## Introduction

The goal here is to be able to run the below command in your local terminal.

```
terraform -help
```

## Download Binary from HashiCorp

After downloading the binary for macOS (for instance, after the download you should see **_terraform_1.4.6_darwin_amd64_**), once you unzip the binary you should see the terraform binary file.

## Install the HashiCorp Binary at macOS

If you're getting an error like **_"terraform" cannot be opened because the developer cannot be verified_**, you can try the below setting to avoid this error:

- System Preferences
- Security & Privacy
- Choose General

Once the terraform binary file is allowed on your local machine, run the below code in the terminal to include the **_terraform_** file in the path.

Type this to check the current **_PATH_**:

```
echo $PATH
```

Type this to move the terraform file to the user's PATH folder:

```
mv ~/Downloads/terraform /usr/local/bin/
```

Now, if you type the below command and it works, you should see a list of help commands.

```
terraform -help
```

## Conclusion

Installing Terraform on macOS is straightforward — download the binary from HashiCorp, allow it in your security settings, and move it to a directory in your PATH. You can then verify the installation by running `terraform -help`.

## Introduction

This blog shows how to set up MongoDB 4.4 Community version on macOS, create a
simple database, table, and collection, and how to backup and restore data by
using mongoexport and mongoimport.

## Install MongoDB Server

Installing MongoDB on Mac is a little different compared to Windows. You'll
need Homebrew to install MongoDB. This blog assumes Homebrew is already
installed on your Mac.

### Download Homebrew Formula for MongoDB

```
brew tap mongodb/brew
```

### Install MongoDB on macOS

```
brew install mongodb-community@4.4
```

## Install MongoDB Tools

Starting from MongoDB 4.4, using Homebrew will also install mongodump,
mongoexport, mongoimport, and some other command-line tools.

## Install MongoDB Compass

MongoDB Compass is the GUI tool. You should install it on your local
development environment so you can connect to the MongoDB server and run
queries from the GUI.

To install MongoDB Compass on macOS, go to the official site
here
to download the dmg file and install it on your macOS.

To connect to the localhost MongoDB instance, just enter the following URL in
the MongoDB Compass UI.

```
mongodb://localhost:27017
```

## Create Database, Collection, and Record

After you install MongoDB Compass and connect to the localhost MongoDB
instance, you should be able to easily create a new database, collection, and
record.

You could also use the command line or the MONGOSH BETA command line window in
the Compass UI.

### Create Database

```
show dbs
use myNewDatabase
```

First, **show dbs** will list all the databases. The
**use myNewDatabase** command will create a database, but you won't
see it until you add a new collection.

### Create Table and Record

```
db.myUser.insert({name: "john"});
```

This command will create a new table called myUser and insert a new record
into the collection.

## MongoDB Backup and Restore Data

At this point, you have the MongoDB server installed and can create databases
and collections. Next, I'd like to try backing up and restoring data by using
mongoexport and mongoimport. The mongoexport tool will export data from MongoDB
as a JSON file, and then mongoimport can import the JSON file into MongoDB.

This works well in a small development environment when you want to export a
set of data and then load it into another environment from a JSON file.

### Use Mongoexport to Export Data to JSON

First, navigate to the location that has the mongoexport executable file, then
run the following command.

```
mongoexport --collection=myUser --db=myDB --out=myUser.json
```

This command will look up the **myDB** database's **myUser**
collection, then output the entire result into a **myUser.json**
file.

### Use Mongoimport to Import Data to the Existing MongoDB Server

The following command will use **myUser.json** and then override
the myUser collection, using upsert mode so any existing matching records will
be replaced.

```
mongoimport --collection=myUser --db=myDB --file=myUser.json --mode=upsert
```

## Conclusion

That's how you can set up MongoDB on macOS, create databases and collections,
and back up and restore data using mongoexport and mongoimport. MongoDB
Compass is a very helpful GUI tool for managing your local MongoDB instance.
