MongoDB on Linux Mint

MongoDB is an open-source cross-platform NoSQL database solution. As it’s a NoSQL database, it’s free from the restricted nature of the traditional databases (for example, MySQL), offering more flexibility for storing data. MongoDB can also be treated as a file storage solution! MongoDB offers efficient scaling, thanks to its shading feature.

There are two editions of MongoDB available to the customers – the Community and Enterprise version. Now, for general users, the MongoDB Community edition will be enough for testing/developing purposes. However, for large-scale implementation, it’s a good idea to get the Enterprise one. MongoDB Enterprise comes with additional features like customer support, Kubernetes integration, faster memory performance, certification, etc. Check out MongoDB Enterprise Advanced.

In this article, however, I’ll be showcasing how to install and use the MongoDB Community edition.

Install MongoDB on Linux Mint

There are multiple ways we can install MongoDB. Because of its popularity, it’s already a part of the Ubuntu package servers. Linux Mint, being an Ubuntu derivative, can directly grab MongoDB from the package server. However, the official recommendation of MongoDB is to use its own repository for installing the database software.

Ready? Let’s jump right into it!

Install MongoDB from Ubuntu package server

MongoDB is directly available from the Ubuntu package server. All you need is to tell APT to grab and install the mongodb package. Although it’ll work just fine, according to official MongoDB documentation, it’s not recommended method. Follow it at your own responsibility.

First, fire up a terminal and update the APT cache.

Now, tell APT to install MongoDB.

Install MongoDB from MongoDB repo

MongoDB officially offers repo for Ubuntu, Debian, SUSE Linux, and Amazon. MongoDB officially recommends this method of installing MongoDB. This makes sure that you’re always using the latest version. Linux Mint is Ubuntu-based, so the Ubuntu repo will work just fine.

Note: The repo is version-dependent. This method will showcase the installation of the current latest MongoDB stable version (MongoDB 4.2). For other versions, check out the MongoDB installation document.

Fire up a terminal and start running the following commands. First, let’s check out if GnuPG is installed. GnuPG comes preinstalled with Linux Mint. However, if it was uninstalled previously, then this command will install it right away.

Now, add the public GPG key of MongoDB repo.

APT is ready to communicate with the MongoDB repo. Add the MongoDB repo in the list of APT package servers.

Update the APT cache.

The MongoDB repo is added successfully. Now, tell APT to install MongoDB. The package name is mongodb-org. Note that mongodb is from Ubuntu repo whereas mongodb-org is from MongoDB repo.

Using MongoDB

Once the installation is complete, let’s make sure that MongoDB is running. Run this command in the terminal.

The command threw some error. It’s because MongoDB, by default, doesn’t start with boot. To fix this, run the next two command. Essentially, we’re telling systemctl to start and enable MongoDB service at boot.

Check MongoDB once again.

Voila! MongoDB is running perfectly! It’s the MongoDB shell that’s running. It serves as the MongoDB control center. MongoDB has its own commands and functions. The following command will print a shortlist of available commands and functions.

Final thoughts

MongoDB is a powerful database software. It’s even incorporated by Google, Facebook, PayPal, EA, Adobe, eBay etc. giants. Check out companies using MongoDB. That, by itself, is a testimony of the power of MongoDB.

This article just discusses how to install MongoDB. There is a lot to learn about it. You can find plenty of tutorials on the internet on getting started with MongoDB. Check out beginner’s guide to MongoDB.

The Tesla Cybertruck is finally a reality. OK, so not quite, but we know there’s at least one of them in the world. But Elon Musk is promising to deliver this unconventional all-electric full-size truck surprisingly soon, and the company is already taking reservations. Whether you’re actually interested in parking one of these iconoclastic, triangle-shaped pickups in your driveway, or you’re just curious as to how the order process, here’s what you need to know.

