Part 01: How order and configure your VPS server in 2 minutes

Before installing the node you need to rent a VPS server
The advantages of VPS are that they have high availability and are easy to configure.
Of course I’ll explain how to rent a VPS server at a lower cost and especially how to configure it in less than 2 minutes.

Let’s go…

Order your VPS on Contabo by clicking here.

To be completely transparent with you this is an affiliate link that you can use even if you already have an account on Contabo. Thank you in advance.

Select Cloud VPS M

1 month for the rental period, you can extend later if needed

Do not change anything for the geolocation of your VPS server

Select 400GB SSD for storage type

Select Ubuntu 20.04

Generate your passport and copy and paste it now into a notepad that will be saved on your computer

Don’t touch anything

Don’t touch anything and click on “NEXT”

If you are new to Contabo and you are an individual, do not touch anything

Fill in the fields with your personal data

Finish filling in the last fields with your personal information and click on Next button to proceed to payment

Once you have finished paying for your order. You will receive a first email.

Corresponding to the status of your order

And approximately 15 minutes later you will receive a second email with all the information to connect to your VPS.

The login details to connect on your VPS

Part 02: How to connect to your VPS

With MacOS:

MacOS includes already a SSH command. To connect via SSH from this operating system, first open the Terminal window. You can find this tool by going to “ Application->Utilities->Terminal”.

With Windows : I invite you to download Putty by clicking “here**” (**You can directly download the installation file with this link).

This is the file illustrated in the image above, if you wish to download another one click on this “link”

Now open the .exe file to start the installation of Putty and follow the instructions to complete the installation. At the end of the installation you will have a shortcut to Putty on your desktop.

Now launch Putty

Launch Putty, a new window will open in which you will enter the IP address of your VPS and click on Open

The interface of your server will open and will ask you for the login details.

Now you are finally on your server (see image below):

Tip 1: To paste any command that you have already copied above, just right-click where you want to paste the command

Tip 2: Only paste or write a command when your vps server allows it. As soon as “root@vmxxxxxxxxx: “is visible you can write otherwise you have to wait

In this example you have permission to write or paste a command

Now you are ready to get serious. You just have to paste one by one the commands that I put at your disposal below. Take your time and make sure you have taken the order from start to finish.
To help you I have put some screenshots showing the result you should get each time you paste a command.

Best of luck…
