Ⅰ修改public 选择一个节点(这里选择rac1)
查看hosts设置
[root@rac2 bin]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
#public
192.168.215.188 rac1
192.168.215.189 rac2
#private
10.0.0.118 rac1-priv
10.0.0.119 rac2-priv
#vip
192.168.215.120 rac1-vip
192.168.215.121 rac2-vip
#scan
192.168.215.122 scanip
查看crs资源状态
[root@rac2 bin]# ./crsctl stat res -t

OCR磁盘组是offline,查下ocr状态
grid@rac1 ~]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 3388

Device/File integrity check succeeded

发现无效的磁盘组OCR,那么删掉 (这一步是我之前做实验替换了ocr的,直接略)
[grid@rac1 ~]$ srvctl remove diskgroup -g OCR
[grid@rac1 ~]$ crsctl stat res -t

查看当前public配置
[root@rac1 bin]# ./oifcfg getif
eth2 10.0.0.0 global cluster_interconnect
eth0 192.168.215.0 global public
显示为215网段,那么要改为56网段
[root@rac1 bin]# ./oifcfg delif -global eth0/192.168.215.0 #删掉215网段
[root@rac1 bin]# ./oifcfg setif -global eth0/192.168.56.0:public #设置56网段
[root@rac1 bin]# ./oifcfg getif #查看修改情况两个节点都看一下
eth2 10.0.0.0 global cluster_interconnect
eth0 192.168.56.0 global public
[root@rac2 bin]# ./oifcfg getif
eth2 10.0.0.0 global cluster_interconnect
eth0 192.168.56.0 global public
修改两节点hosts文件 只改pubic ip 的网段
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
#public
192.168.56.188 rac1
192.168.56.189 rac2
#private
10.0.0.118 rac1-priv
10.0.0.119 rac2-priv
#vip
192.168.215.120 rac1-vip
192.168.215.121 rac2-vip
#scan
192.168.215.122 scanip
修改实际public地址为56网段的,两个节点都要改。
[root@rac1 bin]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=08:00:27:9c:25:21
TYPE=Ethernet
UUID=c2ec39dd-92bf-41fc-8d41-21d78536c9f9
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.56.189
NETMASK=255.255.255.0
GATEWAY=192.168.56.1
IPV6INIT=no
USERCTL=no
修改完后service network restart
Ⅱ修改vip 依然选择rac1(官方文档中是停一个节点修改这个节点,然后启动在修改下一个节点)
停止节点1的实例和vip资源
[root@rac1 bin]# ./srvctl stop instance -d orcl -n rac1
[root@rac1 bin]# ./srvctl stop vip -n rac1 -f
PRCC-1017 : 192.168.215.190 was already stopped on rac1
PRCR-1005 : Resource ora.rac1.vip is already stopped
修改两节点对应的vip
[root@rac1 bin]# ./srvctl modify nodeapps -n rac1 -A 192.168.56.120/255.255.255.0/eth0
[root@rac1 bin]# ./srvctl modify nodeapps -n rac2 -A 192.168.56.121/255.255.255.0/eth0
查看结果
[root@rac1 bin]# ./srvctl config nodeapps -a
Network exists: 1/192.168.56.0/255.255.255.0/eth0, type static
VIP exists: /192.168.56.120/192.168.56.120/192.168.56.0/255.255.255.0/eth0, hosting node rac1
VIP exists: /192.168.56.121/192.168.56.121/192.168.56.0/255.255.255.0/eth0, hosting node rac2
重启vip和instance
[root@rac1 bin]# ./srvctl start vip -n rac1
PRKO-2420 : VIP is already started on node(s): rac1
[root@rac1 bin]# ./srvctl start listener -n rac1
PRCC-1015 : LISTENER was already running on rac1
PRCR-1004 : Resource ora.LISTENER.lsnr is already running
[root@rac1 bin]# ./srvctl start instance -d orcl -n rac1
PRCC-1015 : orcl was already running on rac1
PRCR-1004 : Resource ora.orcl.db is already running
自己重启了?看一下资源状态
[root@rac1 bin]# ./crsctl stat res -t

修改两节点hosts文件
[root@rac1 bin]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
#public
192.168.56.188 rac1
192.168.56.189 rac2
#private
10.0.0.118 rac1-priv
10.0.0.119 rac2-priv
#vip
192.168.56.120 rac1-vip
192.168.56.121 rac2-vip
#scan
192.168.215.122 scanip
~
Ⅲ修改scanip (这次选择rac2)
我的scanip 名字就叫scanip
[root@rac2 bin]# ./srvctl config scan
SCAN name: scanip, Network: 1/192.168.56.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /scanip/192.168.215.122
#显示还是215网段
停止scan和listener
[root@rac2 bin]# ./srvctl stop scan_listener
[root@rac2 bin]# ./srvctl stop scan
修改两节点hosts文件
[root@rac2 bin]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
#public
192.168.56.188 rac1
192.168.56.189 rac2
#private
10.0.0.118 rac1-priv
10.0.0.119 rac2-priv
#vip
192.168.56.120 rac1-vip
192.168.56.121 rac2-vip
#scan
192.168.56.122 scanip #修改为56网段
修改scanip
[root@rac2 bin]# ./srvctl modify scan -n scanip #刷新scanip,实际上从hosts中读取地址
[root@rac2 bin]# ./srvctl config scan #查看刷新情况
SCAN name: scanip, Network: 1/192.168.56.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /scanip/192.168.56.122
修改成功,重启scan和listener
[root@rac2 bin]# ./srvctl start scan
[root@rac2 bin]# ./srvctl start scan_listener
