$ lsnrctl start

报错提示:

The listener supports no servicesThe 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解决方法一：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。解决方法二：登录数据库：$sqlplus / as sysdba显示服务名：SQL>show parameter service_names强制注册服务：SQL>alter system register;查看监听状态：$lsnrctl status
