What are the benefits of operating my own Monero node?
- Running your own Monero node gives you the independent capability to send, receive, and verify transactions, ensuring the utmost privacy and security.
- By not relying on others’ nodes to handle your transactions, you maintain a higher level of control and self-reliance.
- Operating your own node contributes to the decentralization of the Monero network, enhancing its overall resilience and security.
- To utilize a Monero wallet effectively, you need to connect to a fully synchronized node, and having your own node is the ideal choice.
- Connecting to the Monero network involves running a peer-to-peer application called monerod (with the “d” denoting daemon), which serves as the foundation of the Monero network.
- Additionally, you have the option to offer your node as a public remote note, volunteering your node as a public resource to assist in onboarding new Monero nodes and facilitating the relay of transactions for other Monero users.
There are two different types of Monero nodes available.
- Full Node: Stores all blockchain data
- Pruned Node: Stores a random 1/8th of the blockchain’s data and requires much less disk space
Minimum Full Node System Requirements
- Dual-core CPU
- 4+ GB RAM
- 160GB+ SSD HD
Minimum Pruned Node System Requirements
- Same as full node yet with a smaller HD
- 80GB+ SSD HD
1. Adjusting port settings and firewall configurations.
Suggestion: The most recommended choice is to set up a Public Full Node using port 18089, which includes a restricted RPC port. This option ensures optimal support for the Monero network while enabling both yourself and others to utilize it as a remote node for wallets. By following the instructions provided in this guide, you will successfully deploy a Monero node configured in this manner. If desired, you can modify the port settings to achieve a more limited functionality.
# By default, deny all incoming and outgoing traffic
sudo ufw default deny incoming
sudo ufw default allow outgoing
# Allow ssh access
sudo ufw allow ssh
# Allow monerod p2p port
sudo ufw allow 18080
# Allow monerod restricted RPC port
sudo ufw allow 18089
# Enable firewall
sudo ufw enable
# Verify status
sudo ufw status numbered
Setup service accounts.
# creates system user account for monero service
sudo adduser –system –group –no-create-home monero
Create some folders the service needs & set their ownership:
# logfile goes here
sudo mkdir /var/log/monero
# blockchain database goes here
sudo mkdir /var/lib/monero
# create file for config
# set permissions to service account
sudo chown -R monero:monero /var/lib/monero
sudo chown -R monero:monero /var/log/monero
Download the latest monero node binaries.
wget –content-disposition https://downloads.getmonero.org/cli/linux64
Verify the download hash signature.
#download latest hashes.txt file
#search hashes.txt file for the computed sha256sum
grep -e $(sha256sum monero-linux-x64-*.tar.bz2) hashes.txt
A match appears and this confirms the file is valid.
Extract tar and copy to /usr/local/bin
tar -xvf monero-linux-x64-*.tar.bz2
sudo mv monero-x86_64-linux-gnu-*/* /usr/local/bin
sudo chown -R monero:monero /usr/local/bin/monero*
rm -rf monero-x86_64-linux-gnu-*/
Configure your Monero Node with a config file.
sudo nano /var/lib/monero/monerod.conf
Add this to the file.
#blockchain data / log locations
max-log-file-size=0 # Prevent monerod from managing the log files; we want logrotate to take care of that
# P2P full node
p2p-bind-ip=0.0.0.0 # Bind to all interfaces (the default)
p2p-bind-port=18080 # Bind to default port
public-node=true # Advertises the RPC-restricted port over p2p peer lists
# rpc settings
# i2p settings
# node settings
db-sync-mode=safe # Slow but reliable db writes
enable-dns-blocklist=true # Block known-malicious nodes
no-igd=true # Disable UPnP port mapping
no-zmq=true # ZMQ configuration
# bandwidth settings
out-peers=32 # This will enable much faster sync and tx awareness; the default 8 is suboptimal nowadays
in-peers=32 # The default is unlimited; we prefer to put a cap on this
limit-rate-up=1048576 # 1048576 kB/s == 1GB/s; a raise from default 2048 kB/s; contribute more to p2p network
limit-rate-down=1048576 # 1048576 kB/s == 1GB/s; a raise from default 8192 kB/s; allow for faster initial sync
Configuration File Comments
falseif you want to store full blockchain
falseif you do not want other users to use your node.
rpc-restricted-bind-ip/port flagsenable restricted access to your node but allow full RPC from other Monero wallets on your LAN.
- Limit the upload speed in case you have a data cap:
limit-rate-up=8192(in kB/s). Conversely, if you have an unlimited data plan, consider increasing the upload speeds to better support the Monero network. A node can typically use up to 1TB traffic per month.
monerod.service systemd unit file. Simply copy and paste.
cat > $HOME/monerod.service << EOF
ExecStart=/usr/local/bin/monerod –config-file /var/lib/monero/monerod.conf –detach –pidfile /var/lib/monero/monerod.pid
Move the file to
sudo mv $HOME/monerod.service /etc/systemd/system/monerod.service
Restart monerod in order for config change to take effect.
sudo systemctl daemon-reload
sudo systemctl enable monerod
sudo systemctl restart monerod
Check the systemd service with
journalctl -fu monerod
Review the logs for any errors. CTRL + C to exit.
tail -f /var/log/monero/monero.log
Allow the node to sync. This may take a few hours up to a few days depending on your node’s system resources.
Your node is completely synchronized the node status says height: n / n 100% and has the same block height as a public xmr block explorer such as https://blockchair.com/monero or http://xmrchain.net.
Check now your node’s block height with the following command.
Now you can easily connect to your newly created node using your preferred clients like Monerujo, CakeWallet, or Monero-GUI. All you need to do is enter the IP or hostname of your node into the designated remote node field. Congratulations!
