Linux下启动oracle分为以下两步：
首先登陆服务器，切换到oracle用户。
[admin@dataserver ~]$ su - oracle
密码：
[oracle@dataserver ~]
接下来，检查oracle监听器运行状态，通过lsnrctl status命令查看。
[oracle@dataserver ~]$ lsnrctl status

上述反馈的结果即为oracle监听没有启动，下面执行启动监听，通过命令lsnrctl start，结果如下：
[oracle@dataserver ~]$ lsnrctl start

上述反馈为监听启动失败，是因为其监听的IP30.85.227.24，并非服务器的IP，所以需要调整这个IP为服务器当前的IP。
在oracle用户下，进入目录/u01/app/oracle/product/11.2.0/dbhome_1/network/admin，修改listener.ora文件。注意这个目录因具体服务器而异。 
listener.ora文件打开，内容如下，调整其中的HOST IP即可。
