# 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.
# User under which nginx runs
