How To Install XMR-STAK on Ubuntu 16.04

How To Install XMR-STAK on Ubuntu 16.04 Console

Tutorial on the simplest Cryptonote miner on the market and how to install it on modern Ubuntu servers. Instructions should work for most Ubuntu releases, please let me know if you have problems and I will try to help.

XMR-Stak is a free and open-source Cryptonote miner that supports Monero (XMR) mining and other cryptonote coins.

This tutorial is based on the official github compile instructions located at https://github.com/fireice-uk/xmr-stak/blob/master/doc/compile_Linux.md

NOTE: use sudo before each command if you are getting permissions errors. If prompted for password, use your current username's password. If you are told this incedent will be reported or something to that effect, it just means your current user is not in the sudo subgroup, which means you need to have root give your user permission.

The basic install command line instructions are:

apt-get update
apt install libmicrohttpd-dev libssl-dev cmake build-essential libhwloc-dev
git clone https://github.com/fireice-uk/xmr-stak.git
mkdir xmr-stak/build
cd xmr-stak/build
cmake .. -DCUDA_ENABLE=OFF -DOpenCL_ENABLE=OFF
make install

You can now run the miner:

cd bin
./xmr-stak

However, there is a donation fee hardcoded into the app, so you may want to edit that if you are poor and just trying to get it running before you start giving away your earnings. Therefore, use the following instructions instead:

apt-get update
apt install libmicrohttpd-dev libssl-dev cmake build-essential libhwloc-dev
git clone https://github.com/fireice-uk/xmr-stak.git
mkdir xmr-stak/build

Now, change the donation to zero:

nano xmr-stak/xmrstak/donate-level.hpp

Find the line that says

constexpr double fDevDonationLevel = 2.0 / 100.0

and change it to

constexpr double fDevDonationLevel = 0.0 / 100.0

then use Ctrl-X to exit nano and do the following:

cd xmr-stak/build
cmake .. -DCUDA_ENABLE=OFF -DOpenCL_ENABLE=OFF
make install

Now, stay in the xmr-stak/build directory.

These last instructions are to optimize your mining.

First run the miner setup script:
cd bin
./xmr-stak

Follow the setup wizard -- most important is you need your wallet address and the pool address you are working with. Everything else is optional.

Once the miner is running, you should be getting status updates:

about blocks being found, difficulty changing, and results

1. Enable hugepages and run miner

   nano start.sh

add the following lines:

sysctl -w vm.nr_hugepages=128
/usr/local/src/xmr-stak/build/bin/xmr-stak

Ctrl-x to save and exit

Now run the miner again.
