Setup Steps

Step 0. Run on local machine or create virtual machine instance on GCP.

On GCP create the following specs:

N1 Series, 1 cpu 3.5gb ram, Ubuntu 20.0

Create instance and first run command:
_{sudo apt-get update}

followed with upgrade command:
_{sudo apt-get upgrade -y}

Download developer essentials:
_{sudo apt-get install build-essential}

Download and setup OS firewall UFW
_{sudo apt-get install ufw
sudo ufw allow 6688
sudo ufw allow 6689
sudo ufw allow 22
sudo ufw enable (disrupt connections? YES. Will not disconnect)
sudo ufw status (confirm running and ports open)}

Download and install nano text editior (optional)
_{sudo apt-get install nano}

Install NMAP port monitoring tool (optional)
_{sudo apt-get install nmap
sudo apt-get update
sudo apt-get upgrade -y}

Download and install Yarn Debian/Ubuntu
_{https://classic.yarnpkg.com/en/docs/install/#debian-stable}
Enter following commands:
<sub>curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -

echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list</sub>

Once repository is configure you can run install command:
_{sudo apt update && sudo apt install yarn}

Add Yarn to your path with command:

_{cd /home/$USER
sudo nano .profile}

Paste the following line at the bottom of code.

_{export PATH="$PATH:`yarn global bin`"
sudo apt update}

Check Yarn Version with command:
_{yarn –version}

Download and setup Docker Container framework:
_{curl -sSL https://get.docker.com/ | sh
sudo usermod -aG docker $USER
exit
log in again}

Step 2. Create a directory

_{sudo mkdir ~/.chainlink-conflux}


Step 4. Setup postgresql database server
4a. On GCP go to >SQL and create a new PostgreSQL server with private ip address. (Public IP address will require a firewall rule to allow port 5432 access)
4b. Create a new database, new user and note down all database info for next step.
4c. Under “connections” section be sure to give your instance permission to the database.

Step 4. Create an .environment file
Example .env:

** No ETH RPC is required when running Chainlink node on Conflux network!

** For this specific experiment we will be using a Infura Kovan ETH RPC.

*Before configuring the Chainlink components, there needs to be an oracle contract on the Conflux Network that emits events.

Deploy test contract on Conflux testnet network

This is needed for the EI to trigger job runs on the Chainlink node. See the contractInteraction folder for code to interact with the Conflux Network.

Step 5. Run Chainlink Docker run command:

_{docker run –name chainlink-conflux -p 6688:6688 -v ~/.chainlink-conflux:/chainlink -it –env-file=.env smartcontract/chainlink local n}


5a. Create your node wallet password
5b. Create dashboard login credentials. Enter email address and password.

*node will begin sync and logging info. Press ctrl+p ctrl+q to exit. Use command _{sudo docker ps} and confirm container is running.
