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
[[email protected] ~]# 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
| [[email protected] ~]# virsh -c qemu+ssh://10.10.60.10/system [email protected]‘s password: Welcome to virsh, the virtualization interactive terminal. Type: ‘help‘ for help with commands virsh # list 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）
| [[email protected] ~]# 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 [[email protected] ~]# ccs_config_validate 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
| [[email protected] ~]# fence_virsh --ip=10.10.60.10 --username=root --password=root -x -n node2 Success: Rebooted 或者 [[email protected] ~]# fence_node node2 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
