#
# 把一台格式化干净的 Ubuntu 22.04 国内 CVM 准备成"光湖灯塔":
#   1. 装基础工具链 (走阿里云镜像源, 国内可达)
#   2. 装 Docker + Compose (跳过 get.docker.com, 用阿里云镜像)
#   3. 在 /data 数据盘下建 Gitea/Postgres/Redis/Runner 标准目录
#   4. 起 Gitea + PostgreSQL + Redis + Gitea Actions Runner
#   5. 部署 Nginx 反代 (Gitea + 灯塔门户 + 总控 API 占位)
#   6. 装 PM2 / certbot / fail2ban / ufw 基础守护
#
# 服务器现状假设 (来自冰朔同步):
#   - 实例: GH-CVM-MAIN-PROD-01 · 4C16G · Ubuntu 22.04
#   - 数据盘: 100GB ext4 已挂载 /data, fstab 自动挂载
#   - 安全组: 22/80/443/3000 已放行
#   - 默认登录用户: ubuntu (本脚本需要 sudo -i 切到 root 后运行)
#
# 用法:
#   sudo CN_LIGHTHOUSE_SERVER_ID=GH-CVM-MAIN-PROD-01 \
#        GITEA_ADMIN_USER=bingshuo \
#        GITEA_ADMIN_PASS=xxx \
#        GITEA_ADMIN_EMAIL=you@example.com \
#        GITEA_DB_PASS=xxx \
#        bash bootstrap.sh
#
# 环境变量:
#   CN_LIGHTHOUSE_SERVER_ID  必填 · 母编号 (GH-CVM-MAIN-PROD-01 / GH-CVM-BACKUP-01)
#   DATA_ROOT                可选 · 默认 /data (持久数据根, 必须挂载)
#   DEPLOY_ROOT              可选 · 默认 /opt/guanghu (代码 / pm2 进程根)
#   GITEA_ADMIN_USER         必填 · Gitea 初始管理员账号
#   GITEA_ADMIN_PASS         必填 · Gitea 初始管理员密码 (≥24 位)
#   GITEA_ADMIN_EMAIL        必填 · 管理员邮箱
#   GITEA_DB_PASS            必填 · PostgreSQL gitea 用户密码
#   GITEA_HTTP_PORT          可选 · 默认 3000
#   GITEA_SSH_PORT           可选 · 默认 2222 (避开系统 22)
#   STAGE                    可选 · bootstrap (默认) / update / rollback
