⚙️Installation

Update & upgrade tools:

sudo apt update && sudo apt upgrade -y
sudo apt install make net-tools curl git wget htop tmux build-essential jq make lz4 gcc unzip -y

Install GO:

cd $HOME
VER="1.23.2"
wget "https://golang.org/dl/go$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"
[ ! -f ~/.bash_profile ] && touch ~/.bash_profile
echo "export PATH=$PATH:/usr/local/go/bin:~/go/bin" >> ~/.bash_profile
source $HOME/.bash_profile
[ ! -d ~/go/bin ] && mkdir -p ~/go/bin

or just this to use go on other user:

[ ! -f ~/.bash_profile ] && touch ~/.bash_profile
echo "export PATH=$PATH:/usr/local/go/bin:~/go/bin" >> ~/.bash_profile
source $HOME/.bash_profile
[ ! -d ~/go/bin ] && mkdir -p ~/go/bin

Cloning Kopi repository and installing it locally:

rm -rf ${HOME}/kopi
git clone --quiet --depth 1 --branch v0.6.5 https://github.com/kopi-money/kopi.git ${HOME}/kopi
cd ${HOME}/kopi
make install

Check Kopi version

$HOME/go/bin/kopid version --long | tail

INITIA NODE:

Set var:

Port=25

echo "export WALLET="wallet"" >> $HOME/.bash_profile

Service:

sudo systemctl daemon-reload
sudo systemctl enable kopid.service
sudo systemctl start kopid

Stop service:

sudo systemctl stop kopid
sudo systemctl disable kopid

CHECK:

Check status:

sudo systemctl status kopid

Check log:

sudo journalctl -u kopid -f --no-hostname -o cat

Check Sync:

kopid status 2>&1 | jq .sync_info

Check validator info:

kopid status 2>&1 | jq .validator_info

Delete node:

Make sure you have backup your validator before do this action:

sudo systemctl stop kopid
sudo systemctl disable kopid
sudo rm -rf /etc/systemd/system/kopid.service
sudo systemctl daemon-reload
sudo rm -f $(which kopid)
sudo rm -rf $HOME/.kopid
sudo rm -rf $HOME/kopi
