上篇 RAC 修改 IP 介绍的是修改VIP,SCAN IP ,PUBLIC IP . 现在要修改的是私有网络的IP
修改 private ip
1 确保crs集群是打开的
可以用olsnodes –s 检查集群的状态
[root@sharkdb-rac-01 network-scripts]# olsnodes -s
sharkdb-rac-01 Active
sharkdb-rac-02 Active
2 检查网卡信息
[root@sharkdb-rac-01 network-scripts]# oifcfg getif
eth2 192.168.3.0 global cluster_interconnect
eth1 192.168.7.0 global public
3 修改私有网卡IP --添加方法
[root@sharkdb-rac-01 network-scripts]# oifcfg setif -global ethn2/192.168.8.0:cluster_interconnect
4 修改成功
[root@sharkdb-rac-01 network-scripts]# oifcfg getif
eth2 192.168.3.0 global cluster_interconnect
eth1 192.168.7.0 global public
ethn2 192.168.8.0 global cluster_interconnect
5 删除旧的私有网卡
[root@sharkdb-rac-01 network-scripts]# oifcfg delif -global eth2
[root@sharkdb-rac-01 network-scripts]# oifcfg getif
eth1 192.168.7.0 global public
ethn2 192.168.8.0 global cluster_interconnect
6 关闭CRS
[root@sharkdb-rac-01 network-scripts]# crsctl stop crs
7 修改私有网卡的系统IP地址
[root@sharkdb-rac-01 ~]# ifconfig
eth1 Link encap:Ethernet HWaddr 08:00:27:C8:85:B8
inet addr:192.168.7.203 Bcast:192.168.7.255 Mask:255.255.255.0

8 重启系统
reboot
9 检查是否报错了 ?
我上面 多输入个N 字母 后面起不来了
