类别 修改前 修改后
PUBLIC 172.18.4.182 rac1 192.168.56.10 rac1
172.18.4.184 rac2 192.168.56.20 rac2
PRIVATE 10.10.10.10 rac1priv 20.20.20.10 rac1priv
10.10.10.20 rac2priv 20.20.20.20 rac1priv
VIP 172.18.4.186 rac1vip 192.168.56.30 rac1vip
172.18.4.187 rac2vip 192.168.56.40 rac2vip
SCAN 172.18.4. 172 scanip 192.168.56.50 scanip

修改Public Ip

  • 1) 查看当前集群 Ip信息
[grid@rac1 ~]$ su root

Password:

[root@rac1 grid]# oifcfg getif

eth1  10.10.10.0  global  cluster_interconnect

eth0  172.18.4.0  global  public
  • 2) 利用oifcfg命令，进行删除，修改public ip
[grid@rac1 ~]$ oifcfg delif -global eth0/172.18.4.0

[grid@rac1 ~]$ oifcfg setif -global eth0/192.168.56.0:public

[grid@rac1 ~]$ oifcfg getif

eth1  10.10.10.0  global  cluster_interconnect

eth0  192.168.56.0  global  public
  • 3) OS修改/etc/hosts, ifcfg-eth0文件（On all node）
# 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

::1     localhost6.localdomain6 localhost6

# PUBLIC

192.168.56.10  rac1

192.168.56.20  rac2

--------------------------------------------------

# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=none

ONBOOT=yes

HWADDR=08:00:27:2e:0e:4e

IPADDR=192.168.56.10

NETMASK=255.255.255.0

--------------------------------------------------

重启网络服务

# service network restart

修改vip

  • 1) 停止节点1的实例和vip资源
[grid@rac1 ~]$ srvctl stop instance -d orcl -n rac1

[grid@rac1 ~]$ srvctl stop vip -n rac1 -f
  • 2) 查看原始vip资源配置
[grid@rac1 ~]$ srvctl config nodeapps -a

VIP exists.:rac1

VIP exists.: /rac1vip/192.168.56.30/255.255.255.0/eth0

VIP exists.:rac2

VIP exists.: /rac2vip/192.168.56.40/255.255.255.0/eth0
  • 3) 修改/etc/hosts文件中的 vip
#VIP

192.168.56.30 rac1vip

192.168.56.40 rac2vip
  • 4) 使用root用户修改vip资源
[grid@rac1 ~]$ srvctl modify nodeapps -n rac1 -A 192.168.56.30/255.255.255.0/eth0

PRCN-2018 : Current user grid is not a privileged user

[grid@rac1 ~]$ su root

Password:

[root@rac1 grid]# srvctl modify nodeapps -n rac1 -A 192.168.56.30/255.255.255.0/eth0
  • 5) 启动服务
[grid@rac1 ~]$ srvctl start vip -n rac1

[grid@rac1 ~]$ srvctl start listener -n rac1

[grid@rac1 ~]$ srvctl start instance -d orcl -n rac1
  • 6) 集群其他节点请重复以上1-5的动作

修改SCAN IP

  • 1) 以grid用户停止资源
[grid@rac1 ~]$ srvctl stop scan_listener

[grid@rac1 ~]$ srvctl stop scan
  • 2) 修改/etc/hosts文件中的SCAN IP
#SCAN IP

192.168.56.50 scanip
  • 3) 以root用户更改SCAN IP
[grid@rac1 ~]$ su root

Password:

[root@rac1 grid]# srvctl modify scan -n scanip
  • 4) 以grid用户更改及启动资源
[grid@rac1 ~]$ srvctl modify scan_listener -u

[grid@rac1 ~]$ srvctl start scan_listener
  • 5) 确认更改
[grid@rac1 ~]$ srvctl config scan

SCAN name: scanip, Network: 1/192.168.56.0/255.255.255.0/eth0

SCAN VIP name: scan1, IP: /scanip/192.168.56.50

[grid@rac1 ~]$ srvctl config scan_listener

SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521

修改Private IP

'在对集群中所有节点操作之前，请先备份 profile.xml 配置文件。作为 grid 用户执行'：

[grid@rac1 ~]$ cd /u01/11.2.0/grid/gpnp/rac1/profiles/peer/

[grid@rac1 peer]$ cp -p profile.xml profile.xml.bak
  • 1) 确保集群中所有节点都已经启动并正常运行
  • 2) 使用grid用户，获取以下信息，例如：
[grid@rac1 peer]$ oifcfg getif

eth1  10.10.10.0  global  cluster_interconnect

eth0  192.168.56.0  global  public
  • 3) 加入新的private ip
[grid@rac1 peer]$ oifcfg setif -global eth1/20.20.20.0:cluster_interconnect

[grid@rac1 peer]$ oifcfg getif

eth1  10.10.10.0  global  cluster_interconnect

eth0  192.168.56.0  global  public

eth1  20.20.20.0  global  cluster_interconnect
  • 4) 使用root用户关闭集群中所有节点并禁用集群（每个节点）
[grid@rac1 peer]$ su root

Password:

[root@rac1 peer]# crsctl stop crs

CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'rac1'

CRS-2673: Attempting to stop 'ora.crsd' on 'rac1'

CRS-2790: Starting shutdown of Cluster Ready Services-managed resources on 'rac1'

CRS-2673: Attempting to stop 'ora.CRSDG.dg' on 'rac1'

CRS-2677: Stop of 'ora.LISTENER_SCAN1.lsnr' on 'rac1' succeeded

CRS-2673: Attempting to stop 'ora.scan1.vip' on 'rac1'

CRS-2677: Stop of 'ora.LISTENER.lsnr' on 'rac1' succeeded

…

CRS-4133: Oracle High Availability Services has been stopped.

[root@rac1 peer]# crsctl disable crs

CRS-4621: Oracle High Availability Services autostart is disabled.
  • 5) 更改/etc/hosts,ifcfg-eth1文件（两个节点）
# vi /etc/hosts

# PRIVATE

20.20.20.10  rac1priv

20.20.20.20  rac2priv

# vi /etc/sysconfig/network-scripts/ifcfg-eth1

# Intel Corporation 82540EM Gigabit Ethernet Controller

DEVICE=eth1

BOOTPROTO=none

ONBOOT=yes

HWADDR=08:00:27:b1:33:73

IPADDR=20.20.20.10

NETMASK=255.255.255.0

重启网络服务

# service network restart

确保能相互ping 通

[root@rac1 ~]# ping rac1priv

[root@rac1 ~]# ping rac2priv
  • 6) 使用root用户激活集群并重新启动集群中所有节点（每个节点）
[grid@rac1 ~]$ su root

Password:

[root@rac1 grid]# crsctl enable crs

CRS-4622: Oracle High Availability Services autostart is enabled.

[root@rac1 grid]# crsctl start crs

CRS-4123: Oracle High Availability Services has been started.
  • 7) 删除旧的private ip
[grid@rac2 ~]$ oifcfg delif -global eth1/10.10.10.0

[grid@rac2 ~]$ oifcfg getif

eth0  192.168.56.0  global  public

eth1  20.20.20.0  global  cluster_interconnect
