1、安装集群软件

[node1&node2&node3]# yum install -y lvm2 cifs-utils quota psmisc pcs pacemaker corosync fence-agents-all resource-agents crmsh

2、启动服务并设置开机启动

[node1&node2&node3]# systemctl start pcsd[node1&node2&node3]# systemctl enable pcsd

3、修改集群管理员密码

[node1&node2&node3]# echo Changeme_123 | passwd --stdin haclusterChanging password for user hacluster.New password:Retype new password:passwd: all authentication tokens updated successfully.

4、建立认证

[node1/node2/node3]# pcs cluster auth node1 node2 node3  -u hacluster -p Changeme_123 --forceUsername: haclusterPassword:node1: Authorizednode2: Authorized

5、配置集群

[node1/node2/node3]#  pcs cluster setup --force --name openstack-cluster node1 node2 node3Shutting down pacemaker/corosync services...Redirecting to /bin/systemctl stop pacemaker.serviceRedirecting to /bin/systemctl stop corosync.serviceKilling any remaining services...Removing all cluster configuration files...node1: Succeedednode2: Succeeded

6、启动集群

[node1/node2/node3]# pcs cluster start --allnode2: Starting Cluster...node1: Starting Cluster...

7、设置集群开机启动

[node1/node2/node3]# pcs cluster enable --allnode1: Cluster Enablednode2: Cluster Enabled

8、查看集群状态

[node1/node2/node3]# pcs status clusterCluster Status: Last updated: Wed Jun 23 19:36:55 2017 Last change: Wed Jun 23 19:36:47 2017 Stack: corosync Current DC: node1 (1) - partition with quorum Version: 1.1.12-a14efad 2 Nodes configured 0 Resources configured

查看corosync状态

[node1/node2/node3]# pcs status corosyncMembership information----------------------    Nodeid      Votes Name         1          1 node1 (local)         2          1 node2

禁用stonith和quorum

# pcs property set stonith-enabled=false# pcs property set no-quorum-policy=ignore

配置资源粘性

# pcs property set default-resource-stickiness="INFINITY"# pcs property list 验证# crm_verify -L -V#  pcs property set pe-warn-series-max=1000 \  pe-input-series-max=1000 \  pe-error-series-max=1000 \  cluster-recheck-interval=5min   

设置浮动IP

pcs resource create vip ocf:heartbeat:IPaddr2 ip=172.16.8.50  cidr_netmask=24 op monitor interval=30s
