5.2. 添加一个资源

首先要做的是配置一个IP地址，不管集群服务在哪运行，我们要一个固定的地址来提供服务。在这里我选择192.168.122.101作为浮动IP，给它取一个好记的名字 ClusterIP 并且告诉集群每30秒检查它一次

重要

选择的IP地址不能被节点所占用

# crm configure primitive ClusterIP ocf:heartbeat:IPaddr2 \
     params ip=192.168.122.101 cidr_netmask=32 \
     op monitor interval=30s

The other important piece of information here is ocf:heartbeat:IPaddr2.

This tells Pacemaker three things about the resource you want to add. The first field, ocf, is the standard to which the resource script conforms to and where to find it. The second field is specific to OCF resources and tells the cluster which namespace to find the resource script in, in this case heartbeat. The last field indicates the name of the resource script.

可以运行下面的命令来获得可用的资源类

# crm ra classesheartbeat
lsb ocf / heartbeat pacemakerstonith

找到OCF中Pacemaker和Heartbeat提供的资源脚本，运行下面的命令

# crm ra list ocf pacemaker
ClusterMon   Dummy     Stateful    SysInfo    SystemHealth  controld
ping      pingd
# crm ra list ocf heartbeat

现在检查下IP 资源是不是已经添加了，并且看看是否处在可用状态。

# crm configure shownode pcmk-1
node pcmk-2primitive ClusterIP ocf:heartbeat:IPaddr2 \
    params ip="192.168.122.101" cidr_netmask="32" \
