Introduction If you're working with PHP on a Linux system , knowing the PHP version installed is crucial for compatibility and debugging. Here are four simple methods to check the PHP version on your Linux machine. 1. Using the php -v Command The easiest and most common way to check the PHP version is by using the php -v command in the terminal. This command provides detailed information about the PHP version installed. Steps: Open your terminal. Type php -v and press Enter. You will see output similar to: Copy code PHP 7.4 .3 (cli) (built: May 26 2020 12 : 24 : 05 ) ( NTS ) Copyright (c) The PHP Group Zend Engine v3 .4 .0 , Copyright (c) Zend Technologies 2. Using the php --version Command Another command that yields the same result as php -v is php --version . This command is interchangeable with the previous one and provides the same information. Steps: Open your terminal. Type php --version and press Enter. You will see output similar to the one shown above. 3. Creatin

Retrieving the internal IP address of a Docker container is a common requirement for networking and troubleshooting. In this guide, we'll cover several methods to obtain the internal IP address, ranging from basic to advanced techniques. This information is essential for developers and system administrators who work with Docker containers regularly. Basic Method: Using Docker Inspect The most straightforward way to retrieve a Docker container's internal IP address is by using the docker inspect command. This command provides detailed information about a container, including its IP address. Step-by-Step Guide List Running Containers First, list all running containers to find the container ID or name. Copy code docker ps Inspect the Container Use the docker inspect command followed by the container ID or name to get detailed information. Copy code docker inspect <container_id_or_name> Extract the IP Address The output of the docker inspect command is in JSON format. Loo

Introduction Deploying machine learning (ML) solutions can be a complex process, but with the right tools and knowledge, it can be simplified. This guide will walk you through deploying an ML model using FastAPI, Docker, and Google Cloud Platform (GCP). We’ll cover everything from basic concepts to advanced deployment techniques with example Python code. Why Choose FastAPI, Docker, and GCP for ML Deployment? FastAPI: A modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints. Docker: An open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. Google Cloud Platform (GCP): Provides a suite of cloud computing services that runs on the same infrastructure that Google uses internally for its end-user products. Prerequisites Before we begin, make sure you have the following installed and set up: Python 3.6+ Doc

Introduction Linux systems rely on packages for software distribution, but sometimes these packages can encounter issues and break. This article will guide you through understanding why Linux packages break and how to fix them to ensure your system remains stable and updated. How Does a Linux Package Break? A Linux package might break due to several reasons such as interrupted updates, conflicts between packages, or corrupted package files. Understanding the root cause is crucial for fixing the issue effectively. How to Fix Broken Packages on Linux Fixing broken packages involves a series of steps tailored to different Linux distributions. Here, we'll cover the methods for both Debian-based systems like Ubuntu and RPM-based systems like Fedora and RHEL. Updating Broken Packages on Ubuntu and Debian For Debian-based systems, resolving broken packages can be achieved with the following commands: Update package information and fix missing dependencies: sudo apt update --fix-missing R

Introduction Keeping an eye on who logs into your Linux server is crucial for maintaining the security and integrity of your data. In this guide, we will explore several commands that can help you generate reports on login activities, enhancing your server’s security by spotting potential unauthorized access or other suspicious activities. Why Monitoring Login Activity is Important Monitoring who accesses your server and when is key to identifying potential security breaches and ensuring that only authorized users have access. This process is not only critical for security purposes but also helps in system management by providing insights into user behaviors and system usage patterns. Commands for Checking Login Activity To get started, here are some basic commands that you can use to view login activities on your Linux server: last Description: This command reads the /var/log/wtmp file where system login records are stored. It is useful for reviewing past login sessions. Example Comm

Introduction For Linux administrators and power users, sudo has long been the go-to command for executing operations that require root access. Despite its widespread use, sudo comes with security vulnerabilities and struggles to meet the demands of increasingly complex modern systems. A new tool, run0, steps in as a systemd-based alternative designed to enhance security and simplify privilege management. What is run0? run0 is an innovative utility anchored in the systemd framework, which forms the backbone of many Linux distributions. Contrasting with sudo's setuid-root model that introduces numerous security challenges, run0 utilizes systemd's native capabilities to handle privileges more securely and efficiently. Key Benefits of run0 Over Sudo Enhanced Security: run0 reduces the risks associated with privilege escalation by integrating tightly with systemd’s service management capabilities. This approach limits the scope of operations and the potential for security breaches.
