修改rac集群各种ip地址
修改不同网段公网，私网，vip，scan ip步骤
修改ip地址：
1.查看接口配置并修改：
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/oifcfg getif
enp0s3 192.168.6.0 global public 公网ip网段
enp0s8 10.10.10.0 global cluster_interconnect 私网ip网段
删除原公有，私有IP地址:
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/oifcfg delif -global enp0s3
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/oifcfg delif -global enp0s8
重新设置新Public IP：
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/oifcfg setif -global enp0s3/192.168.60.0:public
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/oifcfg setif -global enp0s8/10.10.20.0:cluster_inerconnect
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/oifcfg getif
2.停止has服务：
/oracle/app/11.2.0/grid/bin/crsctl stop has
3.通过操作系统命令修改公有，私有IP地址
linux： vi /etc/sysconfig/network-scripts/ifcfg-enp0s3
systemctl restart network
修改SCAN域名配置（存在DNS域名方式解析，修改域名映射）
修改hosts文件公共IP地址,VIP地址,SCAN地址
vi /etc/hosts
4.启动has：
/oracle/app/11.2.0/grid/bin/crsctl start has
5.查看和修改网络资源
/oracle/app/11.2.0/grid/bin/srvctl config network
Network exists: 1/192.168.6.0/255.255.255.0/enp0s3, type static
/oracle/app/11.2.0/grid/bin/srvctl modify network -k 1 -S 192.168.60.0/255.255.255.0/enp0s3 -v
6.重新配置SCAN VIP和SCAN Listener
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl config scan
SCAN name: rac-scan, Network: 1/192.168.6.0/255.255.255.0/enp0s3
SCAN VIP name: scan1, IP: /rac-scan/192.168.6.254
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl stop scan_listener
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl stop scan
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl remove scan_listener
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl remove scan
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl add scan -n scan(新的scan名称) -k 1 -S 192.168.60.0/255.255.255.0/enp0s3
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl add scan_listener
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl start scan
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl start scan_listener
7.重新配置vip
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl config vip -n rac1
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl config vip -n rac2
VIP exists: /rac1-vip/192.168.6.102/192.168.6.0/255.255.255.0/enp0s3, hosting node rac1
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/crsctl stop resource ora.rac1.vip -f
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/crsctl stop resource ora.rac2.vip -f
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl modify nodeapps -A 192.168.60.101/255.255.255.0/enp0s3 -n rac1
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl modify nodeapps -A 192.168.60.201/255.255.255.0/enp0s3 -n rac2
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/crsctl start resource ora.rac1.vip -f
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/crsctl start resource ora.rac2.vip -f
ps：–crsctl eval stop resource ora.cdbrac.db -unsupported(划重点12c的变化，eval是模拟命令)Doc ID 1966448.1
8.启动本地监听
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl start listener -n rac1
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl start listener -n rac2
9.修改数据库实例参数
alter system set local_listener=’(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.60.101)(PORT=1521))))’ scope=both sid=‘prod1’;
alter system set local_listener=’(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.60.201)(PORT=1521))))’ scope=both sid=‘prod2’;
alter system register;
10.检查资源状态
ifconfig
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl config scan
[root@rac1 ~]# /oracle/app/11.2.0/grid/bin/srvctl config scan_listener
grid lsnrctl status grid l s n r c t l s t a t u s g r i dlsnrctl status listener_scan1
grid$crsctl status res –t
