linux 安装 oracle 的时候，./runInstaller 启动报错  

PRVF-0002 : could not retrieve local node name

该错误主要是由于hosts文件配置问题：
vi /etc/hosts

修改hosts文件中加入服务器ip以及hostname即可.

#
# hosts         This file describes a number of hostname-to-address
#               mappings for the TCP/IP subsystem.  It is mostly
#               used at boot time, when no name servers are running.
#               On small systems, this file can be used instead of a
#               "named" name server.
# Syntax:
#    
# IP-Address  Full-Qualified-Hostname  Short-Hostname
