This is a simple how to on how to get Folding at Home (distributed computing) software to run on your Linux box.  I have three of these instances running on my dedicated servers and they are folding away!  Be sure to add [laatedaa?]’s folding at home team number 88046.  All you need is SSH with root access and just a few commands that I have listed here.

Here are a few very easy steps to setup lxadmin.  You can do it easily with a few commands in SSH.

All you really need is a server with SSH access and root access to that SSH.

Make sure that you open the ports 7778 and 7777 in the firewall. Otherwise you won’t be able to connect to lxadmin.

Lxadmin installation consists of downloading either the lxadmin-install-master.sh or lxadmin-install-slave.sh from download.lxlabs.com and executing them as root. They will download all the required files and do the complete installation on their own.

The master copy is mainly for single server configurations.  The slave copy, on the other hand, is for multiple server configurations.  If you would like to have multiple servers, install the master copy on one of the servers and then install the slave copy on all the other servers and list the servers on the master copy.  If you want to do only one server, just simply install the master server.

Lately I’ve been receiving a lot of queries and request to install this setup on quite a few boxes so I decided to write a guide (CentOS Based). It also includes copy & paste commands so it should be relatively easy to follow. Note: It shouldn’t be impossibly hard to modify this to work with other distros (Here’s one for a generic distro).

The following Guide will show you exactly how to install the following packages on a CentOS system:

• FFmpeg
• FFmpeg-PHP
• Mplayer + Mencoder
• flv2tool
• LAME MP3 Encoder
• AMR (for 3gp file conversions)
• Libogg
• Libvorbis

Setup the directory to use

(Wouldn’t want /root to start getting crowded, would we?)
mkdir /usr/local/src
cd /usr/local/src

Dowload the necessary files.

wget http://www3.mplayerhq.hu/MPlayer/releases/codecs/essential-20061022.tar.bz2
wget http://rubyforge.org/frs/download.php/9225/flvtool2_1.0.5_rc6.tgz
wget http://easynews.dl.sourceforge.net/sourceforge/lame/lame-3.97.tar.gz
wget http://superb-west.dl.sourceforge.net/sourceforge/ffmpeg-php/ffmpeg-php-0.5.1.tbz2
wget http://downloads.xiph.org/releases/ogg/libogg-1.1.3.tar.gz
wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.1.2.tar.gz
wget http://ftp.penguin.cz/pub/users/utx/amr/amrnb-6.1.0.4.tar.bz2
wget http://ftp.penguin.cz/pub/users/utx/amr/amrwb-6.0.0.1.tar.bz2

Extract all the files

tar zxvf flvtool2_1.0.5_rc6.tgz
tar zxvf lame-3.97.tar.gz
tar zxvf libogg-1.1.3.tar.gz
tar zxvf libvorbis-1.1.2.tar.gz
tar zxvf flvtool2_1.0.5_rc6.tgz
tar jxvf essential-20061022.tar.bz2
tar jxvf ffmpeg-php-0.5.1.tbz2
tar jxvf amrwb-6.0.0.1.tar.bz2
tar jxvf amrnb-6.1.0.4.tar.bz2

Create a folder to hold the codecs

mkdir /usr/local/lib/codecs/

Make sure we have all the necessary libraries as well as SVN + Ruby installed

yum -y install gcc gmake make libcpp libgcc libstdc++ gcc4 gcc4-c++ gcc4-gfortran subversion ruby ncurses-devel

Get ffmpeg and mplayer via SVN

svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer
cd /usr/local/src/mplayer
svn update
cd /usr/local/src

Copy Codes for Mplayer

mv /usr/local/src/essential-20061022/* /usr/local/lib/codecs/
chmod -R 755 /usr/local/lib/codecs/

Create a temp dir with 777 permissions (needed to install ffmpeg)

mkdir /usr/local/src/tmp
chmod 777 /usr/local/src/tmp
export TMPDIR=/usr/local/src/tmp

Direct your browser to view a phpinfo() php file. Scroll down and you should see the ffmpeg extension.

Wasn’t all that hard was it?
