修改Virtual IP
1.停止vip资源
[root@rac1 bin]# ./crsctl stop resource ora.rac1.vip -f

验证修改后的状态
这里我在节点2上进行验证
[grid@rac2 ~]$ crs_stat -t

修改scan ip
1.停止scan_listener scan
[root@rac1 bin]# ./srvctl stop scan_listener

修改Virtual IP
1.停止vip资源
[root@rac1 bin]# ./crsctl stop resource ora.rac1.vip -f
[root@rac1 bin]# ./crsctl stop resource ora.rac2.vip -f

2.查看vip状态
[root@rac1 bin]# ./crsctl stat res -t

3.修改vip地址
[root@rac1 bin]# ./srvctl modify nodeapps -A 192.168.13.9/255.255.255.0/ens33 -n rac1
[root@rac1 bin]# ./srvctl modify nodeapps -A 192.168.13.11/255.255.255.0/ens33 -n rac2

4.启动vip资源
[root@rac1 bin]# ./crsctl start resource ora.rac1.vip -f
CRS-2672: Attempting to start 'ora.rac1.vip' on 'rac1'
CRS-2676: Start of 'ora.rac1.vip' on 'rac1' succeeded
CRS-2672: Attempting to start 'ora.LISTENER.lsnr' on 'rac1'
CRS-2676: Start of 'ora.LISTENER.lsnr' on 'rac1' succeeded
[root@rac1 bin]# ./crsctl start resource ora.rac2.vip -f
CRS-2672: Attempting to start 'ora.rac2.vip' on 'rac2'
CRS-2676: Start of 'ora.rac2.vip' on 'rac2' succeeded
CRS-2672: Attempting to start 'ora.LISTENER.lsnr' on 'rac2'
CRS-2676: Start of 'ora.LISTENER.lsnr' on 'rac2' succeeded
启动vip资源后本地监听就已经启动了  下面的步骤可以不执行

5.启动本地监听
./srvctl start listener -n rac1
./srvctl start listener -n rac1

6.查看本地监听
[root@rac1 bin]# ./srvctl status listener -n rac1
Listener LISTENER is enabled on node(s): rac1
Listener LISTENER is running on node(s): rac1
[root@rac1 bin]# ./srvctl status listener -n rac2
Listener LISTENER is enabled on node(s): rac2
Listener LISTENER is running on node(s): rac2

7.查看网口配置信息
[grid@rac1 ~]$ oifcfg getif
ens33  192.168.13.0  global  public
ens34  2.2.2.0  global  cluster_interconnect

修改Public Ip 和Private IP
1.在任意节点上修改
这里我以节点1上面进行操作

修改scan ip
1.停止scan_listener scan
[root@rac1 bin]# ./srvctl stop scan_listener
[root@rac1 bin]# ./srvctl stop scan

2.删除scan_listener scan
[root@rac1 bin]# ./srvctl remove scan_listener -f
[root@rac1 bin]# ./srvctl remove scan -f      

3.添加scan_listener scan
[root@rac1 bin]# ./srvctl add scan -n rac-scan -k 1 -S 192.168.13.0/255.255.255.0/ens33
PRCN-3008 : Failed to add or use registered network 1 with network subnet '192.168.13.0' because the network was already registered for network subnet '192.168.133.0'
说明:-k 1 会报错，是因为之前已经使用过
[root@rac1 bin]# ./srvctl add scan -n rac-scan -k 2 -S 192.168.13.0/255.255.255.0/ens33
[root@rac1 bin]# ./srvctl config scan
SCAN name: rac-scan, Network: 2/192.168.13.0/255.255.255.0/ens33
SCAN VIP name: scan1, IP: /rac-scan/192.168.13.77
[root@rac1 bin]# ./srvctl add scan_listener

4.启动scan_listener scan
[root@rac1 bin]# ./srvctl start scan
[root@rac1 bin]# ./srvctl start scan_listener

RAC修改IP这个操作本身也只有几步操作，但是它涉及到OCR。所以要格外小心。一般来说，如果不是必须要修改的 ...

PRIF-31: Failed to delete the specified network interface because it is the last private interface
这里不允许删除最后一个私有接口，可以先添加一个私有接口再删除
[root@rac1 bin]# ./oifcfg setif -global ens34/2.2.2.0:cluster_interconnect
[root@rac1 bin]# ./oifcfg getif
ens34  1.1.1.0  global  cluster_interconnect

3.修改ip地址并测试（所有节点都要修改）
/etc/hosts
/etc/sysconfig/network-scripts/ifcfg-ens33
/etc/sysconfig/network-scripts/ifcfg-ens34

4.在所有节点上重新启动服务
[root@rac1 bin]# ./crsctl start cluster -all

RAC修改IP这个操作本身也只有几步操作，但是它涉及到OCR。所以要格外小心。一般来说，如果不是必须要修改的话，尽量不要去修改OCR 的东西。稳定第一。
在做之前，要手动对OCR进行一个备份，这样即使修改失败，也能还原回来。
另外，Public/Private对应的的主机名不能更改，如果确实需要更改主机名，需要重新安装CRS。

1.查看ocr的备份
[root@rac1 bin]# ./ocrconfig -showbackup

2.备份ocr
[root@rac1 bin]# ./ocrconfig -manualbackup
rac2     2020/02/26 20:15:42     /u01/app/11.2.0/grid/cdata/rac/backup_20200226_201542.ocr
[root@rac1 bin]# ./ocrconfig -showbackup
PROT-24: Auto backups for the Oracle Cluster Registry are not available
rac2     2020/02/26 20:15:42     /u01/app/11.2.0/grid/cdata/rac/backup_20200226_201542.ocr

3.关闭数据库
[root@rac1 bin]# ./srvctl stop database -d rac
