How to install a HEAT Node mining server

Hello,

I will show you how to install a Heat Node mining server in a few minutes in this article.

More info about Heat : http://heatledger.com/

Before we start :

1. Order a VPS, for example at ovh.com, Ubuntu 64 bits.
2. Create an account at heatwallet.com and write down your account number and passphrase.
3. Open your terminal on your computer to enter command lines.

1. In the terminal enter

ssh [email protected]
then enter the root password when asked

2. Packages and updates

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install default-jdk
sudo apt-get install unzip
sudo apt-get install curl

3. Get the app and go inside the app folder (Get the lastest version, now it's 1.0.1)

Check for new releases : https://github.com/Heat-Ledger-Ltd/heatledger/releases

wget https://github.com/Heat-Ledger-Ltd/heatledger/releases/download/v1.0.1/heatledger-1.0.1.zip

unzip heatledger-1.0.1.zip
cd heatledger-1.0.1

4. Edit the conf file

vi conf/heat-default.properties

Press I to go in insert mode and change these fields

heat.apiKey=something (Change this by anything)
heat.myAddress=Public IP address
heat.myPlatform= (Your Heat account number, create an account at heatwallet.com)
heat.maxNumberOfConnectedPublicPeers=500
heat.myHallmark=Your Hallmark generated from https://heatwallet.com/api/#!/Tools/encode (you will need your secret passphrase to generate your Hallmark and the IP of your server)

Press ESC once it's edited
Enter :w to save
Enter :q to quite

5. Start the blockchain

screen -mS heatledger bin/heatledger

Wait for full sync with the blockchain.
Once you have downloaded the lastest block from this page https://heatwallet.com/#/explorer you can start forging.

You can also check that your node is online at https://heatwallet.com/nodes.cgi (it might take a few minutes before it shows)

6. Launch forging

Open a new tab in the terminal (Cmd+T on Mac).
Log in again in your server if you are not logged in (step 1).
Go inside the heat folder by using cd heatledger-1.0.1

Replace YOURAPIKEY by your ApiKey then enter this command :
read -s KEY ; curl -k -s "http://localhost:7733/api/v1/mining/start/${KEY// /%20}?api_key=YOURAPIKEY" ; unset KEY

Enter your passphrase and then the enter button.

If you see something like {"deadline":55985,"hitTime":110535218} it's forging.

You are done.

Tips :

If you close the window and want to come back, just log in in the server again (step 1) and type screen -r, if the window doesn't show directly type screen -r ID (example : screen -r 2230) the ID can be found by typing screen -r.

Check on https://heatwallet.com/nodes.cgi that your node is running.
You can check your rewards at https://heatbrowser.com/report.html
