Implement Service and Packaging for New Wazuh Agent

Parent Issue:

• Agent/server communication protocol wazuh#22677

Description

As part of the ongoing development of the new Wazuh agent, we need to ensure that the agent can be installed on the host system and run as a background service, utilizing the system's built-in tools (packaging managers, Systemd, etc.). This issue aims to implement the following key components:

1. Ensure the agent can run as a background service (daemon).
2. Develop system services for the agent to run on Linux, Windows, and macOS.
3. Implement standard package management (RPM, DEB, PKG, MSI) for agent installation.

Functional Requirements

• The agent should run as a background process (daemon) across supported systems.
• The system must offer the capability to start, stop, and restart the agent manually. The default behavior (enabled/disabled) depends on the standard defined by the underlying platform.
• The agent should be installable via appropriate package management systems:
  • Linux:
    • RPM for RHEL-based distributions.
    • DEB for Debian-based distributions.
  • Windows: MSI installer.
  • macOS: PKG installer.

Non-Functional Requirements

• The installation packages should follow the conventions and standards of the target operating systems.
• The installation process should be as seamless as possible, reducing manual configuration steps.
• Clear logging of agent activities must be available to facilitate troubleshooting.

Implementation Restrictions

• The service for Linux must use systemd as the service manager since it is widely supported across the listed distributions.
• Packaging must integrate with native package managers (e.g., rpm, apt, install, msiexec) and conform to the relevant package guidelines for each platform.

Plan

• Implement Wazuh Agent Daemon Mode #140
  • Develop and test the agent's ability to start and run in the background independently on each platform.
• Develop Service for Wazuh Agent #127
  • Create Systemd Service for Linux #130
  • Implement Windows Service for Wazuh Agent #131
  • Develop Launch Daemon for macOS #132
• Create Installation Packages for Wazuh Agent #128
  • Create RPM and DEB packages for Linux distributions.
  • Develop an MSI installer for Windows.
  • Develop a PKG installer for macOS.
• Develop GitHub Actions Workflows for Building Wazuh Agent Packages #129
  • Set up testing pipelines for each platform to ensure proper installation and service functionality.
  • Validate installation, service startup, and basic operation on all supported platforms.
• Documentation:
  • Create installation and service management documentation for system administrators.
  • Provide instructions for package installation, service control, and troubleshooting.
