoxManage createhd --filename E:实验环境12CRACV_SHAREStaryartar4.vdi --size 2048 --format VDI --variant Fixed

  5. VBoxManage createhd --filename E:实验环境12CRACV_SHAREStaryartar5.vdi --size 2048 --format VDI --variant Fixed

  6. VBoxManage createhd --filename E:实验环境12CRACV_SHAREStaryartar6.vdi --size 2048 --format VDI --variant Fixed

  7. VBoxManage createhd --filename E:实验环境12CRACV_SHAREStaryartar7.vdi --size 2048 --format VDI --variant Fixed

命令说明:

VBoxManage 是virtualbox安装目录中的命令&#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12CRACV_SHAREStaryartar1.vdi --mtype shareable

图中虚拟机名称：

端口号指的是：

 

  1. VBoxManage storageattach rac1-12c --storagectl "SATA" --port 4 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar1.vdi --mtype shareable

  2. VBoxManage storageattach rac1-12c --storagectl "SATA" --port 5 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar2.vdi --mtype shareable

  3. VBoxManage storageattach rac1-12c --storagectl "SATA" --port 6 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar3.vdi --mtype shareable

  4. VBoxManage storageattach rac1-12c --storagectl "SATA" --port 7 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar4.vdi --mtype shareable

  5. VBoxManage storageattach rac1-12c --storagectl "SATA" --port 8 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar5.vdi --mtype shareable

  6. VBoxManage storageattach rac1-12c --storagectl "SATA" --port 9 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar6.vdi --mtype shareable

  7. VBoxManage storageattach rac1-12c --storagectl "SATA" --port 10 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar7.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。

 

  1. VBoxManage modifyhd E:实验环境12CRACV_SHAREStaryartar1.vdi --type shareable

  2. VBoxManage modifyhd E:实验环境12CRACV_SHAREStaryartar2.vdi --type shareable

  3. VBoxManage modifyhd E:实验环境12CRACV_SHAREStaryartar3.vdi --type shareable

  4. VBoxManage modifyhd E:实验环境12CRACV_SHAREStaryartar4.vdi --type shareable

  5. VBoxManage modifyhd E:实验环境12CRACV_SHAREStaryartar5.vdi --type shareable

  6. VBoxManage modifyhd E:实验环境12CRACV_SHAREStaryartar6.vdi --type shareable

  7. VBoxManage modifyhd E:实验环境12CRACV_SHAREStaryartar7.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：

 

  1. VBoxManage storageattach rac2-12c --storagectl "SATA" --port 4 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar1.vdi --mtype shareable

  2. VBoxManage storageattach rac2-12c --storagectl "SATA" --port 5 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar2.vdi --mtype shareable

  3. VBoxManage storageattach rac2-12c --storagectl "SATA" --port 6 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar3.vdi --mtype shareable

  4. VBoxManage storageattach rac2-12c --storagectl "SATA" --port 7 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar4.vdi --mtype shareable

  5. VBoxManage storageattach rac2-12c --storagectl "SATA" --port 8 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar5.vdi --mtype shareable

  6. VBoxManage storageattach rac2-12c --storagectl "SATA" --port 9 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar6.vdi --mtype shareable

  7. VBoxManage storageattach rac2-12c --storagectl "SATA" --port 10 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar7.vdi --mtype shareable

  8.  
  9.  

  10. VBoxManage storageattach rac3-12c --storagectl "SATA" --port 4 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar1.vdi --mtype shareable

  11. VBoxManage storageattach rac3-12c --storagectl "SATA" --port 5 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar2.vdi --mtype shareable

  12. VBoxManage storageattach rac3-12c --storagectl "SATA" --port 6 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar3.vdi --mtype shareable

  13. VBoxManage storageattach rac3-12c --storagectl "SATA" --port 7 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar4.vdi --mtype shareable

  14. VBoxManage storageattach rac3-12c --storagectl "SATA" --port 8 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar5.vdi --mtype shareable

  15. VBoxManage storageattach rac3-12c --storagectl "SATA" --port 9 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar6.vdi --mtype shareable

  16. VBoxManage storageattach rac3-12c --storagectl "SATA" --port 10 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar7.vdi --mtype shareable

  17.  
  18.  

