使用 frp 通过云厂商公网IP实现内网穿透
写在前面
- 有小伙伴推荐,简单了解
- 博文内容涉及 内网穿透 工具 frp 的安装以及2个Demo
- 内网的静态文件服务访问 Demo
- 内网多端口映射 Demo
- 理解不足小伙伴帮忙指正
不必太纠结于当下,也不必太忧虑未来,当你经历过一些事情的时候,眼前的风景已经和从前不一样了。——村上春树
公有云上面租一台机器
配置 hostname
修改 PS1

type = "static_file"
# 本地文件目录,对外提供访问
localPath = "/tmp"
# URL 中的前缀,将被去除,保留的内容即为要访问的文件路径
stripPrefix = "static"
httpUser = "abc"
httpPassword = "abc"

这里需要注意部分端口可能浏览器不能识别为 web 服务,比如 6000 ,可能需要更换端口 8099

端口范围映射
客户的配置文件中添加下面的配置,重新加载
{{- range $_, $v := parseNumberRangePair "6000-6006,6007" "6000-6006,6007" }}
[[proxies]]
name = "tcp-{{ $v.First }}"
type = "tcp"
localPort = {{ $v.First }}
remotePort = {{ $v.Second }}
{{- end }}
这会映射 6000-60007 这8 个端口
