# 🚀 铸渊专线V1 · 一键部署脚本
#
# ⚠️ [DEPRECATED · D58] V1节点已停用
# 铸渊专线2.0已测试通过并正式启用，V1节点不再使用。
# V2部署脚本: deploy-brain-proxy.sh (大脑服务器·共享流量池2000GB/月)
# 此文件保留作为V1历史参考，不再部署运行。
#
# 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
