  • 10 storage guides for sysadmins heading into 2022 | Enable Sysadmin

    As a sysadmin, nothing is more nerve-wracking than a big data migration, and today's storage technologies have come so far that the process can be complicated. I can certainly remember long nights of storage appliance migrations—or even worse, data recoveries—during my days as a sysadmin.

    Enable Sysadmin's top storage articles of 2021 are packed with advice. If you're looking for information about resizing logical volumes, Shehu Awwal has a great article, "How to resize a logical volume with 5 simple LVM commands." What's the difference between NVMe and M.2? Take a look at Tyler Carrigan's article. Are you moving data around with rsync or FTP? Check out articles from Steve Newsted, Glen Newell, Anthony Critelli, and Tyler. Or maybe backups, encryption, or compression are what you're looking for. Saksham Lamba and Ken Hess have that space covered. You can find links to all of these articles (and more) below.

  • Our top 10 articles of 2021 for IT leaders | The Enterprisers Project

    IT leaders learn new tech terms every year, but in 2021, they learned a new management term: Hybrid work. This way of working combines office and remote work.

    As Jordan Peace wrote in one of our top 10 articles of 2021, “Hybrid work presents some unique challenges for employers: How do you run a meeting when half the team is clustered in a conference room while the others are on Zoom? How do you foster collaboration when some employees may never see each other in person and others are together multiple times per week? And how do you extend the less-obvious benefits of an in-person office — social connection, a shared context with coworkers, and office perks — to those who choose to work from home?”

  • IT careers: 3 misconceptions that hold people back | The Enterprisers Project

    Today’s talent market is experiencing some significant growing pains. We’re witnessing a structural realignment of what it means to work and what careers can look like, with employers and candidates each offering their own unique take on the subject.

    While the specifics vary across industry, experience, and education level, the greatest opportunity for talent re-examination exists within fields that have suffered from longstanding mistaken beliefs.

    IT is a prime example. Reinforced by decades of standard operating procedure and rigid widespread processes, building an IT career has often seemed to mean resigning oneself to one of several predetermined paths. However, today’s unique market conditions are upending traditional workplace assumptions, and now is the time for IT professionals to shed their hindering beliefs and embrace new possibilities.

  • systemd 250 improves credential support and makes it easier to migrate home - itsfoss.net

    systemd 250 it is already among us as the new version of init, framework system or system manager that has established itself as one of the most essential components of the Linux ecosystem, starting with most of the most popular distributions. Once again, we find a very large number of changes and news, which, apart from being complex, cover many areas.

    systemd 250 added support for encrypted and authenticated credentials. This can be a key stored in ‘/ var’ or a TPM2 chip in the system whereby the credentials will be decrypted automatically when the corresponding service starts. On the other hand, a tool called ‘systemd-creds’ has been incorporated to manage credentials and that can be used for SSL certificates, passwords and similar data.

    Specification of GPT partition detection has been extended with support for root (/) and ‘/ usr’ partitions on most systemd supported architectures, while ‘systemd-logind’ has a new setting for long press of the system start, restart and sleep buttons. From now on, if the user wishes, long presses of more than 5 seconds can be configured to logind.

  • 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. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • 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.
