系统版本：RHEL5.4
关闭SELinux，配置yum仓库，并配置各个服务器的环境

[[email protected] ~]# hostname target.a.com
[[email protected] ~]# vim /etc/hosts
[[email protected] ~]# yum install -y luci scsi-target-utils
[[email protected] ~]# service tgtd start
[[email protected] ~]# tgtadm --lld iscsi --op new --mode target --tid=1 --targetname iqn.2011-10.com.a.target:disk
[[email protected] ~]# fdisk /dev/sdb

[[email protected] ~]# partprobe /dev/sdb
[[email protected] ~]# tgtadm --lld iscsi --op new --mode=logicalunit --tid=1 --lun=1 --backing-store /dev/sdb1
[[email protected] ~]# tgtadm --lld iscsi --op bind --mode=target --tid=1 --initiator-address=192.168.2.0/24
//把上边三句写入开机脚本，完成开机自启动
[[email protected] ~]# echo “tgtadm --lld iscsi --op new --mode target --tid=1 --targetname iqn.2011-10.com.a.target:disk” >> /etc/rc.d/rc.local
[[email protected] ~]# echo “tgtadm --lld iscsi --op new --mode=logicalunit --tid=1 --lun=1 --backing-store /dev/sdb1” >> /etc/rc.d/rc.local
[[email protected] ~]#echo“tgtadm --lld iscsi --op bind --mode=target --tid=1 --initiator-address=192.168.2.0/24” >> /etc/rc.d/rc.local
[[email protected] ~]# luci_admin init
[[email protected] ~]# service luci restart
[[email protected] ~]# chkconfig luci on
[[email protected] ~]# tgtadm --lld iscsi --op show --mode target //查看target接入信息
2> initiator1的配置
[[email protected] ~]# vim /etc/sysconfig/network
HOSTNAME=node1.a.com
[[email protected] ~]# hostname node1.a.com
[[email protected] ~]# vim /etc/hosts
[[email protected] ~]# yum install -y iscsi-initiator-utils ricci httpd
[[email protected] ~]# vim /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.2011-10.com.a.node1
[[email protected] ~]# service iscsi start
[[email protected] ~]# chkconfig iscsi on
[[email protected] ~]# iscsiadm --mode discovery --type sendtargets --portal 192.168.2.30
[[email protected] ~]# iscsiadm --mode node --targetname iqn.2011-10.com.a.target:disk --portal 192.168.2.30 --login
[[email protected] ~]# echo“iscsiadm --mode discovery --type sendtargets --portal 192.168.2.30” >> /etc/rc.d/rc.local
[[email protected] ~]# echo “iscsiadm --mode node --targetname
iqn.2011-10.com.a.target:disk --portal 192.168.2.30 --login” >> /etc/rc.d/rc.local
[[email protected] ~]# service ricci start
[[email protected] ~]# chkconfig ricci on
3> initiator2的配置
[[email protected] ~]# vim /etc/sysconfig/network
HOSTNAME=node2.a.com
[[email protected] ~]# hostname node2.a.com
[[email protected] ~]# vim /etc/hosts
[[email protected] ~]# yum install -y iscsi-initiator-utils ricci httpd
[[email protected] ~]# vim /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.2011-10.com.a.node2
[[email protected] ~]# service iscsi start
[[email protected] ~]# chkconfig iscsi on
[[email protected] ~]# iscsiadm --mode discovery --type sendtargets --portal 192.168.2.30
[[email protected] ~]# iscsiadm --mode node --targetname iqn.2011-10.com.a.target:disk --portal 192.168.2.30 --login
[[email protected] ~]# echo“iscsiadm --mode discovery --type sendtargets --portal 192.168.2.30” >> /etc/rc.d/rc.local
[[email protected] ~]# echo “iscsiadm --mode node --targetname
iqn.2011-10.com.a.target:disk --portal 192.168.2.30 --login” >> /etc/rc.d/rc.local
[[email protected] ~]# service ricci start
[[email protected] ~]# chkconfig ricci on
//此时在target server上查看接入的信息
可以看到两个节点都成功接入target server，接下来开始做群集文件系统
1> 登录luci管理页，https://192.168.2.30:8084
2> 进入管理页后，点击“cluster”——>“Create a New Cluster”
在节点上创建群集文件系统GFS
[[email protected] ~]# mkdir /mnt/1
[[email protected] ~]# fdisk /dev/sdb
[[email protected] ~]# partprobe /dev/sdb //在两个initiator上都做该步骤
[[email protected] ~]# pvcreate /dev/sdb1
[[email protected] ~]# vgcreate vg01 /dev/sdb1
[[email protected] ~]# vgdisplay
[[email protected] ~]# service clvmd restart
[[email protected] ~]# lvcreate -L 3000M -n lv01 vg01
[[email protected] ~]# lvscan
[[email protected] ~]# lvdisplay
[[email protected] ~]# gfs_mkfs -p lock_dlm -t mycluster:lv01 -j 4 /dev/vg01/lv01
[[email protected] ~]# mount /dev/vg01/lv01 /mnt/1
在两个initiator上做完群集文件系统后，接着做以下步骤.
3> 点击“Submit”，点击“Fence”，创建Fence
4> 创建共享Fence设备，点击“Shared Fence Devices”——>“Add a Fence Device”
在节点上添加fence
5> 创建Failover Domains，“Add a Failover Domain”
6> 创建Resources，点击“Add a Resource”
IP资源
文件系统资源
服务脚本资源
7> 创建Services，点击“Add a Service”
8> 手工切换服务器节点，查看连接状态
节点1上监控日志
节点2上监控日志
