  • How To Install New Relic Infrastructure Agent in Linux System

    Using a tool to monitor device status and conditions is not new stuff to learn. The only limitation of the conventional PC monitoring tools is, they only monitor what is on the policy, whereas the New Relic Infrastructure monitors the deep down structures, log analysis, and parameters. It measures dynamic host data, live data for both hardware-level and software level parameters. It can notify you before any components are gone broke. You can monitor every layer of your application and optimize performance. Deploying the Relic infrastructure agent is easy and straightforward for any Linux, Mac, and Windows.

  • Install Docker CE on AWS EC2 (Amazon Linux 2) to run containers

    Docker Engine can be installed easily on Amazon Linux 2 running on AWS Ec2 Instance using Yum package manager. If you don’t know how? Then here are the steps to follow.

    Well, being a command-line operating system running on expensive cloud computing services, we need some virtualize platform with lightweight. And what would be better than Docker? There are lots of benefits of using applications virtualized via containers. It improves security and easier management of the software on the server: If an application is hacked, the attacker can only manipulate the container – not the other virtualized applications on the system.

    Furthermore, due to hundreds of pre-built Docker images, it is easy to install any OS or app instantly. In addition, adjustments to a container operating system can be implemented without affecting other applications on the server – this also makes development easier. The container format also makes it easier for applications to move between servers, as they each have the right software environment.

  • Working with Foreground and Background Processes in Linux

    Any program that is running in the system is called a process.

    When we start an operating system, be it Windows or Linux, some programs are started by default.

    In a Linux environment, each process is assigned a process ID or PID, used for many purposes, such as killing a process.

    A process can be running in the foreground, or it could be running in the background.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
