This guide will help you set up Ansible on an Ubuntu system.

• An Ubuntu system
• SSH access to a remote server

1. Install Ansible on the Ubuntu system:

sudo apt update
sudo apt install -y ansible

2. Create an inventory file, for example, inventory.ini, and add your server details:

[my_servers]
my_server ansible_host=18.209.59.137

3. Create an Ansible configuration file, ansible.cfg, and add the following content:

[defaults]
inventory = inventory.ini
remote_user = ubuntu
private_key_file = ../deployer
host_key_checking = False
retry_files_enabled = False

4. Test the Ansible connection to the remote server with the following command:

ansible my_servers -m ping

Replace 'my_servers' with the appropriate group name

from your inventory file.

Below is a brief explanation of the additional Ansible files found in the 6.8 directory:

• ansible.cfg: This is the Ansible configuration file that contains settings such as the inventory file path, remote user, private key file, host key checking, and retry file settings.
• apache.yaml: This Ansible playbook installs the Apache web server on the target machines. To run the playbook, use the following command:

ansible-playbook apache.yaml

• host_vars.yml: This file contains host-specific variables for Ansible configuration. It allows you to define variables for each host in your inventory.
• inventory.ini: This is the Ansible inventory file that contains the server details, such as the server's hostname and IP address.
• jenkins.yaml: This Ansible playbook installs Jenkins on the target machines. To run the playbook, use the following command:

ansible-playbook jenkins.yaml

• node.yml: This Ansible playbook installs Node.js on the target machines. To run the playbook, use the following command:

ansible-playbook node.yml
