CPU requirements are modest, with any modern processor capable of handling Nginx efficiently. Storage considerations depend on your intended use case, but allocating at least 10GB of free space ensures room for web content, logs, and system updates.
Software Prerequisites
A fresh AlmaLinux 10 installation provides the ideal starting point for Nginx deployment. Root access or a user account with sudo privileges is essential for installing packages and modifying system configurations. Basic familiarity with Linux command-line operations will help you navigate the installation process more effectively, though this guide provides detailed explanations for each step.
Network Considerations
Web server functionality requires specific network ports to be available and properly configured. Port 80 handles standard HTTP traffic, while port 443 manages HTTPS connections for SSL-encrypted communications. Planning your firewall configuration in advance prevents connectivity issues and ensures secure access to your web services.
System Preparation
Proper system preparation forms the foundation of a successful Nginx installation. Taking time to update packages, install necessary build tools, and configure user accounts prevents common issues and establishes security best practices from the beginning.
Updating the System
Begin by ensuring your AlmaLinux 10 system has the latest security patches and package updates. Open a terminal and execute the following command to refresh package repositories and install available updates:
sudo dnf update -yThis command updates all installed packages to their latest versions, addressing security vulnerabilities and compatibility issues that might affect Nginx installation or operation. The process may take several minutes depending on the number of available updates and your internet connection speed.
Installing Essential Build Tools
AlmaLinux 10 requires specific development tools and libraries to compile software from source code successfully. Install the Development Tools group package and essential libraries using these commands:
sudo dnf groupinstall "Development Tools" -y
sudo dnf install wget tar gcc make zlib zlib-devel openssl openssl-devel libpcre2 libpcre2-devel -yThese packages provide crucial functionality for Nginx compilation and operation. The gcc compiler handles source code compilation, while zlib enables gzip compression features. OpenSSL libraries support SSL/TLS encryption for secure HTTPS connections, and PCRE2 libraries enable regular expression processing for URL rewriting and request filtering.
Creating Dedicated Nginx User
Security best practices recommend running web services under dedicated system accounts with minimal privileges. Create a non-login system user specifically for Nginx processes:
sudo useradd --system --no-create-home --shell /sbin/nologin nginxThis command creates a system user named ‘nginx’ without a home directory or login shell, preventing unauthorized access while providing the necessary user context for Nginx worker processes.
Installation Method 1: Package Manager Installation
The package manager approach offers the simplest and most straightforward method for installing Nginx on AlmaLinux 10. This method handles dependency resolution automatically and integrates seamlessly with system package management tools.
Installing via DNF Package Manager
AlmaLinux 10 uses the DNF package manager, which provides access to Nginx through the default repositories. Install Nginx using this simple command:
sudo dnf install nginx -yThis command downloads and installs the latest Nginx version available in the AlmaLinux repositories, along with all required dependencies. The installation process typically completes within a few minutes, depending on your internet connection speed and server performance.
Package manager installations offer several advantages including automatic dependency management, easy updates through standard system maintenance procedures, and integration with system service management tools. However, repository versions may not always include the absolute latest Nginx features or security updates.
Using EPEL Repository for Latest Version
The Extra Packages for Enterprise Linux (EPEL) repository often provides more recent Nginx versions than default AlmaLinux repositories. Install the EPEL repository and then install Nginx:
sudo dnf install epel-release -y
sudo dnf install nginx -yEPEL repositories maintain packages that complement the base AlmaLinux distribution without conflicting with core system components. This approach provides access to newer Nginx versions while maintaining system stability and compatibility.
Starting and Enabling Nginx Service
After successful installation, configure Nginx to start automatically at system boot and begin running immediately:
sudo systemctl start nginx
sudo systemctl enable nginxThe first command starts the Nginx service immediately, while the second ensures Nginx launches automatically during system startup. Verify the service status using:
sudo systemctl status nginxA properly configured Nginx service displays an “active (running)” status with process information and recent log entries.
Installation Method 2: Source Code Installation
Installing Nginx from source code provides maximum control over features, modules, and system integration. This method enables custom configurations and optimization for specific use cases, though it requires more technical knowledge and manual maintenance.
