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
