install haproxy - elastic search / redis for magento 2

Hello
we have a dedicated server and we need to do this points:
- install haproxy for firewall
- elastic search / redis for magento 2
- set only connection from cloudflare allowed, no directly to server.
set local mail delivery
- check if automated backup is done
- close all ports of servers
- need set https headers for server, that did set on cloudflare.

Thanks
