sudo snap install go --classic

setup a user to run under, and build daemons:

sudo addgroup --gid 26660 --system kava && sudo adduser -uid 26660 --ingroup kava --system --home /var/lib/kava kava
sudo -sHu kava
cd ~
git clone https://github.com/Kava-Labs/kava.git
cd kava/
git checkout v0.14.2
make install

cat .kvd/config/priv_validator_key.json # save this info in a safe place --IF-- will be a validator node.

Configuration

edit .kvd/config/app.toml

minimum-gas-prices = "0.025ukava"

edit .kvd/config/config.toml

seeds = "[email protected]:26656"

optional ... in [instrumentation]

prometheus = true
namespace = "kava"

optional ... if a validator with sentries:

persistent_peers = "<insert peers here>"
pex = false
unconditional_peer_ids = "<insert peer ids here>"

OR if just a regular node:

persistent_peers = "[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:46656,[email protected]:26656,[email protected]:50056,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26666,[email protected]:26656"

exit # logout kava user, back to regular user ...

useful commands for getting sync status....

journalctl -fu kvd
watch -n 5 -- "curl -s 127.0.0.1:26657/status | jq .result.sync_info"

slow syncing?

Ya, it's slow ... quicksync.io to the rescue (note, file names below will not work, visit: https://kava.quicksync.io/ to get correct file names)

sudo -s 
apt install liblz4-tool aria2
cd /var/lib/kava/.kvd
