1. 到redhat 网站上下载相应的Cluster Suite/GFS软件。因为没有注册号，没法经过up2date升级，所以会比较麻烦。
到ftp: //ftp.redhat.com/pub/redhat/linux/updates/enterprise/4AS/en/下载相应的RHCS和 RHGFS的src.rpm文件，在一个目录下，每每有相同软件的几个版本存在。如下安装笔记中所使用的软件是以RHAS4 U2为准。

安装完毕
2. 完成GFS server的配置（该文章参考suran007 的GFS6.1 ON RHAS4 U2安装文档）
2.1 确保相关设备的主机名和IP地址的对应关系都在/etc/hosts中
例：
10.1.5.161 host1
10.1.5.162 host2
10.1.5.163 host3 #host3做为gnbd的server
2.2 在host3上配置GFS经过gnbd进行export
启动gnbd_serv进程
root@host3 # /sbin/gnbd_serv –v –n
导出设备
root@host3# gnbd_export -v -e gfs -d /dev/sdb1 –c
查看export状态信息
root@host3# gnbd_export -v -l
完成GFS server，为了使实验更顺利，建议将防火墙停掉 service iptables stop
3. 使用system-config-cluster工具对node1和node2进行配置
在node1的命令格式下输入：system-config-cluster,进入配置界面
3.1而后在系统中，第一次配置会提示是否要建立配置文件/etc/cluster/cluster.conf，点击"create "
3.2而后选择 锁机制，选择dlm。
3.3添加cluster nodes。
点击“add a cluster node",添加node1,quorum votes填1。
点击“add a cluster node",添加node2,quorum votes填1。
3.4 添加fence设备
在”fence device"中，选择“add a fence device"，这里添加的是"manual Fencing"，名字任意，这里写”web"。
在"cluster Nodes->node1和node2”,中“manange fencing for this node"，选择”add a fence level"。
3.5 建立"failover domains"
在“manager resource->failover domains"中，”create a failover domain"，名称为web
点击“manager resource->failover domains->web","edit failover domain propertis"，在"available cluster node2"中，将node1和node2都添加进取。
3.6 建立”resource"
"create a resource"，选择IP address,地址为“10.1.5.169",后边的monitor link要选中。
"create a resource"，选择script，name 为"httpd",script为"/etc/init.d/httpd"。
先保存，而后将cluster.conf传到node2相同位置一份。下边要配置gfs的一些resource，可是前提是cluster mananger的进程须要启动才能进行设置。
4. 配置GFS参数
启动cluster进程顺序：
service ccsd start
service cman start
service fenced start
service clvmd start
service gfs start
service rgmanager start
而后在node1上，首先
modprobe gnbd
将gfs经过gnbd倒入：gnbd_import -v -i node3
检查加载状态：gnbd_import -v -l
modeprobe gfs
gfs_mkfs -p lock_dlm -t cluster1:gfs -j 2 /dev/gnbd/gfs 建立文件系统
在node2上重复此操做，只是不用再重作建立文件系统的操做
再打开system-config-cluster，
接着建立"resource"
"create a resource"，选择GFS,name "web_content",mount point:"/gfs",device:"dev/gnbd/gfs"。
5.配置service
因为是为了实现httpd的集群，所以须要对/etc/httpd/conf/httpd.conf一些内容进行修改，包括
设置监听地址为floating ip：Listen 10.1.5.169:80
修改DocumentRoot 为"/gfs/"
<Directory "/gfs/">
同时chkconfig httpd off,将httpd 的自启动关闭
"service","create a service", name设为httpd。
failover domain为 web。
点”add a shared resource to this service" ,首先把ip address加入。
选择”10.1.5.169 ip address share",而后再“attach a shared resource to the selecetion",分别添加刚才设的script和gfs的resource。
保存配置,并复制该文件到node2。
分别从新启动进程：
service rgmanager stop
service gfs stop
service clvmd stop
service fenced stop
service cman stop
service ccsd stop
service ccsd start
service cman start
service fenced start
service clvmd start
service gfs start
service rgmanager start
6. 开启service
打开，system-config-cluster，若是刚才的管理进程都正常的话，将会有cluster management的tab。
在service 中，点击httpd 按"enable"启动。
debug技巧：若是没法正常启动，尝试着去掉一些resource，而后再看是否正常启动，来定位故障。
