# Tron Node / DONE

### Tron Node reconfiguring:

{% hint style="warning" %}
The documentation is described for installation on a pure VDS without any third-party software or other programmes, please take this into account when installing.
{% endhint %}

1. Install the necessary packages:

   ```shell
   apt update && apt install -y git wget curl nano
   ```
2. Install Docker according to the official documentation<https://docs.docker.com/engine/install/#server>
3. Clone the repository with the docker image:

   ```bash
   git clone https://github.com/boxexchanger/docker-java-tron.git
   ```
4. Go to the directory with the project

   ```
   cd docker-java-tron/
   ```
5. Create a configuration file and set the required contract addresses and event tops: (not obligatory, but recommended so as not to process unnecessary transactions).

   ```bash
   nano ~/docker-java-tron/tron.conf
   ```

   configuration example for processing only USDT events

   ```
   EVENT_PLUGIN_ADDRESS_FILTER=TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t
   ```
6. Create a folder for this node

   ```bash
   mkdir -p ~/docker-java-tron/data/node
   ```
7. Download Lite version of node data from open source[(http://34.143.247.77/](http://34.143.247.77/)) ([documentation](https://developers.tron.network/docs/main-net-database-snapshots#lite-fullnode-data-snapshot))

   ```bash
   wget http://34.143.247.77/backup20240809/LiteFullNode_output-directory.tgz -O ~/LiteFullNode_output-directory.tgz
   ```
8. Unzip the archive (folder`output-directory)` в `~/docker-java-tron/data/node/`

   ```bash
   tar xvf ~/LiteFullNode_output-directory.tgz -C ~/docker-java-tron/data/node/ --strip-components=1
   ```
9. Delete the archive with the Lite data

   ```
   rm ~/LiteFullNode_output-directory.tgz
   ```

   Now our Tron node is ready to go live

### Launch Node

1. Go to the project directory:

   ```bash
   cd ~/docker-java-tron/
   ```
2. Launch Tron node

   ```
   ./start.sh
   ```

### How to add another contract address

1. You have to go into the configuration:

   ```
   nano ~/docker-java-tron/tron.conf
   ```
2. Add another address to the `EVENT_PLUGIN_ADDRESS_FILTER` block by separating the contract addresses with a comma character **, and** do not use line breaks or spaces between addresses.\
   \
   USDT + USDC Example:

   ```
   EVENT_PLUGIN_ADDRESS_FILTER=TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t,TEkxiTehnzSmSe2XqrBj4w32RUN966rdz8
   ```

### Clearing node data:

By default we have set 5 days of data storage which you can synchronise

If you want to change this parameter you need to add a different number of days to your configuration

1. You have to go into the configuration

   ```bash
   nano ~/docker-java-tron/tron.conf
   ```
2. Add a line with your value:

   ```
   MONGO_RETENTION_DAYS=5
   ```

### How to get logs from node:

```
docker exec -it tron-node tail -f logs/tron.log
```

### Opening an access port:

Create proxy from ports&#x20;

\- localhost:8080 to port **2080** for EventServer&#x20;

\- localhost:18090 to port **2090** for fullNode&#x20;

\- localhost:18091 to port **2091** for solidityNode

<details>

<summary>Setting up a proxy on caddy</summary>

Installing caddy <https://caddyserver.com/docs/install>&#x20;

Documentation prepared for **Debian 11 and 12**.

```shell
apt install -y debian-keyring debian-archive-keyring apt-transport-https
```

```shell
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
```

```shell
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' |  tee /etc/apt/sources.list.d/caddy-stable.list
```

```shell
apt update
```

```shell
apt install caddy
```

configuring caddy for proxy&#x20;

8080,18090,18091 to ports 2080,2090,2091 for the external network

**Caddyfile will be overwritten completely!**

```
echo -e ':2080 {\n reverse_proxy :8080\n}\n:2090 {\n reverse_proxy :18090\n}\n:2091 {\n reverse_proxy :18091\n}' > /etc/caddy/Caddyfile 
```

launch caddy

```bash
systemctl enable --now caddy
```

or restart if necessary`systemctl restart caddy`

</details>

### Accesses

**EventServer:** `http://ip.host:2080`\
**Node:** `http://ip.host:2090`\
**Solidity:** `http://ip.host:2091`

### How to update a tron-node container.

Update the version in the .env file <https://github.com/tronprotocol/java-tron/releases>

{% code title=".env" %}

```bash
JAVA_TRON_VERSION="GreatVoyage-v4.7.5"
```

{% endcode %}

Rebuild docker and restart the node:

```bash
docker compose build
./start.sh
```
