Setting up a general web dev Ubuntu VPS

Vultr Ubuntu startup script.sh

# Startup script for Ubuntu 17.04 VPS on Vultr (Dev machine and cloud server)

# add a new user @todo: make this a one-liner
# adduser stvhwrd
# usermod -aG sudo stvhwrd

## MANUALLY LOG OUT AS ROOT AND LOG IN AS NEW USER

# OPTIONAL: to add ssh key, assuming that you have ssh-copy-id installed on local machine and your keypair is in ~/.ssh and named id_rsa:
# Locally, i.e. on your laptop.  eg. ssh-copy-id stvhwrd@45.63.10.205
ssh-copy-id stvhwrd@<IP_ADDRESS_OF_SERVER>

# log in with ssh key
# eg. ssh stvhwrd@45.63.10.205
ssh stvhwrd@<IP_ADDRESS_OF_SERVER>
