To uninstall a package, you need to reference yum, followed by remove than the package name. Like installing a package, uninstalling one is also incredibly simple. yum install git Using yum to Uninstall Packages yum install PACKAGENAMEįor example, if we wanted to use yum to install git, you would run the following command. Installing a package using yum is a very simple process.Īll we need to do is reference yum followed by install, then the package name. Installing Packages from the Repository with yum Just like with apt, you can use this to install, update, and uninstall packages. Yum is a package management tool that is very similar to apt. Unlike Raspberry Pi OS, which uses the apt package manager, CentOS makes use of yum. In our next section, we will quickly walk you through installing packages using CentOS’s package manager. You should now have the minimal version of CentOS up and running on your Raspberry Pi. Make sure you set the password to something secure as the root user has full access to all parts of the operating system.ģ. To change the password for the root user, you can use the following command. We highly recommend that you change this password once you have logged in.Ģ. The default password for the root user is centos. The default user on your new CentOS installation is root. ![]() With Etcher opened on your device, click the “ Select image” button.Ĭlicking this button will bring up a file dialog box that will allow you to select the CentOS image that you want to write. To write the image to the SD card, we will be making use of the BalenaEtcher software.ġ. In this section of the guide, we will show you how to write the CentOS image to your Raspberry Pi’s SD card. Once you have a copy of CentOS 7 downloaded to your device, we can now write it to an SD Card. This file will be noted by the text minimal in it, for example, CentOS-Userland-7-armv7hl-RaspberryPI- .ģ. The minimal version of the OS does not feature a desktop interface, so it is best for those familiar with navigating an OS using the terminal. This iso file will be named something like “ CentOS-Userland-7-armv7hl-RaspberryPI- “.Īlternatively, you can download the minimal version of Centos 7 for the Raspberry Pi. You can download Centos 7 for the Raspberry Pi that contains the GNOME desktop interface. If you are running a Raspberry Pi 3, then you have a few more choices in what version of CentOS that you can download. Other builds will not function on the Pi 4. This text indicates that it has support for the Raspberry Pi 4’s hardware. On the mirror page, you need to find the minimal version of CentOS that contains the number 4 in its filename.įor example, the filename CentOS-Userland-7-armv7hl-RaspberryPI- contains the phrase “ Minimal-4” within it. Sadly for the Raspberry Pi 4, you will have a limited choice on what version of CentOS that you can use. The Pi 4 only has access to the minimal version of CentOS. ![]() The first choice you need to make is depending on what Raspberry Pi you are using. Once you are on a CentOS mirror website, you will have a couple of choices to make. However, the one at the top is typically the best mirror for your region.Ģ. On this page you will find a list of CentOS mirrors, you can use any of these. To download CentOS for our Raspberry Pi, we will need to go to the official CentoOS website. In this section, we will show you where you can download the official releases for CentOS on the Raspberry Pi.ġ. For the Raspberry Pi 3B+, we were running CentOS with the GNOME desktop interface. We tested this tutorial on a Raspberry Pi 4 and a Raspberry Pi 3B+.įor the Raspberry Pi 4, we were running the minimal version of CentOS. Equipmentīelow is the equipment that we used to install CentOS on to the Raspberry Pi. This allows you to maintain longer uptimes without worrying about packages becoming no longer supported as security and bug fixes are commonly backported. The long term support means you can continually run the same operating system for an extended period without having to do a full upgrade. ![]() For instance, CentOS 7 was released in 2014 but will have continued support until at least 2024. One of the reasons for this is that each release has a very long support schedule. It is the free and open-source version of its upstream source, Red Hat Enterprise Linux.ĬentOS is one of the most used operating systems for web hosting. CentOS is a Linux distribution that provides a free, community-supported operating system.
