Moonbeam

Set up your Moonbeam Mainnet or Testnet (Moonbase-Alpha) node.

Prerequisites

Install Moonbeam / Moonbase Alpha

1. Download compiled binary

Download the latest release binary from PureState. In this tutorial, we are using v0.23.0

Terminal window
wget https://github.com/PureStake/moonbeam/releases/download/v0.23.0/moonbeam

2. Create a service account and copy the binary

Terminal window
#For Mainnet (Moonbeam) use:
adduser moonbeam_service --system --no-create-home
mkdir /var/lib/moonbeam-data
mv ./moonbeam /var/lib/moonbeam-data # assumption: ./moonbeam is your downloaded binary
sudo chown -R moonbeam_service /var/lib/moonbeam-data


#For Testnet (Moonbase Alpha) use:
adduser moonbeam_service --system --no-create-home
mkdir /var/lib/alphanet-data
mv ./moonbeam /var/lib/alphanet-data # assumption: ./moonbeam is your downloaded binary
sudo chown -R moonbeam_service /var/lib/alphanet-data

3. Create the systemd service file

After the installation of moonbeam, we are now ready to start the node, but to ensure it is running in the background and auto-restarts in case of a server failure, we will set up a service file using systemd.

📝

Note: In the service file below you need to replace "YOUR-NODE-NAME" and replace 50% RAM in MB for 50% of the actual RAM your server has (Example: --db-cache 16000 if your server has 32GB RAM). If you are connecting to Testnet instead (Moonbase Alpha), you will also need to change the path to /var/lib/alphanet-data/ and add --chain alphanet.

Terminal window
sudo tee <<EOF >/dev/null /etc/systemd/system/moonbeam.service

     --chain moonbeam \
     --name "YOUR-NODE-NAME" \

4. Enable and start the moonbeam service

Terminal window
sudo systemctl enable moonbeam.service
sudo systemctl start moonbeam.service

If everything was set-up correctly, your Moonbeam node should now be starting the process of synchronization. This will take several hours, depending on your hardware. To check the status of the running service or to follow the logs, use:

Terminal window
sudo systemctl status moonbeam.service
sudo journalctl -u moonbeam.service -f

Test your Moonbeam RPC connection

Once your Moonbeam node is fully synced, you can run a cURL request to see the status of your node:

Terminal window
curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "eth_syncing", "params":[]}' localhost:9933

If the node is successfully synced, the output from above will print {"jsonrpc":"2.0","result":false,"id":1}

EVM RPC endpoint URL

Axelar Network will be connecting to the EVM compatible Moonbeam, so your rpc_addr should be exposed in this format:

Terminal window
http://IP:PORT

Example: http://192.168.192.168:9933
