Oracle 10g RAC修改IP/VIP地址示例

发布时间：2020-06-18 02:28:16 来源：网络阅读：839 作者：koumm 栏目：关系型数据库

一、准备工作

1. 数据库信息

操作系统版本 : OEL5.4 x64
数据库版本 : Oracle 10.2.0.5 x64 RAC

2. IP地址对应信息

说明: 服务器主机名不能更改，如确实要改名，需要重装CRS解决，还不如重新安装呢。
本文环境是10g rac+ocfs+asm,心跳地址不变，IP地址因环境限制暂时采用同一个网段，不同的IP地址，但是过程与不同网段改名一致。

原IP地址:
192.168.0.6         node1         修改为: 192.168.0.206
192.168.0.7         node2         修改为: 192.168.0.207
192.168.0.8         node1-vip     修改为: 192.168.0.208
192.168.0.9         node2-vip     修改为: 192.168.0.209
10.10.10.10         node1-priv    不变
10.10.10.20         node2-priv    不变

调整后IP地址:
192.168.0.206       node1
192.168.0.207       node2
192.168.0.208       node1-vip
192.168.0.209       node2-vip
10.10.10.10         node1-priv
10.10.10.20         node2-priv

二、停止oracle rac服务。

1. 关闭ORACLE RAC进程, 可在任一节点上执行，这里采用节点1.

[root@node1 ~]# cd /u01/app/oracle/product/10.2.0/crs/bin
[root@node1 ~]# pwd
/u01/app/oracle/product/10.2.0/crs/bin

# 依次关闭数据库, asm, node application, crs

[root@node1 bin]# ./srvctl stop database -d orcl
[root@node1 bin]# ./srvctl stop asm -n node1
[root@node1 bin]# ./srvctl stop asm -n node2
[root@node1 bin]# ./srvctl stop nodeapps -n node1
[root@node1 bin]# ./srvctl stop nodeapps -n node2

# 查看关闭情况

[root@node1 bin]# ./crs_stat -t

Name           Type           Target    State     Host
------------------------------------------------------------
ora....SM1.asm application    OFFLINE   OFFLINE
ora....E1.lsnr application    OFFLINE   OFFLINE
ora.node1.gsd application    OFFLINE   OFFLINE
ora.node1.ons application    OFFLINE   OFFLINE
ora.node1.vip application    OFFLINE   OFFLINE
ora....SM2.asm application    OFFLINE   OFFLINE
ora....E2.lsnr application    OFFLINE   OFFLINE
ora.node2.gsd application    OFFLINE   OFFLINE
ora.node2.ons application    OFFLINE   OFFLINE
ora.node2.vip application    OFFLINE   OFFLINE
ora.orcl.db    application    OFFLINE   OFFLINE
ora....l1.inst application    OFFLINE   OFFLINE
ora....l2.inst application    OFFLINE   OFFLINE

2. 关闭crs后台进程

#注：必须在所有（node1,node2）节点上root用户执行。

[root@node1 bin]# /etc/init.d/init.crs stop

Shutting down Oracle Cluster Ready Services (CRS):
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
Shutdown has begun. The daemons should exit soon.

[root@node2 bin]# /etc/init.d/init.crs stop

Shutting down Oracle Cluster Ready Services (CRS):
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
Shutdown has begun. The daemons should exit soon.

三、修改服务器IP地址

1. node1,node2 修改 /etc/hosts 文件。保持2个节点的一致

[root@node1 bin]# vi /etc/hosts

192.168.0.206         node1
192.168.0.207         node2
192.168.0.208         node1-vip
192.168.0.209         node2-vip
10.10.10.10           node1-priv
10.10.10.20           node2-priv

2. 在两个节点上分别修改eth0地址、网关，心跳地址不变，不改动。

node1节点：
[root@node1 bin]# more /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0C:29:EA:C7:1F
IPADDR=192.168.0.206
NETMASK=255.255.255.0
ONBOOT=yes

node2节点：
[root@node2 bin]# more /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.0.207
NETMASK=255.255.255.0
HWADDR=00:0c:29:6c:08:aa

3. 重启网络服务

# service network restart
# service network restart

四、启动crs.

1. 在两个节点（node1,node2）启动crs, 并关闭随crs启动的服务

[root@node1 bin]# /etc/init.d/init.crs start
Startup will be queued to init within 30 seconds.

[root@node2 bin]# /etc/init.d/init.crs start
Startup will be queued to init within 30 seconds.

#由于IP地址还未修改完成，一些服务器无法启动成功，需要关闭掉。

[root@node1 bin]# ./crs_stat -t
Name           Type           Target    State     Host
------------------------------------------------------------
ora....SM1.asm application    ONLINE    ONLINE    node1
ora....E1.lsnr application    ONLINE    OFFLINE
ora.node1.gsd application    ONLINE    OFFLINE
ora.node1.ons application    ONLINE    ONLINE    node1
ora.node1.vip application    ONLINE    ONLINE    node1
ora....SM2.asm application    ONLINE    ONLINE    node2
ora....E2.lsnr application    ONLINE    OFFLINE
ora.node2.gsd application    ONLINE    OFFLINE
ora.node2.ons application    ONLINE    ONLINE    node2
ora.node2.vip application    ONLINE    ONLINE    node2
ora.orcl.db    application    ONLINE    OFFLINE
ora....l1.inst application    ONLINE    OFFLINE
ora....l2.inst application    ONLINE    OFFLINE

