systemctl enable hornet-mainnet.service
systemctl start hornet-mainnet && journalctl -u hornet-mainnet -fIf everything went fine hornet should start up. Cancel the log output with CTRL + C
Allow traffic through firewall (ufw), if configured.
ufw allow 8081/tcp
ufw allow 15600/tcpYour Dashboard should be available via your IP address / hostname on port 8081 (eg. http://127.0.0.1:8081)
If you want remote access edit /opt/hornet-mainnet/config.json and change
bindAddress : 0.0.0.0:8081
Generate your password hash and salt with
/opt/hornet-mainnet/hornet tool pwdhashThe section should look something like this:
"dashboard": {
"bindAddress": "0.0.0.0:8081",
"dev": false,
"auth": {
"sessionTimeout": "72h",
"username": "admin",
"passwordHash": "d2be30670649d661b3edb8969bbc525aa86d00f8914ea2423ad09870b5b0dd15",
"passwordSalt": "0893a61b4c5a109149dc37c73fc3d0bf08ca54f0638b402f10f3c3eef376cb86"
}
},The dashboad shows your Peer ID. You need the peer ID to generate your connection string which you share with your neighbors. You can find neighbors via the community project http://nodesharing.wisewolf.de/ or the IOTA Discord.
Example:
/dns/testnet.hornetnode.com/tcp/15600/ 12D3KooWS7nyRgFjzgkethzi6SDdjmuAGooxDmnoLzyex7Lu4hKo
/ip4/80.58.56.41/tcp/15600/ 12D3KooWS7nyRgFjzgkethzi6SDdjmuAGooxDmnoLzyex7Lu4hKo
Neighbors are added via the Dashboard. Alternatively they can be added to the peering.json like in pre Chrysalis Hornet. But the format changed.
Example:
{
"peers": [
{
"alias": "Node1",
"multiAddress": "/ip4/85.10.52.22/tcp/15601/p2p/12D3KooWPNAjVAtFdbDzbtB3htTFaGDWQePBK2TSGZLx3wwrkA97"
},
{
"alias": "Node2",
"multiAddress": "/dns/node-1.testnetnode.com/tcp/15601/p2p/12D3KooWPJ2tQ1uCTSj6L6UNLarkbRBLqWvucot6UQsUreTxtvX3"
}
]
}Alias need to be entered in the order of your peer list.
