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:

    30
    
    
    
Edit /etc/php.ini and change line ~229 to

<pre>





    32
    
    
    
short_open_tag = On





    33
    
    
    
</pre>





    34
    
    
    





    35
    
    
    
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.

Also available for centos6 is the myami-2.2-redux branch. This has the same features as the 2.2 release, but the portions of myami that were incompatible with Centos5 have been replaced with what we call Redux.
