Running a Celestia node is crucial for participating in the Celestia network. This guide covers various methods to set up and run a Celestia node, including binary executions.

Running Celestia with Binary

Prerequisites

   • Move the binary to /usr/bin with cp celestia-appd /usr/bin/.
   • Create and edit the systemd service file /etc/systemd/system/celestia-appd.service with appropriate configurations.
3. Manage Service:
   • Reload systemd: sudo systemctl daemon-reload
   • Restart celestia-appd: sudo systemctl restart celestia-appd
   • Enable on boot: sudo systemctl enable celestia-appd
   • Check logs: journalctl -u celestia-appd -f
