仔细检查这二配置文件，无语法错误。且tns文件都是使用主机名进行连接，怀疑可能/etc/hosts中ip配置有问题。

--查看/etc/hosts内容

[oracle@gc1 admin]$ vi /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

# Do not remove the following line, or various programs

::1 localhost6.localdomain6 localhost6

192.168.188.116 gc1

192.168.8.115 gc2

--查看当前系统ip

[root@gc1 ~]# ifconfig

这二ip不同，于是root用户修改/etc/hosts中ip地址信息，如下：

[oracle@gc1 oradata]$ su - root

Password:

[root@gc1 ~]# vi /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 node1 localhost.localdomain localhost

::1 localhost6.localdomain6 localhost6

# 192.168.188.116

10.1.55.129 gc1

192.168.8.115 gc2

修改保存后，再启动监听，，成功

[oracle@gc1 ~]$ lsnrctl start
