ETH RPC node on Sepolia network

HTTP request will be available on: http://<YOUR_IP>:8545

WS request will be available on: ws://<YOUR_IP>:8546

Monitoring will be available without credentials on: http://<YOUR_IP>:3000

Grafana has 3 dashboard: geth dashboard and sepolia dashboard (last simple all-in)

RECOMMENDATION: configure please your firewall rules (block all income to port 8545,8546,8086,3000 and use whitelist to access to your rpc, more about that can be found: https://github.com/chaifeng/ufw-docker)

Following parameters:

• 4-CPU
• 8-GBRAM
• 1-Tb nvmeSSD

First Step

• Update packages

  sudo apt update && sudo apt upgrade -y
  

• Install dependencies

  sudo apt install curl build-essential git wget jq make gcc tmux -y
  

• Install docker and docker compose

  curl -fsSL https://get.docker.com -o get-docker.sh
  sudo sh ./get-docker.sh
  docker version && docker compose version
  

• Run Docker as a non-root user

  sudo usermod -aG docker <your_user>
  

Relogin to your server to take effect from usermod !!!

Second Step

• Clone this repo to your server, navigate to goerli-rpc folder and spin up all docker containers

  git clone https://github.com/andrii1890/sepolia-rpc.git
  cd sepolia-rpc
  docker compose up -d
  

Third step

• Add alias for docker logs

  echo "#Sepolia Alias" >> $HOME/.profile
  echo 'alias geth_log="docker logs sepolia-rpc-geth-1 -f"' >> $HOME/.profile
  echo 'alias prysm_log="docker logs sepolia-rpc-prysm-1 -f"' >> $HOME/.profile
  echo 'alias influxdb_log="docker logs sepolia-rpc-influxdb-1 -f"' >> $HOME/.profile
  echo 'alias prometheus_log="docker logs sepolia-rpc-prometheus-1 -f"' >> $HOME/.profile
  echo 'alias grafana_log="docker logs sepolia-rpc-grafana-1 -f"' >> $HOME/.profile
  echo 'alias sepolia_log="cd $HOME/sepolia-rpc/ && docker compose logs -f"' >> $HOME/.profile
  source $HOME/.profile
  

  now you can simply find logs: geth_log, lighthouse_log, influxdb_log, prometheus_log, grafana_log, and all-in sepolia_log

Also you can find your geth and lighthouse logs in Goerli Dashboard

Understanding Geth's Dashboard https://geth.ethereum.org/docs/monitoring/understanding-dashboards

If Geth Dashboard doesn't work

Go to: CONFIGURATION > Data Sources > InfluxDB > Scroll to InfluxDB Details and find Database (it wiil be clear) write: geth > Save & test

If you want to enable password entry, just delete previous grafana folder and modify grafana.ini

cd ~/sepolia-rpc/data/ && sudo rm -rf grafana

cat /dev/null > ~/sepolia-rpc/grafana/grafana.ini && nano ~/sepolia-rpc/grafana/grafana.ini

and paste this

[auth.anonymous]
enabled = false
org_role = Admin

# specify role for unauthenticated users
# org_role = Viewer

[auth.basic]
enabled = true

[security]
# disable creation of admin user on first start of grafana
disable_initial_admin_creation = false

# default admin user, created on startup
admin_user = admin

# default admin password, can be changed before first start of grafana,  or in profile settings
admin_password = admin

# used for signing
secret_key = SW2YcwTIb9zpOOhoPsMm

# current key provider used for envelope encryption, default to static value specified by secret_key
encryption_provider = secretKey.v1

You are free to make any changes in docker-compose.yml if you know what you do 😉
