Adding a deploy user in Linux with some less headache goodies (not typing or using password)

deployUser_config.md

(wherever it says url.com, use your server's domain or IP)

Login to new server as root, then add a deploy user

sudo useradd --create-home -s /bin/bash deploy
sudo adduser deploy sudo
sudo passwd deploy

And Update the new password

Now login as that user

ssh [email protected]

Make directory .ssh on the remote server and log out

mkdir .ssh
exit

Push your ssh key to the authorized_keys file on the remote server

scp ~/.ssh/id_rsa.pub [email protected]:~/.ssh/authorized_keys

Copy SSH keys

ssh-copy-id deploy@<ubuntu-server-ip-address>

Disable password authentication

sudo vim /etc/ssh/sshd_config
# To disable tunneled clear text passwords, change to no here!
PasswordAuthentication no
#PermitEmptyPasswords no
PubkeyAuthentication yes

Disable password prompt for deploy user when using the sudo command

sudo visudo
# Deploy
deploy ALL=(ALL) NOPASSWD:ALL
