# ═══ §3 HTTPS 配置 (Xray+Nginx共存架构) ═══════════════════
#
# ⚠️ 重要: 443端口由Xray(VPN)占用，Nginx SSL监听127.0.0.1:8443
#
# 架构说明:
#   外部 443 → Xray (VLESS+Reality协议)
#     ├── 认证VLESS客户端 → 代理上网 (铸渊专线VPN)
#     └── 非VLESS流量 → 回落到 127.0.0.1:8443 (dest参数)
#                          └── Nginx SSL (处理HTTPS网站请求)
#
#   外部 80 → Nginx (HTTP)
#     ├── 域名有SSL证书 → 301重定向到 https://域名 (SSL配置文件处理)
#     └── 域名无SSL证书 → 直接服务网站 (本文件§1/§2)
#
# 证书来源: Let's Encrypt (certbot) · setup-ssl.sh 自动配置
# SSL配置文件: /etc/nginx/sites-available/ssl-{domain}.conf (监听127.0.0.1:8443)
# 部署方式: deploy-to-zhuyuan-server.yml action=setup-ssl
# Xray配置: server/proxy/config/xray-config-template.json (dest: 127.0.0.1:8443)
#
# 注意: 以下旧SSL模板已废弃，仅保留作为参考
# 新SSL配置由 setup-ssl.sh 自动生成到 sites-available/ssl-{domain}.conf
#
# ─── §3.1 [已废弃] 预览域名 HTTPS ───
# 原设计: Nginx直接监听443 · 与Xray冲突 · 已改为8443内部端口
# 新设计: 由 setup-ssl.sh 自动生成 · 监听 127.0.0.1:8443
