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
