oracle RAC 11gR2 修改ip地址

有一个很急的项目上线，rac实施由我在公司安装，ip是虚构的，要求在2-3小时内搞定，所以ip是我随便写的。

目前服务器已经运到局点，马上实行修改正式ip。 由于最近在负责项目，逐渐陌生了dba知识，哈哈。好久没有写blog老。

 

[oracle@racdb1 ~]$ hostname
racdb1
[oracle@racdb1 ~]$ more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1		racdb1 localhost.localdomain localhost
::1		localhost6.localdomain6 localhost6

# Public
192.168.102.124    racdb1
192.168.102.125    racdb2
# Private
192.168.10.124    racdb1-priv
192.168.10.125    racdb2-priv
# Virtual
192.168.102.126	   racdb1-vip
192.168.102.127	   racdb2-vip
 
#scan
192.168.102.128   racdb-scan
