Veritas Cluster Server 4.0安装指南

UU的实验室里面有一组放在那里不用的双机+盘阵,于是尝试从头开始安装一套cluster。

硬件简述:
1. Node1: Netra 20 (2 X UltraSPARC-III+, 2048M RAM, 72G*2 HardDisk)
2. Node2: Netra 20 (2 X UltraSPARC-III+, 2048M RAM, 72G*2 HardDisk)
3. Shared Storage: D1000 (36G*3 HardDisk)

一. 安装操作系统
安装2/04版本(2004年2月份)的Solaris 8。在安装过程中需要选择英文作为主要语言。

二. 安装EIS-CD
安装EIS-CD 2/04版本,EIS-CD用于设置使用cluster的环境变量。

三. 安装patch
为了避免CPU虚高的问题,需要安装117000-05补丁。该补丁可以从SUN公司官方网站下载。下载该补丁以后解压将生成117000-05目录。使用如下命令安装patch:
patchadd 117000-05

四. 安装共享磁盘
在本次环境中,我们使用SUN D1000盘阵作为共享磁盘,是SCSI接口的盘阵,如果是光纤接口的盘阵需要另行设置。
1. 给盘阵加电
2. 将Node1和盘阵用SCSI连线连接
3. Node1加电
4. 使Node1进入ok模式(在console窗口监控Node1的启动,当出现启动信息时,迅速按下Ctrl+Break,即可进入ok模式)
5. {0} ok probe-scsi-all
6. {0} ok boot –r
7. 重新启动以后进入操作系统,使用format命令确认盘阵已经被此系统加载
8. Node1断电,Node2加电,重复4-7步,确认盘阵也可以被此台机器加载
9. 为了使两台机器同时读取共享存储,需要修改其中一台机器的SCSI ID。给Node1加电,进入ok模式(此时的状态应该是Node1,Node2,存储均已加电,Node2目前使用format命令已经可以观察到盘阵被正常加载,Node1处于ok模式)。
10. 设置Node1的SCSI ID为5(默认为7)
{0} ok setenv scsi-initiator-id 5
11. 通过第5步中的屏幕信息我们可以知道该SCSI设备的系统表示符为/pci@8,700000/scsi@2,1,这个标识符将在下一步使用
12. 设置Node1的SCSI ID为5。(注意第2行的输入中" scsi-initiator-id",双引号之后有一个空格!)
{0} ok nvedit
0: probe-all
1: cd /pci@8,700000/scsi@2,1
2: 5 " scsi-initiator-id" integer-property
3: device-end
4: install-console
5: banner
13. 保存第12步的配置
{0} ok nvstore
14. 设置环境变量
{0} ok setenv use-nvramrc? true
use-nvramrc? = true
{0} ok setenv auto-boot? true
auto-boot? = true
15. 重新启动Node1
{0} ok reset-all
16. 在Node1,Node2上均用format命令检查,确认都成功挂载了共享存储

五. 安装VCS
1. 设置rhosts文件,在两台机器上都要执行,以下以Node1为例。
在/目录下添加rhosts文件,使远程登陆生效,用以简便地在两台机器上同时安装VCS
root@uulab-s22 # echo “+” > /.rhosts
root@uulab-s22 # more /.rhosts
+

2. 设置多个网卡IP
由于Cluster系统中的心跳网卡最好是一个独立的网络设备,所以我们在两台机器上设置另外一个网卡和IP地址,专门用于心跳设备。在两台机器上都要执行,以下以Node1为例。
root@uulab-s22 # echo "uulab-p22" > /etc/hostname.qfe0
root@uulab-s22 # touch /etc/notrouter
root@uulab-s22 # vi /etc/hosts
添加如下行:
192.168.0.6 uulab-p22
192.168.0.8 uulab-p23
root@uulab-s22 # vi /etc/netmasks
添加如下行:
192.168.0.0 255.255.255.0
root@uulab-s22 # sync
root@uulab-s22 # reboot

