h1. Instructions for Start from scratch by installing CentOS on your computer
*Appion-CentOS Install Manual:*
by Neil Voss
h2. 1 Introduction
These are the Steps to install Appion on a CentOS machine
h2. 2 Install CentOS operating system
*NOTE:* CentOS vs. RHEL
_CentOS is the exact same as Red Hat Enterprise Linux (RHEL), except that it is free and supported by the community_
The reason I mention CentOS is because I wanted to keep the guide really simple. Another student and I run appion on Fedora 10 and we've run appion on SuSe in the past. I know we gotten most bits working on MacOSX, but some of the python libraries contain ancient Fortran code that does not compile easily on a Mac. But CentOS is certainly not a requirement in general, it is just that the first iteration of the guide is written for CentOS.
h3. 2.1 Download the ISO disk of CentOS 5.3
# ISO files are available at
## http://wiki.centos.org/Download
# Click on i386 for 32bit machines or x86_64 for 64bit machines
# Pick a mirror and download 'CentOS-5.3-x86_64-bin-DVD.iso' file
h3. 2.2 Burn ISO file to DVD disk
Use dvdrecord in Linux to burn disk
<pre>
$ dvdrecord -v -dao gracetime=10 dev=/dev/dvd speed=16 CentOS-5.3-i386-bin-DVD.iso
</pre>
h3. 2.3 Install CentOS 5.3 with default packages
* Only "Desktop - GNOME" is assumed to be installed
* More information available at [http://wiki.centos.org/Documentation CentOS Documentation]
h3. 2.4 Add yourself to the sudoers file
Make sure you have root permission.
Open the file in an editor. ex. vi /etc/sudoers
Look for the line: root ALL=(ALL) ALL.
Add this line below the root version:
<pre>
$ username ALL=(ALL) ALL
</pre>
Logout and log back in with your username.
