今天准备打开我的debian下的oracle 10gR2来做一些java测试, 可是忘记了上次关机以来我的网络以及vmware都做了调整, 竟然无法直接访问. 就想把debian虚拟机使用的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
NAME=ora.orcl.db
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac2

NAME=ora.orcl.orcl1.inst
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac1

NAME=ora.orcl.orcl2.inst
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac2

NAME=ora.rac1.ASM1.asm
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac1

NAME=ora.rac1.LISTENER_RAC1.lsnr
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac1

NAME=ora.rac1.gsd
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac1

NAME=ora.rac1.ons
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac1

NAME=ora.rac1.vip
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac1

NAME=ora.rac2.ASM2.asm
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac2

NAME=ora.rac2.LISTENER_RAC2.lsnr
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac2

NAME=ora.rac2.gsd
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac2

NAME=ora.rac2.ons
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac2

NAME=ora.rac2.vip
TYPE=application
TARGET=ONLINE
STATE=ONLINE on rac2

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/init.crs 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 localhost.localdomain 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 localhost.localdomain 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/init.crs 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 eth0/192.168.1.0ublic
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# ./lifcfg setif -global eth1:/10.1.0.0:cluster_interconnect
-bash: ./lifcfg: No such file or directory
rac2:/u01/app/oracle/product/10.2.0/crs/bin# ./oifcfg setif -global 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# ./oifcfg setif -global 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.

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listener.ora和tnsnames.ora, 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listener.ora包含了 192.168.0.181我修改成了192.168.1.181, rac2上的
listener.ora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:
