Some of these will vary according to your requirements or preferences. If you need to configure other options, run raspi-config again. Verify that the card's full capacity is being used with the df command: # df -h After taking this option, reboot and log in again. It presents an option to expand the root filesystem to use all of the available space on the microSD card. Run it immediately after logging in: # raspi-config The main configuration program in Raspberry Pi OS is called raspi-config. Always review a product's documentation to ensure you're not applying an outdated configuration. There are often several ways to apply a configuration, and configuration files and directives can be deprecated. I recommend spending time to research each configuration to be as correct as possible. Take the following steps to minimize your installation, disk space, and memory usage as much as possible. Once it boots, log in with the default credentials: user pi and password raspberry. Insert the microSD card and power on the Pi. I also have an Ethernet cable for network connectivity, which I prefer over wireless-especially for a dedicated server. You just need a monitor, keyboard, and power adapter to access the Raspberry Pi. Although there are many graphical image-writing tools available, I used the venerable dd command: # dd bs=4M if=/home/alan/Downloads/raspios/-raspios-buster-armhf-lite.img of=/dev/mmcblk0 status=progress conv=fsync Boot the Pi ![]() Once the partitions are unmounted, write the image file to the microSD card. I then unmounted the partitions with the umount command: # umount /dev/mmcblk0p2 To do so, I had to determine their path with the lsblk command, which identified the device as /dev/mmcblk0: # lsblk -p I couldn't write the image until I unmounted these partitions. My card was used previously, and when I inserted it into my Linux desktop, it automatically mounted its two existing partitions. The second step is to write the downloaded OS image file to the microSD card. I do not expect any major differences, but as always, I recommend reading the release notes.) Write the OS to the microSD Card (When I downloaded the OS, the release date was August 20, 2020, but it has been updated since then. It is the smallest OS and includes only the essential files required for a base OS, so it will consume the least amount of disk space and system RAM. Three different images are offered, and I chose the Raspberry Pi OS Lite. The first step is to download the newest OS image file from the official Raspberry Pi OS site to a computer you can use to write to a microSD card. Whitepaper: Data-intensive intelligent applications in a hybrid cloud blueprint.eBook: Running Kubernetes on your Raspberry Pi.Getting started with Raspberry Pi cheat sheet.While several operating systems are available, I chose to stick to the officially supported OS. This requires two things: an OS image file and a microSD card. To begin, create a new operating system drive for the Pi. This step-by-step guide shows how I set up my Raspberry Pi with the most minimal configuration to conserve precious system resources. I think my original installation used the full operating system image that includes the graphical user interface and a lot of other software packages unnecessary for my needs. ![]() So I acquired a new microSD card and preceded to rebuild.Īlthough this Raspberry Pi 3 Model B isn't the latest hardware, it is still adequate for running a minimal server for various services. After its initial installation, it began experiencing disk problems and the official Raspberry Pi operating system (OS) received a significant update (and was renamed from Raspbian to Raspberry Pi OS). ![]() ![]() It had been in constant use as a server for almost two years, and this provided a good opportunity to start fresh and correct a few problems. Recently, the microSD (secure digital) card in my Raspberry Pi stopped working.
