Installation Requirements

Evergreen Installation Requirements:

The Official Evergreen Documentation lists the following requirements for Evergreen 2.2:

Server Minimum Requirements

The following are the base requirements setting Evergreen up on a test server:

  • An available desktop, server or virtual image
  • 1GB RAM, or more if your server also runs a graphical desktop
  • Linux Operating System
  • Ports 80 and 443 should be opened in your firewall for TCP connections to allow OPAC and staff client connections to the Evergreen server.

Staff Client Requirements

Staff terminals connect to the central database using the Evergreen staff client, available for download from The Evergreen download page. The staff client must be installed on each staff workstation and requires at minimum:

  • Windows (XP, Vista, or 7), Mac OS X, or Linux operating system
  • a reliable high speed Internet connection
  • 512Mb of RAM
  • The staff client uses the TCP protocal on ports 80 and 443 to communicate with the Evergreen server.

Barcode Scanners

Evergreen will work with virtually any barcode scanner – if it worked with your legacy system it should work on Evergreen.


Evergreen can use any printer configured for your terminal to print receipts, check-out slips, holds lists, etc. The single exception is spine label printing, which is still under development. Evergreen currently formats spine labels for output to a label roll printer. If you do not have a roll printer manual formatting may be required.
