Oracle RAC修改public, VIP, SCAN IP

1. grid停止資料庫，停止叢集
srvctl stop database -d orcl -o immediate
srvctl stop listener

2. root停止CRS, 幾個節點都應執行
crsctl stop crsctl

3. 修改/etc/hosts檔案(原檔案應進行備份)
4. 修改public網路卡的IP
/etc/sysconfig/network-scripts/ifcfg-eth0

5. 啟動CRS
[root@dbhost01 ~]# crsctl start crs
[root@dbhost02 ~]# crsctl start crs

6. 修改public ip地址
--檢視當前設定
[root@dbhost01 ~]# oifcfg getif
eth1 10.0.0.0 global cluster_interconnect
eth0 192.168.2.0 global public

oifcfg delif -global eth0
oifcfg setif -global eth0/192.168.31.0:public

[root@dbhost01 ~]# oifcfg delif -global eth0
[root@dbhost01 ~]# oifcfg setif -global eth0/192.168.31.0:public

檢視修改後的設定：
[root@dbhost01 ~]# oifcfg getif
eth1 10.0.0.0 global cluster_interconnect
eth0 192.168.31.0 global public

7. 修改VIP
需要停止資料庫、監聽和VIP，如果按照之前操作，目前資料庫和監聽已經是停止狀態。
[root@dbhost01 ~]# srvctl stop vip -n dbhost01
PRCC-1017 : 192.168.2.22 was already stopped on dbhost01
PRCR-1005 : Resource ora.dbhost01.vip is already stopped
[root@dbhost01 ~]# srvctl stop vip -n dbhost02

[root@dbhost01 ~]# srvctl modify nodeapps -n dbhost01 -A 192.168.31.22/255.255.255.0/eth0
[root@dbhost01 ~]# srvctl modify nodeapps -n dbhost02 -A 192.168.31.23/255.255.255.0/eth0

再次驗證VIP修改完成：
[grid@dbhost01 ~]$ srvctl config vip -n dbhost02
VIP exists: /192.168.31.23/192.168.31.23/192.168.31.0/255.255.255.0/eth0, hosting node dbhost02
[grid@dbhost01 ~]$ srvctl config vip -n dbhost01
VIP exists: /192.168.31.22/192.168.31.22/192.168.31.0/255.255.255.0/eth0, hosting node dbhost01

啟動VIP:
[grid@dbhost01 ~]$ srvctl start vip -n dbhost01
PRKO-2420 : VIP is already started on node(s): dbhost01
[grid@dbhost01 ~]$ srvctl start vip -n dbhost02
[grid@dbhost01 ~]$
[grid@dbhost01 ~]$
[grid@dbhost01 ~]$ ifconfig
eth0 Link encap:Ethernet HWaddr 08:00:27:30:2D:6D

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1


啟動監聽，資料庫
[grid@dbhost01 ~]$ srvctl start listener
[grid@dbhost01 ~]$ srvctl start database -d orcl


8. 修改SCAN IP
檢視scan IP設定:
[grid@dbhost02 ~]$ srvctl config scan
SCAN name: 192.168.2.24, Network: 1/192.168.31.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /192.168.2.24/192.168.2.24

停止scan listener
[grid@dbhost02 ~]$ srvctl stop scan_listener
[grid@dbhost02 ~]$ srvctl stop scan
[grid@dbhost02 ~]$ srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is not running
[grid@dbhost02 ~]$ srvctl stop scan
PRCC-1016 : scan1 was already stopped
PRCR-1005 : Resource ora.scan1.vip is already stopped

[grid@dbhost02 ~]$ srvctl status scan
SCAN VIP scan1 is enabled
SCAN VIP scan1 is not running

使用root使用者修改scan IP:
[root@dbhost02 ~]# srvctl modify scan -n orcl-cluster-scan
[root@dbhost02 ~]# srvctl modify scan_listener -u
[root@dbhost02 ~]# srvctl start scan_listener
[root@dbhost02 ~]# srvctl config scan
SCAN name: orcl-cluster-scan, Network: 1/192.168.31.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /orcl-cluster-scan/192.168.31.24

確認叢集所有資源正常：
[root@dbhost02 ~]# crsctl stat res -t
