Install celestia-app ​

This tutorial will guide you through installing celestia-app, both from source and with a pre-built binary

Celestia-app is the software that allows you to run validator nodes and provide RPC endpoints.

Building binary from source ​

This section of the tutorial presumes you completed the steps in setting up your own environment.

The steps below will create a binary file named celestia-appd inside $HOME/go/bin folder which will be used later to run the node. Be sure to select the correct network to install the binary for.

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

   bash

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

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

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

   Mainnet BetaMochaArabica

   bash

   git checkout tags/v3.1.1

   git checkout tags/v3.1.1

   bash

   git checkout tags/v3.1.1-mocha

   git checkout tags/v3.1.1-mocha

   bash

   git checkout tags/v3.1.1-arabica

   git checkout tags/v3.1.1-arabica

3. Build and install the celestia-appd binary:

   bash

   make install

   make install

4. To check if the binary was successfully installed you can run the binary using the --help flag:

   sh

   celestia-appd --help

   celestia-appd --help

You will see an output with the menu for celestia-appd. Learn more on the helpful CLI commands page

Installing a pre-built binary ​

Installing a pre-built binary is the fastest way to get started with your Celestia consensus node. Releases after celestia-app v1.3.0 should have these binaries available.

The steps below will download a binary file named celestia-appd. Depending on the setup that you choose during installation, the celestia-appd binary will be available at either:

• $HOME/celestia-app-temp/celestia-appd
• /usr/local/bin/celestia-appd

Pre-built binaries are available for:

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

To install the latest pre-built binary you can run this command in your terminal:

bash -c "$(curl -sL https://docs.celestia.org/celestia-app.sh)"

bash -c "$(curl -sL https://docs.celestia.org/celestia-app.sh)"

Follow the instructions in the terminal output to choose your installation preferences.

Ports ​

When interacting with a consensus node, you may need to open ports on your machine to allow communication between nodes, such as bridge nodes. It is essential that specific ports are accessible. Make sure that your firewall allows connections to the correct ports.

If you run a node on a cloud server, make sure that the ports are open on the server's firewall. If you run a node at home, make sure that your router allows connections to the correct ports.

For example, validator ports 9090 and 26657 need to be accessible by the bridge, and port 2121 is required for P2P connections for all node types.

The following ports are used by Celestia app nodes:
