Oracle 11g RAC 修改IP

Oracle 11g RAC 修改IP

     在RAC环境下修改ip地址,会造成数据库停机,所以在搭建、配置RAC前,必须做好ip规划,而主机名是不允许修改的,如果修改必须重新安装CRS.


系统环境:

操作系统:RedHat EL5.5

集群软件: GI 11G

数据库软件:Oracle 11.2.0.1


修改ip 方法:


一、禁用和停止相关的resource

1)禁用和停止 vip service

[root@node1 ~]# srvctl disable vip -h

Disable the VIPs from Oracle Clusterware management.

Usage: srvctl disable vip -i <vip_name> [-v]
   -i <vip_name>            VIP name
   -h                       Print usage
   -v                       Verbose output

[root@node1 ~]# srvctl disable vip -i "node1-vip"
[root@node1 ~]# srvctl disable vip -i "node2-vip"


[root@node1 ~]# srvctl stop vip -h

Stop the specified VIP or VIPs on a node.

Usage: srvctl stop vip { -n <node_name>  | -i <vip_name> } [-f] [-r] [-v]
   -n <node_name>           Node name
   -i <vip_name>            VIP name
   -r                       Relocate VIP
   -f                       Force stop
   -h                       Print usage
   -v                       Verbose output
[root@node1 ~]# srvctl stop vip -n node1
[root@node1 ~]# srvctl stop vip -n node2


2)禁用和停止listener

[root@node1 ~]# srvctl disable listener
[root@node1 ~]# srvctl stop listener

3)禁用和停止scan及scan_listener
[root@node1 ~]# srvctl disable scan_listener
[root@node1 ~]# srvctl stop scan_listener
[root@node1 ~]# srvctl disable scan
[root@node1 ~]# srvctl stop scan

[root@node1 ~]#

4)在所有节点停止CRS 服务
[root@node1 ~]# crsctl stop crs

二、在操作系统下修改IP(所有节点)


[root@node1 ~]# cat /etc/hosts(原ip 信息)


# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1                localhost
192.168.8.11  node1
192.168.8.13  node1-vip
10.10.10.11  node1-priv

192.168.8.12  node2
192.168.8.14  node2-vip
10.10.10.12   node2-priv

192.168.8.15   rac_scan

[root@node1 ~]# vi /etc/hosts(修改后ip 信息)

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1                localhost
192.168.8.111  node1
192.168.8.113  node1-vip
10.10.10.11  node1-priv

192.168.8.112  node2
192.168.8.114  node2-vip
10.10.10.12   node2-priv

192.168.8.115   rac_scan
~

[root@node1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0


三、重新启动CRS 服务

[root@node1 ~]# crsctl start crs
CRS-4123: Oracle High Availability Services has been started.


[root@node1 ~]# crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online


被禁用服务未启动
[root@node1 ~]# crs_stat -t

rac_web        application    ONLINE    ONLINE    node1       
web_vip        application    ONLINE    ONLINE    node1       

四、通过oifcfg 工具修改ip

[root@node1 ~]# oifcfg

Name:
       oifcfg - Oracle Interface Configuration Tool.

Usage:  oifcfg iflist [-p [-n]]
       oifcfg setif {-node <nodename> | -global} {<if_name>/<subnet>:<if_type>}...
       oifcfg getif [-node <nodename> | -global] [ -if <if_name>[/<subnet>] [-type <if_type>] ]
       oifcfg delif [{-node <nodename> | -global} [<if_name>[/<subnet>]]]
       oifcfg [-help]

       <nodename> - name of the host, as known to a communications network
       <if_name>  - name by which the interface is configured in the system
       <subnet>   - subnet address of the interface
       <if_type>  - type of the interface { cluster_interconnect | public }

[root@node1 ~]# oifcfg iflist
eth0  192.168.8.0
eth1  10.10.10.0
[root@node1 ~]# oifcfg iflist -p
eth0  192.168.8.0  PRIVATE
eth1  10.10.10.0  PRIVATE
[root@node1 ~]# oifcfg iflist -p -n
eth0  192.168.8.0  PRIVATE  255.255.255.0
eth1  10.10.10.0  PRIVATE  255.255.255.0
[root@node1 ~]# oifcfg getif -global
eth0  192.168.8.0  global  public
eth1  10.10.10.0  global  cluster_interconnect

删除原来的网卡ip 配置信息

[root@node1 ~]# oifcfg delif 
[root@node1 ~]# oifcfg getif
[root@node1 ~]# oifcfg getif -global


