sudo cat ~/.ssh/id_rsa.pub

copy the above output.
3. Now login into target node where you want to install LAMP stack, execute the below command to open the file
sudo vi /home/ubuntu/.ssh/authorized_keys
type shift A and then enter now 
    and paste the key in the above file. please do not delete any existing values in this file.

sudo vi /etc/ansible/hosts
