更改VIP 地址

1. 確定用於支援VIP 的介面：

#ifconfig -a

[root@jyrac2 ~]# ifconfig -a

[root@jyrac2 ~]#

2. 停止依賴VIP 的所有資源：

$ srvctl stop instance -d DB -i DB1

$ srvctl stop asm -n node1

$ srvctl stop nodeapps -n node1

[oracle@jyrac2 crs]$ cd /u01/app/oracle/product/10.2.0/crs/bin

[oracle@jyrac2 bin]$ ./srvctl stop instance -d jyrac -i jyrac2

[oracle@jyrac2 bin]$ ./srvctl stop asm -n jyrac2

[oracle@jyrac2 bin]$ ./srvctl stop nodeapps -n jyrac2

3. 驗證VIP 不再處於執行狀態：

$ ifconfig -a [ + $ crs_stat

[root@jyrac2 ~]# ifconfig -a

[oracle@jyrac1 bin]$

從上面的輸出可以看出例項jyrac2已經停止執行節點jyrac2的vip已經停止了

4. 更改/etc/hosts 中的IP 和DNS。

對所有節點進行修改將jyrac2節點的vip從192.168.1.206修改為192.168.1.216

[root@jyrac2 ~]# vi /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 jyrac2 localhost.localdomain localhost

192.168.1.201 jyrac1

192.168.1.204 jyrac2

192.168.1.202 jyrac1-priv

192.168.1.205 jyrac2-priv

192.168.1.203 jyrac1-vip

192.168.1.216 jyrac2-vip

[root@jyrac1 ~]# vi /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 jyrac1 localhost.localdomain localhost

192.168.1.201 jyrac1

192.168.1.204 jyrac2

192.168.1.202 jyrac1-priv

192.168.1.205 jyrac2-priv

192.168.1.203 jyrac1-vip

192.168.1.216 jyrac2-vip

5. 使用srvctl 修改VIP 地址：

修改nodeapps 並提供新的虛擬IP 地址。使用帶有–A 選項的srvctl modify

nodeapps 命令。應以root 使用者身份執行此命令。在本幻燈片的示例中，依次指定

了新IP 地址(192.168.1.216)、相應的網路掩碼(255.255.255.0) 以及希望VIP

使用的介面(eth0)。

[root@jyrac2 ~]# cd /u01/app/oracle/product/10.2.0/crs/bin

[root@jyrac2 bin]# ./srvctl modify nodeapps -n jyrac2 -A 192.168.1.216/255.255.255.0/eth0

[root@jyrac2 bin]#

6. 啟動nodeapps 及依賴它的所有資源：

# srvctl start nodeapps -n node1

[oracle@jyrac2 bin]$ ./srvctl start nodeapps -n jyrac2

[oracle@jyrac2 bin]$ ./srvctl start asm -n jyrac2

[oracle@jyrac2 bin]$ ./srvctl start instance -d jyrac -i jyrac2

7. 對叢集中的所有節點重複上述步驟。由於srvctl 是叢集範圍的管理工具，因此可以

與第一個節點保持連線。

注：如果只更改了IP 地址，並且listener.ora、tnsnames.ora 和初始化引數檔案使

用的是虛擬主機名，則無需對這些檔案進行更改。如果同時更改了節點的虛擬主機名和

VIP 地址，則需要用新的虛擬主機名修改這些檔案。對於listener.ora 檔案，可以使

用netca 來刪除舊監聽程式並建立一個新監聽程式。此外，還需要對連線到舊虛擬主機名

的所有客戶機的tnsnames.ora 檔案進行更改。
