Install celestia-node ​

Installing from source ​

This section goes over building and installing celestia-node. This tutorial assumes you completed the steps in setting up your development environment.

Install the celestia-node binary by running the following commands:

  1. Remove any existing copy of celestia-node, clone the repository, and change into the directory:

    bash
    cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/
    cd $HOME
rm -rf celestia-node
git clone https://github.com/celestiaorg/celestia-node.git
cd celestia-node/

  2. Check out to the desired version, based on the network you will use:

    bash
    git checkout tags/v0.20.4
    git checkout tags/v0.20.4
    bash
    git checkout tags/v0.20.4-mocha
    git checkout tags/v0.20.4-mocha
    bash
    git checkout tags/v0.20.4-arabica
    git checkout tags/v0.20.4-arabica

  3. Build the celestia binary:

    a. Standard build

    bash
    make build
    make build

    b. Experimental build

    OPTIONAL

    If you're a node operator comfortable with experimental features and seeking optimal performance with minimal RAM usage, this option is recommended for you.

    bash
    make build-jemalloc
    make build-jemalloc

    This build option enables CGO, and downloads and installs jemalloc. Learn more about the build command.

  4. Install the binary:

    bash
    make install
    make install

  5. Build the cel-key utility:

    bash
    make cel-key
    make cel-key

  6. Verify that the binary is working and check the version:

    bash
    celestia version
    celestia version

The output will show the semantic version of celestia-node, commit hash, build date, system version, and Golang version.

Installing a pre-built binary ​

Installing a pre-built binary is the fastest way to get started with your Celestia data availability node. Releases after celestia-node v0.13.3 have these binaries available.

The installation script will download a binary file named celestia. Depending on your chosen installation option, the celestia binary will be available at one of these locations:

  • $GOPATH/bin/celestia (if Go is installed)
  • /usr/local/bin/celestia
  • $HOME/celestia-node-temp/celestia

Pre-built binaries are available for:

  • Operating systems: Darwin (Apple), Linux
  • Architectures: x86_64 (amd64), arm64

Installation Options ​

You can install the latest version or specify a particular version:

bash
# Install latest version
bash -c "$(curl -sL https://docs.celestia.org/celestia-node.sh)"

# Install specific version, Mainnet Beta in this example
bash -c "$(curl -sL https://docs.celestia.org/celestia-node.sh)" -- -v v0.20.4
# Install latest version
bash -c "$(curl -sL https://docs.celestia.org/celestia-node.sh)"

# Install specific version, Mainnet Beta in this example
bash -c "$(curl -sL https://docs.celestia.org/celestia-node.sh)" -- -v v0.20.4

The script will:

  1. Detect your system's operating system and architecture
  2. Download the appropriate binary
  3. Verify the checksum for security
  4. Provide installation location options based on your environment:
    • If Go is installed:
      • Go bin directory ($GOPATH/bin)
      • System bin directory (/usr/local/bin)
      • Keep in current directory
    • If Go is not installed:
      • System bin directory (/usr/local/bin)
      • Keep in current directory

Follow the instructions in the terminal output to choose your installation preferences. After installation, you can verify the setup by checking the version:

bash
celestia version && celestia --help
celestia version && celestia --help

View the script to learn more about what it is doing.

Note: The script maintains a log file at $HOME/celestia-node-temp/logfile.log for troubleshooting purposes.

Next steps ​

First, we recommend reading the overview of our node types, if you haven't yet.

Now that you've installed Celestia Node, it's time to pick your node type and run your node!

If you're planning to run a light node, we recommend the node RPC CLI tutorial.

Upgrading your binary ​

To upgrade your binary, you can install the latest version from the instructions above and restart your node. If you run into any issues, Refer to the troubleshooting section.
