Hi ComfortableHorse5 ,
No, unless you need to override any settings, these default settings are already part of the built-in server.

I’ve launch the ami a few times however, it seems to blank.

Can you provide more info? What do you see when you surf to http://<server-public-address>:8080 ? Note it might take a few mins for the server to finish booting up (especially due to the load time of ElasticSearch)
