如何修改11gR2 RAC PRIVATE IP

           在一套数据库系统搭建之前,本应该认真规划存储、网络、主机名等基本配置信息的,一旦确定下来,就不要轻易去改诸如hostname、IP地址等配置信息。除非不得已或规划有问题的前提下,我们需要不得已而为之。这不,自己就犯下了这个错误:之前在OEL 5.5 X86_64位系统上搭建了一套11gR2 的双节点RAC做测试用,用完之后,就连两台服务器都shutdown。后来,又搭建了一套新的OEL 5.5 X86_64+11gR2 RAC的开发系统,由于自己的疏忽,这套开发用的RAC机器的私有IP(private IP)同原来的那套测试RAC私有IP地址冲突,现在想用原来的那套RAC问题就来了,根本就无法使用,因为测试RAC根本启不来!!!自己搬石头砸自己脚啊,不过呢,好在自己给这套开发的RAC系统搭建了一套物理dataguard,于是乎,先将开发RAC系统作一个switchover先切换至物理备库,然后停开发RAC系统,启动测试RAC系统,修改测试RAC系统的私有IP,这样,改完Private IP之后,两套RAC就都可以正常使用了。绕弯了,呵呵,谁让自己前期没有规划好了,算是给自己一个教训。

           本文就简单记录一下在OEL 5.5 X86_64+11gR2 RAC系统下如何修改私有IP?

          1 修改Private IP前,服务器IP配置信息:

Source IP Configuration
hostname  type    IP Address Domain Name Interface
rac1 public IP 172.16.0.191 rac1.localdomain  eth0
rac1 private IP 192.168.93.1 rac1-priv.localdomain eth1
rac1 virtual IP 172.16.0.193 rac1-vip.localdomain eth0:1
rac2 public IP 172.16.0.192 rac2.localdomain eth0
rac2 private IP 192.168.93.2 rac2-priv.localdomain eth1
rac2 virtual IP 172.16.0.194 rac2-vip.localdomain eth0:1
SCAN SCAN IP 172.16.0.203 rac-scan.localdomain rac-scan

 

              欲将Private IP修改为下述目标配置:

 

Target IP configuration
hostname  type    IP Address Domain Name Interface
rac1 public IP 172.16.0.191 rac1.localdomain  eth0
rac1 private IP 192.168.94.1 rac1-priv.localdomain eth1
rac1 virtual IP 172.16.0.193 rac1-vip.localdomain eth0:1
rac2 public IP 172.16.0.192 rac2.localdomain eth0
rac2 private IP 192.168.94.2 rac2-priv.localdomain eth1
rac2 virtual IP 172.16.0.194 rac2-vip.localdomain eth0:1
SCAN SCAN IP 172.16.0.203 rac-scan.localdomain rac-scan

 

          2 修改Private IP前,节点1服务器/etc/hosts配置文件内容:

[root@rac1 ~]# uname -rm
2.6.18-194.el5xen x86_64
[root@rac1 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
#127.0.0.1              localhost.localdomain localhost
127.0.0.1               localhost
::1             localhost6.localdomain6 localhost6
#172.16.0.191           rac1.localdomain rac1

172.16.0.191            rac1.localdomain        rac1
172.16.0.193            rac1-vip.localdomain    rac1-vip
192.168.93.1            rac1-priv.localdomain   rac1-priv

172.16.0.192            rac2.localdomain        rac2
172.16.0.194            rac2-vip.localdomain    rac2-vip
192.168.93.2            rac2-priv.localdomain   rac2-priv

172.16.0.203            rac-scan.localdomain    rac-scan
[root@rac1 ~]#

          3 修改Private IP前,服务器RAC集群服务信息:

[root@rac1 ~]# su - grid
rac1-> crs_stat -t

rac1-> 

          4 用oifcfg开始修改Private IP:

             修改Private IP之前,grid用户用olsnodes确认节点状态

rac1-> olsnodes -n -s   
rac1    1       Active
rac2    2       Active
rac1-> oifcfg getif
eth0  172.16.0.0  global  public
eth1  192.168.93.0  global  cluster_interconnect
rac1-> 

             修改Private IP,grid用户用oifcfg命令修改,修改之后,并删掉之前的那条配置信息

rac1-> oifcfg setif -global eth1/192.168.94.0:cluster_interconnect
rac1-> oifcfg getif
eth0  172.16.0.0  global  public
eth1  192.168.93.0  global  cluster_interconnect
eth1  192.168.94.0  global  cluster_interconnect
rac1-> oifcfg delif -global eth1/192.168.93.0                     
rac1-> oifcfg getif
eth0  172.16.0.0  global  public
eth1  192.168.94.0  global  cluster_interconnect
rac1-> 

             修改Private IP之后,记得确认:

rac1-> oifcfg getif
eth0  172.16.0.0  global  public
eth1  192.168.94.0  global  cluster_interconnect
rac1-> 

          5 关闭数据库、集群服务:

rac1-> srvctl stop database -d devdb

         

          root用户停集群服务:

[root@rac1 ~]# 

          6 修改双节点/etc/hosts配置文件

[root@rac1 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
#127.0.0.1              localhost.localdomain localhost
127.0.0.1               localhost
::1             localhost6.localdomain6 localhost6

172.16.0.191            rac1.localdomain        rac1
172.16.0.193            rac1-vip.localdomain    rac1-vip
192.168.94.1            rac1-priv.localdomain   rac1-priv

172.16.0.192            rac2.localdomain        rac2
172.16.0.194            rac2-vip.localdomain    rac2-vip
192.168.94.2            rac2-priv.localdomain   rac2-priv

172.16.0.203            rac-scan.localdomain    rac-scan
[root@rac1 ~]# 

          7 修改双节点Private IP:

             记得一定要修改双节点/etc/sysconfig/network-scripts/ifcfg-eth1配置文件,因为,不修改的话,下次重启服务器后,Private IP又变成了旧的Private IP,因为ifconfig 配置的IP地址只是临时生效,这步骤切记!

[root@rac1 ~]# ifconfig eth1 192.168.94.1 netmask 255.255.255.0

             修改节点1 /etc/sysconfig/network-scripts/ifcfg-eth1:

[root@rac1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1 
# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)
DEVICE=eth1
BOOTPROTO=none
BROADCAST=192.168.93.255
HWADDR=00:0C:29:E8:15:5E
IPADDR=192.168.93.1
NETMASK=255.255.255.0
NETWORK=192.168.93.0
ONBOOT=yes
TYPE=Ethernet
[root@rac1 ~]# 

             修改节点1 /etc/sysconfig/network-scripts/ifcfg-eth1:

[root@rac1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1 
# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)
DEVICE=eth1
BOOTPROTO=none
BROADCAST=192.168.94.255
HWADDR=00:0C:29:E8:15:5E
IPADDR=192.168.94.1
NETMASK=255.255.255.0
NETWORK=192.168.94.0
ONBOOT=yes
TYPE=Ethernet
[root@rac1 ~]# 

             节点2如法炮制,不再赘述。

         8 启动集群服务,启动数据库。至此,完成在OEL 5.5 X86_64+11gR2 RAC系统下修改私有IP。
