测试方案：
ping  127.0.0.1  可以ping通
ping  localhost  不通

说明是主机映射的原因。

解决方法： 修改etc/hosts 文件

[oracle@bogon ~]$ su - root
Password:
[root@bogon ~]# cd ..
[root@bogon /]# cd ..
[root@bogon /]# cd etc
[root@bogon etc]# cat hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               bogon.localdomain bogon

在hosts文件中追加下面一行就OK了：
127.0.0.1              localhost.localdomain  localhost
