Ubuntu Server 24.04 LTS brings five years of support, performance boosts in Linux 6.8, and built-in container tools. This guide walks you through every command and menu click—from preparing your USB stick to locking down SSH—so you can deploy a production-ready server with confidence. 1. System Requirements & Preparations CPU: 2 cores @ 2 GHz minimum RAM: 4 GB (8 GB+ recommended) Disk: ≥ 25 GB (SSD preferred) Network: Wired Ethernet adapter Boot Media: USB stick (8 GB+) Secondary Machine: To download ISO and write USB Tip: Enable virtualization (VT-x/AMD-V) in BIOS if you plan VMs. 2. Download & Validate the ISO Download wget https://releases.ubuntu.com/24.04/ubuntu-24.04-live-server-amd64.iso Verify Checksum sha256sum ubuntu-24.04-live-server-amd64.iso Compare against the checksum on releases.ubuntu.com/24.04. 3. Create a Bootable USB...
As a database administrator, I once relied on DELETE to purge large volumes of obsolete records. Over time, I discovered this approach caused hidden performance and storage headaches. In this post, I’ll share what I learned about InnoDB’s storage model, the pitfalls of bulk DELETE, and the best practices I now follow. Understanding InnoDB’s Storage Architecture InnoDB stores data in tablespaces, segments, extents (groups of 32 pages), and pages (16 KB each by default). When you delete rows, InnoDB simply marks them as deleted—it doesn’t return space to the operating system. As a result, the .ibd file stays the same size, leaving unused “holes” in your tablespace. My Experiment: DELETE Doesn’t Free Space I created an empty table and saw...
As the person responsible for our company’s IT infrastructure, one of my essential tasks was optimizing our web servers. After much research, testing, and consideration, Nginx emerged as the optimal solution due to its high performance, reliability, and flexibility. Understanding Nginx Architecture and Working Model One aspect that immediately attracted me to Nginx was its highly efficient architecture. Unlike Apache’s thread-based approach, Nginx uses a Master-Worker architecture. Master and Worker Processes The Master process manages global operations: reading configurations, launching worker processes, and overseeing their health. Each Worker process, operating independently, handles client requests using an event-driven model, efficiently managing multiple connections with minimal resource usage. Event-Driven Asynchronous Model Worker processes employ a non-blocking, event-driven model, ensuring quick request handling...
One day last week, I woke up to a nightmare scenario: our company’s Apache server had slowed to a crawl, and within minutes it was clear we were under a Distributed Denial of Service (DDoS) attack. Having faced this situation before, I knew immediately what I needed to do. Here’s exactly how I handled it, step-by-step, to not only stop the attack but to make sure it wouldn’t happen again. Step 1: Identifying the Attack The first thing I did was to verify that it was indeed a DDoS attack. I logged into our Apache server and checked the server logs using: tail -n 100 /var/log/apache2/access.log I noticed a massive flood of repeated requests from suspicious IP addresses targeting the...
Keeping your Apache server secure doesn’t have to be complicated. As someone who’s managed multiple Apache setups, I’ve learned firsthand how a few simple security steps can drastically improve the safety of your websites and applications. Here’s my quick, human-friendly guide to enhancing your Apache server security: 1. Regularly Update Apache Staying current is critical. Regular updates patch vulnerabilities and improve security. I recommend setting automated updates or reminders to ensure you’re running the latest secure version. 2. Disable Directory Listing Exposed directories are an invitation to attackers. To disable directory browsing, simply add this line in your .htaccess or Apache config: Options -Indexes 3. Implement SSL/TLS SSL/TLS encryption ensures data integrity and security. Using free solutions like Let’s Encrypt...
