  • Steinar H. Gunderson - Speeding up Samba AD

    One Weird Trick(TM) for speeding up a slow Samba Active Directory domain controller is seemingly to leave and rejoin the domain. (If you don't have another domain controller, you'll need to join one in temporarily.) Seemingly, not only can you switch to LMDB (which has two fsyncs instead of eight on commit—which matters a lot, especially on non-SSDs, as the Kerberos authentication path has a blocking write to update account statistics), but you also get to regenerate the database, giving you the advantage of any new indexes since last upgrade.

  • How to Change File Extensions on Linux

    File extensions help both operating systems and users distinguish between different file formats and understand the contents stored inside them. When you see a file with the ".txt" extension, you instantly know it contains text data. Similarly, ".exe" file is a Windows executable and ".sh" files are Linux shell scripts.

    But what if you want to change these extensions for some reason? Perhaps you need to rename a text file to a Bash script. Simply writing the code in a text file won't do the job.

    On Linux, changing file extensions is much easier than you might think.

  • 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.
