解决办法：

   在 /etc/hosts文件中增加一行：

   127.0.0.1 localhost

 

   之后，再次启动，问题解决。

该问题，可以参考 Starting TNS Listener or LSNRCTL Start Yields TNS-12541, Linux Error: 111: Connection Refused (文档 ID 343295.1)

 

原因：

 

1. There is possibly an incorrect IP Address specified for the host in the /etc/hosts file.
For example:
192.168.101.101 prod1.us.oracle.com prod1
Whereas the actual ip address for the host "prod1.us.oracle.com" is 192.168.101.110

2. Also, the localhost reference may be incorrect or missing from the /etc/hosts file.

3. Oracle may not have read access to /etc/nsswitch.conf file.
