Server Engineering Practices





This repository contains the server engineering practices completed as part of the course requirements in Computer Engineering at the University of Granada. Each practice focuses on different server management tools and techniques, with instructions provided for each setup.

Practice 3: RAID, Zabbix, and Ansible Setup

1. RAID Disk Monitoring and Reconstruction

  • Objective: Identify, monitor, and reconstruct a RAID disk on Ubuntu.
  • Process:
    • Use cat /proc/mdstat to check RAID status.
    • Hot-unplug one disk to simulate a failure and verify it with lsblk.
    • Add a new disk and configure it with fdisk, install GRUB, and add the partitions to RAID with mdadm.

2. Zabbix Installation and Configuration

  • Objective: Install and configure Zabbix on Ubuntu and Rocky Linux for monitoring SSH and HTTP.
  • Steps:
    • Install Zabbix, MariaDB, and configure databases.
    • Configure zabbix_server.conf, zabbix_agentd.conf, and set up firewall ports.
    • Monitor HTTP and SSH by configuring host items in the Zabbix web interface.

3. Ansible Installation and Basic Command Execution

  • Objective: Use Ansible to manage virtual machines.
  • Steps:
    • Install Ansible and set up the /etc/ansible/hosts file.
    • Execute basic commands, such as ls /home, across all machines.
    • Run scripts like mon-raid.py on multiple machines.

4. Timer Service Activation

  • Objective: Automate RAID monitoring with a timer service.
  • Steps:
    • Configure mon_raid.service and mon_raid.timer in /etc/systemd/system/.
    • Start the timer with systemctl start mon-raid.timer and check status with journalctl.

Practice 4: Phoronix and JMeter Benchmarking

1. Phoronix Benchmark on Ubuntu and Rocky

  • Objective: Compare the performance of Ubuntu and Rocky Linux using Phoronix.
  • Steps:
    • Install Phoronix on each system.
    • Run pts/sudokut and pts/pybench benchmarks to test system and CPU performance.
    • Results: Ubuntu displayed slightly faster processing times compared to Rocky.

2. JMeter Testing on Docker Containers

  • Objective: Perform load testing on a web application deployed with Docker containers.
  • Steps:
    • Set up Docker and Docker Compose to deploy the application.
    • Create a JMeter test plan with different thread groups for students and administrators.
    • Configure CSV data, random timers, and HTTP header managers for authentication and data retrieval.

Requirements

  • Ubuntu and Rocky Linux virtual machines
  • Zabbix, Ansible, Docker, JMeter, and Phoronix

Installation and Setup

Refer to each section above for detailed setup instructions, configurations, and troubleshooting tips.

Troubleshooting

  • Zabbix: Ensure MariaDB is correctly installed and configured before proceeding with Zabbix setup.
  • Ansible: Use SSH key authentication between machines to avoid connection issues.
  • JMeter: Verify Docker containers are running and accessible on the specified ports.

  Smart Microphone with Sound Source Localization  h ttps://github.com/diegodl11/Smart-Microphones.git Explanation This project aims to design a  smart microphone  with the capability of  sound source localization . The system is composed of an array of multiple microphones that, through algorithms and signal processing, allows for highly precise determination of the location of a sound within an environment. Main Objective: The goal is to overcome the limitations of traditional sound localization methods by improving precision and sensitivity through an innovative and efficient system. An  Arduino microcontroller  is used for central processing, along with three microphones to capture sounds from different points and triangulate the position of the sound source. Key Components: Arduino  as the control unit. Three microphones  to capture sound waves and determine the location of the source using geometry. Bluetooth module  for wireless c...

  Multispectral Imaging in MATLAB https://github.com/diegodl11/Multispectral-Imaging-.git Introduction This project focuses on implementing and visualizing multispectral imaging techniques using MATLAB. Multispectral imaging captures information from multiple wavelengths across the electromagnetic spectrum, unlike traditional RGB images that capture only three bands. These images can be used for applications in agriculture, medical imaging, and remote sensing, among other fields. Project Overview This project uses MATLAB to load, process, and visualize multispectral images from different bands. It implements techniques for image filtering, contrast enhancement, and visual inspection of various bands, allowing users to observe features like vegetation health, water presence, and more. Prerequisites MATLAB installed with the Image Processing Toolbox. A multispectral image file (preferably in  .tif  format with multiple bands). How to Run the Code Load the Image : The path t...
