Official Docs https://docs.arbitrum.io/node-running/how-tos/running-an-archive-node

Pre-requisites

Update, upgrade, and clean the system, and then firewall management (ufw), Docker, and the Git version control system.

sudo apt update -y && sudo apt upgrade -y && sudo apt auto-remove -y
sudo apt install docker.io docker-compose git ufw -y

Set explicit default UFW rules

sudo ufw default deny incoming
sudo ufw default allow outgoing

Allow SSH, HTTP and HTTPS

sudo ufw allow 22/tcp
sudo ufw allow 80
sudo ufw allow 443

Get the IP address of the host machine, you can use the following command in a terminal or command prompt

curl ifconfig.me

Set an A record for a domain, you need to access the domain's DNS settings and create an A record that points to the IP address of the host machine. This configuration allows users to reach your domain by resolving the domain name to the specific IP address associated with your host machine.

Create Arbitrum directory

The first command, mkdir arbitrum, will create a new directory named arbitrum in the current location. The second command, cd arbitrum, will change your current working directory to the newly created arbitrum directory. Now you are inside the arbitrum directory and can start storing docker-compose and related files in it.

mkdir arbitrum
cd arbitrum

Create .env file

sudo nano .env

Paste the following into the file.

EMAIL={YOUR_EMAIL} #Your email to receive SSL renewal emails
DOMAIN={YOUR_DOMAIN} #Domain of your reth node you set earlier, reth.indexerdao.com
WHITELIST={YOUR_REMOTE_MACHINE_IP} # Remote IP's allowed to connect to RPC
ARBITRUM_L1_URL={YOUR_L1_RPC} #RPC endpoint of Ethereum L1 RPC

{% hint style="info" %} ctrl + x and y to save file {% endhint %}

Create docker-compose.yml

sudo nano docker-compose.yml

Paste the following into the docker-compose.yml

version: '3.8'

x-logging:
  &default-logging
  options:
    max-file: '1'
    compress: 'false'
  driver: local

In this step, we will create a helpful script named arbitrum-classic-entrypoint.sh to automatically download the initial snapshot for your Arbitrum Classic node when it starts for the first time.

sudo nano arbitrum-classic-entrypoint.sh

Paste the following into the file.

#!/bin/bash

if [ -f /root/.arbitrum/mainnet/INITIALIZED ]; then
    echo "The data directory has already been initialized."
else
    echo "lemme download the database quickly"
    rm -rf /root/.arbitrum/mainnet/db
    curl https://snapshot.arbitrum.foundation/arb1/classic-archive.tar | tar -xv -C /root/.arbitrum/mainnet/ && touch /root/.arbitrum/mainnet/INITIALIZED    
fi

echo "LFG!!!"

/home/user/go/bin/arb-node $@

Run Arbitrum Node

docker-compose up -d

Monitor Logs

Use docker logs to monitor your nitro and classic nodes. The -f flag ensures you are following the log output

docker logs nitro -f
docker logs classic -f

Test Arbitrum RPC 🧪

curl --data '{"method":"eth_syncing","params":[],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST https://{DOMAIN}
