If using an Nvidia GPU, install the Nvidia CUDA toolkit:

Download installer type “deb(network)” from:

https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1604

To install issue the following commands:

$ sudo dpkg -i cuda-repo-ubuntu1604_9.1.85-1_amd64.deb
$ sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/7fa2af80.pub
$ sudo apt-get update
$ sudo apt-get install cuda

Editing the enviroment to include the CUDA path:

$ sudo nano /etc/environment

Find the PATH variable and include the /usr/local/cuda-9.1/bin folder at the end of the string.

Save the file and reboot.

If using and AMG GPU, install AMD APP SDK 3.0:

Download and install the latest version from:

http://developer.amd.com/amd-accelerated-parallel-processing-app-sdk/

Untar the SDK to a location of your choice.

Decompress the file wit the following command:

$ tar -xvjf AMD-APP-SDKInstaller-v<3.0.x.y>-GA-linux64.tar.bz2

Run the installer:

$ sudo ./AMD-APP-SDKInstaller-v<3.0.x.y>-GA-linux64.sh

To fix libOpenCL issue:

$ cd $AMDAPPSDKROOT/lib/x86_64
$ sudo ln -sf sdk/libOpenCL.so.1 libOpenCL.so

then logout and login again.

Installing amdgpu-pro

Download the latest package from:

https://support.amd.com/en-us/kb-articles/Pages/AMDGPU-PRO-Driver-for-Linux-Release-Notes.aspx

Decompress the file wit the following command:

$ tar -xJvf amdgpu-pro-17.40-492261.tar.xz
$ cd amdgpu-pro-17.40-492261
$ sudo ./amd-pro-install -y

Building xmr-stak from source

Install all dependencies:

$ sudo apt install git libmicrohttpd-dev libssl-dev cmake build-essential libhwloc-dev

Create a directory for the source files and clone the source:

$ mkdir GIT-sources
$ cd GIT-sources
$ git clone https://github.com/fireice-uk/xmr-stak.git

Create a build directory:

$ mkdir xmr-stak/build
$ cd xmr-stak/build

Configuring and building xmr-stak

If building xmr-stak for CPU only mining and without http server support, use the following cmake flags:

$ cmake .. -DCUDA_ENABLE=FALSE -DOpenCL_ENABLE=FALSE -DMICROHTTPD_ENABLE=FALSE

If building xmr-stak for AMD GPU mining and CPU mining, use the following cmake flags:

$ cmake .. -DCUDA_ENABLE=FALSE

If building xmr-stak for Nvidia GPU and CPU mining, use the following cmake flags:

$ cmake .. -DOpenCL_ENABLE=FALSE

If building for all (AMD GPU, Nvidia GPU and CPU mining)

$ cmake ..

After cmake finishes, execute the following to build:

$ make -j4 install

Final system configurations

If using GPU mining (Nvidia GPU or AMD GPU), ensure the user you will use to mine is part of the video group in /etc/group

$ sudo usermod -a -G video $LOGNAME

Enabling Large Page Support for AMDGPU-PRO

Edit /etc/default/grub and add GRUB_CMDLINE_LINUX=”amdgpu.vm_fragment_size=9″

After editing ggrub, do:
$ sudo update-grub
$ sudo reboot

Configuring Large Page Support for Operating system (applies to all GPUs and CPUs)

Create a file named 98-HugePages-miner.conf in /etc/sysctl.d with the following content:

############################
vm.nr_hugepages=128
############################

Add the following lines to /etc/security/limits.conf (where “miner” is the name of your mining account):

############################
miner soft memlock 262144
miner hard memlock 262144
############################

Then reboot with:

$ reboot

You will find the xmr-stak binary in ~/GIT-sources/xmr-stak/build/bin. Run xmr-stak and follow the prompts to begin mining.
