目标：
修改数据库一个节点的vip
初始信息如下：
hostname:ggjjzhzzdb02
vip:192.168.19.10/255.255.255.0
修改后vip信息如下：
vip:192.168.19.12/255/255.255.0
1，操作系统版本信息
[root@ggjjzhzzdb01 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.2 (Maipo)
2，查看/etc/hosts信息
[grid@ggjjzhzzdb02 ~]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.19.7 ggjjzhzzdb01
192.168.19.9 ggjjzhzzdb02
192.168.19.6 ggjjzhzzdb01-vip
192.168.19.10 ggjjzhzzdb02-vip
192.168.1.19 ggjjzhzzdb01-pri
192.168.1.20 ggjjzhzzdb02-pri
192.168.19.11 ggjjzhzzdb-scan
3，使用grid用户查看现在vip配置情况
[grid@ggjjzhzzdb02 ~]$ srvctl config nodeapps -a
Network exists: 1/192.168.19.0/255.255.255.0/bond0, type static
VIP exists: /ggjjzhzzdb01-vip/192.168.19.6/192.168.19.0/255.255.255.0/bond0, hosting node ggjjzhzzdb01
VIP exists: /ggjjzhzzdb02-vip/192.168.19.10/192.168.19.0/255.255.255.0/bond0, hosting node ggjjzhzzdb02
4，查看vip状态
[grid@ggjjzhzzdb02 ~]$ crs_stat -t | grep vip
ora....b01.vip ora....t1.type ONLINE ONLINE ggjj...db01
ora....b02.vip ora....t1.type ONLINE ONLINE ggjj...db02
ora.scan1.vip ora....ip.type ONLINE ONLINE ggjj...db01
使用crsctl stat res -t 显示vips的状态为Online
使用ifconfig -a 查看vip逻辑网卡对应物理网卡
[grid@ggjjzhzzdb02 ~]$ ifconfig -a
bond0: flags=5187 mtu 1500

TX packets 3682761 bytes 3085923418 (2.8 GiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
开始修改
1，停止nodeapps资源
[grid@ggjjzhzzdb02 ~]$ srvctl stop instance -d ggjjzhzzdb -n ggjjzhzzdb02
[grid@ggjjzhzzdb02 ~]$ srvctl stop vip -n ggjjzhzzdb02 -f
2，验证VIP状态处于OFFLINE状态，并且不再绑定到公共网卡
[grid@ggjjzhzzdb02 ~]$ ifconfig -a
bond0: flags=5187 mtu 1500
inet 192.168.19.9 netmask 255.255.255.240 broadcast 192.168.19.15
inet6 fe80::84b1:7bff:feac:2d83 prefixlen 64 scopeid 0x20

TX packets 3704086 bytes 3104892925 (2.8 GiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
3，修改/etc/hosts相关信息
[root@ggjjzhzzdb02 ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.19.7 ggjjzhzzdb01
192.168.19.9 ggjjzhzzdb02
192.168.19.6 ggjjzhzzdb01-vip
192.168.19.12 ggjjzhzzdb02-vip
192.168.1.19 ggjjzhzzdb01-pri
192.168.1.20 ggjjzhzzdb02-pri
192.168.19.11 ggjjzhzzdb-scan
4，用户root用户修改vip
srvctl modify nodeapps -n ggjjzhzzdb02 -A ggjjzhzzdb02-vip/255.255.255.0/bond0
验证修改成功
[grid@ggjjzhzzdb02 ~]$ srvctl config nodeapps -a
Network exists: 1/192.168.19.0/255.255.255.0/bond0, type static
VIP exists: /ggjjzhzzdb01-vip/192.168.19.6/192.168.19.0/255.255.255.0/bond0, hosting node ggjjzhzzdb01
VIP exists: /ggjjzhzzdb02-vip/192.168.19.12/192.168.19.0/255.255.255.0/bond0, hosting node ggjjzhzzdb02
启动nodeapp及其他状态
[grid@ggjjzhzzdb02 ~]$ srvctl start vip -n ggjjzhzzdb02
[grid@ggjjzhzzdb02 ~]$ srvctl start listener -n ggjjzhzzdb02
[grid@ggjjzhzzdb02 ~]$ srvctl start instance -d ggjjzhzzdb -i ggjjzhzz2
验证VIP状态为ONLINE并且已经绑定到集群公共网卡
crsctl stat res -t
[grid@ggjjzhzzdb02 ~]$ ifconfig -a
bond0: flags=5187 mtu 1500
inet 192.168.19.9 netmask 255.255.255.240 broadcast 192.168.19.15
inet6 fe80::84b1:7bff:feac:2d83 prefixlen 64 scopeid 0x20
ether 6c:92:bf:4c:73:35 txqueuelen 0 (Ethernet)
RX packets 215380 bytes 52532880 (50.0 MiB)
RX errors 0 dropped 82599 overruns 0 frame 0
TX packets 25107 bytes 2689898 (2.5 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
bond0:1: flags=5187 mtu 1500
inet 192.168.19.12 netmask 255.255.255.240 broadcast 192.168.19.15
ether 6c:92:bf:4c:73:35 txqueuelen 0 (Ethernet)
如果集群其他节点也需要修改，按照上面步骤进行修改。
备注：
查看instance name 及 node name
SQL> select instance_name,HOST_NAME from gv$instance;
INSTANCE_NAME HOST_NAME
