💻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="1.20.3"
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/arkeonetwork/arkeo && cd arkeo
git checkout master
TAG=testnet make install

arkeod version --long | grep -e version -e commit
# version: v1.0.0-prerelease
# commit: 51e568dd1cff1af6249fa3b4806ccd5573249ae2

We initialize the node to create the necessary configuration files

arkeod init UTSA_guide --chain-id arkeo-testnet-3

Download Genesis

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

sha256sum ~/.arkeo/config/genesis.json
# 1e8c6c54bdfa3da1587967806cd9b9092262521e230063a2a4e672b8d390abe7

At this stage, we can download the address book

wget -O $HOME/.arkeo/config/addrbook.json "https://share101.utsa.tech/arkeo/addrbook.json"

Set up node configuration

arkeod config set client chain-id arkeo-testnet-3
arkeod config set client keyring-backend os
sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.001uarkeo\"/;" ~/.arkeo/config/app.toml

# seeds/peers
external_address=$(wget -qO- eth0.me)
sed -i.bak -e "s/^external_address *=.*/external_address = \"$external_address:26656\"/" $HOME/.arkeo/config/config.toml
peers="[e-mail]:26656,[e-mail]:26656"
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.arkeo/config/config.toml
seeds="[e-mail]:26656"
sed -i.bak -e "s/^seeds =.*/seeds = \"$seeds\"/" $HOME/.arkeo/config/config.toml

sed -i -e "s/^filter_peers *=.*/filter_peers = \"true\"/" $HOME/.arkeo/config/config.toml

(OPTIONAL) Set up pruning

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

(OPTIONAL) Set up indexer

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

(OPTIONAL) Enable/Disable Snapshots

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

Create a service file

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

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

[Install]
WantedBy=multi-user.target
EOF

systemctl daemon-reload
systemctl enable arkeod
systemctl restart arkeod && journalctl -u arkeod -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
