Machine

This installation uses the AWS i3.xlarge instance because it has a solid state hard drive which is large enough

  • i3.xlarge ($0.374 per Hour)
  • 1 x 950 NVMe SSD Storage
  • 4 CPU
  • 30.5 GB RAM

Software (OS)

sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get install -y build-essential

Auxillary hardware

View NVMe volume (which is not yet mounted/mapped/formatted)

lsblk

There is a ~300Gb drive with the name of nvme0n1

nvme0n1     259:2    0 279.4G  0 disk

Create a file system

sudo mkfs -t ext4 /dev/nvme0n1

Part of the output from the above mkfs command will include the Filesystem UUID. Cut and paste this UUID because it will be used in an upcoming command.

Filesystem UUID: 6f6177fe-947a-46a2-b593-c36dfaaa8407

Create an easily accesible mount point on the main drive (where the operating system runs) and then set the permissions of this mount point to the ubuntu user.

sudo mkdir /media/nvme
sudo chown -R ubuntu:ubuntu /media/nvme/

Ensure that this drive is mounted each time the system is restarted. Add this line to the /etc/fstab file (remember the UUID from the previous step?).

UUID=6f6177fe-947a-46a2-b593-c36dfaaa8407 /media/nvme ext4 defaults 0 0

Once the above commands have succeeded, reboot the instance.

sudo shutdown -r now

After the reboot, see the mounted ~300Gb NVMe SSD using the df command

df -h
/dev/nvme0n1    275G   65M  260G   1% /media/nvme
#ensure that the /media/nvme directory is owned by ubuntu by typing ls -la /media/nvme If it is not then type the following command
sudo chown -R ubuntu:ubuntu /media/nvme/

Create directory for Ethereum data

mkdir /media/nvme/ethereum_data

Software (Ethereum)

Install Ethereum

sudo apt-get install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install ethereum

Start Ethereum full node - in current terminal

geth --datadir "/media/nvme/ethereum_data" --maxpeers=50 --syncmode "full" --rpc --rpcport "8545" --rpcaddr "0.0.0.0" --rpccorsdomain "*" --cache 4096

Or to be able to start Ethereum full node and log out of console with Geth still running use the following twist on the above command

nohup geth --datadir "/media/nvme/ethereum_data" --maxpeers=50 --syncmode "full" --rpc --rpcport "8545" --rpcaddr "0.0.0.0" --rpccorsdomain "*" --cache 4096 >/dev/null 2>&1 &

Ensure that port 8545 is only visible to the smart contract search engine IP

Connect to geth console

geth attach ipc:/media/nvme/ethereum_data/geth.ipc
