The NEM team would like to thank Malek for contributing this blog.
This guide will cover the basic setup of an Amazon AWS account including sign up, creation and configuration of an EC2 instance.
Note: This article follows the basic structure of the Guide How to Setup an Azure account for a NEM Supernode written by Patrick. It would also be useful to familiarize yourself with the original tutorial and forum topic on how to set up a Supernode, or the other tutorials on how to configure a regular node on Windows, Mac, or Ubuntu.
To create an Amazon AWS account, you need:
– e-mail address
– credit card
– phone number
To follow this guide, you will need these additional software downloads.
– putty.exe for SSH connection
– puttygen.exe to create keys for login
– pageant.exe to load the created keys
Before we start with Amazon AWS, let’s create our login keys with puttygen.exe.
1. Start puttygen.exe. Choose RSA and 2048 bits from the bottom.
2. Click on “Generate”
3. Choose a “Key comment” (for example: name of your node)
4. Choose a “Key passphrase” and confirm it
5. Save the public key & private key files
6. Close puttygen
Open the Amazon AWS signup website and click “Create an AWS Account”.
Choose “I am a new user,” and enter your e-mail address.
Type your e-mail address again and enter your password.
Enter your contact information and agree to the terms of service.
Enter your payment information.
Enter the security check characters and your telephone number. After pressing the button “call me now” you will see a code and receive a phone call. Enter this code on your telephone’s keyboard.
After entering the right code, you will see this screen.
Select a support plan. For expample “basic”.
Before logging in the first time, wait until the “Welcome to Amazon Web Services” email arrives.
First log in
Click on the link “Getting Started Resources” in the email you received.
You can also use this link https://console.aws.amazon.com/
Click on “Sign in to the Console”.
Enter your email and password.
Importing a Public Key
Select “EC2” in the “AWS Services” box.
Select “Key Pairs” in the “Network & Security” Section.
Select “Import Key Pair”.
Select your public key file (created in the begin of this guide with puttygen).
Define a key pair name and press “Import”.
Launch an EC2 Instance
Move to the “EC2 Dashboard” and press “Launch Instance”.
Go to “AWS Marketplace”, search for “Debian” and select it from the list.
Choose “Debian GNU/Linux 8 (Jessie)” and click create.
Choose an instance type. For operating a Supernode, we recommend using at least a “t2.small” instance. To continue, click on “configure instance details”.
Use the default settings and click on “add storage.”
Use the default settings and click on “add tags”.
Click to “add a name tag”.
Enter your desired server name in the value column. E.g. “Supernode”
To go on click “Configure Security Group”
Add the following rules:
Type: Custom TCP, Port Range: 7890, Source: Anywhere (for NIS)
Type: Custom TCP; Port Range 7880, Source: Anywhere (for servant)
Type: Custom TCP, Port Range 7778, Source: Anywhere (for light wallets)
Notice: For security reasons, you may restrict SSH access by entering your IP-address instead of 0.0.0.0/0 in the first row.
Now select the key pair you have uploaded in the “importing a public key” section of this guide and click on the checkbox to acknowledge that you have access to the private key file (you already created the private key in puttygen in the first section of this guide). Finally, click on “Launch Instance”!
After launching, you will see a screen indicating the launch status. Click on “View Instances”.
Write down the Public DNS. E.g. ec2-XX-XX-X-XXX.us-east-2.compute.amazonaws.com
Connecting to your new EC2 Instance
After setting up the instance, we will try to connect to our server.
Start pageant.exe and open “View Keys” from the tray icon.
Click on “Add Key” and select your saved private key (.ppk) you created earlier with puttygen. After the key is loaded, you can minimize pageant to tray (but don’t shut it down, it needs to run in the background).
Start putty and navigate to “Connection – SSH – Auth”. Browse for your private key file (.ppk).
Navigate to “Connection – Data” and input “admin” in the auto-login username field.
Go to “Session” and enter your instance Public DNS (E.g. ec2-XX-XX-X-XXX.us-east-2.compute.amazonaws.com, not your instance IP-address) in the “host name” field. Save the session (optional) and click “Open”.
A console will open. A username and password are not needed, it will automatically load your username from putty and your key from pageant!
By default, the user root is deactivated. To activate, log in as a standard user.
Type the following in the console:
sudo su -
Set a root password with:
After setting a password, the root user is activated. To login to your EC2 instance you will still need the standard user (with RSA-key login), but as soon as you are logged in, you can change to root with:
The EC2 instance is now ready for installation.
For the Installation, we will use Paul’s guide (click here), since it has covered everything.
There is one value which you have to change: From section 1.3 change:
Java -Xms768M -Xmx768M
Java -Xms1024M -Xmx1024M
Other than that you can follow the guide, and your supernode will be set up correctly!
