Cardano P2P Deployment
The below instruction covers how to deploy P2P functionality to Cardano relay nodes and disable legacy manual Topology-Updater functionality.
IMPORTANT: P2P on mainnet is only intended to be ran on a single relay at this time. (v1.35.7) Continue to run any other relays with P2P disabled using the legacy topology.
Github Repository:
P2P Configuration
terminal:~$ cd $CNODE_HOME/files
terminal:~$ mv topology.json topology.json.bk
terminal:~$ wget https://book.world.dev.cardano.org/environments/mainnet/topology-p2p.json
terminal:~$ mv topology-p2p.json topology.json
Add block producer and second relay to the localRoots section:
#Check our sample topology.json in the repository section for guidance.
terminal:~$ vi topology.json
"localRoots": [
{
"accessPoints": [
{
"address": "BlockProducerIP",
"port": 6001
},
{
"address": "SecondRelayIP",
"port": 6002
}
],
"advertise": false,
"valency": 1
}
],
Add P2P flag configuration to the config.json cofiguration file:
terminal:~$ cd $CNODE_HOME/files
terminal:~$ vi config.json
"EnableP2P": true,
#There are additional settings that can be added to the the config.json file. Check those here.[1].
Disable legacy Topology-Updater functionality:
terminal:~$ cd $CNODE_HOME/scripts
terminal:~$ chmod -x topologyUpdater.sh
terminal:~$ sudo systemctl stop cnode-tu-fetch.service
terminal:~$ sudo systemctl stop cnode-tu-restart.timer
terminal:~$ sudo systemctl stop cnode-tu-restart.service
terminal:~$ sudo systemctl disable cnode-tu-fetch.service
terminal:~$ sudo systemctl disable cnode-tu-restart.timer
terminal:~$sudo systemctl disable cnode-tu-restart.service
terminal:~$sudo systemctl restart cnode.service
