• How to create a droplet
• Basic server setup including creating a sudo user and setting up a ufw firewall

Create a new ssh keys

Create two, one for root on the server and one for the main user

*make sure to create them in the ./ssh folder

From the home directory on your local computer run:

$ ssh-keygen
./.ssh/vps_demo

Create a droplet

1. Go to https://www.digitalocean.com/

2. Create an an account or signin

3. Create a new droplet

   • Ubuntu 18 is fine
   • basic 5$ a month plan

4. Add the root ssh key

   Easily copy to the condense of a file to the clipboard with:

   $ pbcopy < ./.ssh/demo_root_key.pub
   

5. Navigate to the droplet dashboard and wait for it to be created

Basic Server Setup

Great tutorial from digital ocean

1. Using thee ip address from the droplet dashboard

   $ ssh -i ~/.ssh/demo_root_key root@666.66.66.66
   root@demo_vps:~ $
   

2. Setup up firewall

   root@demo_vps:~ $ ufw allow 22/tcp
   root@demo_vps:~ $ ufw enable
   root@demo_vps:~ $ ufw status
   

3. Create a new sudo user

   root@demo_vps:~ $ adduser travis
   root@demo_vps:~ $ usermod -aG sudo travis
   

4. Add user ssh key to sudo user

   Copy the key to the clipboard on the local machine:

   $ pbcopy < ./.ssh/demo_travis_key.pub
   

   Append the key to the end of the authorized_keys files on the remote machine:

   root@demo_vps:~ $ vim /home/travis/.ssh/authorized_keys
   

5. Exit root ssh session and test logging in to sudo user

   ssh -i ~/.ssh/demo_travis_key travis@666.66.66.66
   travis@demo_vps:~ $
   

6. If all went well you now have yourself a server! 🥳
