RHCS安装及配置
192.168.1.5 安装luci 两块硬盘, 其中/sdb提供共享存储。
集群节点
192.168.1.6 安装ricci node1.mingxiao.info node1
192.168.1.7 安装ricci node2.mingxiao.info node2
192.168.1.8 安装ricci node3.mingxiao.info node3
前提：
1> 192.168.1.5分别与node1,node2,node3互信
2> 时间同步
3> 节点主机名分别为node1.mingxiao.info、node2.mingxiao.info、node3.mingxiao.info
进主机192.168.1.5
vim /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.6 node1.mingxiao.info node1 192.168.1.7 node2.mingxiao.info node2 192.168.1.8 node3.mingxiao.info node3
# for I in {1..3}; do scp /etc/hosts node$I:/etc;done
时间同步
# for I in {1..3}; do ssh node$I ‘ntpdate time.windows.com‘;done
节点间互信。
.....
# yum -y install luci
# for I in {1..3}; do ssh node$I ‘yum -y install ricci‘; done
# for I in {1..3}; do ssh node$I ‘echo xiaoming | passwd --stdin ricci‘; done
# for I in {1..3}; do ssh node$I ‘service ricci start;chkconfig ricci on‘; done
# for I in {1..3}; do ssh node$I ‘yum -y install httpd‘; done
# service luci start
浏览器输入https://192.168.1.5:8084访问web管理界面，输入root用户和root密码
创建集群，Password输入各节点ricci用户密码，
添加资源，这里添加两个一个为VIP，一个为httpd，添好如下图界面
添加故障转移域，如下图：
由于没有fences设备，所以不再添加。
接下来要配置iscsi，提供共享存储:
进192.168.1.5
# yum -y install scsi-target-utils
# for I in {1..3}; do ssh node$I ‘yum -y install iscsi-initiator-utils‘; done
vim /etc/tgt/targets.conf 添加如下内容 <target iqn.2015-05.ingo.mingxiao:ipsan.sdb> <backing-store /dev/sdb> vendor_id Xiaoming lun 1 </backing-store> initiator-address 192.168.1.0/24 incominguser iscsiuser xiaoming </target>
# service tgtd start
# tgtadm --lld iscsi --mode target --op show #可查看到如下信息 Target 1: iqn.2015-05.ingo.mingxiao:ipsan.sdb System information: Driver: iscsi State: ready LUN information: LUN: 0 Type: controller SCSI ID: IET 00010000 SCSI SN: beaf10 Size: 0 MB, Block size: 1 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: null Backing store path: None Backing store flags: LUN: 1 Type: disk SCSI ID: IET 00010001 SCSI SN: beaf11 Size: 21475 MB, Block size: 512 Online: Yes Removable media: No Prevent removal: No Readonly: No Backing store type: rdwr Backing store path: /dev/sdb Backing store flags: Account information: iscsiuser ACL information: 192.168.1.0/24

node1，node2,node3分别安装以下两个rpm包，rpmfind.net可找到
# rpm -ivh lvm2-cluster-2.02.111-2.el6.x86_64.rpm gfs2-utils-3.0.12.1-68.el6.x86_64.rpm warning: lvm2-cluster-2.02.111-2.el6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY Preparing... ########################################### [100%] 1:gfs2-utils ########################################### [ 50%] 2:lvm2-cluster ########################################### [100%]
进node1
# pvcreate /dev/sdb
# vgcreate clustervg /dev/sdb
# lvcreate -L 5G -n clusterlv clustervg
# mkfs.gfs2 -j 2 -p lock_dlm -t mycluster:sdb /dev/clustervg/clusterlv
添加一个服务，名为webservice
将先前VIP资源加入
新建一个GFS2资源，并加入
将先前httpd资源加入
然后启动即可。
查看状态：
