1.启动监听器
[root@localhost ~]# lsnrctl start //启动监听
2.出现以下代码：

Linux Error: 1: Operation not permitted
Listener failed to start. See the error message(s) above...
根据大意提示没有权限。
3.The listener must be started using the same account you used to install Oracle. Typically, this account is named 'oracle'.
Using sudo, the command line should be:
sudo -H -u oracle /u01/app/oracle/product/10.2.0/db_1/bin/lsnrctl start
(btw, I don't think that using Ubuntu to run an Oracle database is supported by Oracle)
从国外某网站找的的答案，大意是启动listener 必须是安装oracle的用户，不是root用户。
4.切回oracle用户
[root@localhost ~]# exit //退出root用户
[oracle@localhost ~]$ lsnrctl start
