# Easy Steps to Install OpenStack/DevStack All-in-One

Hi!👋 I'm excited to share how I set up OpenStack using **DevStack** on local machine. If you’re just getting started with OpenStack, this guide might help you spin up your own testing environment.

> ⚠️ **Disclaimer**: This is a **minimal, all-in-one installation** intended for development and testing purposes only. **Do not use this setup in production environments.**

## What is DevStack?

DevStack is a series of extensible scripts used to quickly bring up a complete OpenStack environment for development or testing purposes. It’s not recommended for production use, but it's perfect for labs and learning.

### Why Use DevStack?

DevStack is a great way to:

* Learn OpenStack hands-on
    
* Test and experiment with OpenStack components
    
* Set up a local cloud lab quickly
    

<mark>But again, it’s not designed for production workloads, so test it as your cloud playground.</mark>

## My System Info

Before diving in, I’ve already installed a VM on my local machine. Here’s the OS I used:

## Setup Steps

### 1\. Update the system

Make sure your packages are up to date:

```plaintext
sudo apt-get update -y
```

### 2\. Clone my DevStack setup repo

I've uploaded a custom DevStack configuration script to GitHub. Feel free to clone and use it.

```plaintext
git clone https://github.com/linnlattoo-cloud/devstack.git
cd devstack
```

### 3\. Make the setup script executable

```plaintext
chmod +x devstack_setup.sh
```

### 4\. Optional: Customize your setup

You can change passwords for:

* Database
    
* `admin`
    
* `service`
    
* RabbitMQ
    

Just edit the `local.conf` file by using vim editor or nano inside the repo before starting the install.

### 5\. Run the setup script

This will download and install OpenStack and take **20–30 minutes**.

```plaintext
./devstack_setup.sh
```

### Accessing OpenStack

Once the setup is done, you can log in to the OpenStack dashboard (Horizon) ([`http://your-server(vm)-ip/dashboard`](http://your-server-ip/dashboard)) using the `admin` user and the admin password you defined in `local.conf`.

## Cleaning Up

Need to remove everything? Just run:

```plaintext
./clean.sh
```

This will clean up your DevStack environment so you can start fresh if needed.
