# Terraform and Ansible Project for Infrastructure and Configuration Management
## Overview
This project provides Terraform configurations to create AWS EC2 instances for Ansible practice and sample Ansible playbooks to perform common tasks on these instances.
### Terraform Files
- **main.tf**: Creates EC2 instances with Amazon Linux 2023 and Ubuntu 22.04, along with a security group allowing SSH (22) and HTTP (80) connections.
- **variables.tf**: Defines variables for instance tags, key name, user, AMIs, instance type, and AWS credentials.
- **inventory.txt**: Specifies the Ansible inventory with groups and variables.
- **ansible.cfg**: Configuration file for Ansible settings.
### Ansible Playbooks
- **install_docker.yml**: Installs and configures Docker on servers.
- **setup_web_server.yml**: Sets up a web server using Apache.
- **create_user.yml**: Creates a user on servers.
- **install_nginx.yml**: Installs and configures Nginx.
- **install_mysql.yml**: Installs and configures MySQL.
- **install_python.yml**: Installs Python and pip on servers.
## Prerequisites
- Terraform installed
- AWS CLI configured with appropriate credentials
- Ansible installed
- SSH key pair created and added to the AWS account
# Usage
## Step 1: Terraform Setup
1. **Initialize Terraform**
```bash
terraform init
terraform apply
## Step 2: Ansible Setup
### Update Inventory File
Ensure the inventory.txt file contains the correct private IP addresses of the created EC2 instances.
### Update Ansible Configuration
Make sure ansible.cfg is correctly configured.
**Step 3: Running Ansible Playbooks**
**Connectivity Test**
```
ansible-playbook connectivity-test-playbook.yaml
```
**Install Docker**
```
ansible-playbook install_docker.yaml
```
**Copy File**
```
ansible-playbook copyfile-playbook.yaml
```
**Create a User**
```
ansible-playbook create_user.yaml
```
**Install and Configure Nginx**
```
ansible-playbook install_nginx.yaml
```
**Install and Configure MySQL**
```
ansible-playbook install_mysql.yaml
```
**Install Python and pip**
```
ansible-playbook install_python.yml
```

```
## B. Other Commands:
- **Ping all hosts**
```
ansible all -m ping
```
- **Check free memory on all hosts**
```
ansible all -a "free -m"

- **Check uptime on all hosts**
```
ansible all -a "uptime"
```
- **Restart a service**
