heartbeat (corosync) 支持多节点集群
加存储：drbd(前提：做好drbd)
crm
首先停掉资源
primitive drbddata ocf:linbit:drbd params drbd_resource=example op monitorinterval=60s
ms drbddataclone drbddata meta master-max=1 master-node-max=1 clone-max=2clon-node-max=1 notify=true
commit
primitive sqlfs ocf:heartbeat:Filesystem params device=/dev/drbd1directory=/var/lib/mysql fstype=ext4 op monitor interval=60s
colocation sqlfs-with-drbddata inf:sqlfs drbddataclone:Master
order sqlfs-after-drbddata inf:drbddataclone:promote sqlfs:start
commit
primitive mysql lsb:mysqld op monitor interval=60s
group musqlgroup vip sqlfs mysql
pacemaker+lvs:
前提：两台real server正常 两台调度机正常
crm
之前资源删除：
stop mysqlgroup
stop drbddataclone
delete mysqlgroup
delete mysql
delete drbddataclone
delete sqlfs
delete sqlfs-with-drbddata
delete sqlfs-after-drbddata
delete drbddata
commit
primitive lvs lsb:ldirectord op monitor interval=30s
group mylvs vip lvs
