前期配置免密登入 hosts配置
1.所有节点安装pacemarker每节点执行
# yum install pcs -y
# systemctl enable pcsd
# systemctl start pcsd
2.修改集群密码每节点执行
echo hacluster | passwd --stdin hacluster
3.认证配置节点单节点执行
[root@qigx1 ~]# pcs cluster auth qigx1 qigx2 qigx3 -u hacluster -p hacluster --force
qigx1: Authorized
qigx2: Authorized
qigx3: Authorized
[root@qigx1 ~]#
4.创建pacemarker集群
[root@qigx1 ~]# pcs cluster setup --force --name pcs-cluster qigx1 qigx2 qigx3

qigx2: Cluster Enabled
qigx3: Cluster Enabled
[root@qigx1 ~]# pcs status
Cluster name: pcs-cluster

5.设置集群属性
[root@qigx1 ~]# pcs property set pe-warn-series-max=1000 pe-input-series-max=1000 pe-error-series-max=100
[root@qigx1 ~]# pcs property set cluster-recheck-interval=5
[root@qigx1 ~]# pcs property set stonith-enabled=false
[root@qigx1 ~]# pcs property list
Cluster Properties:
cluster-infrastructure: corosync
cluster-name: pcs-cluster
cluster-recheck-interval: 5
dc-version: 1.1.23-1.el7_9.1-9acf116022
have-watchdog: false
pe-error-series-max: 100
pe-input-series-max: 1000
pe-warn-series-max: 1000
stonith-enabled: false
6.设置vip
pcs resource create vip ocf:heartbeat:IPaddr2 ip=172.21.9.88 cidr_netmask=24 nic=eth0 op monitor interval=30s
7.集群相关操作
# 查看集群状态
# pcs status cluster
# 查看corosync状态；
# pcs status corosync
# 查看集群资源，即查看vip在哪台节点上
# pcs resource
