So this is Amazon Linux, which is based on CentOS.
I ran: (systemctl is not on this, so must be based on CentOS)
[ec2-user@ip-172-31-23-217 ~]$ sudo initctl reload-configuration
[ec2-user@ip-172-31-23-217 ~]$ sudo service raintank-probe start
raintank-probe: unrecognized service
What should I do next to get this running? Can you point me to the binary folders?
