# ===== EternalAI Nginx 反向代理配置 =====
#
# 使用方法:
#   1. 复制到 Nginx 配置目录:
#      sudo cp deploy/nginx.conf /etc/nginx/sites-available/eternalai
#      sudo ln -s /etc/nginx/sites-available/eternalai /etc/nginx/sites-enabled/
#   2. 替换 YOUR_DOMAIN 为实际域名
#   3. 测试配置: sudo nginx -t
#   4. 重载: sudo nginx -s reload
#
# HTTPS 配置（推荐）:
#   sudo certbot --nginx -d YOUR_DOMAIN

# 替换 YOUR_DOMAIN 为你的实际域名
