Start xmr-stak as service in ubuntu

Note to self on how to get xmr-stak working on startup on ubuntu 17.10.

prerequisite: build xmr-stack-cpu

create service folder and copy files from bin folder to it
sudo mkdir /usr/local/xmr
sudo cp * /usr/local/xmr/.

cd /usr/local/xmr/

create start script in /usr/local/xmr

sudo nano server.sh

#!/bin/bash

PID=""

function get_pid {

   PID=`pidof xmr-stak-cpu`

}

function stop {

   get_pid

   if [ -z $PID ]; then

      echo "server is not running."

      exit 1

   else

      echo -n "Stopping server.."

      kill -9 $PID

      sleep 1

      echo ".. Done."

   fi

}

function start {

   get_pid

   if [ -z $PID ]; then

      echo  "Starting server.."

      sysctl -w vm.nr_hugepages=128

      ./xmr-stak-cpu &

      get_pid

      echo "Done. PID=$PID"

   else

      echo "server is already running, PID=$PID"

   fi

}

function restart {

   echo  "Restarting server.."

   get_pid

   if [ -z $PID ]; then

      start

   else

      stop

      sleep 5

      start

   fi

}

function status {

   get_pid

   if [ -z  $PID ]; then

      echo "Server is not running."

      exit 1

   else

      echo "Server is running, PID=$PID"

   fi

}

case "$1" in

   start)

      start

   stop)

      stop

   ;;

   restart)

      restart

   status)

      status

   *)

      echo "Usage: $0 {start|stop|restart|status}"
