Run a Testnet read node

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 Opera.
First, install the required build tools:
# Install build-essential
(validator)$ sudo apt-get install -y build-essential
# Install go
(validator)$ wget https://dl.google.com/go/go1.17.7.linux-amd64.tar.gz
(validator)$ sudo tar -xvf go1.17.7.linux-amd64.tar.gz
(validator)$ sudo mv go /usr/local
# Export go paths
(validator)$ vi ~/.bash_aliases
# Append the following lines
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH
#
source ~/.bash_aliases
Run a read node
You can run your read node using go-opera 1.1.1-rc.2 (full sync or snap sync mode).
# Install Opera
(validator)$ git clone https://github.com/Fantom-foundation/go-opera.git
(validator)$ cd go-opera/
(validator)$ git checkout release/1.1.1-rc.2
(validator)$ make
Validate your Opera installation:
$./build/opera help
​
VERSION:
1.1.1-rc.2
Download a genesis file from this list of genesis files. 
# Start opera node
(validator)$ cd build/
(validator)$ wget https://download.fantom.network/testnet-6226-no-mpt.g
(validator)$ nohup ./opera --genesis testnet-6226-no-mpt.g --nousb &
You can start a node with a syncmode flag. There are two possible options:
 "--syncmode snap", and
"--syncmode full" (by default).
For archive node and validator node, you should use full syncmode.
