![]() Install byobu and configure it to start on login. You can view ethminer output by running the command journalctl -u rvice -f Monitoring Once this is done, run sudo systemctl daemon-reload to force systemd to re-read its unit files, and then run sudo service eth-miner start to start ethminer. Make sure you include your correct wallet name in your connection URL, unless you want to give someone free ETH! I found that OpenCL would cause one CPU core to be pegged at 100%.īe sure to replace 127.0.0.1:8080/NAMEOFTHISRIG with the URL of whatever pool you are using. Create a file /etc/systemd/system/rvice and add the content from here, changing the variables as appropriate.Ĭhange the flag -G to -U if you want to use CUDA instead of OpenCL. Instead of running directly via the CLI, we should let systemd handle starting ethminer for us. Ensure the GPU driver is installed and loaded correctly. A value lower than this on a more powerful GPU would indicate an issue with your setup. On a single nVidia GTX 970 I observed roughly 20.78 MH/s on the above benchmark. ethminer -help, and perform a benchmark or two to ensure everything is working properly: ethminer -U -M. Visit the releases page on GitHub and download the latest version ( ethminer-X.YY.).Īs of the time of writing (July 2017), the project has a proper build pipline setup for both Windows and Linux 圆4, so there should be no need to compile it yourself.Įxtract the tar.gz archive to wherever you like (preferably somewhere in your $PATH) on your mining machine. We will be using ethminer but the below is also applicable for claymore. If the driver is not installed properly this command will output an error. The file /etc/modprobe.d/nf should exist with the following content:Īlso verify that the command nvidia-smi outputs a text-based table showing information about your GPU.lsmod | grep nouveau should return no output,. ![]() It is also no harm to check the open-source nouveau module is not loaded: When the system comes back up, verify the driver is loaded and running: lsmod | grep nvidia. NVIDIA-Linux-x86_64-XXX.XX.run to install the driver, just follow the prompts and then reboot when asked to do so. You will then be prompted to download a file named something like NVIDIA-Linux-x86_64-XXX.XX.run copy the link and download this using e.g. You need to select "Show More Operating Systems" to select Linux 64-bit, then you can select your particular graphics card. Once Ubuntu was installed I grabbed the official nVidia driver from their website. This is not required here, unless you want to overclock your GPUs using nvidia-settings (see #Overclocking). I did need to initially hook up a monitor to perform the installation, but once SSH was up and running this was no longer necessary.Īlso note that I did not install X11 or any form of GUI. I installed the base packages, build essentials and OpenSSH Server packages as this will be a headless build. Installing Ubuntu is outside of the scope of what I'm willing to write here, you can check the official documentation. Most folks seem to use Windows for mining, but I'd rather not have to deal with the random Windows Update-induced restarts and other miscellaneous annoyances that come bundled with it. I'm running Ubuntu Server 16.04 (LTS) on this machine. In OpenCL mode, one virtual core is pegged at 100%. The Intel processor is way overkill and is basically idle when mining in CUDA mode. The GTX 970 is a decent card - not the best for mining, but it's what I have.
