  • Full Disk Encryption, without LVM, by default - Call for comments

    Historically Desktop / Server, only configured LUKS full disk encryption with an LVM layer. Thus ones root ext4 filesystem was an LVM volume, on an VG group, on LUKS, on a GPT partition.

    The upcoming Ubuntu Core 20 has full disk encryption with TPM support. In that configuration ext4 filesystem is created directly on the LUKS volume which is directly on a GPT partitition.

    For the upcoming HH 21.04 release, I want to change Desktop/Server, to also install in a similar fashion. Specifically such that by default, we simply use ext4+LUKS without LVM.

    It seems to me that despite having LVM layer, it’s not actually used or appreciated much.

    Would you be ok with having full-disk encryption without LVM by default?

  • Ubuntu 21.04 Installer Might Allow EXT4 Encryption Without LVM - Phoronix

    An early proposal by Ubuntu/Canonical developer Dimitri John Ledkov is proposing full disk encryption by default without LVM. With Ubuntu Core 20 there is going to be support for TPM-backed full disk encryption created directly on the LUKS volume and in turn directly on a GPT partition without LVM. For Ubuntu 21.04, the developers are looking at changing the Ubuntu desktop/server installers to potentially allow similar EXT4 encryption directly atop LUKS without LVM.

  • 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.
