  • Linux 101: What is the SUID permission? - TechRepublic

    If you're new to Linux administration, you've probably already started learning about file permissions. If I said "drwxrwxr-x," you'd know what that meant. It's simple: A directory with owner and group read, write, execute permissions, but only read and execute permissions for everyone else.

    That's not the be-all, end all for permissions. There are actually three more permissions, one of which I'm going to teach you about right now. Said permission is called SUID, which stands for Set owner User ID. This is a special permission that applies to scripts or applications. If the SUID bit is set, when the command is run, it's effective UID becomes that of the owner of the file, instead of the user running it.

  • What is the Vim Editor in linux?

    If you are working in the command line mode, you may need to become familiar with a text editor that will be operating in a Linux console. The vim editor is the original editor that Unix uses. It makes use of the console graphics mode for the emulation of a text-editing window, which allows you to see different lines of the file, move around across the files, and edit, insert or replace a piece of text. The vim editor works well with the data that is in a memory buffer. You have to type vim and the name of the file that you have to edit to open the editor with the desired file.

    If the editor is started without a filename being supplied, it opens but with no file. The vim editor detects the session’s terminal type and uses full-screen mode so the console window can use the editor area. The initial window will show the file contents and a message line at the bottom of the window. If the contents don’t take up the entire screen, a tilde is placed on the lines excluded from the file. The vim editor has two operational modes — normal and INSERT mode. When you open a file for editing, vim goes into normal mode, and certain keystrokes are interpreted as commands.

  • 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.
