安装包（两个节点都要安装）
apt install pacemaker corosync pcs
启用pcsd服务（两个节点都要执行）
systemctl enable --now pcsd
配置hacluster密码（两个节点都要执行）
root@storage01:~# passwd haclusterChanging password for user hacluster. New password: Retype new password: passwd: all authentication tokens updated successfully.
组成cluster，仅在其中一个节点上执行即可，因为我是首次添加，增加–force选项，可以避免不少问题
pcs cluster setup cluster storage01 storage02 --force
开启服务，仅在其中一个节点上执行即可
pcs cluster start --all
启用服务，仅在其中一个节点上执行即可
pcs cluster enable --all
查看集群状态，假如跟下述一样，显示有某个节点offline，可以选择等待一下，我这两个节点花了一点时间才同步的
root@storage01:~# pcs cluster statusCluster Status: Cluster Summary: * Stack: corosync * Current DC: storage01 (version 2.0.3-4b1f869f0f) - partition WITHOUT quorum * Last updated: Tue Dec 2707:42:45 2022 * Last change: Tue Dec 2707:40:34 2022 by hacluster via crmd on storage01 * 2 nodes configured * 0 resource instances configured Node List: * Online: [ storage01 ] * OFFLINE: [ storage02 ] PCSD Status: storage01: Online storage02: Online
等待一会后，再次查看状态
root@storage01:~# pcs cluster statusCluster Status: Cluster Summary: * Stack: corosync * Current DC: storage02eth (version 2.0.3-4b1f869f0f) - partition with quorum * Last updated: Wed Dec 2802:25:19 2022 * Last change: Wed Dec 2802:25:12 2022 by root via cibadmin on storage01eth * 2 nodes configured * 1 resource instance configured Node List: * Online: [ storage01 storage02 ] PCSD Status: storage01: Online storage02: Online
我们可以开始添加浮动IP了（网卡名和label加起来不能超过15个字符，否则会报错）
pcs resource create mgmtd_ip ocf:heartbeat:IPaddr2 ip=10.141.161.19 cidr_netmask=32nic=enp183s0f0 iflabel=mgm op monitor interval=30s
查看状态

可能会提示失败，还缺少这一步
pcs property setstonith-enabled=false
重新查看状态
root@storage01:~# pcs statusCluster name: ha_cluster Cluster Summary: * Stack: corosync * Current DC: storage02eth (version 2.0.3-4b1f869f0f) - partition with quorum * Last updated: Wed Dec 2802:39:45 2022 * Last change: Wed Dec 2802:39:23 2022 by root via cibadmin on storage01eth * 2 nodes configured * 1 resource instance configured Node List: * Online: [ storage01 storage02 ] Full List of Resources: * mgmtd_ip (ocf::heartbeat:IPaddr2): Started storage01 Daemon Status: corosync: active/enabled pacemaker: active/enabled pcsd: active/enabled
接下来查看ip，应该浮动ip就会存在了
