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
# srvctl disable vip -h
Disable the VIPs from Oracle Clusterware management.
Usage: srvctl disable vip -i[-v]
-i VIP name
-h Print usage
-v Verbose output
# srvctl disable vip -i "node1-vip"
# srvctl disable vip -i "node2-vip"
# srvctl stop vip -h
Stop the specified VIP or VIPs on a node.
Usage: srvctl stop vip { -n | -i} [-f] [-r] [-v]
-n Node name
-i VIP name
-r > -f Force stop
-h Print usage
-v Verbose output
# srvctl stop vip -n node1
# srvctl stop vip -n node2
2）禁用和停止listener
# srvctl disable listener
# srvctl stop listener
3）禁用和停止scan及scan_listener
# srvctl disable scan_listener
# srvctl stop scan_listener
# srvctl disable scan
# srvctl stop scan
#
4）在所有节点停止CRS 服务
# crsctl stop crs

二、在操作系统下修改IP（所有节点）
# 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
192.168.8.11node1
192.168.8.13node1-vip
10.10.10.11node1-priv
192.168.8.12node2
192.168.8.14node2-vip
10.10.10.12 node2-priv
192.168.8.15 rac_scan
# 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
192.168.8.111node1
192.168.8.113node1-vip
10.10.10.11node1-priv
192.168.8.112node2
192.168.8.114node2-vip
10.10.10.12 node2-priv
192.168.8.115 rac_scan
~
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
三、重新启动CRS 服务
# crsctl start crs
CRS-4123: Oracle High Availability Services has been started.
# 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
# crs_stat -t

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| -global} {/:}...
oifcfg getif [-node| -global] [ -if [/] [-type ] ]
oifcfg delif [{-node| -global} [[/]]]
oifcfg [-help]
- name of the host, as known to a communications network
- name by which the interface is configured in the system
- subnet address of the interface
- type of the interface { cluster_interconnect | public }
# oifcfg iflist
eth0192.168.8.0
eth110.10.10.0
# oifcfg iflist -p
eth0192.168.8.0PRIVATE
eth110.10.10.0PRIVATE
# oifcfg iflist -p -n
eth0192.168.8.0PRIVATE255.255.255.0
eth110.10.10.0PRIVATE255.255.255.0
[root@node1 ~]# oifcfg getif -global
eth0192.168.8.0globalpublic
eth110.10.10.0globalcluster_interconnect
删除原来的网卡ip 配置信息
[root@node1 ~]# oifcfg delif
# oifcfg getif
# oifcfg getif -global
重新配置网卡ip信息
[root@node1 ~]# oifcfg setif -global eth0/192.168.8.0:public
# oifcfg getif
eth0192.168.8.0globalpublic
# oifcfg setif -global eth1/10.10.10.0:cluster_interconnect
# oifcfg getif -global
eth0192.168.8.0globalpublic
eth110.10.10.0globalcluster_interconnect
# oifcfg iflist
eth0192.168.8.0
eth110.10.10.0
# oifcfg iflist -p -n
eth0192.168.8.0PRIVATE255.255.255.0
eth110.10.10.0PRIVATE255.255.255.0
查看并重新配置VIP
# srvctl config vip -n node1
VIP exists.:node1
VIP exists.: /node1-vip/192.168.8.113/255.255.255.0/eth0
# srvctl config vip -n node2
VIP exists.:node2
VIP exists.: /node2-vip/192.168.8.114/255.255.255.0/eth0
# clear
# srvctl modify nodeapps -h
Modifies the configuration for a node application.
Usage: srvctl modify nodeapps {[-n-A /]] | [-S /]]} [-m ] [-p ] [-e ] [ -l] [-r] [-t [:][,[:]...]] [-v]
-A Node level Virtual IP address
-S //]NET address spec for network
-m The multicast IP address for eONS
-p The port number for eONS
-e Local listen port for eONS daemon (Default port number is 2016)
-l ONS listening port for local client connections
-r ONS listening port for connections from remote hosts
-t [:][,[:]...]List of remote host/port pairs for ONS daemons outside this cluster
-h Print usage
-v Verbose output
# srvctl modify nodeapps -A 192.168.8.113/255.255.255.0/eth0 -n node1
# srvctl modify nodeapps -A 192.168.8.114/255.255.255.0/eth0 -n node2
# srvctl config vip -n node1
VIP exists.:node1
VIP exists.: /node1-vip/192.168.8.113/255.255.255.0/eth0
# 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:
# 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
# srvctl modify scan -h
Modifies the SCAN name.
Usage: srvctl modify scan -n
-n Domain name qualified SCAN name
-h Print usage
# srvctl modify scan -n rac_scan
# 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
#
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
# srvctl enable listener
# srvctl enable vip -i "node1-vip"
# srvctl enable vip -i "node2-vip"
# srvctl enable scan_listener
# srvctl enable scan
# srvctl enable database -d prod
# srvctl start listener
# srvctl start vip -n node1,node2
[# srvctl start scan_listener
# srvctl start scan
# srvctl start database -d prod
