💻Installation

Server preparation

apt update && apt upgrade -y

apt install curl iptables build-essential git wget jq make gcc nano tmux htop nvme-cli pkg-config libssl-dev libleveldb-dev tar clang bsdmainutils ncdu unzip libleveldb-dev -y

Install GO

ver="1.21.3"
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" >> $HOME/.bash_profile
source $HOME/.bash_profile
go version

Node installation

git clone https://github.com/JackalLabs/canine-chain && cd canine-chain
git checkout v4.1.0-beta.2
make install

canined version --long | grep -e version -e commit
#version: v4.1.0-beta.2
#commit: 4e64e646fa8036eb48e86cb512b0da81bec5e283

We initialize the node to create the necessary configuration files

canined init UTSA_guide --chain-id lupulella-2

Download Genesis

wget -O $HOME/.canine/config/genesis.json "https://raw.githubusercontent.com/JackalLabs/jackal-chain-assets/main/testnet/genesis.json"

# Проверим генезис
sha256sum ~/.canine/config/genesis.json

At this stage, we can download the address book

Set up node configuration

canined config chain-id lupulella-2
canined config keyring-backend os
sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.0025ujkl\"/;" ~/.canine/config/app.toml
external_address=$(wget -qO- eth0.me)
sed -i.bak -e "s/^external_address *=.*/external_address = \"$external_address:26656\"/" $HOME/.canine/config/config.toml
peers="5eedbfbe64b942f4ab54db3842acf3bfab034c24@161.97.74.88:46656"
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.canine/config/config.toml
seeds="84f520678ef59ea02f942fa6323ec562ca5a3249@45.79.161.178:26656,cecc087977336da1e9ccd2c50097cd9e7d5e1874@141.95.33.39:26656"
sed -i.bak -e "s/^seeds =.*/seeds = \"$seeds\"/" $HOME/.canine/config/config.toml

(OPTIONAL) Set up pruning

pruning="custom"
pruning_keep_recent="1000"
pruning_interval="10"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.canine/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.canine/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.canine/config/app.toml

(OPTIONAL) Set up indexer

indexer="null"
sed -i -e "s/^indexer *=.*/indexer = \"$indexer\"/" $HOME/.canine/config/config.toml

(OPTIONAL) Enable/Disable Snapshots

snapshot_interval=1000
sed -i.bak -e "s/^snapshot-interval *=.*/snapshot-interval = \"$snapshot_interval\"/" ~/.canine/config/app.toml

Create a service file

sudo tee /etc/systemd/system/canined.service > /dev/null <<EOF
[Unit]
Description=canined
After=network-online.target

[Service]
User=$USER
ExecStart=$(which canined) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

systemctl daemon-reload
systemctl enable canined
systemctl restart canined && journalctl -u canined -f -o cat

If peers do not cling for a long time or you see errors error: wrong Block.Header.AppHash, you need to use State sync or boot from a Snapshot
