Гайд по установке Ojo

Требования к сервру

- 4CPU
- 16RAM
- 200GB

Подготавливаем сервер

sudo apt update
sudo apt install -y curl git jq lz4 build-essential unzip

Устанавливаем Golang

 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$ver.linux-amd64.tar.gz" && \cd
  echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile && \
  source $HOME/.bash_profile

Устанавливаем ноду

git clone https://github.com/ojo-network/ojo
cd ojo 
git checkout v0.1.2
make install

Инициализируем ноду

ojod init <Моникер> --chain-id ojo-devnet

Скачиваем генезис файл

curl -Ls https://rpc.devnet-n0.ojo-devnet.node.ojo.network/genesis > $HOME/.ojo/config/genesis.json

Настраиваем StateSync

SNAP_RPC="https://ojo-testnet.nodejumper.io:443"

LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height)
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000))
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)

echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH

PEERS="17a5fad48064ee3da42f435925f7bbe055e6348d@ojo-testnet.nodejumper.io:37656"
sed -i 's|^persistent_peers *=.*|persistent_peers = "'$PEERS'"|' $HOME/.ojo/config/config.toml

sed -i 's|^enable *=.*|enable = true|' $HOME/.ojo/config/config.toml
sed -i 's|^rpc_servers *=.*|rpc_servers = "'$SNAP_RPC,$SNAP_RPC'"|' $HOME/.ojo/config/config.toml
sed -i 's|^trust_height *=.*|trust_height = '$BLOCK_HEIGHT'|' $HOME/.ojo/config/config.toml
sed -i 's|^trust_hash *=.*|trust_hash = "'$TRUST_HASH'"|' $HOME/.ojo/config/config.toml

Создаем сервисный файл

sudo tee /etc/systemd/system/ojod.service > /dev/null << EOF
[Unit]
Description=Ojo Node
After=network-online.target
[Service]
User=$USER
ExecStart=$(which ojod) start
Restart=on-failure
RestartSec=10
LimitNOFILE=10000

[Install]
WantedBy=multi-user.target
EOF

Запускаем ноду

sudo systemctl daemon-reload
sudo systemctl enable ojod
sudo systemctl start ojod

Проверяем логи

sudo journalctl -fu ojod -o cat
