Nginx vs Apache 2026: Welchen Webserver wählen?

Nginx und Apache sind die am weitesten verbreiteten Webserver der Welt.

Architektur

Der architektonische Unterschied bestimmt die Leistung.

Apache: Prozess/Thread-basiert

Apache verwendet eine MPM-Architektur.

Apache Architecture (Process/Thread Model):

  Master Process
  ├── Worker Process 1
  │   ├── Thread 1 → handles connection A
  │   ├── Thread 2 → handles connection B
  │   └── Thread N → handles connection C
  ├── Worker Process 2
  │   ├── Thread 1 → handles connection D
  │   └── Thread N → handles connection E
  └── Worker Process N...

  MPM Modes:
  - prefork: 1 process per connection (safe for non-thread-safe modules like mod_php)
  - worker:  threads within process pool (more efficient)
  - event:   listener thread for keep-alive (best for Apache 2.4+)

Nginx: Ereignisgesteuert

Nginx verwendet eine asynchrone Architektur.

Nginx Architecture (Event-Driven):

  Master Process (reads config, manages workers)
  ├── Worker Process 1 (single thread, event loop)
  │   └── Event Loop: handles 1000s of connections via epoll/kqueue
  │       ├── Connection A (non-blocking I/O)
  │       ├── Connection B (non-blocking I/O)
  │       ├── Connection C (non-blocking I/O)
  │       └── ... (thousands more)
  ├── Worker Process 2 (single thread, event loop)
  │   └── Event Loop: handles 1000s more connections
  └── Worker Process N (typically = CPU cores)

  Key: No thread-per-connection overhead
  Result: 10K+ connections with ~30-50MB RAM

Konfigurationsvergleich

Grundlegend unterschiedliche Ansaetze.

Apache: .htaccess

Verteilte Konfiguration via .htaccess.

# Apache Virtual Host Configuration (/etc/apache2/sites-available/example.conf)
<VirtualHost *:80>
    ServerName example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/example/public

    <Directory /var/www/example/public>
        AllowOverride All
        Require all granted
        Options -Indexes +FollowSymLinks
    </Directory>

    # Enable mod_rewrite
    RewriteEngine On
    RewriteCond %{HTTPS} off
    RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

    # PHP via mod_php (prefork MPM required)
    <FilesMatch \.php$>
        SetHandler application/x-httpd-php
    </FilesMatch>

    # Or PHP via PHP-FPM (recommended with event MPM)
    <FilesMatch \.php$>
        SetHandler "proxy:unix:/run/php/php8.3-fpm.sock|fcgi://localhost"
    </FilesMatch>

    # Logging
    ErrorLog ${APACHE_LOG_DIR}/example-error.log
    CustomLog ${APACHE_LOG_DIR}/example-access.log combined
</VirtualHost>

# .htaccess file (per-directory, no restart needed)
# /var/www/example/public/.htaccess
RewriteEngine On
RewriteBase /
RewriteRule ^index\.html$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.html [L]

}

Sicherheitsvergleich

Beide haben gute Sicherheitsbilanzen.

Security Aspect          Apache                    Nginx
-----------------------------------------------------------------
CVE History              More CVEs (larger surface)  Fewer CVEs (smaller codebase)
.htaccess Risk           Can expose config errors    N/A (no .htaccess)
Default Config           Permissive                  Restrictive
Module Surface           Large (many loaded)          Minimal (compile what you need)
Rate Limiting            mod_ratelimit               limit_req / limit_conn (native)
WAF Integration          mod_security (mature)        ModSecurity + NAXSI
Access Control           .htaccess / <Directory>      allow/deny directives
Request Size Limits      LimitRequestBody             client_max_body_size
