# Databases

Strapi gives you the option to choose the most appropriate database for your project. It currently supports **PostgreSQL**, **MongoDB**, **SQLite**, **MySQL** and
**MariaDB**. The following documentation covers how to install these databases locally (for development purposes) and on various hosted or cloud server solutions (for staging or production purposes).

::: tip
Deploying **Strapi** itself is covered in the [Deployment Guide](deployment.md).
:::

## SQLite Installation

SQLite is the default ([Quick Start](../getting-started/quick-start.md)) and recommended database to quickly create an app locally.

### Install SQLite locally

Simply use one of the following commands.

:::: tabs

::: tab yarn

```bash
yarn create strapi-app my-project --quickstart
```

:::

::: tab npx

```bash
npx create-strapi-app my-project --quickstart
```

:::

::::

This will create a new project and launch it in the browser.

::: tip
The [Quick Start Guide](../getting-started/quick-start.md) is a complete step-by-step tutorial

::: tab "Ubuntu 18.04"

#### Install MongoDB on Ubuntu

Follow these steps to [install MongoDB onto your Ubuntu](https://docs.mongodb.com/manual/administration/install-on-linux/) environment:

1. Import a public key to ensure your MongoDB is authentic:

```bash
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4
```

2. Next, add the repository for 18.04. Repositories for other versions of Ubuntu are found [here](https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/).

```bash
echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list
```

3. Reload the local package database:

```bash
sudo apt-get update
```

4. Install the stable release MongoDB package

```bash
sudo apt-get install -y mongodb-org
```

5. Get the `mongod` process running in order to connect and use MongoDB:

```bash
sudo service mongod start
```

6. Confirm the MongoDB status:

```bash
service mongod status
```

7. The last step is to enable automatically starting MongoDB when your computer boots:

### Install on Atlas: MongoDB Atlas

Follow these steps to configure a local Strapi project to use a [MongoDB Atlas](https://www.mongodb.com/cloud/atlas) free 512 MB account in production. (Please see [MongoDB Atlas Documentation](https://docs.atlas.mongodb.com/getting-started/) if you have any questions.)

- You must have already [created your Strapi project using MongoDB](databases.md#install-strapi-locally-with-mongodb).
- You must have already created a [free MongoDB Atlas account](https://www.mongodb.com/cloud/atlas).

#### 1. Log in to your account to create a **Project** and a **Cluster**

- First you need to `Create a new Project`.
- Then click `Build a Cluster`, from the options page:
  - Choose **AWS** as your **Cloud Provider & Region**.
  - Select a **Region**. (Note: some **Regions** do not have a _free tier_.)
  - In **Cluster Tier**, select **Shared Sandbox**, _Tier_ `MO`.
  - In **Cluster Name**, name your cluster.
- Click the green `Create Cluster` button. You will get a message that says, "_Your cluster is being created..._"

#### 2. Next, click on the `Database Access` in the left menu (under `Overview`):

- Click the green `+ ADD NEW USER` button:
  - Enter a `username`.
  - Enter a `password`.
  - Under `User Privileges` ensure **`Read and write to any database`** is selected. Then click `Add User` to save.

#### 3. Then `whitelist` your IP address. Click into `Network Access`, under `Security` in the left menu:

- Click the green `+ ADD IP ADDRESS`

  - Click `ADD CURRENT IP ADDRESS` or **manually** enter in an IP address to `whitelist`.
  - Leave a comment to label this IP Address. E.g. `Office`.
  - Then click the green `Confirm` button.
  - Delete the `0.0.0.0/0` configuration after testing the connection.

  ::: tip
  If for any reason you need to test the configuration or other aspect of your connection to the database, you may want to set back the `Allow Access from Anywhere`. Follow this steps:
  :::

  - Click the green `+ ADD IP ADDRESS`
    - Next add `0.0.0.0/0` in the `Whitelist Entry`. **Note:** In permanent projects you would configure this with the appropriate IP addresses.
    - Leave a comment to label this IP Address. E.g. `Anywhere`.
    - Click `Confirm`. Then wait until the status turns from `Pending` to `Active`.

  ::: tip
  If you are serving you Strapi project from a known IP Address then follow the following steps to `allow Network Access`.
  :::

  - **Manually** enter in an IP address to `whitelist`, for your Strapi server.
  - Leave a comment to label this IP Address. E.g. `Heroku Server`
  - Then click the green `Confirm` button.

#### 4. Retrieve database credentials

MongoDB Atlas automatically exposes the database credentials into a single environment variable accessible by your app. To locate it, follow these steps:

- Under `Atlas` in the left-hand, click on `Clusters`. This should take you to your `cluster`. Next, click `CONNECT` and then `Connect Your Application`.
- Under `1. Choose your driver version`, select **DRIVER** as `Node.js` and **VERSION** as `2.2.12 or later`.
  ::: warning
  You **must** use `Version: 2.2.12 or later`.
  :::
- This should show a **Connection String Only** similar to this:

`mongodb://paulbocuse:<password>@strapi-heroku-shard-00-00-oxxxo.mongodb.net:27017,strapi-heroku-shard-00-01-oxxxo.mongodb.net:27017,strapi-heroku-shard-00-02-oxxxo.mongodb.net:27017/test?ssl=true&replicaSet=Strapi-Heroku-shard-0&authSource=admin&retryWrites=true&w=majority`

::: warning
Please note the `<password>` after your `username`. In this example, after `mongodb://paulbocuse:`. You will need to replace the `<password>` with the password you created earlier for this user in your **MongoDB Atlas** account.
:::

#### 5. Update and replace your existing `/database.json` config file for the appropriate environment (development | production).

Replace the contents of `/database.json` with the following and replace **< password >** with the password of the user of your database you created earlier:

`Path: ./config/environments/(development|production)/database.json`.

```json
{
  "defaultConnection": "default",
  "connections": {
    "default": {
      "connector": "strapi-hook-mongoose",
      "settings": {
        "uri": "mongodb://paulbocuse:<password>@strapidatabase-shard-00-00-fxxx6c.mongodb.net:27017,strapidatabase-shard-00-01-fxxxc.mongodb.net:27017,strapidatabase-shard-00-02-fxxxc.mongodb.net:27017/test?ssl=true&replicaSet=strapidatabase-shard-0&authSource=admin&retryWrites=true&w=majority"
      },
      "options": {
        "ssl": true
      }
    }
  }
}
```

::: warning NOTE
The above configuration will create a database called `strapi`, the _default database_ Strapi sets for any **MongoDB** database. If you would like to name your database something else, add the following **key:value pair** into your **"settings":** located in your `database.json` file.

`"database": "my-database-name"`

:::

::: danger WARNING
We recommend replacing sensitive (eg. "URI string" above) information in your database.json files before uploading your project to a public repository such as GitHub. For more information about using environment variables, please read [dynamic configurations](../concepts/configurations.md#dynamic-configurations).

:::

You are now ready use Strapi locally or to deploy your project to an external hosting provider and use MongoDB Atlas as your database server.
