Ubuntu Server Initial Setup
Here is the song & dance I do every time I start a new Ubuntu server. Nice cheat sheet for me to refer back to.
Create non-root user & enable SSH
If “ubuntu” user doesn’t exist, create it:
adduser ubuntu
usermod -aG sudo ubuntu
rsync --archive --chown=ubuntu:ubuntu ~/.ssh /home/ubuntu
Enable SSH: Set a password for the user and edit the SSH config file
passwd ubuntu
nano /etc/ssh/sshd_config
Remove the line “Import” blah blah blah
Uncomment AllowPasswordAuthentication yes
Install Tailscale
curl -fsSL https://tailscale.com/install.sh | sh
Quiet the login message
touch .hushlogin
For Meteor Apps
curl -sL https://deb.nodesource.com/setup_20.x -o nodesource_setup.sh
sudo bash nodesource_setup.sh
sudo apt-get install -y nodejs jq build-essential
sudo npm install -g pm2
pm2 startup
Install docker
# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
# Add the repository to Apt sources:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce
sudo usermod -aG docker $USER
Log out and back in!
