# server/proxy/deploy-proxy.sh
# 🚀 铸渊专线 · 一键部署脚本
#
# 在SG服务器上执行，完成代理服务的完整部署:
#   1. 安装Xray-core + BBR
#   2. 生成密钥
#   3. 配置Xray (从环境变量或密钥文件读取)
#   4. 配置Nginx反代
#   5. 启动PM2服务
#   6. 健康检查
#
# 用法:
#   bash deploy-proxy.sh install    — 首次安装
#   bash deploy-proxy.sh update     — 更新配置
#   bash deploy-proxy.sh status     — 检查状态
#   bash deploy-proxy.sh restart    — 重启所有服务
# ═══════════════════════════════════════════════

# 注意: 不使用 set -e，关键步骤手动检查错误
