# ansible-01
## Basic Inventory & Ad-Hoc Commands
## **Project Overview**
This project sets up an Ansible inventory file and demonstrates running ad-hoc commands on remote Linux Mint machines.
---
## **Step 1: Setting Up SSH Key Authentication**
To enable password-less SSH access, follow these steps:
### **1. Generate an SSH Key on WSL**
```bash
ssh-keygen -t rsa -b 4096 -C "ansible@wsl"
```
Press **Enter** to accept the default file location (`~/.ssh/id_rsa`).
Do **not** set a passphrase (press Enter twice).
### **2. Copy the Key to the Managed Nodes**
Replace `user` and `ip_address` with your actual details:
```bash
ssh-copy-id user@ip_address
```
Repeat this for each Linux Mint machine.
If `ssh-copy-id` is unavailable, manually copy the key:
```bash
cat ~/.ssh/id_rsa.pub
```
On the remote machine, add the key to `~/.ssh/authorized_keys`:
```bash
echo "PASTE_THE_KEY_HERE" >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
```
### **3. Test SSH Access**
```bash
ssh user@ip_address
```
If the login works without a password, SSH key authentication is set up.
---
## **Step 2: Create an Ansible Inventory File**
Create an `inventory.ini` file in the project directory:
```ini
[linux_mint]
mint-desktop ansible_host=192.168.1.10 ansible_user=user
mint-vm ansible_host=192.168.1.20 ansible_user=user
```
Replace IP addresses and usernames with your actual setup.
---
## **Step 3: Test Ansible Connection**
Run the following command to check connectivity:
```bash
ansible all -i inventory.ini -m ping
```
If successful, each host will return a `pong` response.
---
## **Step 4: Running Ad-Hoc Commands**
Execute remote commands without writing a playbook:
1.**Check system uptime:**
```bash
ansible linux_mint -i inventory.ini -m shell -a "uptime"
```
2.**Check disk usage:**
```bash
ansible linux_mint -i inventory.ini -m shell -a "df -h"
```
3.**List logged-in users:**
```bash
ansible linux_mint -i inventory.ini -m shell -a "who"
```
