3.分布式文件系统-----fence机制解决Moosefs集群故障

1.服务端配置

[root@foundation15 ~]# yum install fence-virtd-multicast.x86_64 fence-virtd-libvirt.x86_64 -y	#安装
[root@foundation15 ~]# rpm -qa | grep fence	#查看安装的fence有哪些
fence-virtd-multicast-0.4.0-4.el8.x86_64
fence-virtd-libvirt-0.4.0-4.el8.x86_64
libxshmfence-1.3-2.el8.x86_64
fence-virtd-0.4.0-4.el8.x86_64
[root@foundation15 ~]# fence_virtd -c	#fence连接libvirtd配置
一路回车
注意：Interface [br0]:		#【】中不是桥接 输入桥接，是的话，直接回车
