Building a rock solid multi-gpu linux mining rig with CEntOS 6.0

[Viceroy]

After a fresh install this seems to be working to block yum from upgrading outside the distro I'm using (centos 6.0 for test)

Code:

####  become root user
su -

#### change directory to yum repo directory
cd /etc/yum.repos.d

#### move original file to backup
mv -f CentOS-Base.repo CentOS-Base.repo.old

# COPY the following into your buffer 
## (in windows you use ctrl-c)
##
## start copy ---->>

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the #mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

5.9 didn't work for me either. For the record I've now installed Doze 7 and am mining like a champ.  I hate windows especially for a machine that I plan on running 24/7, but oh well.  I'm installing cygwin now to make it at least easier to manage remotely.

5.9 didn't work for me either. For the record I've now installed Doze 7 and am mining like a champ.  I hate windows especially for a machine that I plan on running 24/7, but oh well.  I'm installing cygwin now to make it at least easier to manage remotely.  

I just completed my install with centos 6.0 and after locking up yum it works exactly as expected....

Code:

Give it a try if you like, here's the update directions... gonna clean it up and repost, but here it is for now...

####  While at your windows desktop machine you need to 
####  download the ISO from http://vault.centos.org/6.0/isos/
####
####  (I will be using the 64 bit OS from here on out)
####
####  The ISO can be burned to CD, DVD or USB
####
####  (I will burn the ISO to a 2GB+ USB flash drive)
####
####  Download the ISO from:
####  http://vault.centos.org/6.0/isos/x86_64/CentOS-6.0-x86_64-LiveCD.iso
####
####  Download and install Pendrivelinux Windows Software:
####  http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/
####
####  0. Plug in your flash drive and wait for it to register
####
####  1. start pendrivelinux universal USB installer
####  2. selects CentOS from "other distros alphabetically"
####  3. select the CentOS LIVE iso you downloaded
####     (CentOS-6.0-x86_64-LiveCD.iso)
####  4. select your drive letter and format the drive
####  5. safely remove flash drive and plug into new machine
####  6. boot up and install CentOS with the menus
####  7. after intallation log in as root (or su) and:
####	7a. set up network so IP is fixed so you can log in remotely
####	7b. turn on the SSH daemon so you can log in (service sshd start)
####	7c. make sshd starts each time you boot (chkconfig sshd on)
####  8. now I like to go back to my nice desk and chair
####    8a. dowload and install putty so you can talk to your box
####    http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
####    using a new ssh connection, connect to your machine as the
####    user you set up during installation.  (it's a bad idea to log
####    in as root from a remote location).
####   9. while you are sitting there at your desk download and install
####    xming windows xwindow emulator from here:
####    http://sourceforge.net/project/downloading.php?group_id=156984&filename=Xming-6-9-0-31-setup.exe
####  10. modify yum
####
####  cut and paste one command at a time

You happen to have a good link to vanilla Centos6.0x64?  All the ones I've tried say its deprecated and point to a newer version.  The link in your howto doesn't work...

edit: n/m finally found one.  http://mirrors.usc.edu/pub/linux/distributions/centos/6.0/isos/x86_64/

[Viceroy]

You happen to have a good link to vanilla Centos6.0x64?  All the ones I've tried say its deprecated and point to a newer version.  The link in your howto doesn't work...

The vault appears to be down right now.  It is the place to get this.

Here's the google mirror of the centos vault

http://webcache.googleusercontent.com/search?q=cache:http://vault.centos.org/6.0/isos/x86_64/

Unfortunately the individual links appear down.  I'm certain it will be back shortly.

edit:
it came back

[papaminer]

have you tried running centos 6 on thumb drive is it possible?

[Viceroy]

Yea, when you put the "LIVE" CD or DVD on a thumb drive you can launch and run from that.  There is no reason to install the OS to the hard drive if you do not want to.  The flash drive is slower than the hard drive though.

[papaminer]

kool..

thanks a lot for the howto...

will try doing it later... i have 2 pc doing nothing... and has hd 6870 x2 and hd 6950 x2... i just hope the mobo have pcie x1 so i can just buy risers to x16 and get more gpu's..

have you tried using 3 or quad hd 7970 on this setup?

