frp 是一个可用于内网穿透的高性能的反向代理应用,支持 tcp, udp 协议,为 http 和 https 应用协议提供了额外的能力,且尝试性支持了点对点穿透。

1. 架构

frp

2. 代理结构

frps部署在服务端(局域网1),并能够对外网暴露端口。frpc部署在客户端(局域网2),但是不能对外暴露端口。

为了让局域网1能够访问局域网2的内部服务,所以需要将局域网2的服务代理到局域网1。这样,局域网1就像访问内网的一样访问局域网2。

代理成功之后,也可以将代理的端口在局域网1暴露到公网上,使得,公网能够访问局域网2。

frp

3. 前提条件

  1. frps服务端必须能够暴露公网端口。
  2. frpc能够连接外网。

4. 配置

5. 服务化

frpc.service

[Unit]
Description=frp: frp is a fast reverse proxy to help you expose a local server behind a NAT or firewall to the internet. As of now, it supports tcp & udp, as well as http and https protocols, where requests can be forwarded to internal services by domain name.
Documentation=https://github.com/fatedier/frp

[Service]
ExecStart=/opt/frp/frpc -c /opt/frp/frpc.ini
Restart=always
StartLimitInterval=0
RestartSec=10
