It sounds like you are requesting help with the provisioning of a server at Digital Ocean? If so I suggest you follow their process to bring your server online. You will at some point during the Digital Ocean setup need to decide what OS you want to install (Windows / Linux) and in addition you will need to record the IP or URL provided to allow you to find your server system on the Internet once functional. I suspect for a $1 a month you will have most likely chosen to commission a Linux server (Ubuntu). If so then follow the Manager setup instructions here:- Ubuntu
All the Manager install instructions can be carried out remotely using a ssh connection. Once you are logged in remotely to your new server at your allocated IP or URL the Manager install process should follow what is in the link above. Good Luck.
