Add a node in Ansible

Question

I have installed ansible on CentOS and now I want to add a server that is to manage or add another node to it. How do I do that?

Answer 1

Follow these steps @Ruth:

• Generate ssh key

ssh-keygen

• Check the ip of your node using ifconfig

• copy public key of Ansible server to its nodes. Use the command below:

ssh-copy-id -i root@<ip address of your node machine>

• use any editor to write your inventory or specify the IP addresses of your nodes grouped under ‘test-servers’

vi /etc/ansible/hosts

• Check the IP of your host

cat /etc/ansible/hosts

And you're done!