  19. VBoxManage storageattach rac4-12c --storagectl "SATA" --port 4 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar1.vdi --mtype shareable

  20. VBoxManage storageattach rac4-12c --storagectl "SATA" --port 5 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar2.vdi --mtype shareable

  21. VBoxManage storageattach rac4-12c --storagectl "SATA" --port 6 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar3.vdi --mtype shareable

  22. VBoxManage storageattach rac4-12c --storagectl "SATA" --port 7 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar4.vdi --mtype shareable

  23. VBoxManage storageattach rac4-12c --storagectl "SATA" --port 8 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar5.vdi --mtype shareable

  24. VBoxManage storageattach rac4-12c --storagectl "SATA" --port 9 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar6.vdi --mtype shareable

  25. VBoxManage storageattach rac4-12c --storagectl "SATA" --port 10 --device 0 --type hdd --medium E:实验环境12CRACV_SHAREStaryartar7.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。

 

 

  1. [root@rac1 ~]# fdisk -l|grep Di

  2. Disk /dev/sda: 32.2 GB, 32212254720 bytes

  3. Disk identifier: 0x000ca0fb

  4. Disk /dev/sdb: 12.9 GB, 12884901888 bytes

  5. Disk identifier: 0x00000000

  6. Disk /dev/sdc: 12.9 GB, 12884901888 bytes

  7. Disk identifier: 0x00000000

  8. Disk /dev/sdd: 2147 MB, 2147483648 bytes

  9. Disk identifier: 0x00000000

  10. Disk /dev/sde: 2147 MB, 2147483648 bytes

  11. Disk identifier: 0x00000000

  12. Disk /dev/sdf: 2147 MB, 2147483648 bytes

  13. Disk identifier: 0x00000000

  14. Disk /dev/sdg: 2147 MB, 2147483648 bytes

  15. Disk identifier: 0x00000000

  16. Disk /dev/sdh: 2147 MB, 2147483648 bytes

  17. Disk identifier: 0x00000000

  18. Disk /dev/mapper/vg_rac1-lv_root: 28.5 GB, 28529655808 bytes

  19. Disk identifier: 0x00000000

  20. Disk /dev/mapper/vg_rac1-lv_swap: 3154 MB, 3154116608 bytes

  21. 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：

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

  11. [root@rac2 ~]# 

 

  1. [root@rac3 ~]# fdisk -l|grep Linux

  9. /dev/sdg1 1 261 2096451 83 Linux

  10. /dev/sdh1 1 261 2096451 83 Linux

  11. [root@rac3 ~]# 

 

  1. [root@rac4 ~]# fdisk -l|grep Linux

  2. /dev/sda1 * 1 64 512000 83 Linux

  3. /dev/sda2 64 3917 30944256 8e Linux LVM

  9. /dev/sdg1 1 261 2096451 83 Linux

  10. /dev/sdh1 1 261 2096451 83 Linux

  11. [root@rac4 ~]#

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"

 

  1. [root@rac1 rules.d]# vi 99-ASM.rules

  2.  

  3. ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"

  4. ACTION=="add", KERNEL=="sdc1", RUN+="/bin/raw /dev/raw/raw2 %N"

  5. ACTION=="add", KERNEL=="sdd1", RUN+="/bin/raw /dev/raw/raw3 %N"

  6. ACTION=="add", KERNEL=="sde1", RUN+="/bin/raw /dev/raw/raw4 %N"

  7. ACTION=="add", KERNEL=="sdf1", RUN+="/bin/raw /dev/raw/raw5 %N"

  8. ACTION=="add", KERNEL=="sdg1", RUN+="/bin/raw /dev/raw/raw6 %N"

  9. ACTION=="add", KERNEL=="sdh1", RUN+="/bin/raw /dev/raw/raw7 %N"

  10. 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：

 

  1. [root@rac1 rules.d]# start_udev

  2. 正在启动 udev：[确定]

  3. [root@rac1 rules.d]# 

 

  1. [root@rac2 rules.d]# start_udev

  2. 正在启动 udev：[确定]

  3. [root@rac2 rules.d]# 

 

  1. [root@rac3 rules.d]# start_udev

  2. 正在启动 udev：[确定]

  3. [root@rac3 rules.d]# 

 

  1. [root@rac4 rules.d]# start_udev

  2. 正在启动 udev：[确定]

  3. [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：

 

  1. Oct 15 21:46:36 rac2 kdump: No crashkernel parameter specified for running kernel

  2. Oct 15 21:46:36 rac2 acpid: starting up

  3. Oct 15 21:46:36 rac2 acpid: 1 rule loaded

  4. Oct 15 21:46:36 rac2 acpid: waiting for events: event logging is off

  5. Oct 15 21:46:37 rac2 acpid: client connected from 1669[68:68]

  6. Oct 15 21:46:37 rac2 acpid: 1 client rule loaded

  7. Oct 15 21:46:39 rac2 automount[1690]: lookup_read_master: lookup(nisplus): couldn't locate nis+ table auto.master

  8. Oct 15 21:46:39 rac2 mcelog: mcelog read: No such device

  9. Oct 15 21:46:39 rac2 abrtd: Init complete, entering main loop

  10. Oct 15 22:37:15 rac2 kernel: udev: starting version 147

  11. Oct 15 22:37:16 rac2 udevd-work[2074]: error changing netif name 'eth1' to 'eth0': Device or resource busy




此情况只需要重启另外三个节点即可。

重启后的节点2-4如下：

ok，裸设备配置完成。
