Create shell scripts for Linux tasks

I'm looking to get help from a linux expert to get scripts created to help automate common linux server setup tasks. Here are the scripts I am looking to get created: - Server setup - Create user - FTP Setup - Setup option to login using password (with strict requirements) vs SSH key - Setup default home folder to website - Setup proper permissions for website folder so that www-data still owns files after user uploads a file via FTP - Add a ssh key to authorized key - Install nginx and apache (looking for scripts for each server) - Enable PHP - Enable PHP extensions - Options to enable and disable common plugins (mod_rewrite, etc) - Add domain - Create folder and permissions - Add option to add user FTP access to domain - Add subdomain - Create folder and permissions - Add option to add user FTP access to domain - Add Wild-card subdomains - Create folder and permissions - Add option to add user FTP access to domain - Add alias - Site password protection - Ensure permissions on files are correct - Add custom SSL certificate - Add letsencrypt to site - Setup and configure Redis - Add user with permissions - Schedule Backup - Setup and configure MySQL - Add user with permissions - Schedule automated Backup to specified directory - Setup and configure phpmyadmin - Whitelist ip - Setup and configure Supervisord - Configure Cron Job - Run PHP Script - Options to run hourly, daily, weekly, monthly, specific times - Security - Configure fail2ban - Block port scanning - Firewall - Block IP - Block IP ranges - Optional Production Mode for Server - Disable ServerSignature, TraceEnable, Header always unset X-Powered-By, etc. - Disable root account for ssh access - Script to send info to external url using Curl (preferably as json values): - Generate reports on stats - Hard drive usage (size and used) - CPU Usage (# of cores and usage per core) - Memory Usage (amount of RAM and used) - Server Uptime - Certificate monitoring: - Certificate Expiration monitoring - Certificate Chain monitoring - Certificate Domain monitoring - Certificate Authority monitoring - Certificate Transparency monitoring - Updates available - List apps that can be updated - Script to Update Server - Update server and apps - Upgrade PHP to newer version and set apache/nginx to use newer version Requirements: - Scripts should be split out for each task and organized into folders (ideally to match list above) - Use variables and parameters where appropriate to help automate script running (i.e. for creating a user, script should allow passing in user name and password to create) - Each script should be properly commented to explain what is being done
