==INTRODUCTION==
In this tutorial we will present '''how to mine Bitcoin or another cryptocurrency''' with GPU (or CPU) on a dedicated server under Ubuntu 16.04.

This {{Template:Serveur}} can be rigged with one or several '''NVidia GeForce GTX 1070''' cards to process the algorithms used in these blockchains.

In this case, we’re using a '''[https://www.ikoula.com/en/dedicated-server#hd XEON GPU]''' server from '''Ikoula'''’s lineup with one graphic card to mine '''AltCoins'''.

==PREREQUISITES==

It may be easier for some people to use a VNC client for the install :
https://doc.ubuntu-fr.org/vnc

'''Nvidia 387 Drivers''' or latest stable release : https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa

'''CUDA 9''' or latest stable release : https://developer.nvidia.com/cuda-downloads

'''CCMiner''' or any other miner : https://github.com/tpruvot/ccminer

==INSTALLATION==

Connect to your '''XEON GPU''' server through '''SSH''' with your favorite ssh client.

Update your system.
<syntaxhighlight lang="bash">
$ sudo apt-get update
$ sudo apt-get upgrade
</syntaxhighlight>

==== Download Nvidia Drivers ====

First we must add the repository for all ‘’’Nvidia’’’ drivers, then install the drivers we need :
<syntaxhighlight lang="bash">
$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt-get update
$ sudo apt-get install nvidia-387
</syntaxhighlight>
This install may take a few minutes, we recommend you make a cup of coffee for the next steps .
<div style="background-color: #FFCC99;"> '''Note''': If you see warnings for cryptsetup, just ignore them because cryptsetup is not installed. Just an informative message.</div>

Now we need to '''reboot the server''' for our GPU to be recognized, and reconnect :
<syntaxhighlight lang="bash">
$ sudo shutdown -r now
</syntaxhighlight>

Everything is ready for the next step. We can verify that our GPU is setup correctly, and check their state, with the ‘’’Nvidia-smi’’’ tool. Just type :
<syntaxhighlight lang="bash">
$ nvidia-smi
</syntaxhighlight>

==== Download CUDA Drivers====

Go to the following website : https://developer.nvidia.com/cuda-downloads
Select “'''Operating System” -> Linux - > x86_64 -> Ubuntu -> 16.04 -> deb(local)'''”
Copy the link to the file to download (Approx. 1,2Gb) or download directly if you’re using a VNC :
In our case (without VNC) :
<syntaxhighlight lang="bash">
$ wget https://developer.nvidia.com/compute/cuda/9.0/Prod/local_installers/cuda-repo-ubuntu1604-9-0-local_9.0.176-1_amd64-deb
</syntaxhighlight>
[[File:Nvidia LI.jpg|800px]]

The Installation Instructions for the Base Installer are described right underneath the download link in 4 steps.
Please change the cuda-repo.. file according to the version you’ve chosen !
In our case :
<syntaxhighlight lang="bash">
$ sudo dpkg -i cuda-repo-ubuntu1604-9-0-local-9.0.176-1_amd64.deb
$ sudo apt-key add /var/cuda-repo-9-0-local/7fa2af80.pub
</syntaxhighlight>
<div style="background-color: #FFCC99;"> '''Note''': If the first command “dpkg” gives you an error asking to install the key, do so, then dpkg again .</div>

Now we can install '''CUDA''' :
<syntaxhighlight lang="bash">
$ sudo apt-get update
$ sudo apt-get install cuda
</syntaxhighlight>

We’re done here, our graphic cards are setup correctly with the latest drivers . We can now install our miner software .

==== Download CCMiner====

First we need to prepare the libraries and dependencies, and update them, so we can install our cryptocurrency mining software :
<syntaxhighlight lang="bash">
$ sudo apt-get build-essential libcurl4-openssl-dev make automake git gcc-5 libjansson-dev libssl-dev autotools-dev
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 1
</syntaxhighlight>

Now to install '''CCMiner''' :
<syntaxhighlight lang="bash">
$ git clone https://github.com/tpruvot/ccminer
$ cd ccminer
$ ./autogen.sh
$ ./configure CFLAGS=”-O3 -Wall -march=native”
</syntaxhighlight>

Before we '''build''' we must make sure the miner is optimised for our ‘’’GeForce GTX 1070’’’ - and according to the readme and manual ( https://github.com/tpruvot/ccminer/wiki/nvcc_ARCH-=--gencode=arch=compute_20,code=%22sm_21,compute_20%22 ) we see our GPU is compatible with '''CUDA 8''' (at least) and that our ''' “nvcc flag”''' is '''“sm_61 / compute_61”''' which we will change in the '''Makefile.am''' file aux lignes '''114, 115, 116, 117, 118, 119, 179, 184, 187, 190, 193, 196'''.
For the first 4 lines you can just add a # to comment the line . Make the changes everywhere required.

Voilà, the miner is optimized . We can finally '''install''' :
<syntaxhighlight lang="bash">
$ ./build.sh
</syntaxhighlight>
<div style="background-color: #FF9999;"> '''Warning''': If the command "'''build.sh'''" outputs an error, you havent correctly changed the '''nvcc flag''' in the '''Makefile.am''' as described above .</div>

Now your cryptocurrency mining software is installed , you can create a '''script''' to launch the miner quickly :
<syntaxhighlight lang="bash">
$ touch launcher.sh && chmod +x launcher.sh
$ vi launcher.sh
</syntaxhighlight>

Your '''script''' might look a little like this :
<syntaxhighlight lang="bash">
#!/bin/bash
./ccminer -a algorithm -i 2 -o stratum+tcp://pool.mining.com:12016 -u user -p x
</syntaxhighlight>
<div style="background-color: #FFCC99;"> '''Note''': To better understand the arguments to launch ‘’’ccminer’’’, type this in your terminal :
<syntaxhighlight lang="bash">
$ ./ccminer --help
</syntaxhighlight></div>

Then, to launch your '''script''', type :
<syntaxhighlight lang="bash">
$ ./launcher.sh
</syntaxhighlight>

==CONCLUSION== 

There you go ! In less than 30 minutes , your [https://www.ikoula.com/fr/serveur-dedie XEON GPU] server hosted by '''Ikoula''' is '''mining bitcoin, ethereum, litecoin, or any other cryptocurrency''' for a blockchain.
