=== RUN AT YOUR OWN RISK ===

DO NOT RUN ON EXISTING INSTALLATIONS, YOU *WILL* LOSE DATA

This script:
 * Installs Zabbix 1.8.x on CentOS / Red Hat 5
 * Drops an existing database
 * Does not install MySQL; to install type "yum install mysql-server"
 * Assums a vanilla OS install, though it tries to work around it
 * Does not install zabbix packages, it uses source from zabbix.com

Press Ctrl-C now if you want to exit

Wait 5 seconds...
