How to run a Kepler Node


  • Linux (x86-64 only) or MacOS
  • Relatively recent hardware
  • Some Linux command line knowledge very helpful
  • rust 1.31+ (use rustup- i.e. curl -sSf | sh; source $HOME/.cargo/env)
    • if rust is already installed, you can simply update version with rustup update

Downloading the Software

The latest Kepler release can be found on the project Release Page. Binaries are currently provided for Linux and OSX.

Distribution-specific releases will likely appear over time, and will be listed here.


Linux (all distributions)

Download the zipped binary to your machine, and unzip it using the terminal. This will unzip a single file called kepler, which contains both the server and wallet software.

For now, we'd recommend placing this somewhere relative to your home directory, and editing your path environment variable to ensure the kepler executable is available from wherever you run it. All of this can be done by running the following commands in the directory to which you downloaded kepler.

mkdir -p ~/kepler
tar xzf kepler-v1.0.0-479973573-linux-amd64.tgz -C ~/kepler
echo export 'PATH=~/kepler:$PATH' >> ~/.bashrc
source ~/.bashrc

Running a Kepler Node

After following the installation steps, simply run Kepler:


Or, to run a Floonet (i.e. test network) node:

kepler --floonet

And that is it! The Kepler TUI (Text-User-Interface) should appear and your node should automatically sync up with the blockchain.

Configuring your Kepler node

By default, your Kepler node keeps all of its configuration files and data in the ~/.kepler directory under your user home. The main server configuration file can be found in the file ~/.kepler/main/kepler-server.toml (~/.kepler/floo/kepler-server.toml for Floonet). This file is fully documented, and contains many configuration options for your Kepler server. Leaving these values at their defaults should work for most people who simply want to run a node.

Running from a Custom Directory

You can also keep Kepler's data and configuration files in a custom directory. From the directory in which you want Kepler to store its files, run:

kepler server config

This will create a kepler-server.toml file in the current directory that is configured to place its data files in the same directory. The kepler command will always check the current directory for a kepler-server.toml file, and if one is found it will use it instead of ~/.kepler/main/kepler-server.toml.
