Cardano Node CLI

The first step in using cardano node is to install the node sw and start running. Please note that this is not needed if you plan to use demeter.run that was explained earlier

To install cardano node and cardano-cli get the latest version from IOHK github. Although you can compile the node yourself, its easier to use precompiled node in the beginning

For node version 1.34.4 here is the link

https://update-cardano-mainnet.iohk.io/cardano-node-releases/cardano-node-1.35.4-linux.tar.gz

Once you install the node, copy it to /usr/local/bin. Cardano has two testnests named preview and preprod. It is preferable to use preview testnet

Download the topology files from here for preview testnet

The node can be started with following comands

#!/bin/bash
DIRECTORY=/home/cardanouser/cardano-my-node
PORT=6000
HOSTADDR=0.0.0.0
TOPOLOGY=${DIRECTORY}/topology.json
DB_PATH=${DIRECTORY}/db
SOCKET_PATH=${DIRECTORY}/db/socket
CONFIG=${DIRECTORY}/config.json
/usr/local/bin/cardano-node run +RTS -N --disable-delayed-os-memory-return -I0.3 -Iw600 -A16m -F1.5 -H2500M -qb -qg1 -c -S -RTS --topology ${TOPOLOGY} --database-path ${DB_PATH} --socket-path ${SOCKET_PATH} --host-addr ${HOSTADDR} --port ${PORT} --config ${CONFIG}

Testnet will take sometime to sync.

Cardano CLI

Once the node is synced, cardano coomandline can be used to interact. Following github gives details on commands that can be used
