外部リレーノードのセットアップ(翻訳中)

This guide walks through setting up an external relay node.
Relay nodes do not have any keys, so they cannot produce blocks. Instead, relays act as proxies between the core network nodes and the internet, establishing a security perimeter around the core, block-producing network nodes. Since external nodes cannot communicate with block-producing nodes directly, relay nodes ensure that the integrity of the core nodes and the blockchain remains intact, even if one or more relays become compromised.
🌜 0. Prerequisites
a different computer/laptop/server/VM (not located on the same machine as your block-producing node)
⚙ 1. Set the relay node IP/port info
We call the current relay node NEW and the previous block producing or relay node EXISTING.
NEW_RELAY_NODE_IP can be discovered automatically with help from ifconfig.me​
NEW_RELAY_NODE_IP=$(curl http://ifconfig.me/ip)
NEW_RELAY_NODE_PORT=3001
EXISTING_NODE_IP=<IP OF MY EXISTING BLOCK PRODUCING OR RELAY NODE>
EXISTING_NODE_PORT=<PORT OF MY EXISTING BLOCK PRODUCING OR RELAY NODE>
🚧 2. Review the IP/port information before continuing
printf "NEW_RELAY_NODE_IP: $NEW_RELAY_NODE_IP \n\
NEW_RELAY_NODE_PORT: $NEW_RELAY_NODE_PORT \n\
EXISTING_NODE_IP: $EXISTING_NODE_IP \n\
EXISTING_NODE_PORT: $EXISTING_NODE_PORT \n"
🤹♀ 3. Set the node configuration data
echo export NODE_HOME=$HOME/cardano-my-node >> ~/.bashrc
echo export NODE_CONFIG=mainnet >> ~/.bashrc
echo export NODE_URL=cardano-mainnet >> ~/.bashrc
echo export NODE_BUILD_NUM=$(curl https://hydra.iohk.io/job/Cardano/iohk-nix/cardano-deployment/latest-finished/download/1/index.html | grep -e "build" | sed 's/.*build\/\([0-9]*\)\/download.*/\1/g') >> ~/.bashrc
echo export NETWORK_IDENTIFIER=\"--mainnet\" >> ~/.bashrc
echo export CARDANO_NODE_SOCKET_PATH="$NODE_HOME/db/socket" >> ~/.bashrc
source ~/.bashrc

Copy binaries and verify the correct version is installed.
sudo cp $(find ~/git/cardano-node/dist-newstyle/build -type f -name "cardano-cli") /usr/local/bin/cardano-cli
sudo cp $(find ~/git/cardano-node/dist-newstyle/build -type f -name "cardano-node") /usr/local/bin/cardano-node

🛑5. Review the NEW relay node topology file
cat $NODE_HOME/relaynode1/${NODE_CONFIG}-topology.json
Use pooltool.io and the get_buddies script to manage your NEW relay node's topology.
Alternatively, if you have multiple relay nodes you would like to connect to, add their configurations to your topology.json file.
Example snippet below:
  {
    "addr": "3.3.3.3",
    "port": 3002,
    "valency": 1
  },
🔥 6. Configure port-forwarding and/or firewall
Specific to your networking setup or cloud provider settings, ensure your relay node's ports are open and reachable. Use https://canyouseeme.org/ to verify.
👩💻 7. Configure existing relay or block producing node's topology
Finally, add your new NEW relay node IP/port information to your EXISTING node's topology file.
Same process as step 5 but for your EXISTING node.
🔄 8. Restart both NEW and EXISTING nodes for new configs to take effect
On NEW relay node,
cd $NODE_HOME
./startRelay.sh
On EXISTING relay / block producing node,
Scripts
Systemd
Scripts
cd $NODE_HOME
./stopStakePool.sh 
./startStakePool.sh
Systemd
## or if you are using systemd
sudo systemctl stop cardano-stakepool
sudo systemctl start cardano-stakepool
🎊 9. Verify the connection
On one of your node's tmux screen, press P to view the peer list. You should see the connection to other node's IP.
✨ Congrats on the new relay node.
Reminder, relay nodes should NOT contain any operational certifications, vrf, skey or cold keys.
