Recommended wiki for glossary for storyline

Hi guys,

I am new to Storyline and our producer will do the designing of the pages, so it is less about storyline itself. But the producer asked me to find out an appropriate wiki for the glossary we want to bind in. should be easy, but able to handle a lot of terms (i think it should be database-based). We can set it up on LAMP (Linux-Apache-MySQL-PHP) at our provider and the terms explanations will be bind into articulate via "lightbox". 

We have already about 1300 terms with explanations that add to a sum of 65.000 words and we are still at the beginning of the work ...

Any recommendations for an easy to handle wiki, which also can be filled with a .docx or .xlsx file? 

Thanks a lot for your help,

Tom
