Preparation

Before setting up a Nukkit server, you need to prepare the necessary environment and tools.

System Requirements​

Running a Nukkit server requires meeting the following basic requirements:

  • Operating System: Windows, Linux, or macOS
  • Java: Nukkit requires Java 21 or higher
  • Memory: At least 1GB RAM (2GB or more recommended)
  • Storage: At least 500MB available space

Installing Java​

Download Java​

  1. Visit the Adoptium website to download Java 21 or higher
  2. Select the installation package suitable for your operating system
  3. Download and run the installer

Verify Installation​

After installation, you need to verify that Java is correctly installed:

# Run in terminal (Linux/macOS) or command prompt (Windows)
java -version

If you see output similar to the following, Java is successfully installed:

openjdk version "21.0.x" 20xx-xx-xx
OpenJDK Runtime Environment Temurin-21.0.x (build ...)
OpenJDK 64-Bit Server VM Temurin-21.0.x (build ...)
