Install Ansible

Debian
sudo apt-get install ansible

CentOS
sudo yum install ansible (EPEL)

Generate keys

If you do not already have an SSH key pair that you would like to use for Ansible administration, we can create one now on your Ansible, locate in Wazuh Manager host and run:

$ ssh-keygen

Choose ~/.ssh/id_rsa_ansible as output.

Enable ssh-agent and register de key:

$ eval "$(ssh-agent -s)"
$ ssh-add ~/.ssh/id_rsa_ansible

Copy ~/.ssh/id_rsa_ansible.pub content into the .ssh/authorized_keys host where you want to deploy Wazuh Agents in.

Configuring Ansible Hosts

Open the file with root privileges:

$ sudo nano /etc/ansible/hosts

Add destination hosts:

[wazuh-manager]
10.0.0.51

[wazuh-agent]
10.0.0.123
10.0.0.122
10.0.0.121

[elastic-stack]
10.0.0.124

cd ~
git clone https://github.com/wazuh/wazuh-ansible/

Create in your home o preferred folder the file agent.yml with the content:
