1.查看原来的数据库IP 信息
[oracle@rac2 ~]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.3.180 rac1
10.10.10.180 rac1-priv
192.168.3.182 rac1-vip
192.168.3.181 rac2
10.10.10.181 rac2-priv
192.168.3.183 rac2-vip
192.168.3.184 rac-scan
2.查看当前数据库状态
[grid@rac2 ~]$ crsctl stat res -t

3.看当前节点信息
[grid@rac2 ~]$ srvctl config scan
SCAN name: rac-scan, Network: 1
Subnet IPv4: 192.168.3.0/255.255.255.0/enp0s3, static
Subnet IPv6:
SCAN 1 IPv4 VIP: 192.168.3.184
SCAN VIP is enabled.
4.停掉应用，禁用listener，关掉本地监听
[grid@rac2 ~]$ srvctl disable listener
[grid@rac2 ~]$
[grid@rac2 ~]$ srvctl stop listener
[grid@rac2 ~]$ srvctl status listener
Listener LISTENER is disabled
Listener LISTENER is not running
[grid@rac2 ~]$
5.关库
[oracle@rac2 ~]$ cd /u01/app/19.3.0/grid/bin/
[oracle@rac2 ~]$ srvctl enable database -d prodb
[oracle@rac2 bin]$ srvctl stop database -d prodb
6关掉 远程监听
[grid@rac2 ~]$servctl disable scan_listener
[grid@rac2 ~]$ srvctl stop scan_listener
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl disable scan
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl stop scan
[root@rac2 ~]#/u01/app/19.3.0/grid/bin/srvctl status scan
7.关集群
/u01/app/19.3.0/grid/bin/crsctl stop crs
8.修改ip
192.168.6.21 rac1
10.10.10.20 rac1-priv
192.168.6.22 rac1-vip
192.168.6.20 rac2
10.10.10.21 rac2-priv
192.168.6.23 rac2-vip
192.168.6.24 rac-scan
[root@rac2 ~]# vi /etc/sysconfig/network-scripts/ifcfg-enp0s3
[root@rac2 ~]# vi /etc/sysconfig/network-scripts/ifcfg-enp0s8
[root@rac2 ~]#
[root@rac2 ~]# service network restart
Restarting network (via systemctl):
Socket error Event: 32 Error: 10053.
Connection closing...Socket close.
Connection closed by foreign host.
Disconnected from remote host(root2) at 17:10:54.
Type `help' to learn how to use Xshell prompt.
[c:~]$
9.连接到ip 信息
[root@rac2 ~]# ifconfig -a
enp0s3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.6.20 netmask 255.255.255.0 broadcast 192.168.3.255

lo: flags=73<UP,LOOPBACK,RUNN
10. 启动crs
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/crsctl start crs
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
[root@rac2 ~]#
11. 更新网卡信息（两个节点都需要操作，对于不同网段的ip，如果是同网段的可以忽略）
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/oifcfg getif
enp0s3 192.168.3.0 global public
enp0s8 10.10.10.0 global cluster_interconnect,asm
[root@rac2 ~]#
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/oifcfg setif -global enp0s3/192.168.6.0:public
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/oifcfg getif
enp0s8 10.10.10.0 global cluster_interconnect,asm
enp0s3 192.168.6.0 global public
[root@rac2 ~]#
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/oifcfg delif -global enp0s3
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/oifcfg getif
enp0s8 10.10.10.0 global cluster_interconnect,asm
[root@rac2 ~]#
12. 更新 priv ip （两个节点都需要操作，对于不同网段的ip，如果是同网段的可以忽略）
13. 更新vip （两个节点都需要操作，对于不同网段的ip，如果是同网段的可以忽略）
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl modify nodeapps -n rac2 -A 192.168.6.23/255.255.255.0
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl config vip -n rac2
VIP exists: network number 1, hosting node rac2
VIP Name: rac2-vip
VIP IPv4 Address: 192.168.6.23
VIP IPv6 Address:
VIP is enabled.
VIP is individually enabled on nodes:
VIP is individually disabled on nodes:
[root@rac2 ~]#
14. 更新scan ip
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl config scan
SCAN name: rac-scan, Network: 1
Subnet IPv4: 192.168.6.0/255.255.255.0/, static
Subnet IPv6:
SCAN 1 IPv4 VIP: 192.168.3.184
SCAN VIP is disabled
[root@rac2 ~] /u01/app/19.3.0/grid/bin/srvctl modify scan -n 192.168.6.24
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl config scan
SCAN name: 192.168.6.24, Network: 1
Subnet IPv4: 192.168.6.0/255.255.255.0/, static
Subnet IPv6:
SCAN 1 IPv4 VIP: 192.168.6.24
SCAN VIP is disabled.
15. 启动服务
srvctl enable listener
srvctl enable vip -i " rac2-vip"
srvctl enable vip -i " rac1-vip"
srvctl enable scan_listener
srvctl enable scan
srvctl enable database -d prodb
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl enable listener
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl enable vip -i " rac2-vip"
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl enable scan_listener
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl enable scan
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl start listener
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl start vip -i " rac2-vip"
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl start scan_listener
[root@rac2 ~]# /u01/app/19.3.0/grid/bin/srvctl start scan
[oracle@rac2 ~]$ /u01/app/19.3.0/grid/bin/srvctl start database -d prodb
16. 启动后检查数据库情况
[grid@rac2 ~]$ /u01/app/19.3.0/grid/bin/srvctl status database -d prodb
Instance prodb1 is running on node rac2
[grid@rac2 ~]$
[grid@rac2 ~]$ crsctl stat res -t
