Automated Linux Server Setup

This project provides a fully automated Bash script to set up a production-ready Linux server or Docker stack on Debian, Ubuntu, CentOS, or RHEL. The script installs and configures all essential components for web hosting and applications.

Features

• Operating Systems: Debian 12+, Ubuntu 20.04+, CentOS 7+, RHEL 7+

• Installed Components:

  • Nginx (web server)
  • PHP-FPM (configurable version, e.g., 8.2)
  • MariaDB / MySQL-compatible
  • phpMyAdmin
  • Node.js 20+
  • Fail2Ban (brute-force protection)
  • Firewall (UFW on Debian/Ubuntu, firewalld on CentOS/RHEL)
  • SSL certificates via Certbot (Let's Encrypt)

• Modes:

  • native: installation directly on the host server
  • docker: Docker Compose stack with DB, Nginx, PHP-FPM, phpMyAdmin

• Multi-Domain Support: single or multiple domains can be configured simultaneously

• Automatic Nginx vhosts for each domain

• Non-interactive MariaDB setup with root password

• Docker support for instant containerized deployment

Requirements

• Root access on the server (sudo)
• At least 1 GB RAM
• Internet connection
• Optional: domains pointing to the server

Installation

1. Download the script

curl -fsSL https://example.com/automated-linux-server-setup.sh -o automated-linux-server-setup.sh
chmod +x automated-linux-server-setup.sh

2. Native Installation (without Docker)

sudo DOMAINS="example.com,www.example.com" \
     EMAIL="[email protected]" \
     MODE=native \
     DB_ROOT_PASS="securepassword" \
     bash automated-linux-server-setup.sh

3. Docker Installation

sudo DOMAINS="example.com" \
     MODE=docker \
     DB_ROOT_PASS="securepassword" \
     bash automated-linux-server-setup.sh

After execution, the Docker Compose stack is located under /opt/<domain>.

Configuration

• Web root: /var/www/<domain_group>/html (native) or /opt/<domain>/www (docker)
• MariaDB: Root password is set automatically, default user root
• phpMyAdmin: Access via /phpmyadmin or port 8080 for Docker
• Nginx vhosts: automatically generated for each domain group
• PHP-FPM Socket: /var/run/php/php<version>-fpm.sock (native)

Options

• --domains - comma-separated domains
• --mode - native or docker (default: native)
• --email - administrator email for SSL
• --db-root-pass - MariaDB root password
• --php - PHP version (default: 8.2)
• --force - overwrite existing configurations

Security Measures

• Fail2Ban to protect against brute-force attacks
• Firewall configuration (UFW/firewalld) on standard ports
• SSL certificates via Let's Encrypt
• Non-interactive MariaDB setup removes insecure defaults

Next Steps

1. Place your website files in the web root: /var/www/<domain>/html or /opt/<domain>/www
2. Check Nginx configuration: nginx -t
3. Check PHP-FPM: systemctl status php<version>-fpm
4. Access MariaDB: mysql -u root -p
5. Access phpMyAdmin: http://<domain>/phpmyadmin (native) or http://<server_ip>:8080 (Docker)

Support & Issues

If you encounter problems, please open an issue on GitHub or contact the administrator.

Note: The script is intended for production environments. Test it first in a safe environment. Optional adjustments can include specific security policies, SELinux, load balancers, or CI/CD integration.
