RAC 更改主机名及IP地址_m0_37933891的博客-程序员宝宝
技术标签： RAC
由于安装RAC时脚本执行顺序错了，导致实例orcl1装到了rac2节点上，orcl2装到了rac1节点上，看起来很别扭，趁这个机会练习下更改主机名和IP地址。
原IP及主机名设置：
#public IP
172.12.1.11 rac1.oracle.com rac1
172.12.1.12 rac2.oracle.com rac2
#private IP
10.10.10.1 rac1-priv.oracle.com rac1-priv
10.10.10.2 rac2-priv.oracle.com rac2-priv
#vritual IP
172.12.1.21 rac1-vip.oracle.com rac1-vip
172.12.1.22 rac2-vip.oracle.com rac2-vip
#scan IP
172.12.1.31 rac-scan.oracle.com rac-scan
修改后的设置：
#public IP
172.12.1.101 node1.oracle.com node1
172.12.1.102 node2.oracle.com ndoe2
#private IP
10.10.10.11 node1-priv.oracle.com node1-priv
10.10.10.12 node2-priv.oracle.com node2-priv
#vritual IP
172.12.1.201 node1-vip.oracle.com node1-vip
172.12.1.202 node2-vip.oracle.com node2-vip
#scan IP
172.12.1.110 node-scan.oracle.com node-scan修改流程：
删除rac2节点，改rac2节点主机名、IP地址，两个节点的/etc/hosts，再把此节点加入删集群；删除rac1节点，改rac1节点主机名、IP地址，两个节点的/etc/hosts，再把此节点加入集群。
具体步骤：
1、检查2个节点是否是active和Unpinned ，如果是pinned的，用crsctl unpin css
以下是关于pinned的解释：
When Oracle Clusterware 11g release 11.2 is installed on a cluster with no previous Oracle software version,
it configures cluster nodes dynamically, which is compatible with Oracle Database Release 11.2 and later,
but Oracle Database 10g and 11.1 require a persistent configuration.
This process of association of a node name with a node number is called pinning.
Note:
During an upgrade, all cluster member nodes are pinned automatically, and no manual pinning is required for
existing databases. This procedure is required only if you install older database versions after installing
Oracle Grid Infrastructure release 11.2 software.
pinned的实验过程：
[root@rac2 ~]# /u01/app/11.2.0/grid/bin/crsctl pin css -n rac2
CRS-4664: Node rac2 successfully pinned.
[grid@rac2 ~]$ olsnodes -n -s -t
rac2 1 Active Pinned
rac1 2 Active Unpinned
[root@rac2 ~]# /u01/app/11.2.0/grid/bin/crsctl unpin css -n rac2
CRS-4667: Node rac2 successfully unpinned.
[grid@rac2 ~]$ olsnodes -n -s -t
rac2 1 Active Unpinned
rac1 2 Active Unpinned2、root用户在rac2节点 GRID_HOME 上执行
[root@rac2 ~]# /u01/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig -force --删除集群配置，如果是最后一个节点/u01/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig -force -lastnode

[root@rac1 ~]# /u01/app/11.2.0/grid/bin/crsctl delete node -n rac2
CRS-4661: Node rac2 successfully deleted.4、在要删除的节点上用grid用户执行，更新节点信息
[grid@rac2 ~]$ echo $ORACLE_HOME
/u01/app/11.2.0/grid
[grid@rac2 ~]$ /u01/app/11.2.0/grid/oui/bin/runInstaller -updateNodeList ORACLE_HOME=/u01/app/11.2.0/grid "CLUSTER_NODES={rac2}" CRS=TRUE -silent -local

The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /u01/app/oraInventory
'UpdateNodeList' was successful.5、清理要删除节点的Clusterware home安装文件，grid用户执行：
$ Grid_home/deinstall/deinstall –local
注意一定要添加 -local 选项 ，否者会删除 所有节点的Clusterware home 安装目录.
期间会有交互，一直回车用默认值，最后一个选择[y]继续。
[grid@rac2 deinstall]$ ./deinstall -local

[grid@rac2 deinstall]$ 6、使用grid用户在rac1节点执行以下命令,更新节点信息：
[grid@rac1 ~]$ /u01/app/11.2.0/grid/oui/bin/runInstaller -updateNodeList ORACLE_HOME=/u01/app/11.2.0/grid "CLUSTER_NODES={rac1}" CRS=TRUE -silent -local

[root@node1 ~]# cat /etc/sysconfig/network

NETWORKING_IPV6=no
HOSTNAME=node1
[root@node1 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.

172.12.1.31 rac-scan.oracle.com rac-scan9、在rac1上使用grid用户检查节点2是否满足
[grid@rac1 ~]$ cluvfy stage -pre nodeadd -n node1 -fixup -fixupdir /tmp -verbose

Pre-check for node addition was unsuccessful on all the nodes. 因为主机名修改了，两节点间grid用户信任关系需要重建
/u01/app/11.2.0/grid/deinstall/sshUserSetup.sh -user grid -hosts rac1 node1 -noPromptPassphrase 10、添加Node1节点，在rac1上执行下面的命令，使用Grid用户，但在此之前需先修改addNode.sh文件
[grid@rac1 ~]$ $ORACLE_HOME/oui/bin/addNode.sh "CLUSTER_NEW_NODES={node1}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={node1-vip}" -silent一些无关紧要的小问题检查不通过，在图形界面安装时是可以忽略的，这里是不能直接忽略的，需要修改一下addNode.sh文件
#!/bin/sh
OHOME=/u01/app/11.2.0/grid
INVPTRLOC=$OHOME/oraInst.loc
EXIT_CODE=0
ADDNODE="$OHOME/oui/bin/runInstaller -addNode -invPtrLoc $INVPTRLOC ORACLE_HOME=$OHOME $*"
if [ "$IGNORE_PREADDNODE_CHECKS" = "Y" -o ! -f "$OHOME/cv/cvutl/check_nodeadd.pl" ]
then
$ADDNODE
EXIT_CODE=$?;
else
CHECK_NODEADD="$OHOME/perl/bin/perl $OHOME/cv/cvutl/check_nodeadd.pl -pre ORACLE_HOME=$OHOME $*"
$CHECK_NODEADD
EXIT_CODE=$?;
EXIT_CODE=0 ##在这里添加一行，用于忽略一些小错误
if [ $EXIT_CODE -eq 0 ]
then
$ADDNODE
EXIT_CODE=$?;
fi
fi
exit $EXIT_CODE ;
执行结束后，在结尾有提示需用root用户在node1上执行脚本：
WARNING:
The following configuration scripts need to be executed as the "root" user in each cluster node.
/u01/app/11.2.0/grid/root.sh #On nodes node1

[grid@node1 grid]$ /u01/app/11.2.0/grid/deinstall/sshUserSetup.sh -user grid -hosts rac1 node1 -noPromptPassphrase重新执行[root@node1 ~]# /u01/app/11.2.0/grid/root.sh
修改实例所在节点：
[grid@node1 grid]$ srvctl modify instance -d orcl -i orcl1 -n node1
[grid@node1 grid]$ srvctl status database -d orcl
Instance orcl1 is not running on node node1
Instance orcl2 is running on node rac1
[grid@node1 grid]$ srvctl start instance -d orcl -i orcl1
[grid@node1 grid]$ srvctl status database -d orcl
Instance orcl1 is running on node node1
Instance orcl2 is running on node rac1删除rac1节点，修改为node2，重复以上步骤。
上述步骤一步都不可省略，否则会出错，在操作中遇到问题就检查上述步骤是否做错或者有遗漏。
