Manual node setup

If you want to setup fullnode manually follow the steps below

Setting up vars

Here you have to put name of your moniker (validator) that will be visible in explorer

NODENAME=<YOUR_MONIKER_NAME_GOES_HERE>

Save and import variables into system

JUNO_PORT=22
echo "export NODENAME=$NODENAME" >> $HOME/.bash_profile
if [ ! $WALLET ]; then
	echo "export WALLET=wallet" >> $HOME/.bash_profile
fi
echo "export JUNO_CHAIN_ID=uni-3" >> $HOME/.bash_profile
echo "export JUNO_PORT=${JUNO_PORT}" >> $HOME/.bash_profile
source $HOME/.bash_profile

Update packages

sudo apt update && sudo apt upgrade -y

Install dependencies

sudo apt install curl build-essential git wget jq make gcc tmux chrony -y

Install go

if ! [ -x "$(command -v go)" ]; then
  ver="1.18.2"
  cd $HOME
  wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
  sudo rm -rf /usr/local/go
  sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
  rm "go$ver.linux-amd64.tar.gz"
  echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> ~/.bash_profile
  source ~/.bash_profile
fi

Download and build binaries

cd $HOME
git clone https://github.com/CosmosContracts/juno
cd juno
git checkout v7.0.0-beta.2
make build && make install

Config app

junod config chain-id $JUNO_CHAIN_ID
junod config keyring-backend test
junod config node tcp://localhost:${JUNO_PORT}657

Init app

junod init $NODENAME --chain-id $JUNO_CHAIN_ID

Download genesis and addrbook

wget -qO $HOME/.juno/config/genesis.json "https://raw.githubusercontent.com/CosmosContracts/testnets/main/uni-3/genesis.json"
