Appion

h1. Start with existing CentOS 5.3 64-bit installation

{{>toc}}

h2. 3 Download additional software 

h3. 3.1 Install the additional package repositories 

*NOTE*

There are several additional CentOS repositories that you can install.

These repositories provide additional packages, such as patented software (MP3 players),

closed source applications (Flash plugin, Adobe Acrobat Reader)

and lesser used packages (python numpy, Gnu Scientific Library).

But some repositories install packages over other packages,

which can cause problems and conflicts (ATrpms is bad at this). So I recommend only installing

EPEL and RPM Fusion. Read more here:

"CentOS Additional Repositories":http://wiki.centos.org/AdditionalResources/Repositories 

h4. 3.1.1 Extra Packages for Enterprise Linux (EPEL) 

* http://fedoraproject.org/wiki/EPEL

* contains a wealth of packages required for appion

.Download repository rpm and install

<pre>

$ sudo rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/`uname -i`/epel-release-5-3.noarch.rpm

</pre>

h4. 3.1.2 RPM Fusion 

* http://rpmfusion.org/

* good for mp3 and other patent limited software

.Download repository rpms and install

<pre>

$ sudo rpm -Uhv http://download1.rpmfusion.org/free/el/updates/testing/5/`uname -i`/rpmfusion-free-release-5-0.1.noarch.rpm

$ sudo rpm -Uvh http://download1.rpmfusion.org/nonfree/el/updates/testing/5/`uname -i`/rpmfusion-nonfree-release-5-0.1.noarch.rpm

</pre>

h3. 3.2 Update current packages 

.Update the updater to make life easier

<pre>

$ sudo yum -y update yum

</pre>

.Update all packages

<pre>

$ sudo yum -y update

</pre>

*NOTE*

Download was over 129 MB (in July 2009). If you have a slow internet connection you can setup presto/deltarpms, "see this email]":http://www.linux-archive.org/centos-development/222706-presto-deltarpm.html 

You may want to restart your computer when this completes.

h4. .Install Complete list of additional packages:

* *python tools*: python-tools python-devel

* *general applications*: subversion ImageMagick grace gnuplot python-matplotlib

* *Tilt Picker*: wxPython numpy scipy python-imaging

* *FindEM*: gcc-gfortran compat-gcc-34-g77

<pre>

$ sudo yum -y install \

python-tools python-devel python-matplotlib \

subversion ImageMagick grace gnuplot \

wxPython numpy scipy python-imaging \

gcc-gfortran compat-gcc-34-g77 \

</pre>

If you have an nVidia video card and setup RPM fusion, install the nVidia binary, will speed things up especially for UCSF Chimera

<pre>

$ sudo yum -y install nvidia-x11-drv

</pre>

.Clean up packages to save drive space

<pre>

$ sudo yum clean all

</pre>

.Re-index the hard drive, this will come in handy later

<pre>

$ sudo updatedb

</pre>

.Enable servers on reboot

</pre>

<pre>

$ sudo /sbin/chkconfig mysqld on

you should see the line:

<pre>

* Checking for MPI ... yes

</pre>

<pre>

h2. 9 Install a PBS job submission system

You'll need to install a "Portable Batch System":http://en.wikipedia.org/wiki/Portable_Batch_System for job submission, such as "TORQUE":http://en.wikipedia.org/wiki/TORQUE_Resource_Manager . I know Torque comes with Fedora 10, but not CentOS.

* An RPM is available in the EPEL testing section

<pre>

$ sudo yum -y --enablerepo=epel-testing install torque

</pre>

or another way to get packages

<pre>

$ wget http://centos.karan.org/el5/extras/testing/`uname -i`/RPMS/torque-2.1.9-1.el5.kb.`uname -i`.rpm

$ sudo yum -y localinstall --nogpgcheck torque-2.1.9-1.el5.kb.`uname -i`.rpm

$ #sudo rpm -Uhv torque-2.1.9-1.el5.kb.`uname -i`.rpm

</pre>

After installing torque it needs to be configured. Sorry, we have no documentation for configuring torque at this time. You may try http://www.clusterresources.com/products/torque-resource-manager.php