重新配置网卡ip信息

[root@node1 ~]# oifcfg setif -global eth0/192.168.8.0:public
[root@node1 ~]# oifcfg getif
eth0  192.168.8.0  global  public
[root@node1 ~]# oifcfg setif -global eth1/10.10.10.0:cluster_interconnect
[root@node1 ~]# oifcfg getif -global
eth0  192.168.8.0  global  public
eth1  10.10.10.0  global  cluster_interconnect
[root@node1 ~]# oifcfg iflist
eth0  192.168.8.0
eth1  10.10.10.0
[root@node1 ~]# oifcfg iflist -p -n
eth0  192.168.8.0  PRIVATE  255.255.255.0
eth1  10.10.10.0  PRIVATE  255.255.255.0
查看并重新配置VIP

[root@node1 ~]# srvctl config vip -n node1
VIP exists.:node1
VIP exists.: /node1-vip/192.168.8.113/255.255.255.0/eth0
[root@node1 ~]# srvctl config vip -n node2
VIP exists.:node2
VIP exists.: /node2-vip/192.168.8.114/255.255.255.0/eth0
[root@node1 ~]# clear

[root@node1 ~]# srvctl modify nodeapps -h

Modifies the configuration for a node application.

Usage: srvctl modify nodeapps {[-n <node_name> -A <new_vip_address>/<netmask>[/if1[|if2|...]]] | [-S <subnet>/<netmask>[/if1[|if2|...]]]} [-m <multicast-ip-address>] [-p <multicast-portnum>] [-e <eons-listen-port>] [ -l <ons-local-port> ] [-r <ons-remote-port> ] [-t <host>[:<port>][,<host>[:<port>]...]] [-v]
   -A <addr_str>            Node level Virtual IP address
   -S <subnet>/<netmask>/[if1[|if2...]]  NET address spec for network
   -m <multicast-ip-address>   The multicast IP address for eONS
   -p <multicast-portnum>    The port number for eONS
   -e <eons-listen-port>     Local listen port for eONS daemon (Default port number is 2016)
   -l <ons-local-port>      ONS listening port for local client connections
   -r <ons-remote-port>     ONS listening port for connections from remote hosts
   -t <host>[:<port>][,<host>[:<port>]...]  List of remote host/port pairs for ONS daemons outside this cluster
   -h                       Print usage
   -v                       Verbose output


[root@node1 ~]# srvctl modify nodeapps -A 192.168.8.113/255.255.255.0/eth0 -n node1
[root@node1 ~]# srvctl modify nodeapps -A 192.168.8.114/255.255.255.0/eth0 -n node2
[root@node1 ~]# srvctl config vip -n node1
VIP exists.:node1
VIP exists.: /node1-vip/192.168.8.113/255.255.255.0/eth0
[root@node1 ~]# srvctl config vip -n node2
VIP exists.:node2
VIP exists.: /node2-vip/192.168.8.114/255.255.255.0/eth0

查看并重新配置SCAN:

[root@node1 ~]# srvctl config scan
SCAN name: rac_scan, Network: 1/192.168.8.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /192.168.8.15/192.168.8.15
[root@node1 ~]# srvctl modify scan -h

Modifies the SCAN name.

Usage: srvctl modify scan -n <scan_name>
   -n <scan_name>           Domain name qualified SCAN name
   -h                       Print usage
[root@node1 ~]# srvctl modify scan -n rac_scan
[root@node1 ~]# srvctl config scan
SCAN name: rac_scan, Network: 1/192.168.8.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /rac_scan/192.168.8.115
[root@node1 ~]#

如果需要修改private ip ,同样可用oifcfg 配置eth1网卡即可!

五、配置完成,启动相关的服务和resource

启动VIP、监听、scan和scan_listener、数据库
[root@node1 ~]# srvctl enable listener      
[root@node1 ~]# srvctl enable vip -i "node1-vip"
[root@node1 ~]# srvctl enable vip -i "node2-vip"
[root@node1 ~]# srvctl enable scan_listener
[root@node1 ~]# srvctl enable scan
[root@node1 ~]# srvctl enable database -d prod
[root@node1 ~]# srvctl start listener      
[root@node1 ~]# srvctl start vip -n node1,node2
     [
[root@node1 ~]# srvctl start scan_listener
[root@node1 ~]# srvctl start scan
[root@node1 ~]# srvctl start database -d prod
