KVM环境搭建RHCS
一、环境Hypervisor：RHEL 6.3
IP：10.10.60.10 login：root passwd：root
Guest OS：CentOS 6.3 两台
node1 IP：10.10.60.16 login：root passwd：root
node2 IP：10.10.60.55 login：root passwd：root
二、配置
1、修改hosts文件
# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.10.60.16 node1
10.10.60.55 node2
2、同步ssh key
# scp -r /root/.ssh/ node2:/root/
3、安装RHCS套件
# for i in cman ricci ;do rpm -qa | grep $i;done
cman-3.0.12.1-32.el6.x86_64
ricci-0.16.2-55.el6.x86_64
4、测试Hypervisor的libvirt连接情况
# virsh -c qemu+ssh://10.10.60.10/system
root@10.10.60.10's password:
Welcome to virsh, the virtualization interactive terminal.
Type:'help' for help with commands
'quit' to quit
virsh # list
Id Name State
----------------------------------------------------
2 cLient_App running
14 node1 running
18 node2 running
virsh #
出现虚机信息，说明libvirt连接成功，可用于fence
5、编辑cluster.conf文件（记得同步到node2）
# cat /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster config_version="12" name="kvm_fence">
<clusternodes>
<clusternode name="node1" nodeid="1">
<fence>
<method name="virsh">
<device action="reboot" name="virsh" port="node1"/>
</method>
</fence>
</clusternode>
<clusternode name="node2" nodeid="2">
<fence>
<method name="virsh">
<device action="reboot" name="virsh" port="node2"/>
</method>
</fence>
</clusternode>
</clusternodes>
<cman expected_votes="1" two_node="1"/>
<fencedevices>
<fencedevice agent="fence_virsh" ipaddr="10.10.60.10" login="root" name="virsh" passwd="root"/>
</fencedevices>
</cluster>
验证cluster.conf语句
# ccs_config_validate
Configuration validates
备注：cluster.conf文件中fencedevice agent部分参数由man fence_virsh可知
6、测试节点手动fence
# fence_virsh --ip=10.10.60.10 --username=root --password=root-x -n node2
Success: Rebooted
或者
# fence_node node2
fence node2 success
fence_node命令会自动取fence_virsh中相关参数
7、服务开机启动
# chkconfig cman on
# chkconfig ricci on
