TRON Lite Full Node Deployment Script

Description

This script is designed for automatic deployment of a TRON Lite Full Node on Ubuntu/Debian servers. The script performs the following operations:

1. Installation of necessary dependencies
2. Configuration of Java 8 as the main version
3. Cloning and building the java-tron repository
4. Automatic search and download of the latest available database archive for quick start
5. Creation of all configuration files
6. Setup of autostart via systemd
7. Starting the node

Requirements

• Ubuntu 20.04/22.04 or Debian 10/11
• Minimum 32 GB RAM (64 GB recommended, 128 GB best perfomance)
• Minimum 500 GB disk space (SSD or NVMe recommended)
• Root privileges for installation

Troubleshooting

Java Version Issues

If you encounter issues with the Java version, you can manually configure Java 8:

sudo update-alternatives --config java
# Select the option with java-8-openjdk

sudo update-alternatives --config javac
# Select the option with java-8-openjdk

Java-tron Compilation Issues

If you encounter errors during compilation related to the missing javax.annotation.Generated class, add the following dependency to the build.gradle file:

dependencies {
    implementation 'javax.annotation:javax.annotation-api:1.3.2'
}

Database Archive Download Issues

If the script fails to automatically find or download the latest database archive, you can:

1. Manually check available backups:

curl -s http://34.86.86.229/ | grep -o 'backup[0-9]\{8\}'

2. Download the archive manually using the latest available backup (replace XXXXXXXX with the actual date):

wget http://34.86.86.229/backupXXXXXXXX/LiteFullNode_output-directory.tgz -O /tmp/LiteFullNode_output-directory.tgz
mkdir -p /home/java-tron/output-directory
tar -xzf /tmp/LiteFullNode_output-directory.tgz -C /home/java-tron/output-directory

Node Update

To update the node to the latest version:

cd /home/java-tron
git pull
./gradlew clean build -x test
systemctl restart tron-node
