1.1.3 - This plan (below) matches our recommended system requirements
1.1.4 - Leave the additional features section blank. This guide will not use any startup scripts. So leave that option alone as well.
*OPTIONAL: You can choose to set up an SSH key to make it easier to securely log into your server. Click add new and follow the tutorial for creating an SSH key. This step is optional, but recommended. Using an SSH key to login is not only easier than using a password, but much more secure.*
1.1.5 - Enter a hostname and label (example: stakingNRG) for your server and click Deploy Now
1.1.6 - Wait for your server to install. It should only take a few minutes.
You will receive an email confirming that your server has been created, with information on how to access it remotely.
2. - Login to your VPS
You can either open the console within Vultr or use any SSH (secure shell) software to connect to the VPS. If you’re using Windows, we recommend PuTTY.
2.1.1 - For Mac & Linux
Both ssh and sftp already come with the system to login and securely transfer files respectively. Open a Terminal and run this command:
ssh user@[server ip address]
Example:
ssh root@144.202.73.194
2.1.2 - For Windows
In Putty, enter your server’s IP address, make sure SSH and Port 22 are selected and then click on Open.
2.2 - You may get a security alert about the server’s rsa2 key fingerprint. Just click Yes to trust the server and connect via SSH.
2.3 - You will be prompted to enter your username and password. See the informations on your Vultr dashboard.
You are now connected to your VPS!
2.4 - We HIGHLY recommend you to change your password by running the command:
passwd
3. Run Provisioning Script
Follow the instructions in Install Energi Core Node on Linux VPS to install and setup Energi Core Node on the VPS.
Next Step - Staking & Masternode
Before setting up Staking node / Masternode, bootstrap the node. This will expedite the sync process.
Now that you are all set with Energi Core Node, you can either follow the Staking or the Masternode Guide :
