Simple help regarding elasticsearch

Simple questions, need to fix my elasticsearch (if it's even installed properly)
Unable to get it up and running at the same time as Redis (Opening one leads the other to close)

Various errors pop up when elasticsearch is open, so it seems it's unable to retrieve data
"{"error":{"root_cause":[{"type":"index_not_found_exception","reason":"no such index","resource.type":"index_or_alias","resource.id"

I'm sure this is basic stuff so, message me if you have the required knowledge!
