# Installing MongoDB & mongosh — MongoDB

Source: https://www.geekswithgeeks.com/en/mongodb/mongo-install-connect

> Get MongoDB running locally and connect with the shell.

## Install Community Edition

Free, open-source, and available for every major OS.

```bash
# macOS (Homebrew)
brew tap mongodb/brew
brew install mongodb-community

# Ubuntu: follow MongoDB's apt repo instructions
# Windows: use the official .msi installer
```

## Start the server

`mongod` is the database server process — it listens on port 27017 by default.

```bash
brew services start mongodb-community
# or run directly:
mongod --dbpath /data/db
```

## Connect with mongosh

`mongosh` is the modern interactive shell for running commands against MongoDB.

```bash
mongosh
# connects to mongodb://127.0.0.1:27017 by default
```

Output:

```
Current Mongosh Log ID: ...
Connecting to: mongodb://127.0.0.1:27017/
test>
```

## MongoDB Compass

**Compass** is the official GUI — browse databases, run queries, and inspect indexes visually instead of typing everything.