#关闭所有服务

#确认关闭

[root@node1 bin]# ./crs_stat -t
Name           Type           Target    State     Host
------------------------------------------------------------
ora....SM1.asm application    OFFLINE   OFFLINE
ora....E1.lsnr application    OFFLINE   OFFLINE
ora.node1.gsd application    OFFLINE   OFFLINE
ora.node1.ons application    OFFLINE   OFFLINE
ora.node1.vip application    OFFLINE   OFFLINE
ora....SM2.asm application    OFFLINE   OFFLINE
ora....E2.lsnr application    OFFLINE   OFFLINE
ora.node2.gsd application    OFFLINE   OFFLINE
ora.node2.ons application    OFFLINE   OFFLINE
ora.node2.vip application    OFFLINE   OFFLINE
ora.orcl.db    application    OFFLINE   OFFLINE
ora....l1.inst application    OFFLINE   OFFLINE
ora....l2.inst application    OFFLINE   OFFLINE
[root@node1 bin]#

2. 使用oifcfg修改网卡设置, oifconfig可以用来设置和查看网卡使用的方式.

注： node1,node2上操作，如果修改的网段相同，可以不做，但是如果其它网段，可以按如下方式

#查看当前配置

[root@node1 bin]# ./oifcfg getif -global

eth0 192.168.0.0 global public
eth2 10.10.10.0 global cluster_interconnect

#删除当前配置

[root@node1 bin]# ./oifcfg delif -global eth0
[root@node1 bin]# ./oifcfg delif -global eth2
[root@node1 bin]# ./oifcfg getif

#重新添加，内联及心跳网段（对应IP地址子网掩码配置网段）
[root@node1 bin]# ./oifcfg setif -global eth0/192.168.0.0:public
[root@node1 bin]# ./oifcfg setif -global eth2/10.10.10.0:cluster_interconnect

[root@node1 bin]# ./oifcfg getif
eth0 192.168.0.0 global public
eth2 10.10.10.0 global cluster_interconnect

[root@node1 bin]# ./oifcfg iflist

eth0 192.168.0.0
eth2 10.10.10.0

3. node1,node2 修改VIP地址

[root@node1 bin]# ./srvctl modify nodeapps -n node1 -A 192.168.0.208/255.255.255.0/eth0
[root@node1 bin]# ./srvctl modify nodeapps -n node2 -A 192.168.0.209/255.255.255.0/eth0

4. node1,node2 设置listener.ora和tnsnames.ora

#查看原IP地址，修改为现在的IP地址。

[root@node1 bin]# vi /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora

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 = 192.168.0.206)(PORT = 1521)(IP = FIRST))
    )
)

5. node1上操作，启动node 应用, asm, 数据库

[root@node1 bin]# ./srvctl start nodeapps -n node1
[root@node1 bin]# ./srvctl start nodeapps -n node2
[root@node1 bin]# ./srvctl start asm -n node1
[root@node1 bin]# ./srvctl start asm -n node2
[root@node1 bin]# ./srvctl start instance -d orcl -i orcl1
[root@node1 bin]# ./srvctl start instance -d orcl -i orcl2

[root@node1 bin]# ./crs_stat -t
Name           Type           Target    State     Host
------------------------------------------------------------
ora....SM1.asm application    ONLINE    ONLINE    node1
ora....E1.lsnr application    ONLINE    ONLINE    node1
ora.node1.gsd application    ONLINE    ONLINE    node1
ora.node1.ons application    ONLINE    ONLINE    node1
ora.node1.vip application    ONLINE    ONLINE    node1
ora....SM2.asm application    ONLINE    ONLINE    node2
ora....E2.lsnr application    ONLINE    ONLINE    node2
ora.node2.gsd application    ONLINE    ONLINE    node2
ora.node2.ons application    ONLINE    ONLINE    node2
ora.node2.vip application    ONLINE    ONLINE    node2
ora.orcl.db    application    ONLINE    ONLINE    node2
ora....l1.inst application    ONLINE    ONLINE    node1
ora....l2.inst application    ONLINE    ONLINE    node2

若启动出现问题，再进行判断。

6. 确认IP, 修改完成。

[root@node1 bin]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:29:EA:C7:1F
inet addr:192.168.0.206 Bcast:192.168.0.255 Mask:255.255.255.0

eth0:1    Link encap:Ethernet HWaddr 00:0C:29:EA:C7:1F
          inet addr:192.168.0.208 Bcast:192.168.0.255 Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

eth2 Link encap:Ethernet HWaddr 00:0C:29:EA:C7:29
inet addr:10.10.10.10 Bcast:10.10.10.255 Mask:255.255.255.0

[root@node2 ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:29:6C:08:AA
inet addr:192.168.0.207 Bcast:192.168.0.255 Mask:255.255.255.0

eth0:1    Link encap:Ethernet HWaddr 00:0C:29:6C:08:AA
          inet addr:192.168.0.209 Bcast:192.168.0.255 Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

eth2 Link encap:Ethernet HWaddr 00:0C:29:6C:08:B4
inet addr:10.10.10.20 Bcast:10.10.10.255 Mask:255.255.255.0

7. 重启节点测试，rac启动均正常，无问题。
