## 🛠️Manual Installation <a href="#install-binary" id="install-binary"></a>

This guide is created under the assumption you are using Ubuntu 22.04 LTS\
If you use other OS, please modify the commands accordingly

### Set environment

```sh
export INSTALLATION_DIR=${HOME}/empe-chain
export DAEMON_NAME=emped
export DAEMON_HOME=${HOME}/.empe-chain
export SERVICE_NAME=emped
export MONIKER="YOUR_NODE_NAME_HERE"
export WALLET="YOUR_WALLET_NAME_HERE"
```

DAEMON\_HOME is the default path, you customize it as you wish

### Write env to .profile

{% code fullWidth="false" %}

```bash
echo 'export DAEMON_NAME=${DAEMON_NAME}' >> ~/.profile
echo 'export DAEMON_HOME=${DAEMON_HOME}' >> ~/.profile
echo 'export DAEMON_ALLOW_DOWNLOAD_BINARIES=true' >> ~/.profile
echo 'export DAEMON_RESTART_AFTER_UPGRADE=true' >> ~/.profile
echo 'export DAEMON_LOG_BUFFER_SIZE=512' >> ~/.profile
echo 'export WALLET=${WALLET}' >> ~/.profile

source ~/.profile
```

{% endcode %}

{% hint style="info" %}
This step is optional, but we recommend you to do it for convenience
{% endhint %}

### Install dependencies

Please refer to [server-preparation](https://docs.cryptonode.id/en/basics/server-preparation "mention")

### Prepare installation

```sh
mkdir -p ${INSTALLATION_DIR}/bin
mkdir -p ${DAEMON_HOME}/cosmovisor/genesis/bin
mkdir -p ${DAEMON_HOME}/cosmovisor/upgrades
```

### Install and Setup Empeiria Daemon

{% code overflow="wrap" %}

```sh
cd ${INSTALLATION_DIR}

#Download Empe Daemon and basic setup
wget -qO - https://github.com/empe-io/empe-chain-releases/raw/master/v0.1.0/emped_linux_amd64.tar.gz | tar -xzf -
mv ${DAEMON_NAME} ${INSTALLATION_DIR}/bin

#Download and install cosmovisor
wget https://github.com/cosmos/cosmos-sdk/releases/download/cosmovisor%2Fv1.5.0/cosmovisor-v1.5.0-linux-amd64.tar.gz
tar -xvzf cosmovisor-v1.5.0-linux-amd64.tar.gz

#Copy Binaries
cp cosmovisor ${INSTALLATION_DIR}/bin/cosmovisor
cp ${INSTALLATION_DIR}/bin/${DAEMON_NAME} ${DAEMON_HOME}/cosmovisor/genesis/bin
sudo ln -s ${INSTALLATION_DIR}/bin/cosmovisor /usr/local/bin/cosmovisor -f
sudo ln -s ${DAEMON_HOME}/cosmovisor/genesis ${DAEMON_HOME}/cosmovisor/current -f
sudo ln -s ${DAEMON_HOME}/cosmovisor/current/bin/${DAEMON_NAME} /usr/local/bin/${DAEMON_NAME} -f
```

{% endcode %}

#### Check emped version

```sh
emped --home ${DAEMON_HOME} version
```

### Download genesis.json

```sh
wget https://snapshot.cryptonode.id/empe-testnet/genesis.json -O ${DAEMON_HOME}/config/genesis.json
```

### Create or Restore Wallet

```sh
#If you want to create new wallet
emped --home ${DAEMON_HOME} keys add ${WALLET}
```

```sh
#If you already have wallet and want to use same phrase
emped --home ${DAEMON_HOME} keys add ${WALLET} --recover
```

{% hint style="info" %}
You will be prompted to "Enter your bip39 mnemonic", paste your phrase and press \[ENTER]
{% endhint %}

#### Check your wallet

```sh
emped --home ${DAEMON_HOME} keys list
```

### Setup pruning config

```sh
sed -i \
  -e 's|^pruning *=.*|pruning = "custom"|' \
  -e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \
  -e 's|^pruning-keep-every *=.*|pruning-keep-every = "0"|' \
  -e 's|^pruning-interval *=.*|pruning-interval = "10"|' \
  ${DAEMON_HOME}/config/app.toml
```

{% hint style="info" %}
The number shown only for reference. \
You can change the number for each parameter as you want
{% endhint %}

### Setting minimum gas fee

```sh
sed -i 's/minimum-gas-prices *=.*/minimum-gas-prices = "0.0001uempe"/' ${DAEMON_HOME}/config/app.toml
```

### Setting up Cosmovisor

```bash
sudo tee /etc/systemd/system/emped.service > /dev/null <<EOF  
[Unit]
Description=Empeiria Testnet Daemon (cosmovisor)
After=network-online.target

[Service]
User=$USER
ExecStart=$(which cosmovisor) run start --home ${DAEMON_HOME}
Restart=always
RestartSec=3
LimitNOFILE=4096
Environment="DAEMON_NAME=${DAEMON_NAME}"
Environment="DAEMON_HOME=${DAEMON_HOME}"
Environment="DAEMON_ALLOW_DOWNLOAD_BINARIES=true"
Environment="DAEMON_RESTART_AFTER_UPGRADE=true"
Environment="DAEMON_LOG_BUFFER_SIZE=512"

[Install]
WantedBy=multi-user.target
EOF
```

#### Enable the service

```bash
sudo systemctl daemon-reload
sudo systemctl enable emped.service
sudo systemctl start emped.service
```

#### Check service log

```bash
sudo journalctl -xfu emped
```

### Cleanup

```bash
rm -f cosmovisor-v1.5.0-linux-amd64.tar.gz
rm -f README.md CHANGELOG.md LICENSE readme.md cosmovisor
```
