****************************************************************************
*CentOS4.4+RHCS（DLM）+GFS+Oracle10gR2RAC+VMWareServer1.0.1安装*
****************************************************************************
一、测试环境
主机：
一台PC,AMD-64位的芯片，4G内存,安装CentOS-4.4-x86_64版本的操作系统
在这个主机上面安装了2个虚拟机，全部安装CentOS-4.4-x86_64版本的操作系统，未进行内核定制，网上更新到最新
二、安装VMWareServer1.0.1forlinux
三、创建共享磁盘
vmware-vdiskmanager-c-s6Gb-alsilogic-t2"/vmware/share/ohome.vmdk" |用于SharedOracleHome
vmware-vdiskmanager-c-s10Gb-alsilogic-t2"/vmware/share/odata.vmdk" |用于datafilesandindexes
vmware-vdiskmanager-c-s3Gb-alsilogic-t2"/vmware/share/oundo1.vmdk" |用于node1RedologsandUndotablespaces
vmware-vdiskmanager-c-s3Gb-alsilogic-t2"/vmware/share/oundo2.vmdk" |用于node2RedologsandUndotablespaces
vmware-vdiskmanager-c-s512Mb-alsilogic-t2"/vmware/share/oraw.vmdk" |用于Oracle集群注册表文件和CRS表决磁盘
2个虚拟机使用一个共享磁盘
四、安装虚拟机
1.在vmwareconsole创建vmwareguestOS,取名gfs-node01,选择customecreate->RedhatEnterpriseLinux464-bit，其它都是默认.
内存选择1G（>800MB你就看不到warning了）,硬盘大小选择12GB,建立方式不选择pre-allocated
2.创建好后vmwareguestOS之后,给guest加上一块NIC（也就是网卡）
3.关掉vmwareconsole，在node1目录下面，打开gfs-node1.vmx,在最后空白处添加以下内容
scsi1.present="TRUE"
scsi1.virtualDev="lsilogic"
scsi1.sharedBus="virtual"
scsi1:
1.present="TRUE"
scsi1:
1.mode="independent-persistent"
scsi1:
1.filename="/vmware/share/ohome.vmdk"
scsi1:
1.deviceType="disk"
scsi1:
2.present="TRUE"
scsi1:
2.mode="independent-persistent"
scsi1:
2.filename="/vmware/share/odata.vmdk"
scsi1:
2.deviceType="disk"
scsi1:
3.present="TRUE"
scsi1:
3.mode="independent-persistent"
scsi1:
3.filename="/vmware/share/oundo1.vmdk"
scsi1:
3.deviceType="disk"
scsi1:
4.present="TRUE"
scsi1:
4.mode="independent-persistent"
scsi1:
4.filename="/vmware/share/oundo2.vmdk"
scsi1:
4.deviceType="disk"
scsi1:
5.present="TRUE"
scsi1:
5.mode="independent-persistent"
scsi1:
5.filename="/vmware/share/oundo3.vmdk"
scsi1:
5.deviceType="disk"
scsi1:
6.present="TRUE"
scsi1:
6.mode="independent-persistent"
scsi1:
6.filename="/vmware/share/oraw.vmdk"
scsi1:
6.deviceType="disk"
disk.locking="false"
diskLib.dataCacheMaxSize="0"
diskLib.dataCacheMaxReadAheadSize="0"
diskLib.DataCacheMinReadAheadSize="0"
diskLib.dataCachePageSize="4096"
diskLib.maxUnsyncedWrites="0"
这段是对vmware使用共享硬盘的方式进行定义，大多数人都知道设置disk.locking="false"却漏掉dataCache
保存退出之后，重新打开你的vmware-console,你就可以看到vmwareguestOS的配置中，都有这些硬盘出现了.
五、需要安装的包以及顺序
可以用yum安装:
1、升级CentOS4.4
yumupdate
2、安装csgfs
yuminstallyumex
cd/etc/yum.repos.d
wgethttp:
//mirror.centos.org/centos/4/csgfs/CentOS-csgfs.repo
yumex
也可以手动rpm安装:
包下载地址：
http:
//mirror.centos.org/centos/4/csgfs/x86_64/RPMS/
1、在所有节点上安装必须的软件包，软件包完整列表请参考GFS6.1用户手册

2、安装软件和顺序
安装脚本，install.sh

rpm-ivhmagma-plugins-1.0.9-0.x86_64.rpm
rpm-ivhrgmanager-1.9.53-0.x86_64.rpm
rpm-ivhsystem-config-cluster-1.0.25-1.0.noarch.rpm
rpm-ivhipvsadm-1.24-6.x86_64.rpm
rpmivhpiranha-0.8.2-1.x86_64.rpm--nodeps
注意：
有些包有依赖关系，使用nodeps开关进行安装即可
3、修改各个节点上的/etc/hosts文件（每个节点都一样）
如下：
[root@gfs-node1etc]#cathosts
#Donotremovethefollowingline,orvariousprograms
#thatrequirenetworkfunctionalitywillfail.
127.0.0.1 localhost.localdomainlocalhost
192.168.154.211gfs-node1
192.168.154.212gfs-node2
192.168.10.1 node1-prv
192.168.10.2 node2-prv
192.168.154.201node1-vip
192.168.154.202node2-vip
注意：
主机名、cluster主机名、ocs中的pub节点名最好相同。
六、运行system-config-cluster进行配置
增加2个节点，节点的权置全部设置为1，即Quorum值设置为1
三个节点的名称为:
gfs-node1
gfs-node2
修改cluster.conf文件，如下：
[root@gfs-node1~]#cat/etc/cluster/cluster.conf
xmlversion="1.0"?
>
[注意]Usefence_bladecenter. Thiswillrequirethatyouhavetelnetenabledon
yourmanagementmodule（mayrequireafirmwareupdate）
使用scp命令把这个配置文件copy到node2节点上
七、在01/02节点上启动dlm,ccsd,fence等服务
可能在安装配置完上述步骤后，下面这些服务已经起来了。
在2个节点上加载dlm模块
[root@gfs-node1cluster]#modprobelock_dlm
[root@gfs-node2cluster]#modprobelock_dlm
5.2、启动ccsd服务
[root@gfs-node1cluster]#ccsd
[root@gfs-node2cluster]#ccsd
5.3、启动集群管理器（cman）
root@gfs-node1#/sbin/cman_tooljoin
root@gfs-node2#/sbin/cman_tooljoin
5.4、测试ccsd服务
（注意：
ccsd的测试要等cman启动完成后，然后才可以进行下面的测试
[root@gfs-node1cluster]#ccs_testconnect
[root@gfs-node2cluster]#ccs_testconnect
#ccs_testconnect各个节点的返回如下：
node1：
[root@gfs-node1cluster]#ccs_testconnect
Connectsuccessful.
Connectiondescriptor=0
node2：
[root@gfs-node2cluster]#ccs_testconnect
Connectsuccessful.
Connectiondescriptor=30
5.5、查看节点状态
cat/proc/cluster/nodes,应该返回
[root@gfs-node1cluster]#cat/proc/cluster/nodes
Node VotesExpSts Name
1 1 3 M gfs-node1
2 1 3 M gfs-node2
