分析：

[root@c1 oracle]# hostname
c1
[root@c1 oracle]#cat /etc/hosts

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain localhost
::1             localhost6.localdomain6 localhost6

192.168.1.161   c1.bjqtd.com

192.168.1.162   c2.bjqtd.com

原来hosts文件与主机名不匹配，后来想想，开始的时候用的主机名是c1,c2,后来因为要做双机，改为了c1.bjqtd.com,c2.bjqtd.com

解决方法：

[root@c1 oracle]# vi/etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain localhost
::1             localhost6.localdomain6 localhost6
192.168.1.161   c1.bjqtd.com  c1
192.168.1.162   c2.bjqtd.com  c2

保存，继续配置监听，下回可不要这么粗心咯！！
