System Requirements
openDCIM is designed to run on a fairly cookie cutter LAMP system. However, there is no operating system specific code, so it could conceivably run on any operating system that can run the components.
- Apache Web Server 2.x, or similar web server, with page authentication set up for where you want to install openDCIM. We suggest installing openDCIM at the root of a configured server, such as dcim.domain.com, rather than www.domain.com/dcim/.
- MySQL 5.x - you can either run this on the same host or a separate host. Space requirements are very low.
- PHP 5.x - Make sure that you have libraries enabled for MySQL and SNMP access.
