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

[root@node1 ~]# 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

[root@node1 ~]# 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）

 

[root@node1 ~]# 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

[root@node1 ~]# 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

 

[root@node1 ~]# fence_virsh --ip=10.10.60.10 --username=root --password=root  -x -n node2
Success: Rebooted

或者

[root@node1 ~]# 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
