Ansible Install

This repo provides a simple way to set up OpenSSH and configure public keys on multiple Ubuntu machines to prepare them for Ansible automation.

Features

✅ Installs OpenSSH on target Ubuntu machines.
✅ Adds your public SSH keys for seamless Ansible access.
✅ Includes a sample hosts.txt file for Ansible inventory.

Step 1: Clone the Repository

To get started, clone this repository to your local machine:

git clone https://github.com/michaelbolanos/ansible-install.git
cd ansible-install/scripts

---

Step 2: Configure Your Hosts File

Edit the hosts.txt file to include the IP addresses or hostnames of the machines you want to manage with Ansible:

192.168.1.100
192.168.1.101
192.168.1.102

---

Step 3: Install OpenSSH via Curl or Wget

Run the following command on each Ubuntu machine to install OpenSSH.

Using curl

curl -sSL https://raw.githubusercontent.com/michaelbolanos/ansible-install/main/scripts/install_ssh.sh | bash

Using wget

wget -qO- https://raw.githubusercontent.com/michaelbolanos/ansible-install/main/scripts/install_ssh.sh | bash

---

Step 4: Copy SSH Keys to Remote Machines

To enable passwordless SSH authentication, use the provided ssh-keys.sh script. Run this from your control machine:

bash ssh-keys.sh

This script will:

# Copy SSH public key to each host in hosts.txt
while read -r host; do
    ssh-copy-id -i ~/.ssh/id_rsa.pub "ubuntu@$host"
done < hosts.txt

• Copies your SSH public key to each host listed in hosts.txt
• Ensures secure key-based authentication

---

Step 5: Verify SSH Access

Once keys are copied, test SSH access to the remote machines:

ssh ubuntu@192.168.1.100

If login works without a password prompt, you're ready to use Ansible! 🎉

---

Next Steps: Set Up Ansible

Now that SSH is configured, install Ansible and begin automating your infrastructure.

sudo apt update && sudo apt install -y ansible

You can now create an Ansible inventory file and start managing your machines
