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 hacluster
Changing 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 --force
Username: hacluster
Password:
node1: Authorized
node2: Authorized

5、配置集群

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

6、启动集群

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

7、设置集群开机启动

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

8、查看集群状态

[node1/node2/node3]# pcs status cluster
Cluster 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 corosync
Membership 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
