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

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
