Full Node Deployment

Full Node Deployment (Matic mainnet)

We have created simple Ansible playbooks to setup a full node.


  • Ansible should be installed on local machine with Python3.x. The setup will not work if you have Python2.x.
    • To install ansible with Python 3.x you can use this command pip3 install ansible. This will install Python 3 dependencies as well as ansible.
  • Check https://github.com/maticnetwork/node-ansible#requirements for requirements
  • You will also need to make sure that Go is not installed on your VM / Machine. Setting up your full node through ansible will run into issues if you have Go already installed, as ansible requires specific packages of Go to be installed.
  • You will also need to make sure that your VM / Machine does not have any previous setups for Matic Validator or Heimdall or Bor. You will need to delete them as your setup will run into issues.

Setup full node for Matic mainnet

  • Ensure you have access to the remote machine or VM that the full node is being setup on. Refer https://github.com/maticnetwork/node-ansible#setup for more details.

  • Clone the https://github.com/maticnetwork/node-ansible repo

  • cd node-ansible

  • Edit the inventory.yml file and insert your IP(s) in the sentry->hosts section. Refer https://github.com/maticnetwork/node-ansible#inventory for more details.

  • Check if remote machine is reachable by running ansible sentry -m ping

  • For a test run to confirm if the correct remote machine / VM is configured, run the following command:

    ansible-playbook -l sentry playbooks/network.yml --extra-var="bor_branch=v0.2.0 heimdall_branch=v0.2.0 network_version=mainnet-v1 node_type=sentry/sentry" --list-hosts

    It should output the remote machine IP(s) you have configured

  • Setup the full node with this command:

    ansible-playbook -l sentry playbooks/network.yml --extra-var="bor_branch=v0.2.0 heimdall_branch=v0.2.0 network_version=mainnet-v1 node_type=sentry/sentry"

  • In case you run into any issues, delete and clean the whole setup using

    ansible-playbook -l sentry playbooks/clean.yml

  • Login to the remote machine

  • Configure the following in ~/.heimdalld/config/config.toml:

    • moniker=<enter unique identifier>
    • seeds="f4f605d60b8ffaaf15240564e58a81103510631c@,4fb1bc820088764a564d4f66bba1963d47d82329@"
  • Configure the following in ~/.heimdalld/config/heimdall-config.toml:

    • eth_rpc_url =<insert Infura or any full node RPC URL to Ethereum>
  • Add the following flag in ~/node/bor/start.sh to the bor start params:

--bootnodes "enode://0cb82b395094ee4a2915e9714894627de9ed8498fb881cec6db7c65e8b9a5bd7f2f25cc84e71e89d0947e51c76e85d0847de848c7782b13c0255247a6758178c@,enode://88116f4295f5a31538ae409e4d44ad40d22e44ee9342869e7d68bdec55b0f83c1530355ce8b41fbec0928a7d75a5745d528450d30aec92066ab6ba1ee351d710@"
  • In case you want to turn trace on for Bor, add the following flag to the bor start params in ~/node/bor/start.sh:

    • --gcmode 'archive'
  • Run the full node with the following commands:

    • sudo service heimdalld start

    • sudo service heimdalld-rest-server start

      Once Heimdall is synced, run

    • sudo service bor start

  • Check logs:

    • Heimdall - journalctl -u heimdalld.service -f
    • Heimdall Rest Server - journalctl -u heimdalld-rest-server.service -f
    • Bor - journalctl -u bor.service -f
  • To check if Heimdall is synced

    • On the remote machine/VM, run curl localhost:26657/status
    • In the output, catching_up value should be false
