监听器启动时报错：TNS-12537: TNS:connection closed/ TNS-00507: Connection closed

监听器启动时报错：

版本为：LSNRCTL for Linux: Version 10.2.0.1.0

[oracle@ocm1 ~]$ lsnrctl start

经查询是127.0.0.1                localhost.localdomain localhost   这一条没写对，127后面少了0，更改后正常。

   [oracle@ocm1 bin]$ sudo vi /etc/hosts

127.0.0.1                localhost.localdomain localhost

::1             localhost6.localdomain6 localhost6

192.168.57.217   ocm1.bys.com ocm1

修改后重新启动监听器，正常。
