Linux Web Server/Web Application Load Balancing using Nginx

Install and configure the Ingenix load balancer on a Linux server, enable startup, adjust firewall rules, and manage worker processes to load balance content requests to backend web servers.

Install and start the web server, enable it to run at startup, and verify the service status. Open firewall ports, create an index file, and test access in a browser.

Configure nginx load balancing across multiple backend servers with upstream blocks, weights, backups, proxy_pass routing, and location blocks.

Examine Nginx load balancing directives, including default round-robin, least connections, ip hash, and server weighting, with support for persistence via cookies and routing adjustments when a server becomes unavailable.

Configure Nginx http load balancing by defining an upstream group with multiple servers, use round-robin or IP hash, reload config, and test with requests to ensure failover and persistence behavior.

Configure SSL termination at the load balancer to secure end-user to load balancer communication using a certificate and private key, then enable secure back-end connections with client-server authentication.

Configure a secure TLS connection between the load balancer and upstream Nginx servers by deploying trusted certificates and enabling client authentication for encrypted backend traffic.

Configure a tcp/udp load balancer with nginx by defining stream blocks, upstream groups, and proxy_pass to back-end servers on specific ports, including tcp and udp ports such as 53.
