# Nginx Load Balancer Configuration Template
|
|
#
|
|
# This configuration is designed for use with the Load Balancer Configurator plugin.
|
|
# It provides a basic setup for load balancing across multiple upstream servers.
|
|
#
|
|
# To use this template:
|
|
# 1. Replace the placeholders with your actual server details.
|
|
# 2. Choose the appropriate load balancing method.
|
|
# 3. Test the configuration thoroughly before deploying to production.
|
