Oracle RAC更换IP地址

机使用的ip地址给改改. 主机名及修改前后的ip地址如下:

主机名 修改前的ip地址 修改后的ip地址 作用

rac1 192.168.0.181 192.168.1.181 rac1 eth0 native ip

rac2 192.168.0.182 192.168.1.182 rac2 eth0 native ip

rac1-vip 192.168.0.191 192.168.1.191 rac1 vip

rac2-vip 192.168.0.192 192.168.1.192 rac2 vip

rac1-priv 10.10.10.181 10.1.0.181 rac1 eth1 ip interconn

rac2-priv 10.10.10.182 10.1.0.182 rac2 eth1 ip interconn

思路如下, 停止所有oracle相关的进程, 然后修改操作系统的ip设置, 修改与oracle相关的ip地址的设定, 启动crs及相关服务.

具体操作步骤如下:

1 停止oracle相关的所有进程, 包括数据库, asm, node application, crs本身.

1.1 查看当前系统上crs运行的状态

oracle@rac2:/u01/app/oracle/product/10.2.0/crs/bin$ ./crs_stat

1.2 关闭数据库

oracle@rac2:/u01/app/oracle/product/10.2.0/crs/bin$ srvctl stop database -d orcl

1.3 关闭asm实例

oracle@rac2:/u01/app/oracle/product/10.2.0/crs/bin$ srvctl stop asm -n rac1

oracle@rac2:/u01/app/oracle/product/10.2.0/crs/bin$ srvctl stop asm -n rac2

1.4 关闭其他应用程序

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./srvctl stop nodeapps -n rac1

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./srvctl stop nodeapps -n rac2

1.5 关闭crs后台进程, 这一操作会在操作系统一级中止运行的crs后台进程, 必须在所有节点上运行.

rac1:/u01/app/oracle/product/10.2.0/crs/bin# /etc/init.d/ 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.

2 修改操作系统的ip设置

debian的网络配置文件为/etc/network/interfaces和/etc/hosts, 其他linux发行版及unix网络配置文件位置可能并不一样. 以节点rac1为例, 修改前/etc/network/interfaces文件内容为:

# This file describes the network interfaces available on your system

# and how to activate them. For more information, see interfaces(5).

# The loopback network interface

auto lo

iface lo inet loopback

# The primary network interface

auto eth0 eth1

iface eth0 inet static

address 192.168.0.181

netmask 255.255.255.0

network 192.168.0.0

broadcast 192.168.0.255

gateway 192.168.0.1

# dns-* options are implemented by the resolvconf package, if installed

dns-nameservers 202.106.0.20

iface eth1 inet static

address 10.10.10.181

netmask 255.255.255.0

network 10.10.10.0

broadcast 10.10.10.255

修改后内容为:

# This file describes the network interfaces available on your system

# and how to activate them. For more information, see interfaces(5).

# The loopback network interface

auto lo

iface lo inet loopback

# The primary network interface

auto eth0 eth1

iface eth0 inet static

address 192.168.1.181

netmask 255.255.255.0

network 192.168.1.0

broadcast 192.168.1.255

gateway 192.168.1.1

# dns-* options are implemented by the resolvconf package, if installed

dns-nameservers 202.106.0.20

iface eth1 inet static

address 10.1.0.181

netmask 255.255.255.0

network 10.1.0.0

broadcast 10.1.0.255

/etc/hosts文件内容为:

127.0.0.1 omain localhost

192.168.0.181 rac1

192.168.0.182 rac2

192.168.0.191 rac1-vip

192.168.0.192 rac2-vip

10.10.10.181 rac1-priv

10.10.10.182 rac2-priv

# The following lines are desirable for IPv6 capable hosts

::1 ip6-localhost ip6-loopback

fe00::0 ip6-localnet

ff00::0 ip6-mcastprefix

ff02::1 ip6-allnodes

ff02::2 ip6-allrouters

ff02::3 ip6-allhosts

修改后:

127.0.0.1 omain localhost

192.168.1.181 rac1

192.168.1.182 rac2

192.168.1.191 rac1-vip

192.168.1.192 rac2-vip

10.1.0.181 rac1-priv

10.1.0.182 rac2-priv

# The following lines are desirable for IPv6 capable hosts

::1 ip6-localhost ip6-loopback

fe00::0 ip6-localnet

ff00::0 ip6-mcastprefix

ff02::1 ip6-allnodes

ff02::2 ip6-allrouters

ff02::3 ip6-allhosts

集群中所有节点的hosts文件应该保持一致.

