h1. Web Server Installation on CentOS 6 

 This is a work in progress. We'll write documentation on Appion Web Server Installation on CentOS 6 as we go. 

 Before you start, make sure you have CentOS 6 installed on your computer. Note that upgrade CentOS 5 to CentOS 6 can damage existing filesystems and operating systems as described in "CentOS Migration Guide":http://wiki.centos.org/HowTos/MigrationGuide. That's why we recommend starting with a fresh install of CentOS 6. The following links provide excellent step by step guide on how to install CentOS 6 Linux from scratch on a new machine:

 h3. [[Install Web Server Prerequisites]] 

 First install Extra Packages for Enterprise Linux (EPEL) - http://fedoraproject.org/wiki/EPEL 

 <pre> 
 wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-7.noarch.rpm 
 rpm -ivh epel-release-6-7.noarch.rpm  
 </pre> 

 Note that release version (6-7) is the current release at the time of this writing. Please click "here":http://mirrors.cat.pdx.edu/epel/6/i386/repoview/epel-release.html to get the newest 'epel-release' package. 

 Now install all prerequisites 

 <pre> 
 yum install php-gd gcc phpMyAdmin libssh2-devel php-pecl-ssh2 mod_ssl httpd php-mysql php-devel php fftw3-devel svn python-imaging python-devel mod_python scipy 
 easy_install fs PyFFTW3 
 </pre> 

 h3. [[Configure php.ini]] 

 Edit /etc/php.ini and change line ~229 to 
 <pre> 
 short_open_tag = On 
 </pre> 

 Note that short_open_tag appears twice in /etc/php.ini and you need to set "short_open_tag = On":http://www.apachefriends.org/f/viewtopic.php?p=155513 at around line 229 for it to take effect.