Like the order process for the Model Y crossover SUV, which isn’t in production yet, navigating the reservation system is dead simple and only takes a couple of minutes. First, you click over to Tesla’s Cybertruck microsite, where you’ll be presented with three choices:

• Single-motor, rear-wheel drive: $39,900
• Dual-motor, all-wheel drive: $49,900
• Tri-motor, all-wheel drive: $69,900

Tesla hasn’t yet detailed battery sizes, but during the presentation, a max-range figure of over 500 miles was disclosed for the tri-motor model, while the dual-motor version was listed at 300-plus miles and the single-motor base model at a still-healthy 250-plus miles.

For now, the only Cybertruck option listed is Self-Driving, priced at a heady $7,000. As the site notes, “Selecting Full-Self Driving today will secure your price as it increases in the future.” (Despite the option title and Musk’s bold claims for the tech, clicking on the “Learn more” button reveals a lengthy disclaimer that says the tech’s current version requires supervision and does not enable autonomy.)

Still onboard? You’ll have to plunk down your name, email address, phone number, credit card number and agree to pay a $100 deposit. The funds will be taken immediately, but Tesla says the deposit is fully refundable. Note: By placing the order, you’re consenting to allow Tesla to save your credit card. 

By clicking “Place Order,” you also agree to Tesla’s Cybertruck Agreement, Supercharger Fair Use Agreement, and Customer Privacy Agreement, which is all fairly boilerplate stuff that should be familiar to Tesla customers. The salient points in the first document are that your vehicle’s configuration “will be confirmed with you at a later date,” including Tesla providing the “Final Price Sheet” as one’s delivery date looms.

Tesla’s website says you can cancel a Cybertruck preorder at any time right up until delivery, at which point reservation holders are entitled to a full refund of their preorder payments. 

“Until your final configuration is matched to a vehicle, you may make changes to your Vehicle Configuration,” Tesla says. In other words, if you’re curious about the Tesla Cybertruck but you’re not sure how you want to configure yours (or maybe you’re not even sure if you want one, but think you might be interested with more time and research), there doesn’t seem to be much of a downside to plunking down a Benjamin to hedge your bets and get on the waiting list. After all, Tesla says you’re entitled to get your deposit money back right up until delivery.

Speaking of delivery, when can you expect your Tesla Cybertruck? According to the Silicon Valley automaker’s website, “you will be able to complete your configuration as production nears in late 2021.” However, if you want the most expensive — and presumably the most powerful — tri-motor, all-wheel-drive Cybertruck, you’re looking at an estimated production date of late 2022. Take all of this with several grains of salt (perhaps a whole shaker), of course. Elon Musk’s team doesn’t exactly have a sterling record of sticking to announced timeframes, though they do seem to be getting better about doing so.

It is not immediately clear where Tesla plans to build the Cybertruck, which other colors it might be available in (stainless steel is notoriously hard to paint) or which other options will be available. 

Despite showing an electric ATV during the Cybertruck reveal as a special “one more thing” surprise, Tesla hasn’t indicated whether it will produce the recreational vehicle or whether it will offer preorders.

Once you’ve completed your Cybertruck order, you’ll receive a confirmation screen with a tracking number and an adorable little owl. Voila! You’re all set. Now all you have to do is wait…

Future-proof your database with one of these awesome cloud providers

Databases are just as an important part of cloud services as with normal IT operations. However, there are a variety of different ways that data can be stored for different database types, and the chances are that you’ll need to account for multiple versions.

If you’re using cloud management software or a cloud broker service then it’s likely that you’re drawing on multiple cloud platforms, which means it’s important to be able to store your data in the type of database you need for queries.

Traditionally the most common form of database was a relational one, as used in Microsoft Access and it’s more powerful big brother, MySQL. In these sort of databases there is a direct relationship between the different points of data, arrange in columns and rows.

However, these days non-relational databases have become more common, in which data is stored without explicit structure and mechanisms to link it. These have become more in demand for business intelligence tools and cloud analytics, which seek to connect underlying trends which might be otherwise hidden. This might be done by querying existing databases or even unstructured data found in data lakes.

Whichever types of database you need, most providers offer the choice of different database formats to use as required. Here we’ll look at the best of them.
