Appion-CentOS Install Manual:

by Neil Voss

1 Introduction¶

These are the Steps to install Appion on a CentOS machine

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.

2.1 Download the ISO disk of CentOS 5.3 ¶

1. ISO files are available at
   1. http://wiki.centos.org/Download
2. Click on i386 for 32bit machines or x86_64 for 64bit machines
3. Pick a mirror and download 'CentOS-5.3-x86_64-bin-DVD.iso' file

2.2 Burn ISO file to DVD disk¶

Use dvdrecord in Linux to burn disk

$ dvdrecord -v -dao gracetime=10 dev=/dev/dvd speed=16 CentOS-5.3-i386-bin-DVD.iso

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]

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:

$ username ALL=(ALL)       ALL

Logout and log back in with your username.
