​
Overview

  • Prepare the Full Node machine.
  • Install Heimdall and Bor packages on the Full Node machine.
  • Configure the Full node.
  • Start the Full node.
It is essential to follow the outlined sequence of actions precisely, as any deviation may lead to potential issues.

​
Install packages

​
Prerequisites

  • One machine is needed.
  • Bash is installed on the machine.

​
Heimdall

  • Install the default latest version of sentry for Mainnet: 
    curl -L https://raw.githubusercontent.com/0xPolygon/install/heimdall-v2/heimdall-v2.sh | bash -s -- <version> <network> <node_type>
    or install a specific version, node type (sentry or validator), and network (mainnet or amoy). All release versions can be found on Heimdall GitHub repository. 
    # Example:
# curl -L https://raw.githubusercontent.com/maticnetwork/install/heimdall-v2/heimdall-v2.sh | bash -s -- v0.2.15 mainnet validator

​
Bor

  • Install the default latest version of sentry for Mainnet: 
    curl -L https://raw.githubusercontent.com/0xPolygon/install/main/bor.sh | bash -s -- <version> <network> <node_type>
    or install a specific version, node type (sentry or validator), and network (mainnet or amoy). All release versions could be found on Bor Github repository. 
    # Example:
# curl -L https://raw.githubusercontent.com/0xPolygon/install/main/bor.sh | bash -s -- v2.2.9 mainnet sentry

​
Configuration

​
Configure Heimdall

  • Initialize Heimdall configs
# For mainnet
sudo -u heimdall heimdalld init <MONIKER> --chain-id=<CHAIN_ID> --home /var/lib/heimdall
Where CHAIN_ID is heimdallv2-80002 for amoy and heimdallv2-137 for mainnet Then, edit the configuration files under /var/lib/heimdall/config
The templates for each supported network are available here
Download the genesis.json file and place it under /var/lib/heimdall/config/ Use the following commands based on your target network: 
cd /var/lib/heimdall/config
curl -fsSL <BUCKET_URL> -o genesis.json
Where BUCKET_URL is

​
Configure service files for Bor and Heimdall

After successfully installing Bor and Heimdall through packages, their service file could be found under /lib/systemd/system, and Bor’s config file could be found under /var/lib/bor/config.toml. You will need to check and modify these files accordingly.
  • Make sure the chain is set correctly in /lib/systemd/system/heimdalld.service file. Open the file with following command sudo vi /lib/systemd/system/heimdalld.service
    • In the service file, set --chain to mainnet or amoy accordingly
Save the changes in /lib/systemd/system/heimdalld.service.
  • Make sure the chain is set correctly in /var/lib/bor/config.toml file. Open the file with following command sudo vi /var/lib/bor/config.toml
    • In the config file, set chain to mainnet or amoy accordingly.
    • To enable Archive mode you can optionally enable the following flags: 
      gcmode "archive"

[jsonrpc]
  [jsonrpc.ws]
    enabled = true
    port = 8546
    corsdomain = ["*"]
Save the changes in /var/lib/bor/config.toml.

​
(Optional) Start Heimdall from snapshot

In case you want to start Heimdall from a snapshot,
you can download it, and extract in the data folder. Examples of snapshots can be found here https://all4nodes.io/Polygon, and they are managed by the community. e.g.: 
lz4 -dc polygon-heimdall-24404501-25758577.tar.lz4 | tar -x

​
Start services

Reloading service files to make sure all changes to service files are loaded correctly. 
sudo systemctl daemon-reload
Verify the installation by checking the Heimdall version on your machine: 
heimdalld version
It should return the version of Heimdall you installed. Start Heimdall, Heimdall rest server, and Heimdall bridge. 
sudo service heimdalld start
You can also check Heimdall logs with the following command: 
journalctl -u heimdalld.service -f
At this point, please make sure that Heimdall is synced completely, and only then start Bor. If you start Bor without Heimdall syncing completely, you will run into issues frequently.
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
Now, once Heimdall is synced, run: 
sudo service bor start
You can check Bor logs using the following command: 
journalctl -u bor.service -f
