HomeLab/Ansible - Add New Host

First, make sure that root login is permitted on the host.

Use your favorite text editor.

sudo vim /etc/ssh/sshd_config

Inside the config file, set permit root login to yes

PermitRootLogin Yes

Restart SSH Service

/etc/init.d/ssh restart

If you have not set a password for root, do it now.

passwd

Now, if you have not generated an ssh key, do it now.

ssh-keygen -t rsa -b 4096

Send this key to the host.

ssh-copy-id root@ip.addr_of_host

Add the host to Ansible

vim /etc/ansible/hosts

my_host ansible_hosts=ip.addr_of_host

To make sure ansible can reach the host, ping it with this command.

ansible my_host -m ping

The output should look like this

my_host | SUCCESS => {

   "changed": false,
   "ping": "pong"

}
