# VPN 专线管理平台 启动脚本 // Logan.Li
|
||||
# 单二进制内嵌前端交付：构建前端 → 编译 Go → 启动单二进制
|
||||
# 用法: ./run.sh [build-frontend|build|run|dev|stop|restart|status|help]
|
||||
#
|
||||
# 与 opsx-web-lite 的区别：
|
||||
# - opsx-web-lite 是前后端分离 dev 模式（backend + frontend 独立进程）
|
||||
# - 本项目把前端构建产物 embed 进 Go 二进制，最终 ./opsx-vpn 单文件运行
