Cardano private network

Prerequisites

For folder structure, we will use the guild operator scripts.

mkdir "$HOME/tmp";cd "$HOME/tmp"
curl -sS -o guild-deploy.sh https://github.com/cardano-community/guild-operators/master/scripts/cnode-helper-scripts/guild-deploy.sh
chmod 755 guild-deploy.sh

For cardano-node, we will use the latest pre-built binaries available which can be downloaded automatically in the ~/.local/bin directory.

./guild-deploy.sh -s d

Update node producer pool name

Before you go ahead with starting your node, update value for POOL_NAME in $CNODE_HOME/scripts/env.

POOL_NAME="pool1"

Source the changes

. "${HOME}/.bashrc"

For latest guild operator commands and to build the binaries locally using cabal, refer the guild operator documenation. (https://cardano-community.github.io/guild-operators/basics/)

Configuring the deployment

All parameters are configured via environment variables (env.sh) The POOL_NAME mentioned in the guild operator env file should match with the POOL_NAME mentioned for the private network so that the keys can be copied and the node can start as block producer.

source {your_environment_file}

Update the genesis files with a new start time:

./update-genesis-start-time.sh

Every execution of update-genesis-start-time.sh will generate a unique genesis file, because the parameter "systemStart" is the result of date +${DELAY}. If you've configured your enviroment with DELAY=5, you will have 5min to deploy the testnet. If no block producer is present at that point in time, the network (for that genesis hash) will be dead on arrival.

This will also copy the config files and the keys to run the cardano node.

Deploying private instance

1. Deploy as a systemd service Execute the below command to deploy your node as a systemd service (from the respective scripts folder):

cd $CNODE_HOME/scripts
./cnode.sh -d

2. Start the service Run below commands to enable automatic start of service on startup and start it.

sudo systemctl start cnode.service

3. Check status and stop/start commands Replace status with stop/start/restart depending on what action to take.

sudo systemctl status cnode.service

Important

In case you see the node exit unsuccessfully upon checking status, please verify you've followed the transition process correctly as documented below, and that you do not have another instance of node already running. It would help to check your system logs (/var/log/syslog for debian-based and /var/log/messages for Red Hat/CentOS/Fedora systems, you can also check journalctl -f -u to examine startup attempt for services) for any errors while starting node.

Next steps:

You can use gLiveView to monitor your node that was started as a systemd service.

cd $CNODE_HOME/scripts
./gLiveView.sh

Generate Addresses and fund:

cd scripts
./step1-generate-utxo-keys-and-address.sh

Send funds to the address from the bootstrap node:

cd scripts
./faucet.sh <AMOUNT_IN_LOVELACE> <ADDRESS>

Running a Relay:

To run a relay node, the config file generated for the block producer node will be used. The topology file for the relay node has to be updated to connect to the block producer node. For setup,

1. start with same pre-requisites but do not set the pool name for this instance
2. Copy the genesis files from the block producer for relay node
3. Update topology file to be able to connect to the block producer node
4. Run relay node as systemd service and let it sync up.

Running grafana on relay node for monitoring

Once your Cardano pool is successfully set up, then comes the most beautiful part - setting up your Dashboard and Alerts!

Runing Cardano db-sync

Prerequisites

Ensure the older database is dropped and there is no data from previous run network. Set up the postgres for the db sync (https://cardano-community.github.io/guild-operators/Appendix/postgres/)

Setting up db-sybc as systemd service

The db-sync can be easily set using guild operator scripts (https://cardano-community.github.io/guild-operators/Build/dbsync/)
