I have grid installed in my pc but the problem is LISTENER does not start automatically. I have to start listener manually and then only LISTENER get started. But before starting listener if you check the status first then here is what is shows if you try LSNRCTL STATUS. I followed following url but it did not work for me :
Linux Error: 111: Connection refused LSNRCTL
My question is how should I make the listener run automatically?
Please check the necessary required information below : –
[grid@netsystemsolution ~]$ lsnrctl status

TNS-12560: TNS:protocol adapter error

If you check the status of the listener from crvctl then this is what it shows:
[grid@netsystemsolution ~]$ srvctl status listener
PRCN-2044 : No listener exists
[grid@netsystemsolution ~]$ srvctl config listener

I followed the following url for listener.ora,sqlnet.ora and tnsnames.ora configuration

Now I started listener manually with lsnrcrl command and here is what it shows:
[grid@netsystemsolution admin]$ lsnrctl start

Now if you wait like 10 to 15 seconds, after this then this is what it shows:

I wonder where is the problem? Why I have to start listener manually? Why listener does not start automatically ? Please suggest.

The easiest way to register your listener at Oracle Grid Infrastructure is to run
netca. If you want to configure the listener "LISTENER" you have to make sure that it does not exist in the listener.ora yet.One more thing: You should always configure your own host in the
/etc/hostsfile.
