How to implement ElastiFlow on CentOS 7

I'm new to using ElasticStack, and I'm trying to use ElastiFlow on CentOS7. I've looked into the ElastiFlow official website, but they don't specify support and install guideline on CentOS. Can someone advise or guide me through how to achieve this? I know it's a lot, but I really needed this and I'd appreciate if anyone can help out with this. Thank you.