[papaminer]

Yeah.. i know it is slow.. i just tried it last night with ubuntu from kano's tutorial on cgminer... I did see some advice on getting a faster thumb drive.. like the patriot supersonic boost XT usb 3.0... i am currently heading to the store to get 2... and will try it with centos 6..

[Viceroy]

have you tried using 3 or quad hd 7970 on this setup?

I have six AX6870x2's they are dual gpu cards.  When I try to run three of them I have heat problems.  I can only run two per motherboard.

[papaminer]

lol.. this is harder than I thought..

i am stuck at section 2 - 7a

plus.. all the changes I make on the OS.. does not get saved when rebooted... (which is good coz I know i messed up... lol)

[Viceroy]

The guide is designed to install centos and the drivers on a fresh machine.  If you intend to follow the guide you will be over-writing your hard drive.  You asked if you could use centos on a USB, yes.  But I have no idea how to build an executable centos miner on a usb.  This guide does not do that.

[papaminer]

Hi,


the reason why I got stucked in section 2 7a. was because of auto eth0... and I cannot seemed to find it or over ride it... but I was able to just use it as it is... and not create eth0 anymore..

anyway...
I was able to get up to Section 4...

we're supposed to uncompress 2.4 right? and this tutorial:

is this supposed to be a root user or miner?

I cannot seem to follow the glowing text above...
and when I do:

tar -xf /home/miner/miningpacks/AMD-APP-SDK-v2.4-lnx64.tgz


im getting these:

Code:

tar: AMD-APP-SDK-v2.4-lnx64/Makefile: Cannot open: File exists
tar: AMD-APP-SDK-v2.4-lnx64: Cannot utime: Read-only file system
tar: AMD-APP-SDK-v2.4-lnx64: Cannot change ownership to uid 0, gid 0: Read-only file system
tar: AMD-APP-SDK-v2.4-lnx64: Cannot change mode to rwxr-xr-x: Read-only file system
tar: Exiting with failure status due to previous errors

all tar stuff is as root.  if you did the previous section all the stuff should be in /home/miner so that looks ok.  looks like you are trying to over write existing files.  go back to the top where it shows the directories to remove for a clean install

I'd like to see you remove the /opt/ amd directories and try that part again.  or perhaps you are trying to tar as a user other than root ... that could be the problem.   the  idea is to store the packages in the user directory and actually run the program as a user.  but some of The stuff like installing drivers or compiling the mining program require you to be root.

uhmmm stuck again.. lol

[root@livecd miningpacks]# export DISPLAY=:0
[root@livecd miningpacks]# glxgears
No protocol specified
Error: couldn't open display :0
[root@livecd miningpacks]#

ok, you look awfully close to success....

What I do, and I cannot explain why this works, is I go to the machine directly (the head) and I log in as a regular user.  Then I open a "terminal window" by pulling down from the menu on the top left.    This must cause the X system to turn on as that user because doing that step then allows me to log in remotely and set my display (export DISPLAY=:0).  Once that is done I can use all the X tools. 

If I use xming on my PC the gears pop up on my local (remotely connected) machine.  IF I am at the head, or am not using an x-windows emulator on my pc the gears program pops up on the "head" of the linux box.

If you can see the gears, you can probably mine.

I already did this.. but no success...

also my current setup is with 2 pc.. 1 monitor/1keyboard/1mouse... and using KVM to switch to different pc/monitor...

but I can already see all 2 gpus...

Code:

[root@livecd ~]# aticonfig --lsa
No protocol specified
* 0. 01:00.0 AMD Radeon HD 6900 Series
  1. 02:00.0 AMD Radeon HD 6900 Series

so it is good that you see the gpus you are very close.  you need to be able to use fglrx as well.  you are using the drivers from the guide, not the latest drivers right?

[papaminer]

Yes.. I used the old school drivers like the tutorial said...

i think i messed up with basic libraries.. i also can't install cgminer properly.

Code:

checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for LIBCURL... no
checking for LIBCURL... no
configure: error: Missing required libcurl dev >= 7.18.2
[miner@livecd cgminer]$

If I re-do everything.. it will be my 5th time.. lol..

btw...

if I do this properly on this thumb drive...

can I just copy the entire thumb drive and paste it into another thumb drive and it is going to be a clone?

or I have to re-do everything on each thumb drive?
