In Linux systems, memory management is crucial for maintaining system stability and performance. One component at the heart of this process is the "Out-Of-Memory (OOM) Killer." This process steps in when your system is critically low on memory. It selectively terminates one or more processes to free up memory and prevent a system crash. However, the intervention of the OOM Killer can be disruptive, as it might terminate essential or high-priority processes.

I recently acquired two budget-friendly Virtual Private Servers (VPS) from OranMe, one featuring a 0.1 CPU with 128MB RAM and the other a 0.5 CPU with 512MB RAM. These low-spec servers are not ideal for heavy usage but can be efficient for specific tasks. To maximize their performance, I chose Debian without a desktop environment, aiming to reduce system load.

Nginx is a high-performance web server known for its efficiency, especially in terms of memory usage, fast startup times, and handling high concurrency. This makes it a popular choice for various internet projects.

This compilation is designed to be a handy reference for common Linux commands, helping both new and seasoned users navigate various system tasks with ease.

Docker revolutionizes the way we think about software deployment with its innovative platform-as-a-service (PaaS) model. Utilizing OS-level virtualization, Docker packages software in lightweight, efficient containers, offering a flexible and portable solution for software deployment.
