Run a tracing node
Geth's debug
and txpool
APIs and OpenEthereum's trace
module provide non-standard RPC methods for getting a deeper insight into transaction processing. Supporting these RPC methods is important because many projects, such as The Graph, rely on them to index blockchain data.
To use the supported RPC methods, you need to run a tracing node. This guide covers the steps on how to setup and sync a tracing node on Moonriver.
Pre-Requisites
sudo apt update -y && sudo apt upgrade -y && sudo apt autoremove -y
sudo apt install -y git make wget gcc pkg-config libusb-1.0-0-dev libudev-dev jq gcc g++ curl libssl-dev screen apache2-utils build-essential pkg-config
Setting up Firewall
Set explicit default UFW rules
sudo ufw default deny incoming
sudo ufw default allow outgoing
Allow SSH
sudo ufw allow 22/tcp
Allow remote RPC connections with Moonriver node (The default port for parachains is 9944
and 9945
for the embedded relay chain)
sudo ufw allow from ${REMOTE.HOST.IP} to any port 9944 9945
Not advised to allow all or unknown IP address to RPC port
Enable Firewall
sudo ufw enable
Building a Node on Moonriver
Download the Latest Release Binary
Check release binary page and take the following steps to download the latest version:
Create a directory to store the binary and chain data (you might need sudo
)
mkdir /var/lib/moonriver-data
Use wget
to grab the latest release binary and output it to the directory created in the previous step:
wget https://github.com/moonbeam-foundation/moonbeam/releases/download/v0.42.1/moonbeam \
-O /var/lib/moonriver-data/moonbeam
To verify that you have downloaded the correct version, you can run the following command in your terminal
sha256sum /var/lib/moonriver-data/moonbeam
You should receive the following output:
9b645b2fd9e575b26ea727e96dc2a81486a73461bb961ba33ea2136e4c9060d8
Setup the Wasm Overrides (required for a tracing node)
You'll need to create a directory for the Wasm runtime overrides and obtain them from the Moonbeam Runtime Overrides repository on GitHub
git clone https://github.com/moonbeam-foundation/moonbeam-runtime-overrides.git
Move the Wasm overrides into your on-chain data directory:
mv moonbeam-runtime-overrides/wasm /var/lib/moonriver-data
Delete the override files for the networks that you aren't running
rm /var/lib/moonriver-data/wasm/moonbeam-runtime-* && rm /var/lib/moonriver-data/wasm/moonbase-runtime-*
Set permissions for the overrides
chmod +x /var/lib/moonriver-data/wasm/*
Create the Configuration File
The next step is to create the systemd configuration file, you'll need to:
Replace
INSERT_YOUR_NODE_NAME
in two different places with the preffered name (it specifies a human-readable name for the node, which can be seen on telemetry, if enabled)--db-cache
specifies the memory the database cache is limited to use. It is recommended to set it to 50% of the actual RAM your server has. For example, for 128 GB RAM, the value must be set to64000
. The minimum value is2000
, but it is below the recommended specsDouble-check that the binary is in the proper path as described below (ExecStart)
Double-check the base path if you've used a different directory
Name the file
/etc/systemd/system/moonriver.service
Ensure that you grant execute permission to the binary file
sudo chmod +x /var/lib/moonriver-data/moonbeam
sudo nano /etc/systemd/system/moonriver.service
Copy/Paste and edit INSERT_YOUR_NODE_NAME
and --db-cache
according to your parameters:
[Unit]
Description="Moonriver service"
After=network.target
StartLimitIntervalSec=0
[Service]
Type=simple
Restart=on-failure
RestartSec=10

SyslogIdentifier=moonbeam

--rpc-port 9944 \
--execution wasm \
--wasm-execution compiled \
--state-pruning archive \
--trie-cache-size 1073741824 \
--runtime-cache-size 64 \
--ethapi debug,trace,txpool \
--wasm-runtime-overrides /var/lib/moonriver-data/wasm \
--unsafe-rpc-external \
--rpc-cors all \
--prometheus-port 6060 \
--db-cache 64000 \
--base-path /var/lib/moonriver-data \
--chain moonriver \
--name "infradao-moonriver" \
-- \
--name "infradao-moonriver (Embedded Relay)"
Ctrl+X and Y to save changes
systemctl enable moonriver.service #enable moonriver service at system startup
sudo systemctl daemon-reload #refresh systemd configuration when changes made
sudo systemctl start moonriver.service #start moonriver
sudo systemctl stop moonriver.service #stop moonriver
journalctl -f -u moonriver.service #follow logs of moonriver service
The logs should look like below and indicate that your node syncs and is expected to reach chainhead in about a week
Syncing 27.0 bps, target=#6051603 (30 peers), best: #3053702 (0xe669…1876), finalized #918931 (0x6587…f763), ⬇ 484.9kiB/s ⬆ 0.5kiB/s
Maintain Your Node
As Moonbeam development continues, it will sometimes be necessary to upgrade your node software.
To update moonriver client, you can keep your existing chain data in tact, and only update the binary by following these steps:
Stop the systemd service
sudo systemctl stop moonriver.service
Remove the old binary file
rm /var/lib/moonriver-data/moonbeam
Get the latest version of the Moonbeam release binary on GitHub and run the following command to update to that version (ensure to replace
INSERT_NEW_VERSION_TAG
with actual version)
wget https://github.com/moonbeam-foundation/moonbeam/releases/download/INSERT_NEW_VERSION_TAG/moonbeam \
-O /var/lib/moonriver-data/moonbeam
Update permissions
chmod +x /var/lib/moonriver-data/moonbeam
Start moonriver service
systemctl start moonriver.service
