it's tricky to find the Domino download you need

HCL Notes/Domino 8.5 Forum (includes Notes Traveler)

Subject:

Starting with Notes 4.6 the Domino server is a separate install. It's no longer bundled with Notes. The same goes for Domino Designer, it's been a separate application since 5.0.

1) Go here:
http://www.ibm.com/developerworks/downloads/ls/lsds/

2) Click the "Local install using Download Director or HTTP" link.

3) Log in using your IBM ID.

4) Select the first entry, "IBM Lotus Notes and Domino 8.5 Multiplatform English Trial eAssembly", scroll to the bottom of the page and click Continue.

5) Fill out the marketing page and click Continue.

6) In the list of downloads you want this one: "IBM Lotus Domino 8.5 Linux for xSeries English Trial C1SD4EN.tar". IBM's line of Intel servers is called "xSeries" and they assume everyone knows that.