/etc/network/interfaces和/etc/hosts文件修改后可使用

/etc/init.d/networking restart

或者重启操作系统使设置生效.

3 启动crs, 设置oracle中ip地址相关的设置.

3.1 启动crs, 并关闭随crs启动的应用程序

rac1:/u01/app/oracle/product/10.2.0/db_1/network/admin# /etc/init.d/ start

Startup will be queued to init within 90 seconds.

由于oracle所有应用设置为自动启动, 所以在crs启动时会试图启动所有的服务, 但是在对oracle相关的ip地址进行设置时需要crs处于运行状态而数据库, asm和node application处于停止状态, 所以需要我们参考1.2, 1.3, 1.4的内容关闭数据库, asm和node application.

3.2 使用oifcfg修改网卡设置, oifconfig可以被用来设置和查看网卡被oracle使用的方式.

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./oifcfg getif -global

eth0 192.168.0.0 global public

eth1 10.10.10.0 global cluster_interconnect

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./oifcfg setif -global eth0/192.168.1.0:public

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./oifcfg iflist

eth0 192.168.1.0

eth0 192.168.0.0

eth1 10.1.0.0

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./oifcfg delif -global eth0/192.168.0.0

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./oifcfg iflist

eth0 192.168.1.0

eth1 10.1.0.0

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./oifcfg getif -global

eth0 192.168.1.0 global public

eth1 10.10.10.0 global cluster_interconnect

rac2:/u01/app/oracle/product/10.2.0/crs/bin#

eth1:/10.1.0.0:cluster_interconnect

-bash: ./lifcfg: No such file or directory

rac2:/u01/app/oracle/product/10.2.0/crs/bin#

eth1:/10.1.0.0:cluster_interconnect

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./oifcfg getif -global

eth0 192.168.1.0 global public

eth1 10.10.10.0 global cluster_interconnect

eth1: 10.1.0.0 global cluster_interconnect

rac2:/u01/app/oracle/product/10.2.0/crs/bin#

eth1/10.1.0.0:cluster_interconnect

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./oifcfg getif -global

eth0 192.168.1.0 global public

eth1 10.10.10.0 global cluster_interconnect

eth1 10.1.0.0 global cluster_interconnect

eth1: 10.1.0.0 global cluster_interconnect

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./oifcfg delif -global eth1:

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./oifcfg delif -global eth1/10.10.10.0

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./oifcfg getif -global

eth0 192.168.1.0 global public

eth1 10.1.0.0 global cluster_interconnect

oifcfg iflist会显示当前使用的网卡及其子网设置, 而oifcfg getif -global 则会显示配置文件中的信息.

./oifcfg setif -global

./oifcfg setif -global

./lifcfg setif -global

3.3 修改vip地址

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./srvctl modify nodeapps -n rac1 -A

192.168.1.191/255.255.255.0/eth0

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./srvctl modify nodeapps -n rac2 -A

192.168.1.192/255.255.255.0/eth0

3.4 设置和, 检查这些文件中是否有指定原来ip的地方, 修改为更改后的ip地址, 在rac1的配置文件中包含了 192.168.0.181我修改成了192.168.1.181, rac2上的 也做了相应的修改.

3.5 启动node applications, asm, 数据库

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./srvctl start nodeapps -n rac1

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./srvctl start nodeapps -n rac2

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./srvctl start asm -n rac2

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./srvctl start asm -n rac1

rac2:/u01/app/oracle/product/10.2.0/crs/bin#

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./srvctl start database -d orcl

3.6 来看看我们的成果:

rac2:/u01/app/oracle/product/10.2.0/crs/bin# ifconfig -a
