oracle12c安装报错：PRVF-0002的解决方法

./runInstaller 

启动图形化报错 

PRVF-0002 : Could not retrieve local nodename. 

查看了一下报错信息： 

[root@test68 OraInstall2013-09-06_04-43-39AM]# cat installActions2013-09-06_04-43-39AM.log 

后几行报错： 

SEVERE: [FATAL] PRVF-0002 : Could not retrieve local nodename. 
Refer associated stacktrace #oracle.install.commons.util.exception.DefaultErrorAdvisor:37 
INFO: Advice is ABORT 
SEVERE: Unconditional Exit 
INFO: Adding ExitStatus FAILURE to the exit status set 
INFO: Finding the most appropriate exit status for the current application 
INFO: Exit Status is -1 
INFO: Shutdown Oracle Database 12c Release 1 Installer 

猜测是找不到主机名的对应ip 

修改了下/etc/hosts 

127.0.0.1 localhost.localdomain localhosttest68 
::1 localhost6.localdomain6 localhost6 test68 
10.0.5.68 test68 

再运行就OK了
