Hello, after a startup attempt please post the output of the following command:
netstat -tulpn | grep 1521

And include the relevant part of the
/u01/app/oracle/diag/tnslsnr/term1/listener/alert/log.xml

And
 /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
would be interesting as well.

Plus give more details about your OS.

I'm never a fan of using hostname in the Oracle config files.  I always prefer using the IP address.

Check /etc/hosts for term1.localdomain.  Odds are the issue is there.
is your database started?

run

>ps -ef | grep pmon

to see if your database is running

and also run

>lsnrctl stat

to check your listener
>>is your database started?

What does that have to do with the listener not starting?

>>to check your listener

That is sort of the reason for the question...  It isn't starting so the status will show nothing.
