Example Docker Compose configuration:

version: "3.9"
services:
  hysteria:
    image: tobyxdd/hysteria
    container_name: hysteria
    restart: always
    network_mode: "host"
    volumes:
      - ./hysteria.yaml:/etc/hysteria.yaml
    command: ["server", "-c", "/etc/hysteria.yaml"]

Configuration

Proper configuration is essential to harness the full potential of Hysteria2. Configuration files are written in YAML format and allow extensive customization to meet specific networking needs.

Server Configuration

The server configuration file (config.yaml) dictates how the Hysteria2 server operates. Key parameters include:

Listening Address and Port: Defines where the server listens for incoming connections.
Authentication: Configures user authentication methods to ensure secure access.
QUIC Parameters: Fine-tunes QUIC protocol settings for optimal performance.
Traffic Control: Manages bandwidth limits, access control lists (ACLs), and traffic statistics.

For a comprehensive list of server configuration options, refer to the Full Server Configuration Guide.

Client Configuration

The client configuration file specifies how clients connect to the Hysteria2 server. Essential parameters include:

Server Address: The IP or domain name of the Hysteria2 server.
Authentication: Credentials required to connect securely.
Proxy Mode: Determines the operational mode, such as SOCKS5 proxy, HTTP proxy, or others.

Detailed client configuration options can be found in the Full Client Configuration Guide.

Advanced Features

Hysteria2 incorporates several advanced features that enhance its functionality and adaptability:

ACME DNS Configuration

Automatic certificate management using ACME (e.g., Let's Encrypt) simplifies obtaining and renewing TLS certificates, ensuring secure connections without manual intervention.

Refer to the ACME DNS Configuration Documentation for detailed instructions.

Traffic Statistics API

The Traffic Statistics API allows administrators to monitor usage and performance metrics, providing valuable insights for managing network resources effectively.

Explore the Traffic Statistics API Documentation for more information.

Port Hopping

Port hopping dynamically changes the server’s listening port, making it challenging for censors to detect or block Hysteria2 traffic, thereby enhancing censorship resistance.

Detailed guidance is available in the Port Hopping Documentation.

TProxy Mode

TProxy Mode enables transparent proxying at the kernel level on Linux systems, allowing seamless traffic redirection without requiring client-side configuration.

Refer to the TProxy Mode Documentation for setup instructions.

Troubleshooting

While Hysteria2 is designed for reliability, users may encounter issues during setup or operation. The official documentation provides a comprehensive troubleshooting guide to address common problems.

Common Issues and Solutions

Client Not Connecting to Server: Ensure the server is running and accessible. Check firewall settings and verify that the server's listening port is open.
TLS/ACME Issues: Verify DNS records are correctly configured and the ACME client can communicate with the certificate authority.
Performance Degradation: Adjust QUIC parameters and congestion control settings to better align with current network conditions.
