$ lsnrctl start

The listener supports no services
The command completed successfully

如图所示：


这样启动后远程连接会报错：
oracle ORA-12514:TNS:listener does not currently know of service requested in connect descriptor

问题原因：数据库实例没注册到listener

解决方法：

在listener.ora里面添加了一行

SID_LIST_LISTENER =  
(SID_LIST =  
  (SID_DESC =  
  (GLOBAL_DBNAME = orcl)
  (SID_NAME = orcl)
  )
)

注：里面的orcl根据你安装的数据库实例名确定，我用此法解决了这个报错。
