Build a node from source

Overview​

This guide demonstrates how to compile a Ronin binary on your own using the Ronin CLI (command-line interface), instead of running a packed binary from Docker. With the Ronin CLI, you can run a full node (default) or an archive node (retaining all historical state).

Prerequisites​

Step 1. Download Ronin source​

To download the Ronin source code, clone the GitHub repository. We recommend that you create a home ronin directory first and download all the Ronin-related software there:

mkdir -p ~/roninchain && cd ~/roninchain
git clone git@github.com:axieinfinity/ronin.git

Step 2. Build the binary​

Create a ronin binary from source:

cd ronin
make ronin

The make ronin command creates a ronin binary in the ./build/bin directory.

Step 3. Add the binary to PATH​

To run the ronin binary without specifying its location in each command, add the directory where the binary is located to your $PATH environment variable:

export PATH=$PATH:/path-to-ronin-binary/

If run from the ronin directory that you cloned, then the command is as follows:

export PATH=$PATH:./build/bin/

Step 4. Initialize the genesis block​

To set up the origin state of the chain, initialize the genesis block. In your command, include the path to the genesis files located in the repository's genesis directory, and the path where you store the node's data, such as ~/roninchain/data.

ronin init --datadir ~/roninchain/data genesis/mainnet.json

Whenever you build the node or upgrade the software with a new hardfork, always initialize the genesis block by running the preceding command.

Step 5. Run the node​

To run a full (non-validator) Ronin node, use the following command:

ronin --http.api eth,net,web3,consortium --networkid 2020 --discovery.dns enrtree://AIGOFYDZH6BGVVALVJLRPHSOYJ434MPFVVQFXJDXHW5ZYORPTGKUI@nodes.roninchain.com --datadir ~/roninchain/data --port 30303 --http --http.corsdomain '*' --http.addr 0.0.0.0 --http.port 8545 --http.vhosts '*' --ws --ws.addr 0.0.0.0 --ws.port 8546 --ws.origins '*'

This command starts ronin in full sync mode, causing it to download all blocks from the start of the Ronin network and execute all transactions in these blocks.

To run an archive node, modify the preceding command by adding the --syncmode full and --gcmode archive flags:

ronin --syncmode full --gcmode archive --http.api ...

Configuration​

Instead of passing numerous flags to the ronin binary, you can pass a configuration file as follows:

ronin --config /path/to/your_config.toml

To get an idea of how the file should look like, use the dumpconfig subcommand to export your existing configuration:

ronin --your-favourite-flags dumpconfig
