這篇文章給大家分享的是有關(guān)oracle 11gR2RAC如何修改public ip的內(nèi)容。小編覺得挺實用的，因此分享給大家做個參考，一起跟隨小編過來看看吧。
Ⅰ修改public 選擇一個節(jié)點（這里選擇rac1）
查看hosts設(shè)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資源狀態(tài)
[root@rac2 bin]# ./crsctl stat res -t

OCR磁盤組是offline，查下ocr狀態(tài)
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

Device/File not configured
Device/File not configured
Device/File not configured

發(fā)現(xiàn)無效的磁盤組OCR,那么刪掉 (這一步是我之前做實驗替換了ocr的，直接略）
[grid@rac1 ~]$ srvctl remove diskgroup -g OCR
[grid@rac1 ~]$ crsctl stat res -t

查看當(dāng)前public配置
[root@rac1 bin]# ./oifcfg getif
eth2 10.0.0.0 global cluster_interconnect
eth0 192.168.215.0 global public
顯示為215網(wǎng)段，那么要改為56網(wǎng)段
[root@rac1 bin]# ./oifcfg delif -global eth0/192.168.215.0 #刪掉215網(wǎng)段
[root@rac1 bin]# ./oifcfg setif -global eth0/192.168.56.0:public #設(shè)置56網(wǎng)段
[root@rac1 bin]# ./oifcfg getif #查看修改情況兩個節(jié)點都看一下
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
修改兩節(jié)點hosts文件 只改pubic ip 的網(wǎng)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
修改實際public地址為56網(wǎng)段的，兩個節(jié)點都要改。
[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 依然選擇rac1（官方文檔中是停一個節(jié)點修改這個節(jié)點，然后啟動在修改下一個節(jié)點）
停止節(jié)點1的實例和vip資源
[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
修改兩節(jié)點對應(yīng)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
查看結(jié)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
重啟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
自己重啟了？看一下資源狀態(tài)
[root@rac1 bin]# ./crsctl stat res -t

修改兩節(jié)點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 （這次選擇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
#顯示還是215網(wǎng)段
停止scan和listener
[root@rac2 bin]# ./srvctl stop scan_listener
[root@rac2 bin]# ./srvctl stop scan
修改兩節(jié)點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 #修改為56網(wǎng)段
修改scanip
[root@rac2 bin]# ./srvctl modify scan -n scanip #刷新scanip，實際上從hosts中讀取地址
[root@rac2 bin]# ./srvctl config scan #查看刷新情況
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，重啟scan和listener
[root@rac2 bin]# ./srvctl start scan
[root@rac2 bin]# ./srvctl start scan_listener
