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).
If you already have MongoDB installed locally and running as a background service, you may skip to [Install Strapi locally with MongoDB](#install-strapi-locally-with-mongodb). (If you have additional questions, please see the official [MongoDB documentation](https://docs.mongodb.com/manual/installation/#tutorial-installation). )
Please complete the installation steps appropriate to your operating system.
Follow these steps to [install MongoDB onto your Windows 10](https://docs.mongodb.com/manual/tutorial/install-mongodb-on-windows/) environment (The Windows Sub-System for Linux (WSL) is unsupported by MongoDB):
1. Download the `MongoDB Community Edition Server` for Windows [here](https://www.mongodb.com/download-center/community?jmp=docs). Select `MongoDB Community Server` and verify the options that match your computer. Then `Download` the package and follow the installation instructions to complete the process.
2. After successfully installing MongoDB, the MongoDB service is started. To begin using MongoDB, connect a mongo.exe shell to the running MongoDB instance.
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/).
You have successfully installed Strapi with MongoDB on your local development environment. You are now ready to [create your first user](/3.0.0-beta.x/getting-started/quick-start.html#_3-create-an-admin-user).
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.)
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:
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`.
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.
Replace the contents of `/database.json` with the following and replace **<password>** with the password of the user of your database you created earlier:
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.
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](/3.0.0-beta.x/configurations/configurations.html#dynamic-configurations).
