Installation[edit]
apt install nginx-light systemctl status nginx /var/www/html/
Docker Nginx https://hub.docker.com/_/nginx
Nginx Sample Configurations[edit]
Features[edit]
Nginx can be deployed to serve dynamic HTTP content on the network using FastCGI, SCGI handlers for scripts, WSGI application servers or Phusion Passenger modules, and it can serve as a software load balancer.[1]
Nginx uses an asynchronous event-driven approach, rather than threads, to handle requests.[2] Nginx's modular event-driven architecture can provide more predictable performance under high loads.[3][4]
Nginx default configuration file is nginx.conf
.[5]
HTTP proxy and Web server features[edit]
- Ability to handle more than 10,000 simultaneous connections with a low memory footprint (~2.5 MB per 10k inactive HTTP keep-alive connections)
- Handling of static files, index files and auto-indexing
- Reverse proxy with caching[6] (
proxy_pass
directive) (Do not support proxy [7]) - Load balancing with in-band health checks[8] (
upstream
directive) - TLS/SSL with SNI and OCSP stapling support, via OpenSSL
- FastCGI, SCGI, uWSGI support with caching
- gRPC support since March 2018, version 1.13.10.[9]
- Name- and IP address-based virtual servers
- IPv6-compatible
- WebSockets since 1.3.13,[10][11] including acting as a reverse proxy and do load balancing of WebSocket applications.[12]
- HTTP/1.1 Upgrade (101 Switching Protocols),[13] HTTP/2 protocol support
- URL rewriting and redirection[14][15]
Mail proxy features[edit]
- TLS/SSL support
- STARTTLS support
- SMTP,[16] POP3, and IMAP proxy
- Requires Authentication using an external HTTP server or by an authentication script[17][18]
Other features include upgrading executable and configuration without client connections loss,[19] and a module-based architecture with both core[20] and third-party module support.[21]
The paid Nginx Plus product includes additional features such as advanced load balancing and access to an expanded suite of metrics for performance monitoring.[22][23]
Linux Nginx Operation on systemd distributions[edit]
- Verify/Test Configuration:
nginx -t
- Status:
systemctl status nginx
- Start:
systemctl start nginx
- Stop:
systemctl stop nginx
- Restart:
systemctl restart nginx
(See also:nginx -t
)
Activities[edit]
- Track Application Response time in Nginx
- Enable status page in Nginx to get information about active connections and other parameters: https://easyengine.io/tutorials/nginx/status-page/ and test it:
curl http://127.0.0.1/nginx_status
- Read Nginx Change log
- Configure HTTP to HTTPs redirection with Nginx
- Review SSL nginx configuration
Medium
- Use
prometheus-nginx-exporter
to collect Nginx metrics - Use metricbeat to collect metrics, see:
metricbeat modules list
