Oracle 11g RAC重新添加节点

      环境：
            suse 11sp4
          Oracle 11.2.0.4.180116 RAC
    安装Oracle11g rac过程中，由于主机硬件原因，导致节点1操作系统需要重新安装，目前集群已经全部安装完成，尚未创建数据库。
    详细操作过程如下：


grid@XXXXXrac2:~> olsnodes -s -t
XXXXXrac1       Inactive        Unpinned
XXXXXrac2       Active  Unpinned

--删除一节点：
/oracle/xxxx/grid/bin/crsctl delete node -n XXXXXrac1（二节点root执行）
XXXXXrac2:~ # /oracle/xxxx/grid/bin/crsctl delete node -n XXXXXrac1
CRS-4661: Node XXXXXrac1 successfully deleted.
XXXXXrac2:~ # 




grid@XXXXXrac2:~> olsnodes -s -t
XXXXXrac2       Active  Unpinned


--清除一节点VIP信息
XXXXXrac2:~ # /oracle/xxxx/grid/bin/srvctl stop vip -i XXXXXrac1 -f
XXXXXrac2:~ # /oracle/xxxx/grid/bin/srvctl remove vip -i XXXXXrac1 -f




二节点更新inventory信息
grid@XXXXXrac2:~> /oracle/xxxx/grid/oui/bin/runInstaller -updateNodeList ORACLE_HOME=/oracle/xxxx/grid  "CLUSTER_NODES=XXXXXrac2" CRS=TRUE -silent
Starting Oracle Universal Installer...


Checking swap space: must be greater than 500 MB.   Actual 32767 MB    Passed

The inventory is located at /oracle/app/oraInventory
'UpdateNodeList' was successful.




oracle@XXXXXrac2:~>  /oracle/app/oracle/product/11.2.0/db_1/oui/bin/runInstaller -updateNodeList ORACLE_HOME=/oracle/app/oracle/product/11.2.0/db_1 "CLUSTER_NODES=XXXXXrac2"

检查整个删除过程


grid@XXXXXrac2:~> cluvfy stage -post nodedel -n XXXXXrac1 -verbose


Performing post-checks for node removal 


Checking CRS integrity...


Clusterware version consistency passed
The Oracle Clusterware is healthy on node "XXXXXrac2"


CRS integrity check passed
Result: 
Node removal check passed


Post-check for node removal was successful.








==========添加节点
主机安装操作系统。
配置集群安装基础环境






--配置ssh互信
grid、oracle 用户ssh互信配置
mkdir ~/.ssh
chmod 755 ~/.ssh
/usr/bin/ssh-keygen -t rsa
/usr/bin/ssh-keygen -t dsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
ssh XXXXXrac2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
ssh XXXXXrac2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
scp ~/.ssh/authorized_keys XXXXXrac2:~/.ssh






--添加grid
[export IGNORE_PREADDNODE_CHECKS=Y  #可选]
grid@XXXXXrac2:~> /oracle/xxxx/grid/oui/bin/addNode.sh "CLUSTER_NEW_NODES={XXXXXrac1}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={XXXXXrac1-vip}" 


Performing pre-checks for node addition 


Checking node reachability...
Node reachability check passed from node "XXXXXrac2"




Checking user equivalence...
User equivalence check passed for user "grid"

WARNING:A new inventory has been created on one or more nodes in this session. However, it has not yet been registered as the central inventory of this system. 
To register the new inventory please run the script at '/oracle/app/oraInventory/orainstRoot.sh' with root privileges on nodes 'XXXXXrac1'.
If you do not register the inventory, you may not be able to update or patch the products you installed.
The following configuration scripts need to be executed as the "root" user in each new cluster node. Each script in the list below is followed by a list of nodes.
/oracle/app/oraInventory/orainstRoot.sh #On nodes XXXXXrac1
/oracle/xxxx/grid/root.sh #On nodes XXXXXrac1
To execute the configuration scripts:
    1. Open a terminal window
    2. Log in as "root"
    3. Run the scripts in each cluster node
    
The Cluster Node Addition of /oracle/xxxx/grid was successful.
