Start your node
Starting the node uses the command cardano-node run and a set of options.
You can get the complete list of available options with cardano-node run
--topology FILEPATH The path to a file describing the topology.--database-path FILEPATH Directory where the state is stored.--socket-path FILEPATH Path to a cardano-node socket--host-addr HOST-NAME Optionally limit node to one ipv6 or ipv4 address--port PORT The port number--config NODE-CONFIGURATION Configuration file for the cardano-node--validate-db Validate all on-disk database files--shutdown-ipc FD Shut down the process when this inherited FD reaches EOF--shutdown-on-slot-synced SLOT Shut down the process after ChainDB is synced up to thespecified slot-h,--help Show this help text
To start the node, run the following command from inside the relay directory:
cardano-node run \--topology testnet-topology.json \--database-path db \--socket-path db/node.socket \--host-addr x.x.x.x \--port 3001 \--config testnet-config.json
The above command will create a db directory inside the relay directory
Replace x.x.x.x with your public IP
Open a new terminal or ssh session
Create the environment variable CARDANO_NODE_SOCKET_PATH
export CARDANO_NODE_SOCKET_PATH=~/relay/db/node.socket
Check whether the node is syncing by fetching the current tip, a couple of times, slotNo should be increasing. --testnet-magic 1097911063 identifies the Shelley testnet
