How do I perform load balancing on Linux

Load balancing on Linux is the process of distributing network or application traffic across multiple servers to ensure no single server becomes overwhelmed, improving performance and reliability. Below are various methods and tools to implement load balancing on your Linux servers.

Example using Nginx as a Load Balancer

Nginx is a popular web server that can also function as a robust load balancer. Here's an example of how to configure Nginx for load balancing.

http { upstream my_app { server app_server1.example.com; server app_server2.example.com; server app_server3.example.com; } server { listen 80; location / { proxy_pass http://my_app; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } } }
