![]() ![]() Enter account details like server name (will be the server hostname on the network), username and password. Confirm that all data on the current disk will be overwritten by new data. ![]() An overview of the file systems is given before they are written to disk. By default we choose for ‘Use An Entire Disk’ when provisioning a new server. You could enter an Ubuntu mirror server close to your physical location (for faster download speeds), or you can opt for the default mirror. Depending on your network configuration, you can enter a proxy server for internet connectivity. If that’s not the case, than either there’s no DHCP server available on the current network segment, or you are facing Subiquity bug #1824483. Under normal conditions an IP-address will be assigned to the server via DHCP. After a while you’ll notice that the seeding process starts. Make sure your installation medium is listed before the harddisk. If this image doesn’t appear or you see a different operating system booting (the one currently on the harddisk) then go into the BIOS of the server and alter the boot sequence. Installing Ubuntu Server Once the server boots into the Ubuntu Server installation medium, you’ll see this image appear. Check if your server supports this feature, f.e. Use the onboard capabilities of the server to send the.You can use Rufus on Windows or Unetbootin on Windows, macOS or Linux.Īlternatively you can use the ‘ dd‘ command on both Linux and macOS to write the image file to the USB thumb drive. Note: burn the disc as an ‘Image’ and don’t just drop the file on the CD/DVD or else it won’t boot the server once the burn process is finished. Depending on the server model and its technical capabilities, you can use one of these options: iso image file needs to be transported to the intended server. The command stated there can be run in the Terminal on Linux (or you can use sha256sum), while on Windows you need a separate command ( CertUtil) or use the CRC check functionality built in a tool like 7-zip. This is needed to make sure that no corruption has occured during the download process. At the thank you page you can find the SHA256 hash to validate the downloaded. Preparationįirst off all, the Ubuntu Server image file needs to be downloaded. ![]() We chose for the long-term support version as this version will receive security patches until 2023, lowering our time investment in the maintenance of the server OS. The largest part of our cluster is running Ubuntu Server 18.04 LTS. For an enterprise like ours, licensing isn’t an issue, but for smaller companies or enthousiasts, licensing fees might be a hurdle to Windows Server as well. The reason not to choose for Windows Server is mainly based around the need for scheduled maintenance (updates, reboots, downtime etc.) while on Linux these updates often don’t require a server reboot. In our case, we’ve opted for the Linux OS. This is a document that can evolve over time, depending on changes and new insights we gather from our work on our computing cluster. In our case, we’re running BOINC and World Community Grid on dozens of servers and we face issues like a demand for low maintenance, high output and scalability. Most online manuals focus on the installation of the BOINC client on a consumer computer (Windows or macOS) or mobile device (Android). ![]()
