error: unpack_resources: Resource start-up disabled since no STONITH resources have been defined
error: unpack_resources: Either configure some or disable STONITH with the stonith-enabled option
error: unpack_resources: NOTE: Clusters with shared data need STONITH to ensure data integrity
Errors found during check: config not valid
-V may provide more details
######禁用Stonith并查看
[root@nod1 ~]# crm configure property stonith-enabled=false
[root@nod1 ~]# crm configure show
node nod1.allen.com
node nod2.allen.com
property $id="cib-bootstrap-options" \
dc-version="1.1.8-7.el6-394e906" \
cluster-infrastructure="classic openais (with plugin)" \
expected-quorum-votes="2" \
stonith-enabled="false"
2、查看当前的集群系统支持的类型
[root@nod1 ~]# crm ra classes
lsb
ocf / heartbeat linbit pacemaker RedHat
service
stonith
注释：linbit 资源类型只有安装DRBD服务才会有
3、如何查看某种类型下所用可用的资源代理列表？
crm ra list lsb
crm ra list ocf heartbeat
crm ra list ocf pacemaker
crm ra list stonith
crm ra list ocf linbit
4、配置VIP资源与Mysqld资源
[root@nod1 ~]# crm #进入crm交互模式
crm(live)# configure
crm(live)configure# property no-quorum-policy="ignore"
crm(live)configure#primitive WebIP IPaddr params ip=172.18.109.238 nic="eth0:0" cidr_netmask=26
crm(live)configure#primitive myserver lsb:mysql op monitor interval=60 timeout=60 on-fail=restart
crm(live)configure# verify #检查语法错误
crm(live)configure# commit #提交
crm(live)configure# show #查看配置
5、配置DRBD主从资源
crm(live)configure#primitive mysqldrbd ocf:linbit:drbd params drbd_resource="mysql" op monitor interval="30s" role="Master" timeout="30s" op monitor interval="40s" role="Slave" timeout="30s" op start interval="0" timeout="240" op stop interval="0" timeout="100"
crm(live)configure#ms ms_mysqldrbd mysqldrbd meta master-max="1" master-node-max="1" clone-max="2" clone-node-max="1" notify="true"
6、定义一个文件系统资源
crm(live)configure#primitive mysqlfs ocf:heartbeat:Filesystem params device="/dev/drbd0" directory="/data/mysql" fstype="ext4" op start timeout="60s" op stop timeout="60s"
7、配置资源组合资源约束
目的是为让mysql和drbd资源在同一个节点，而且drbd必须先于mysql启动。
crm(live)configure#group lnmp WebIP webnfs mysqlfs myserver WebSite #这里新增加了web和webnfs资源，目的是为创建高可用的lnmp，如果不需要去掉web和webnfs即可。注意资源顺序。
crm(live)configure# colocation lnmp_with_ms_mysqldrbd inf: lnmp ms_mysqldrbd:Master #mysql和drbd资源在同一个节点
crm(live)configure#order lnmp_after_ms_mysqldrbd inf: ms_mysqldrbd:promote lnmp:start #drbd先于lnmp启动
8、查看服务状态如下：
[root@nod1 ~]# crm status
Master/Slave Set: ms_mysqldrbd [mysqldrbd]
Masters: [ node2.test.com ]
Slaves: [ node1.test.com ]
Resource Group: lnmp
WebIP (ocf::heartbeat:IPaddr): Started node2.test.com
webnfs (ocf::heartbeat:Filesystem): Started node2.test.com
mysqlfs (ocf::heartbeat:Filesystem): Started node2.test.com
myserver (lsb:mysql): Started node2.test.com
