Now he wanted to finish his initial linux learning with one of the most important topics like linux networking and service manager. As devOps is heavily related to networking and service management and linux networking commands and systemctl command are essential for them. After that, he wanted to practice his learning with writing a little script. ...

Other Parts of This Series: Part 8: DevOps - Step By Step Learning : Part 8 (Linux Command for File, Directory and Text Manipulation) Part 10: DevOps - Step By Step Learning : Part 10 (Linux Networking, Compression and Little Scripting for Automation) DevOps Linux Package, User, Process Management (Photo Credit: Unsplash) Story: Rasel already learned commands to manage files, directories, and contents in them without needing any UI and only via CLI. To run an application (maybe frontend, backend, database, or any other program), we need to install many dependencies like other software/applications, packages, or libraries. So Rasel now needs to learn to manage packages via command. Also, for safety, security, and operational purposes, user and permission management is another mission-critical task, so you need to learn this as well. To make operational life easy, efficient, and robust, Linux process and system management is a very important part that should be learned at any cost as a DevOps professional. Rasel wanted to explore all these topics and did so. ...

It’s time to start with the core concepts, like the Linux core component called the Kernel, how it boots, and what the file structure is that Linux holds to manage everything. ...

Other Parts of This Series: Part 5: DevOps - Step By Step Learning : Part 5 (Create a REST API Server Using Golang and Gin) Part 7: DevOps - Step By Step Learning : Part 7 (Understand Linux Kernel, Boot Process and Filesystem Hierarchy) DevOps Linux Knowledge (Photo Credit: Unsplash) Story: Rasel completed step 1, which means now he felt confident programming with Golang. Being a .NET (C#) developer and part-time gamer, he always used the Windows operating system. But in his DevOps learning journey, he needs to learn Linux now. But before starting to learn, he needs to be convinced enough about Linux. It means he needs to know why Linux is important, why it is really needed, what he should learn, and how much Linux knowledge he should know to work in DevOps. So he started searching for all of his questions’ answers. ...
