1、查看配置信息 crm(live)# configure crm(live)configure# show node node1 node node2 property cib-bootstrap-options: \ dc-version=1.1.14-8.el6_8.2-70404b0 \ cluster-infrastructure="classic openais (with plugin)" \ expected-quorum-votes=2 2、因为无stonith设备,所以禁用stonith,stonith的值为布尔类型,true和false crm(live)configure# property stonith-enabled=false 3、提交配置 crm(live)configure# commit 4、介绍node子命令 crm(live)configure# cd .. #返回上一级 crm(live)# node crm(live)node# help attribute Manage attributes clearstate Clear node state #清理当前node的状态信息 delete Delete node #删除节点 fence Fence node maintenance Put node into maintenance mode online Set node online #将当前节点重新上线,standby转为online ready Put node into ready mode server Show node hostname or server address show Show node #显示当前所有节点 standby Put node into standby #将当前节点转为备用 status Show nodes' status as XML status-attr Manage status attributes utilization Manage utilization attributes cd Navigate the level structure help Show help (help topics for list of topics) ls List levels and commands #指明级别和子命令列出当前可用节点 quit Exit the interactive shell up Go back to previous level 5、介绍resource子命令 crm(live)# resource crm(live)resource# help ban Ban a resource from a node #禁止资源在一个节点 cleanup Cleanup resource status #清理资源状态 constraints Show constraints affecting a resource #显示影响资源的约束 demote Demote a master-slave resource #降级主从资源 failcount Manage failcounts #管理员错误状态统计数据 locate Show the location of resources #显示资源的位置 maintenance Enable/disable per-resource maintenance mode #启用/禁用每个资源维护模式 manage Put a resource into managed mode #资源定义为可被管理状态 meta Manage a meta attribute #管理meta 属性 move Move a resource to another node #将资源移动到另一个节点 operations Show active resource operations #显示活动的资源的操作 param Manage a parameter of a resource #管理资源参数 promote Promote a master-slave resource refresh Refresh CIB from the LRM status reprobe Probe for resources not started by the CRM restart Restart resources #重启一个资源 scores Display resource scores #查看资源 secret Manage sensitive parameters start Start resources #开启一个资源 status Show status of resources #资源当前状态 stop Stop resources #停止一个资源 trace Start RA unmanage Put a resource into unmanaged mode #资源定义为不可被管理状态 untrace Stop RA tracing utilization Manage a utilization attribute 6、介绍资源代理RA子命令 crm(live)# ra crm(live)ra# help classes List classes and providers #列出资源代理类型 info Show meta data for a RA #显示资源代理的帮助信息 list List RA for a class (and provider) #列出资源代理类型中所拥有的资源代理 providers Show providers for a RA and a class validate Validate parameters for RA 7、介绍configure子命令 node define a cluster node #定义一个集群节点 primitive define a resource #定义资源 monitor add monitor operation to a primitive #对一个资源添加监控选项(如超时时间,启动失败后的操作) group define a group #定义一个组类型(包含一个或多个资源,这些资源可通过“组”这个资源统一进行调度) clone define a clone #定义一个克隆类型(可以在同一个集群内的多个节点运行多份克隆) ms define a master-slave resource #定义一个主从类型(集群内的节点只能有一个运行主资源,其它从的做备用) rsc_template define a resource template #定义一个资源模板 location a location preference #定义位置约束优先级(默认运行于那一个节点(如果位置约束的值相同,默认倾向性那一个高,就在那一个节点上运行)) colocation colocate resources #排列约束资源(多个资源在一起的可能性) order order resources #顺序约束,定义资源在同一个节点上启动时的先后顺序 rsc_ticket resources ticket dependency property set a cluster property #设置集群属性 rsc_defaults set resource defaults #设置资源默认属性(粘性) fencing_topology node fencing order #隔离节点顺序 role define role access rights #定义角色的访问权限 user define user access rights #定义用用户访问权限 op_defaults set resource operations defaults #设置资源默认选项 schema set or display current CIB RNG schema show display CIB objects #显示集群信息库对 edit edit CIB objects #编辑集群信息库对象(vim模式下编辑) filter filter CIB objects #过滤CIB对象 delete delete CIB objects #删除CIB对象 default-timeouts set timeouts for operations to minimums from the meta-data rename rename a CIB object #重命名CIB对象 modgroup modify group #改变资源组 refresh refresh from CIB #重新读取CIB信息 erase erase the CIB #清除CIB信息 ptest show cluster actions if changes were committed rsctest test resources as currently configured cib CIB shadow management cibstatus CIB status management and editing template edit and import a configuration from a template commit commit the changes to the CIB #将更改后的信息提交写入CIB verify verify the CIB with crm_verify #CIB语法验证 upgrade upgrade the CIB to version 1.0 save save the CIB to a file #将当前CIB导出到一个文件中(导出的文件存于切换crm 之前的目录) load import the CIB from a file #从文件内容载入CIB
但谈何容易。
