Postgresql 9.4 replication not working

I have setup my replication as per https://www.digitalocean.com/community/tutorials/how-to-set-up-master-slave-replication-on-postgresql-on-an-ubuntu-12-04-vps.

When I start my slave and check for logs, it says

2016-03-17 04:03:02 UTC LOG:  shutting down
2016-03-17 04:03:02 UTC LOG:  database system is shut down

2016-03-17 04:03:03 UTC LOG:  incomplete startup packet

My pg_hba.conf entry is as follows:

 host    replication     replication     10.50.80.12/32          trust

My recovery.conf is as follows:

standby_mode = 'on'
primary_conninfo = 'host=10.50.80.11 port=5432 user=replication password=replication'

But when I do,

SELECT * 
FROM pg_stat_replication; 

nothing is shown.

Please help if I am missing something.

Also, do I have to create the databases in slave as in master?