Downloading Nginx Source Code
Navigate to a suitable working directory and download the latest Nginx source code from the official repository:
cd /usr/local/src
sudo wget https://nginx.org/download/nginx-1.28.0.tar.gz
sudo tar -zxvf nginx-1.28.0.tar.gz
cd nginx-1.28.0Always verify the latest version number on the official Nginx website before downloading. The /usr/local/src directory provides a standard location for source code compilation, keeping downloaded files organized and easily accessible.

sudo chmod 644 /etc/nginx/nginx.confThese permissions prevent unauthorized access to configuration files and log directories while maintaining proper functionality for Nginx processes. Regular security audits and updates help maintain system integrity over time.
Basic Nginx Configuration
Understanding Nginx configuration structure enables effective customization and optimization for your specific requirements. The main configuration file controls global settings, while server blocks define individual virtual host configurations.
Understanding Configuration Structure
Nginx configuration follows a hierarchical structure with nested context blocks. The main configuration file located at /etc/nginx/nginx.conf contains global settings affecting the entire server:
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
include /etc/nginx/conf.d/*.conf;
}This configuration establishes fundamental server behavior including worker process management, logging settings, and performance optimizations.
Creating Server Blocks
Server blocks define virtual hosts for serving different websites or applications. Create a basic server block configuration:
server {
listen 80;
listen [::]:80;
server_name example.com www.example.com;
root /var/www/html;
index index.html index.htm;
location / {
try_files $uri $uri/ =404;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}This configuration defines a basic virtual host listening on port 80 for the specified domain names. The document root directory contains website files, while location blocks control request handling and error page responses.
Testing Configuration Syntax
Always validate configuration changes before applying them to prevent service disruptions:
sudo nginx -tThis command performs syntax checking on all configuration files, reporting any errors or warnings. Only reload Nginx configuration after confirming syntax validity:
sudo systemctl reload nginxTesting and Verification
Thorough testing ensures your Nginx installation functions correctly and provides the expected service quality. Multiple verification methods help identify potential issues and confirm proper configuration.

Access your Nginx server through a web browser using your server’s IP address or domain name. A successful installation displays the default Nginx welcome page containing server information and basic usage instructions. Alternatively, use command-line tools for testing:
curl -I http://localhostThis command retrieves HTTP headers from the local server, confirming Nginx responds to requests correctly. Expected output includes status code 200 and server identification headers indicating successful operation.
Service Status Verification
Monitor Nginx service status and performance using systemctl commands:
sudo systemctl status nginxActive services display detailed status information including process IDs, memory usage, and recent log entries. Pay attention to any error messages or warnings that might indicate configuration issues or resource constraints.
Examine log files for additional diagnostic information:
sudo tail -f /var/log/nginx/access.log
sudo tail -f /var/log/nginx/error.logAccess logs record all incoming requests, while error logs capture system messages and configuration problems. Regular log monitoring helps identify performance bottlenecks and security concerns.
Advanced Configuration Options
Advanced Nginx configurations enable enhanced security, improved performance, and extended functionality for production environments. These optimizations address specific requirements and operational challenges.
SSL/TLS Certificate Setup
Secure HTTP connections require SSL/TLS certificates for encryption and authentication. Configure HTTPS support using Let’s Encrypt certificates or commercial SSL providers:
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name example.com www.example.com;
ssl_certificate /etc/ssl/certs/example.com.crt;
ssl_certificate_key /etc/ssl/private/example.com.key;
ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256;
ssl_prefer_server_ciphers on;
location / {
root /var/www/html;
index index.html;
}
}
server {
listen 80;
listen [::]:80;
server_name example.com www.example.com;
return 301 https://$server_name$request_uri;
}This configuration enables secure HTTPS connections while redirecting HTTP traffic to encrypted channels.
Performance Optimization
Implement performance enhancements to improve response times and resource utilization:
worker_processes auto;
worker_connections 1024;
http {
gzip on;
gzip_vary on;
gzip_min_length 1024;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
open_file_cache max=1000 inactive=20s;
open_file_cache_valid 30s;
open_file_cache_min_uses 2;
open_file_cache_errors on;
keepalive_timeout 65;
client_max_body_size 64M;
}These optimizations enable compression, file caching, and connection management improvements that reduce bandwidth usage and server load.
Troubleshooting Common Issues
Effective troubleshooting requires systematic problem identification and resolution strategies. Understanding common installation and configuration issues helps maintain reliable Nginx operations.