3. 开始安装
VCS 4.0的安装已经可以简化到只使用一个命令,将同时安装Veritas Volume Manager 4.0, Veritas File System 4.0,Veritas Cluster Server 4.0以及其他一些相关软件。以下命令只需要在一个节点中执行即可。
root@uulab-s22 # cd /opt/sf_ha.4.0.sol/storage_foundation
root@uulab-s22 # ./installsf
安装过程一路都是选择或者按照提示输入,总的来说比较简单,不再赘述。

六. 创建磁盘组
VCS安装完毕以后,将要求使用如下命令重新启动所有节点:
shutdown -y -i6 -g0

重启完毕,开始创建磁盘组。以下命令只需要在一个节点中执行即可。
使用format命令确认我们需要添加到磁盘组中的共享磁盘为c4t0d0,c4t8d0,c4t9d0
root@uulab-s22 # format
Searching for disks...done


AVAILABLE DISK SELECTIONS:
0. c1t0d0
/pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w2100000c50569190,0
1. c1t1d0
/pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w2100000c5056c1a7,0
2. c4t0d0
/pci@8,700000/scsi@2,1/sd@0,0
3. c4t8d0
/pci@8,700000/scsi@2,1/sd@8,0
4. c4t9d0
/pci@8,700000/scsi@2,1/sd@9,0
Specify disk (enter its number):

root@uulab-s22 # vxdisksetup -i c4t0d0
如果此命令执行以后报错如下,那么参看附录中的解决方法1。
VxVM vxdisksetup ERROR V-5-2-3535 c4t0d0s2: Invalid dmpnodename for disk device c4t0d0.
如果此命令执行以后报错如下,那么参看附录中的解决方法2。
VxVM vxdisksetup ERROR V-5-2-1813 c4t0d0: Disk is part of ipasdg disk group, use -f option to force setup.

root@uulab-s22 # vxdisksetup -i c4t8d0
root@uulab-s22 # vxdisksetup -i c4t9d0

root@uulab-s22 # vxdg init hlrdg hlrdg-01=c4t0d0
root@uulab-s22 # vxdg -g hlrdg adddisk hlrdg-02=c4t8d0
root@uulab-s22 # vxdg -g hlrdg adddisk hlrdg-03=c4t9d0

七. 创建卷
root@uulab-s22 # vxassist -g hlrdg -b make oradata_vol 15g layout=nostripe,nolog nmirror=2 &
root@uulab-s22 # vxassist -g hlrdg -b make oraredo_vol 5g layout=nostripe,nolog nmirror=2 &
root@uulab-s22 # vxassist -g hlrdg -b make oraarch_vol 8g layout=nostripe,nolog nmirror=2 &
root@uulab-s22 # vxassist -g hlrdg -b make hlr_vol 4g layout=nostripe,nolog nmirror=2 &

八. 使用VxFS创建文件系统
root@uulab-s22 # mkfs -F vxfs -o bsize=8192,largefiles /dev/vx/rdsk/hlrdg/oradata_vol
root@uulab-s22 # mkfs -F vxfs -o bsize=8192,largefiles /dev/vx/rdsk/hlrdg/oraredo_vol
root@uulab-s22 # mkfs -F vxfs -o bsize=8192,largefiles /dev/vx/rdsk/hlrdg/oraarch_vol
root@uulab-s22 # mkfs -F vxfs -o bsize=8192,largefiles /dev/vx/rdsk/hlrdg/hlr_vol

九. 配置VCS
我们的环境是创建了4个文件系统,分别是oradata_vol, oraredo-vol, oraarch_vol, hlr_vol,文件系统可以被使用需要挂载(mount)到相应的目录中。先创建相应的目录,在两台机器上都要执行,以下以Node1为例。(假设系统中dba组和oracle用户都已经创建)
root@uulab-s22 # mkdir -p /opt/oracle/data
root@uulab-s22 # mkdir -p /opt/oracle/redo
root@uulab-s22 # mkdir -p /opt/oracle/arch
root@uulab-s22 # mkdir –p /opt/hlr

root@uulab-s22 # chown oracle:dba /dev/vx/rdsk/hlrdg/oradata_vol
root@uulab-s22 # chown oracle:dba /dev/vx/rdsk/hlrdg/oraredo_vol
root@uulab-s22 # chown oracle:dba /dev/vx/rdsk/hlrdg/oraarch_vol

root@uulab-s22 # chown oracle:dba /opt/oracle/data
root@uulab-s22 # chown oracle:dba /opt/oracle/redo
root@uulab-s22 # chown oracle:dba /opt/oracle/arch

