11gr2 rac改IP系列之四：修改私网IP为其它IP

Guang Cai Li发表于 2023-09-17 06:59:48

————————–
修改私有ip为其它网段IP。
—————–修改前：
192.168.58.1 bys1-priv.bys.com bys1-priv
192.168.58.2 bys2-priv.bys.com bys2-priv
—————–修改后：
192.168.59.1 bys1-priv.bys.com bys1-priv
192.168.59.2 bys2-priv.bys.com bys2-priv
参考MOS文档：How to Modify Private Network Information in Oracle Clusterware (文档 ID 283684.1)
从11.2 Grid Infrastructure开始，私有网络配置存储在OCR和gpnp配置文件中。如果专用网络不可用或其定义不正确，CRSD进程将不会启动，并且后续不能对OCR进行更改。注意，不支持手动修改gpnp配置文件。
——–目录
1.备份gpnp配置文件
2.查看当前集群是运行状态及OS层面网卡信息
3.查看并修改私网配置信息–单个节点进行
4.关闭CRS–两个节点均进行
5.OS层面修改IP并修改/etc/hosts中记录（两个节点均修改）并测通
6.重新启动集群
7.删除原有私网信息并验证
8.检查集群状态

具体步骤：–仅显示节点1，节点2同样步骤。

1.备份gpnp配置文件
$ cd $GRID_HOME/gpnp/<hostname>/profiles/peer/
—
[grid@bys1 ~]$ cd /u01/11.2.0/grid/gpnp/bys1/profiles/peer/
[grid@bys1 peer]$ ls
pending.xml profile.old profile_orig.xml profile.xml
[grid@bys1 peer]$ cp profile.xml profile.xmlbak

[grid@bys2 ~]$ cd /u01/11.2.0/grid/gpnp/bys2/profiles/peer/
[grid@bys2 peer]$ cp profile.xml profile.xmlbak

2.查看当前集群是运行状态及OS层面网卡信息
[grid@bys2 peer]$ crsctl stat res -t

3.查看并修改私网配置信息–单个节点进行
—
[grid@bys1 peer]$ oifcfg getif
eth0 192.168.57.0 global public
eth1 192.168.58.0 global cluster_interconnect
[grid@bys1 peer]$ oifcfg iflist
eth0 192.168.57.0
eth1 192.168.58.0
eth1 169.254.0.0

[grid@bys1 peer]$ oifcfg setif -global eth1/192.168.59.0:cluster_interconnect
[grid@bys1 peer]$ oifcfg getif
eth0 192.168.57.0 global public
eth1 192.168.58.0 global cluster_interconnect
eth1 192.168.59.0 global cluster_interconnect

##############
4.关闭CRS–两个节点均进行
[root@bys1 ~]# crsctl stop crs
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on ‘bys1’
………………
CRS-2793: Shutdown of Oracle High Availability Services-managed resources on ‘bys1’ has completed
CRS-4133: Oracle High Availability Services has been stopped.
[root@bys1 ~]# crsctl disable crs
CRS-4621: Oracle High Availability Services autostart is disabled.

###############
5.OS层面修改IP并修改/etc/hosts中记录（两个节点均修改）并测通

—————–修改前：
192.168.58.1 bys1-priv.bys.com bys1-priv
192.168.58.2 bys2-priv.bys.com bys2-priv
—————–修改后：
192.168.59.1 bys1-priv.bys.com bys1-priv
192.168.59.2 bys2-priv.bys.com bys2-priv

[root@bys2 network-scripts]# ifconfig

6.重新启动集群

[root@bys2 ~]# crsctl enable crs
CRS-4622: Oracle High Availability Services autostart is enabled.
[root@bys2 ~]# crsctl start crs
CRS-4123: Oracle High Availability Services has been started.

###############
7.删除原有私网信息并验证
[grid@bys1 ~]$ oifcfg getif
eth0 192.168.57.0 global public
eth1 192.168.58.0 global cluster_interconnect
eth1 192.168.59.0 global cluster_interconnect
[grid@bys1 ~]$ oifcfg delif -global eth1/192.168.58.0:cluster_interconnect
[grid@bys1 ~]$ oifcfg getif
eth0 192.168.57.0 global public
eth1 192.168.59.0 global cluster_interconnect

###############
8.检查集群状态
[grid@bys1 ~]$ gpnptool get
