Running Your Own Monero Node

Running your own Monero node enhances privacy, supports the network, and allows you to verify transactions independently.

Warning: Syncing the Monero blockchain requires significant resources: ~100 GB disk space (pruned), and a stable internet connection. Initial sync may take days, but with NVMe drives it takes around a day. Exposing RPC publicly (as in this script below) requires strong authentication—use a secure password within the script and consider firewall rules.

Steps to Set Up and Prepare OS (Debian in my case): Download and Extract Monero CLI:

Go to https://www.getmonero.org/downloads/ and copy link for the Linux CLI package (e.g., monero-linux-x64-v0.x.x.x.tar.bz2).

 bash
    
wget https//.... # download via cli
mkdir -p ~/monero
tar -xvf monero-linux-x64-v0.x.x.x.tar.bz2 -C ~/monero

This places monerod in ~/monero/monerod. Make it executable: 

 bash
    
chmod +x ~/monero/monerod

Save the following modified script as run_monero_node.sh in your home directory (or anywhere convenient).

READ THE SCRIPT CAREFULLY

 bash
    
#!/bin/bash
set -euo pipefail

# --- Configuration ---
# Base directory for Monero files (adjust if needed)
MONERO_BASE_DATA_DIR="${HOME}/monero"
MONERO_DATA_DIR="${MONERO_BASE_DATA_DIR}/.bitmonero"
MONERO_BIN="${MONERO_BASE_DATA_DIR}/monerod"  # Path to the monerod binary

# RPC credentials, used in wallets (CHANGE THESE to secure values!)
RPC_USER="your_rpc_username"  # e.g., "monero_user"
RPC_PASS="your_strong_password"  # Use a long, random password

# Create data directory if it doesn't exist
mkdir -p "${MONERO_DATA_DIR}"

# Check if monerod binary exists
if [ ! -f "${MONERO_BIN}" ]; then
    echo "Error: The Monero binary could not be located at: ${MONERO_BIN}"
    echo "Please download the Monero CLI from getmonero.org, extract it to ${MONERO_BASE_DATA_DIR}, and try again."
    exit 1
fi

# Check if monerod is executable
if [ ! -x "${MONERO_BIN}" ]; then
    echo "Error: The Monero binary at ${MONERO_BIN} does not have execute permissions."
    echo "To fix this, run the command: chmod +x \"${MONERO_BIN}\" and then retry."
    exit 1
fi

# Command to run monerod with optimized settings
# - Pruned blockchain to save space (~1/3 full size)
# - RPC exposed on all interfaces (0.0.0.0) with auth—secure your firewall!
# - Priority nodes for faster sync
# - ZMQ for tools like P2Pool
# - In/out peers tuned for performance
MONEROD_COMMAND=(
    "${MONERO_BIN}"
    --data-dir "${MONERO_DATA_DIR}"
    --rpc-login "${RPC_USER}:${RPC_PASS}"
    --rpc-restricted-bind-ip=0.0.0.0
    --rpc-restricted-bind-port=18089
    --add-priority-node=p2pmd.xmrvsbeast.com:18080
    --add-priority-node=nodes.hashvault.pro:18080
    --disable-dns-checkpoints
    --confirm-external-bind
    --enable-dns-blocklist
    --check-updates=disabled
    --no-igd  # Disable UPnP port mapping
    --in-peers=64
    --out-peers=32
    --zmq-pub="tcp://127.0.0.1:18084"  # For P2Pool integration
    --prune-blockchain
    # Notes:
    # - Default P2P port: 18080 (firewall: allow inbound if public)
    # - Default unrestricted RPC port: 18081 (not used here)
)

# Run the command
exec "${MONEROD_COMMAND[@]}"

If you planning to use p2pool, use it on the same server, --zmq-pub="tcp://127.0.0.1:18084" only exposes the port on locahost.

Make the Script Executable:

 bash
    
chmod +x run_monero_node.sh

To run in background: Use screen, tmux, or nohup ./run_monero_node.sh &.

Secure Your Server with UFW

 bash
    
sudo apt update
sudo apt install ufw

Deny all incoming traffic by default (blocks everything unless explicitly allowed) and allow all outgoing traffic (your node needs to connect out to peers): 

 bash
    
sudo ufw default deny incoming
sudo ufw default allow outgoing

Allow ssh port (22) and any other port you plan to use:

 bash
    
sudo ufw allow 22/tcp
sudo ufw allow 18080/tcp # recommended to contribute to the Monero network
sudo ufw allow 18089/tcp # Optionally allow restricted RPC (port 18089) if you need remote access
 
# enable firewall:
sudo ufw enable
sudo ufw status verbose

If you have RPC enabled now you can also connect wallets by pointing to http://your_server_ip:18089 with RPC credentials.

NOTE: If you want to host the node on a remote server I recommend to use Datalix servers, they offer top ups via Monero!

I'm on Boost package ( 6.95 € Monthly ) and works perfectly on pruned node, they use nvme drives: https://datalix.eu/a/monerotown
