2. Install Ubuntu Server on Dedicated Server

3. Install and configure MongoDB on the Server. This will be used as the database for your application.

# Add Key
wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list

# Install MongoDB
sudo apt-get update
sudo apt-get install -y mongodb-org

# start mongodb
sudo systemctl start mongod

# set mongodb to start automatically on system startup
sudo systemctl enable mongod

# install pm2 with npm
sudo npm install -g pm2
