curl -fsSL https://gist.githubusercontent.com/AminulBD/9061f8a8c99e772249569aa1e6e5a362/raw/bootstrap.sh | bash -s

How to use this:

• Download this script as root: https://gist.githubusercontent.com/AminulBD/9061f8a8c99e772249569aa1e6e5a362/raw/bootstrap.sh
• Make it executable as: chmod +x bootstrap.sh
• Run the script: ./bootstrap.sh and follow the instructions.

Also, you can pass all info directly by: ./bootstrap.sh --domain=aminul.net --user=aminul

This script will generate mysql root password and will be stored in ~/.mysql_password file.

# This script will install LEMP (w/ composer & wp cli) and Node (w/ PM2 & Yarn).
# This setup is similar as laravel forge
# It will also setup fresh laravel application, cron and supervisor.
# FYI: This setup is my personalized setup with custom workflows.
# All files are located in: /srv/$USER/apps/$DOMAIN/


# Install LEMP and Node on your server just one click.
curl -fsSL amn.pw/lemp | bash -s -- --domain=example.com --user=example

# Or you can download and run
wget amn.pw/lemp
chmod +x lemp
./lemp --domain=example.com --user=example

# to see help
./lemp --help
