Arkeo Testnet Setup

Prerequisites

Install Go

  1. Update and configure system parameters:

    sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get install -y build-essential curl wget jq make gcc chrony git
sudo su -c "echo 'fs.file-max = 65536' >> /etc/sysctl.conf"
sudo sysctl -p

  2. Install Go:

    sudo rm -rf /usr/local/.go
wget https://go.dev/dl/go1.21.13.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.21.13.linux-amd64.tar.gz
sudo cp /usr/local/go /usr/local/.go -r
sudo rm -rf /usr/local/go

  3. Update environment variables to include Go:

    cat <<'EOF' >>$HOME/.profile
export GOROOT=/usr/local/.go
export GOPATH=$HOME/go
export GO111MODULE=on
export PATH=$PATH:/usr/local/.go/bin:$HOME/go/bin

export ARKEO_PORT="<your-port>"
EOF
source $HOME/.profile

  4. Verify Go installation:

    go version

    Expected output: go version go1.21.13 linux/amd64

Install and Configure Arkeo Binary

1. Clone and install Arkeo:

git clone https://github.com/arkeonetwork/arkeo
cd arkeo
git checkout master
TAG=testnet make install

2. Configure the binary:

arkeod keys add <key-name>
arkeod config set client node tcp://localhost:${ARKEO_PORT}57
arkeod config set client keyring-backend test
arkeod config set client chain-id arkeo-testnet-3
arkeod init <your-custom-moniker> --chain-id arkeo-testnet-3
sudo ufw allow ${ARKEO_PORT}56/tcp

Download Genesis File

curl -s http://seed31.innovationtheory.com:26657/genesis | jq '.result.genesis' > $HOME/.arkeo/config/genesis.json

Configure App Settings

**Pruning, Gas Prices, and Prometheus: **

sed -i -e "s/^pruning *=.*/pruning = \"custom\"/" $HOME/.arkeo/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"100\"/" $HOME/.arkeo/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"50\"/" $HOME/.arkeo/config/app.toml
sed -i 's|minimum-gas-prices =.*|minimum-gas-prices = "0.001uarkeo"|g' $HOME/.arkeo/config/app.toml
sed -i 's|swagger =.*| swagger = true|g' $HOME/.arkeo/config/app.toml

Configure Seeds and Peers

Set Seeds and Peers:

SEEDS="9dfa5f2d19c1174baf5e597965394269e654f9b7@seed31.innovationtheory.com:26656"
PEERS="bb761c984bd990f3055f412917396754cd22af7a@validator31.innovationtheory.com:26656,81e36f94351d47803b8e1e0d0ad2d2e8e14ed36b@validator32.innovationtheory.com:26656"
sed -i -e "/^\[p2p\]/,/^\[/{s/^[[:space:]]*seeds *=.*/seeds = \"$SEEDS\"/}" \
       -e "/^\[p2p\]/,/^\[/{s/^[[:space:]]*persistent_peers *=.*/persistent_peers = \"$PEERS\"/}" $HOME/.arkeo/config/config.toml

Configure Node Service

Create the service file:

sudo tee /etc/systemd/system/arkeo.service > /dev/null <<EOF
[Unit]
Description=Arkeo node
After=network-online.target
[Service]
User=$USER
WorkingDirectory=$HOME/.arkeo
ExecStart= $(which arkeod) start --home $HOME/.arkeo
Restart=on-failure
RestartSec=5
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

Reset the node:

arkeod tendermint unsafe-reset-all --home $HOME/.arkeo --keep-addr-book

Start and Enable the Service

Reload and start the service:

sudo systemctl daemon-reload
sudo systemctl enable arkeo
sudo systemctl restart arkeo && sudo journalctl -fu arkeo
