楼主

环境：

OS:Linux As 5
DB:10.2.0.5

机房搬迁或是网络重新规划的时候,这个时候我们就需要修改节点的ip地址,下面说明如何修改两个节点的ip地址.

1.修改ip规划
public地址修改

192.168.1.106 node1 node1
192.168.1.107 node2 node2

计划修改为

192.168.1.116 node1 node1
192.168.1.117 node2 node2

vip地址修改

192.168.1.116 node1-vip node1-vip
192.168.1.117 node2-vip node2-vip

计划修改为

192.168.1.216 node1-vip node1-vip
192.168.1.217 node2-vip node2-vip

2.修改网卡i地址

[root@node1 network-scripts]# vi ifcfg-eth0
# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:0C:29:1F:C3:06
ONBOOT=yes
TYPE=Ethernet
NETMASK=255.255.255.0
IPADDR=192.168.1.116
GATEWAY=192.168.1.1
USERCTL=no
IPV6INIT=no
PEERDNS=yes
[root@node2 network-scripts]# vi ifcfg-eth0
# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
HWADDR=00:0c:29:d1:b1:2b
NETMASK=255.255.255.0
IPADDR=192.168.1.117
GATEWAY=192.168.1.1
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=no

3.修改hosts文件

[root@node1 /]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
#Public
#Private
#Virtual
192.168.1.116   node1   node1
192.168.1.117   node2   node2
10.10.10.1      node1-priv      node1-priv
10.10.10.2      node2-priv      node2-priv
192.168.1.216   node1-vip       node1-vip
192.168.1.217   node2-vip       node2-vip
[root@node2 /]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
#Public
#Private
#Virtual
192.168.1.116   node1   node1
192.168.1.117   node2   node2
10.10.10.1      node1-priv      node1-priv
10.10.10.2      node2-priv      node2-priv
192.168.1.216   node1-vip       node1-vip
192.168.1.217   node2-vip       node2-vip

4.重启网路
分别在两个节点上重启网路

5.修改两个节点的监听器

node1-> vi listener.ora
# listener.ora.node1 Network Configuration File: /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora.node1
# Generated by Oracle configuration tools.
SID_LIST_LISTENER_NODE1 =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
)
)
LISTENER_NODE1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1-vip)(PORT = 1521)(IP = FIRST))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.116)(PORT = 1521)(IP = FIRST))
)
)
node2-> vi listener.ora
# listener.ora.node2 Network Configuration File: /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora.node2
# Generated by Oracle configuration tools.
SID_LIST_LISTENER_NODE2 =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
)
)
LISTENER_NODE2 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node2-vip)(PORT = 1521)(IP = FIRST))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.117)(PORT = 1521)(IP = FIRST))
)
)

6.修改vip地址
节点1

node1-> oifcfg getif
eth0 192.168.1.0 global public
eth1 10.10.10.0 global cluster_interconnect
node1-> srvctl modify nodeapps -n node1 -A 192.168.1.116/255.255.255.0/eth0
PRKO-2117 : This command should be executed as the system privilege user.
node1-> su - root
Password:
[root@node1 ~]# /u01/app/oracle/product/10.2.0/crs_1/bin/srvctl modify nodeapps -n node1 -A 192.168.1.216/255.255.255.0/eth0

节点2

node2-> oifcfg getif
eth0 192.168.1.0 global public
eth1 10.10.10.0 global cluster_interconnect
[root@node2 ~]# /u01/app/oracle/product/10.2.0/crs_1/bin/srvctl modify nodeapps -n node2 -A 192.168.1.217/255.255.255.0/eth0

7.启动相应的服务
查看是否有没有启动的资源

node1-> crs_stat -t

若是有相关服务没有启动可以使用crs_start启动.
