Run a Testnet read node

Table of Contents

Requirements #

  • Minimum hardware requirements: AWS EC2 m5.large with 8GB RAM, 2 vCPUs and at least 300GB of Amazon EBS General Purpose SSD (gp2) storage (or equivalent).
  • We would recommend going with Ubuntu Server 20.04 LTS (64-bit).

Network Settings #

Open up port 22 for SSH, as well as port 7946 for both TCP and UDP traffic. A custom port can be used with “–port <port>” flag when run your opera node.

Install Required Tools #

You are still logged in as the new user via SSH. Now we are going to install Go and Photon.
First, install the required build tools:

# Install build-essential
(validator)$ sudo apt-get install -y build-essential

Install Go #

# Install go
(validator)$ wget https://dl.google.com/go/go1.15.10.linux-amd64.tar.gz
(validator)$ sudo tar -xvf go1.15.10.linux-amd64.tar.gz
(validator)$ sudo mv go /usr/local

Export the required Go paths:

# Export go paths
$ vi ~/.bash_aliases
# Append the following lines
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

Validate your Go installation #

Install Photon #

# Install Photon
(validator)$ git clone https://github.com/TechPay-io/go-photon.git
(validator)$ cd go-photon/
(validator)$ make

Validate your Photon installation:

$./build/photon version

VERSION:
1.0.2-rc.5

Download genesis file #

Start the Photon read-only node using old genesis file ‘testnet.g’.

# Start opera node
(validator)$ cd build/
(validator)$ wget https://photon.techpay.io/testnet.g
(validator)$ nohup ./opera --genesis testnet.g --nousb &

You can start a node with a syncmode flag. There are two possible options “–syncmode snap” and “–syncmode full”. The default is full syncmode.

For archive node and validator node, you should use full syncmode.
