Webinoly is built on the LEMP stack—a powerful combination of Linux, Nginx, MySQL/MariaDB, and PHP that provides a robust foundation for hosting websites and applications.

​
What is LEMP?

LEMP is an acronym for the four core components:
  • Linux: The operating system (Ubuntu 20.04, 22.04, or 24.04)
  • Engine-x (Nginx): The web server
  • MySQL/MariaDB: The database management system
  • PHP: The server-side scripting language
The “E” in LEMP comes from the pronunciation of Nginx as “Engine-x”.

​
Stack components

​
Nginx web server

Webinoly installs and optimizes Nginx as the primary web server with:
  • HTTP/2 and HTTP/3 support: Modern protocol support for improved performance
  • TLS 1.2 and 1.3: Secure SSL/TLS connections with modern ciphers
  • kTLS (Kernel TLS): Hardware-accelerated encryption on Ubuntu 22.04+
  • Rate limiting: Protection against DDoS attacks and brute force attempts
  • Gzip compression: Automatic compression of text-based content
The stable branch is recommended for production environments and provides long-term stability.
sudo stack -nginx -nginx-ppa=stable

​
PHP-FPM

PHP is installed with FastCGI Process Manager (FPM) for optimal performance: Supported versions: 7.4, 8.0, 8.1, 8.2, 8.3, 8.4, 8.5 Default version: 8.4 (as of Webinoly 1.20.0) Pre-installed extensions:
  • Core: CLI, FPM, Common, cURL, GD, Readline, Mbstring, Bcmath, XML, Intl
  • Database: MySQL/MySQLi
  • Caching: OPcache (bundled in PHP 8.5+), Msgpack, Igbinary
  • File handling: Zip, Imap
  • Other: Soap, Imagick
Webinoly automatically optimizes PHP settings based on your server’s available resources.
Process management: 
# Process manager modes
pm = dynamic          # Default (calculated based on resources)
pm.max_children = 10  # Maximum number of child processes
pm.start_servers = 3  # Initial number of processes
pm.min_spare_servers = 3
pm.max_spare_servers = 6

​
MySQL/MariaDB

Choose between MySQL or MariaDB as your database engine:
Default choice - Open-source, MySQL-compatible database serverSupported versions: 10.11, 11.4, 11.8 (LTS releases)Default version: 11.8
sudo stack -mysql -mysql-ver=11.8
Choose your database engine before installation. Switching between MySQL and MariaDB after installation requires a complete reinstallation.

​
Installation profiles

Webinoly offers multiple installation profiles to suit different needs:

​
Full stack

Complete LEMP stack with all features: 
sudo webinoly -lemp
Includes:
  • Nginx (web server)
  • PHP-FPM (latest stable version)
  • MySQL/MariaDB (database server)
  • Let’s Encrypt (SSL certificates)
  • Backup tools (Duplicity + Duply)
  • Redis (object caching)
  • Memcached (alternative caching)
  • phpMyAdmin (database management)
  • Postfix (email delivery)

​
Basic stack

Core LEMP components plus SSL and backups: 
sudo webinoly -basic
Includes:
  • Nginx
  • PHP-FPM
  • MySQL/MariaDB
  • Let’s Encrypt
  • Backup tools
  • Postfix

​
Light stack

Minimal LEMP installation: 
sudo webinoly -light
Includes:
  • Nginx
  • PHP-FPM
  • MySQL/MariaDB

​
Individual components

Install components separately: 
# Install only Nginx
sudo stack -nginx

# Install only PHP
sudo stack -php

# Install only MySQL/MariaDB
sudo stack -mysql

# Add Redis later
sudo stack -redis

​
Optimizations

Webinoly automatically optimizes the LEMP stack based on your server resources:

​
Resource-based tuning

  • Worker processes: Set to number of CPU cores (worker_processes auto)
  • Worker connections: Up to 20,000 concurrent connections per worker
  • PHP-FPM pool: Calculated based on available RAM
  • File descriptors: Optimized for high traffic (worker_rlimit_nofile)
  • FastCGI cache: 90% of /run folder size allocated for caching

​
Security hardening

  • Server tokens disabled (version information hidden)
  • Unnecessary PHP functions disabled by default
  • Session security configured (HTTPOnly, Secure, SameSite)
  • File upload restrictions enforced
  • DH parameters generated (2048-bit)

​
Performance tuning

  • OPcache enabled and optimized
  • Open file cache configured
  • TCP optimizations (tcp_nopush, tcp_nodelay)
  • Sendfile enabled for efficient file serving
  • Connection timeouts optimized

​
Configuration file

All LEMP stack settings can be customized in /opt/webinoly/webinoly.conf: 
# Edit configuration
sudo nano /opt/webinoly/webinoly.conf

# Apply changes
sudo webinoly -server-reset
See the Configuration file documentation for all available settings.

​
Verification

Check the status of your LEMP stack: 
# Full system verification
sudo webinoly -verify

# Check specific services
sudo systemctl status nginx
sudo systemctl status php8.4-fpm
sudo systemctl status mysql

​
Admin tools

Webinoly provides a special admin tools site accessible on port 22222:
  • Nginx status: Server status and metrics
  • PHP info: PHP configuration and loaded extensions
  • PHP status: PHP-FPM pool status and statistics
  • Redis/Memcached: Object cache status (if installed)
# Access admin tools
http://your-server-ip:22222

# Change admin tools port
sudo webinoly -tools-port=8080
Admin tools are protected with HTTP authentication by default. Keep these credentials secure.
