# TAXIDO — cPanel App Setup (shared hosting)
# ==============================================================================
# Runs ONLY the Laravel app-level steps. No root, no apt, no nginx/mysql-server,
# no supervisor, no ufw. cPanel already provides PHP, MySQL and the web server.
#
# Before running:
#   1. In cPanel > MySQL Databases: create a database + user, add user to DB
#      with ALL PRIVILEGES. Note the names (they are usually prefixed, e.g.
#      cpaneluser_taxido).
#   2. In cPanel > MultiPHP Manager (or Select PHP Version): set this domain to
#      PHP 8.2 or 8.3, and enable extensions: mbstring, xml, curl, zip, bcmath,
#      intl, gd, pdo_mysql, fileinfo, openssl.
#   3. Point the domain/subdomain Document Root to  <this folder>/public
#      (Domains > manage > Document Root). Do NOT expose the project root.
#
# Run from the project root:   bash cpanel-install.sh
# ==============================================================================
