Qlauncher simplifies the process of sharing your unused computer resources to earn cryptocurrency. This guide provides a detailed walkthrough for installing, configuring, and troubleshooting QLauncher on Linux systems.

QLauncher allows you to contribute your device’s spare storage and bandwidth to the Poseidon Network, earning you passive income in cryptocurrency. By leveraging unused resources, QLauncher transforms your computer into a contributing node on the network. This comprehensive guide will equip you with the knowledge to seamlessly integrate QLauncher into your Linux environment.

How QLauncher Works: A Deep Dive

QLauncher seamlessly integrates your device with the Poseidon Network, allowing for efficient resource allocation and management.

The system operates through a coordinated interplay of key components:

Poseidon Kubernetes Cluster: This central hub orchestrates the collection and distribution of device resources, including storage, bandwidth, and CPU power.
System Analyzer: Continuously monitors and analyzes the resources shared by your device, ensuring optimal performance.
Lifecycle Manager: Oversees the health and functionality of your device, ensuring smooth and uninterrupted operation.
OTA (Over-the-Air) Updates: Facilitates seamless and effortless updates to QLauncher, keeping your system current.

Preparing Your Linux System for QLauncher

Before diving into the installation process, ensuring your system meets the necessary requirements is crucial.

Hardware Recommendations

For optimal performance, the following hardware specifications are recommended:

Processor: 4 dedicated cores (x86-64bit) for each node service.
RAM: Minimum 8GB.
Storage: Minimum 1TB with no upper limit.
Bandwidth: Minimum 40Mbps upstream and downstream.

System Requirements and Prerequisites

QLauncher is designed for Linux-based operating systems, with Ubuntu (20.04 Desktop/Server preferred) being the recommended distribution. Ensure your kernel version is above 5. Docker must be installed prior to QLauncher installation. QLauncher installed within a Docker container is not supported. Raspberry Pi 4 users should refer to the dedicated preparation guide.

Essential Network Configuration: Port Forwarding

Proper port forwarding is vital for seamless communication within the Poseidon Network. Configure ports 32440 through 32449 and verify their accessibility using a port scanner. For detailed instructions, consult the port configuration guide.

Removing Previous QLauncher Installations

To prevent conflicts, uninstall any older versions of QLauncher before proceeding. Note that reinstalling QLauncher might impact your mining rewards (see issue #41). Refer to the provided uninstall commands for different QLauncher versions.

Installing QLauncher on Linux: A Step-by-Step Guide

With preparations complete, follow these steps to install QLauncher:

Step 1: Installation and Storage Allocation

Execute the following command in your terminal:

sudo su sh -c "$(curl -sfL https://get.qlauncher.poseidon.network/install-v3.sh)"

After installation, specify the amount of storage you wish to contribute to the network.

Step 2: Verification and Status Check

Confirm successful installation by verifying the following:

QLauncher Running Status: Use sudo systemctl status qlauncher to confirm “active (running)” status.
QLauncher Information: Execute sudo /opt/qlauncherV3/qlauncher check to retrieve relevant information.
Container Status: Use /opt/qlauncherV3/qlauncher status to ensure all containers are running correctly.

Step 3: Binding QLauncher to QQQ App

Generate a QR code for linking your device to the QQQ app:

/opt/qlauncherV3/qlauncher bind

Scan the QR code with your QQQ app to complete the binding process. Successful integration will display your device within the app.

Troubleshooting QLauncher Installation

Encountering issues? Try these solutions:

Restart QLauncher: Use sudo systemctl restart qlauncher.
Uninstall and Reinstall: Follow the uninstall instructions for your QLauncher version and reinstall.

Managing QLauncher Operation

To temporarily halt QLauncher, execute /opt/qlauncherV3/qlauncher stop. To resume operation, use sudo systemctl restart qlauncher. Always verify the running status after restarting.
