当前IP地址配置：
#rac1
192.168.162.15      rac1
192.168.162.115     rac1-vip
10.10.10.11         rac1-priv
 
#rac2
192.168.162.16      rac2
192.168.162.116     rac2-vip
10.10.10.12         rac2-priv
 
#scan-ip
192.168.162.17      scan-cluster
 
修改后IP地址配置：
#rac1
192.168.162.10      rac1
192.168.162.11      rac1-vip
10.10.10.11         rac1-priv
 
#rac2
192.168.162.12      rac2
192.168.162.13      rac2-vip
10.10.10.12         rac2-priv
 
#scan-ip
192.168.162.14      scan-cluster
 
 
一、关闭集群数据库：
[oracle@rac1 ~]$ srvctl stop database -d racdb
 
二、修改public ip：
1.查看集群ip：
[root@rac1 ~]# oifcfg getif
eth0  192.168.162.0  global  public
eth1  10.10.10.0  global  cluster_interconnect
 
2.删除旧网卡配置：
[root@rac1 ~]# oifcfg delif -global eth0
[root@rac1 ~]# oifcfg getif
eth1  10.10.10.0  global  cluster_interconnect
 
3.重新设置新的公网ip：
[root@rac1 ~]# oifcfg setif -global eth0/192.168.162.0:public
[root@rac1 ~]# oifcfg getif
eth1  10.10.10.0  global  cluster_interconnect
eth0  192.168.162.0  global  public
[root@rac2 ~]# oifcfg getif
eth1  10.10.10.0  global  cluster_interconnect
eth0  192.168.162.0  global  public
 
4.停止集群：
[root@rac1 ~]# crsctl stop crs
[root@rac2 ~]# crsctl stop crs
 
5.修改公网ip地址：
[root@rac1 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
UUID=2e5736c0-2155-43f6-abc8-eb7152e8da1d
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
HWADDR=00:50:56:23:A9:13
IPADDR=192.168.162.10
PREFIX=24
GATEWAY=192.168.162.1
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
 
[root@rac2 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
UUID=42faf68c-5fc6-4584-beb3-10488cf63707
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
HWADDR=00:50:56:39:52:22
IPADDR=192.168.162.11
PREFIX=24
GATEWAY=192.168.162.1
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
 
[root@rac1 ~]# ifdown eth0 && ifup eth0
[root@rac2 ~]# ifdown eth0 && ifup eth0
 
6.启动集群
修改后集群起不来，重启后集群恢复正常
[root@rac1 ~]# crsctl stat res -t

三、修改vip：
1.查看当前vip配置信息：
[root@rac1 ~]# srvctl config nodeapps -a
网络存在: 1/192.168.162.0/255.255.255.0/eth0, 类型 static
VIP 存在: /rac1-vip/192.168.162.11/192.168.162.0/255.255.255.0/eth0, 托管节点 rac1
VIP 存在: /rac2-vip/192.168.162.13/192.168.162.0/255.255.255.0/eth0, 托管节点 rac2
 
[root@rac2 ~]# srvctl config nodeapps -a
网络存在: 1/192.168.162.0/255.255.255.0/eth0, 类型 static
VIP 存在: /rac1-vip/192.168.162.11/192.168.162.0/255.255.255.0/eth0, 托管节点 rac1
VIP 存在: /rac2-vip/192.168.162.13/192.168.162.0/255.255.255.0/eth0, 托管节点 rac2
 
2.停止监听：
[root@rac1 ~]# srvctl stop listener
[root@rac1 ~]# srvctl status listener
监听程序 LISTENER 已启用
监听程序 LISTENER 未运行
[root@rac2 ~]# srvctl status listener
监听程序 LISTENER 已启用
监听程序 LISTENER 未运行
 
3.关闭vip:
[root@rac1 ~]# srvctl stop vip -n rac1
[root@rac1 ~]# srvctl stop vip -n rac2
 
4.修改vip配置：
[root@rac1 ~]# srvctl modify nodeapps -A 192.168.162.11/255.255.255.0/eth0 -n rac1
[root@rac1 ~]# srvctl modify nodeapps -A 192.168.162.13/255.255.255.0/eth0 -n rac2
 
5.启动vip：
[root@rac1 ~]# srvctl start vip -n rac1
[root@rac1 ~]# srvctl start vip -n rac2
 
四、修改scan ip：
1.查看scan配置
[root@rac1 ~]# srvctl config scan
SCAN 名称: scan-cluster, 网络: 1/192.168.162.0/255.255.255.0/eth0
SCAN VIP 名称: scan1, IP: /scan-cluster/192.168.162.17
 
2.关闭SCAN与SCAN Listener：
[root@rac1 ~]# srvctl stop scan_listener
[root@rac1 ~]# srvctl stop scan
 
3.修改SCAN配置：
[root@rac1 ~]# srvctl modify scan -n scan-cluster
 
4.启动SCAN与监听器：
[root@rac1 ~]# srvctl start scan
[root@rac1 ~]# srvctl start scan_listener
 
5.查看修改后的SCAN：
[root@rac1 ~]# srvctl config scan
SCAN 名称: scan-cluster, 网络: 1/192.168.162.0/255.255.255.0/eth0
SCAN VIP 名称: scan1, IP: /scan-cluster/192.168.162.14