修改/etc/VRTSvcs/conf/config/main.cf文件,这是VCS的配置文件,该文件的修改可以使用命令行(比如hagrp,hares等命令)修改,也可以使用任何文本编辑器(比如vi)直接修改,此处我们选择使用vi进行修改。粗体字部分为需要新添加的行。

修改完毕以后该文件如下:
include "types.cf"

cluster vcs_hlr_cluster (
UserNames = { admin = hijBidIfjEjjHrjDig }
ClusterAddress = "10.7.1.7" --此处为Cluster环境的虚拟IP
Administrators = { admin }
CounterInterval = 5
)

system uulab-s22 (
)

system uulab-s23 (
)

group ClusterService (
SystemList = { uulab-s22 = 0, uulab-s23 = 1 }
UserStrGlobal = "LocalCluster@https://10.7.1.7:8443;LocalCluster@https://10.7.1.7:8443;"
AutoStartList = { uulab-s22, uulab-s23 }
OnlineRetryLimit = 3
OnlineRetryInterval = 120
)

DiskGroup hlrdg (
DiskGroup = hlrdg
MonitorReservation = 1
)

IP webip (
Device = eri0
Address = "10.7.1.7"
NetMask = "255.255.0.0"
)

Mount arch_mnt (
MountPoint = "/opt/oracle/arch"
BlockDevice = "/dev/vx/dsk/hlrdg/oraarch_vol"
FSType = vxfs
FsckOpt = "-y"
)

Mount data_mnt (
MountPoint = "/opt/oracle/data"
BlockDevice = "/dev/vx/dsk/hlrdg/oradata_vol"
FSType = vxfs
FsckOpt = "-y"
)

Mount hlr_mnt (
MountPoint = "/opt/hlr"
BlockDevice = "/dev/vx/dsk/hlrdg/hlr_vol"
FSType = vxfs
FsckOpt = "-y"
)

Mount redo_mnt (
MountPoint = "/opt/oracle/redo"
BlockDevice = "/dev/vx/dsk/hlrdg/oraredo_vol"
FSType = vxfs
FsckOpt = "-y"
)

NIC csgnic (
Device = eri0
)

VRTSWebApp VCSweb (
Critical = 0
AppName = vcs
InstallDir = "/opt/VRTSweb/VERITAS"
TimeForOnline = 5
RestartLimit = 3
)

VCSweb requires webip
arch_mnt requires hlr_mnt
data_mnt requires redo_mnt
hlr_mnt requires hlrdg
redo_mnt requires arch_mnt
webip requires csgnic

修改完毕,使用如下命令进行语法检查:
root@uulab-s22 # hacf -verify /etc/VRTSvcs/conf/config

十. 测试VCS
配置完成以后,同时重新启动两台机器,启动完毕,使用如下命令检查VCS是否运行正常。
root@uulab-s22 # hares -display -group ClusterService
正常情况应该如下显示:
#Resource Attribute System Value
VCSweb Group global ClusterService
VCSweb Type global VRTSWebApp
VCSweb AutoStart global 1
VCSweb Critical global 0
VCSweb Enabled global 1
VCSweb LastOnline global uulab-s22
VCSweb MonitorOnly global 0
VCSweb ResourceOwner global unknown
VCSweb TriggerEvent global 0
VCSweb ArgListValues uulab-s22 vcs /opt/VRTSweb/VERITAS 5
VCSweb ArgListValues uulab-s23 vcs /opt/VRTSweb/VERITAS 5

VCSweb TimeForOnline global 5
VCSweb MonitorTimeStats uulab-s22 Avg 0 TS
VCSweb MonitorTimeStats uulab-s23 Avg 0 TS
#
…………

也可以使用df命令检查是否所有需要挂载的文件系统都已正确挂载在Node1上,而在Node2上则无法看到。

做切换测试:
root@uulab-s22 # hagrp -switch ClusterService -to uulab-s23
正常情况大概是5秒左右,所有的资源包括IP,文件系统加载点都会转移到Node2上。
