frp内网穿透详解

基础介绍

参考：

• 官方：https://github.com/fatedier/frp
• 官方：概览 | frp (gofrp.org)
• 老版本的中文版手册

是什么？

frp是一个快速反向代理，允许您将位于NAT或防火墙后面的本地服务器暴露给Internet。它目前支持TCP和UDP，以及HTTP和HTTPS协议，使请求能够通过域名转发到内部服务。

为什么使用 frp？

通过在具有公网 IP 的节点上部署 frp 服务端，可以轻松地将内网服务穿透到公网，同时提供诸多专业的功能特性，这包括：

• 客户端服务端通信支持 TCP、KCP 以及 Websocket 等多种协议。
• 采用 TCP 连接流式复用，在单个连接间承载更多请求，节省连接建立时间。
• 代理组间的负载均衡。
• 端口复用，多个服务通过同一个服务端端口暴露。
• 多个原生支持的客户端插件（静态文件查看，HTTP、SOCK5 代理等），便于独立使用 frp 客户端完成某些工作。
• 高度扩展性的服务端插件系统，方便结合自身需求进行功能扩展。
• 服务端和客户端 UI 页面。

原理

看下官方的架构：frp 主要由 客户端(frpc) 和 服务端(frps) 组成，服务端通常部署在具有公网 IP 的机器上，客户端通常部署在需要穿透的内网服务所在的机器上。

通俗理解：frps 服务端有点像接线员【具备公网IP】的角色，frpc客户端就好比家里的座机【只有局域网IP，但可以主动访问互联网】，当我们在外部使用公共电话拨打时，先到接线员这里，要求转接到某某座机【就是端口】，接线员就从座机列表中【管理的客户端连接池】，找到对应的座机，转接过去，这样就完成了从外部互联网访问内部服务器的过程。

对应到本项目的架构如下：

使用示例

• 通过 SSH 访问内网机器
• 通过自定义域名访问内网的 Web 服务
• 转发 DNS 查询请求
• 转发 Unix 域套接字
• 对外提供简单的文件访问服务
• 为本地 HTTP 服务启用 HTTPS
• 安全地暴露内网服务
• 点对点内网穿透

关于配置文件说明

推荐使用 TOML, YAML, JSON 这3种格式，目前还支持 INI 格式，但未来是会被删除的。

Since v0.52.0, we support TOML, YAML, and JSON for configuration. Please note that INI is deprecated and will be removed in future releases. New features will only be available in TOML, YAML, or JSON. Users wanting these new features should switch their configuration format accordingly.

Read the full example configuration files to find out even more features not described here.

Examples use TOML format, but you can still use YAML or JSON.

内网穿透实施

远程运维本地虚拟机

服务端配置

1. 从官网下载对应版本和操作系统的安装包；

   

2. 通过rz上传到云服务器中，使用tar命令解压即可。

   # 转义控制符，从宿主机读取文件到服务中
   rz -e
   # 解压软件
   tar -xvf frp_0.52.3_linux_amd64.tar.gz

3. 使用vi frps.toml编辑frps的配置文件 frps.toml，进行配置：

   # frps的通信端口
   bindPort = 7100
   # 与frpc通信的认证方式和token值
   auth.method = "token"
   auth.token = "12345dfFDFERDFDF678"
   
   # 面板的端口、账号和密码
   webServer.addr = "0.0.0.0" #注意该参数
   webServer.port = 7600
   webServer.user = "mfc_test"
   webServer.password = "xxxxxxxxfdsafdae"

   • 特别说明下 0.0.0.0和127.0.0.1的区别：

    0.0.0.0：
    在网络通信中，0.0.0.0是一个特殊的IP地址，被称为"通配符地址"或"任意地址"。
    当一个网络接口绑定到0.0.0.0时，它表示该网络接口将接受来自任何IP地址的所有数据包。
    在服务器配置中，将服务绑定到0.0.0.0意味着该服务将监听其所在计算机上的所有可用网络接口，以接受来自任何源IP地址的连接请求。
   
    127.0.0.1：
    127.0.0.1是一个保留的IPv4回环地址，通常称为"本地主机"或"回环地址"。
    当你的计算机尝试通过网络协议访问127.0.0.1时，数据包不会通过物理网络接口发送，而是在计算机本地内部传输。
    127.0.0.1通常用于本地主机上部署的服务之间进行通信，例如本地开发环境中的Web服务器与数据库之间的通信。
   
    总结：
    0.0.0.0表示接受来自任何源IP地址的数据包，适用于网络通信和服务器配置。
    127.0.0.1是本地主机地址，用于本地主机上的本地通信，适用于回环测试和本地开发环境。

4. 运行frp的服务端 :

   ./frps -c frps.toml
   # 一般会使用 nohup命令，后台运行：
   nohup ./frps -c frps.toml &

   

5. 验证下frps启动情况：

   

注意服务器的防火墙配置：

• 方案1：关闭防火墙【不推荐】

systemctl stop firewalld #关闭防火墙
systemctl disable firewalld #开机禁用

• 方案2：将我们需要的端口开放出去

firewall-cmd --state ##查看防火墙状态，是否是running
systemctl start firewalld #启动防火墙
systemctl enable firewalld #开机启用 
firewall-cmd --add-port=7100/tcp --permanent ##永久添加 7100 端口
firewall-cmd --add-port=7600/tcp --permanent ##永久添加 7600 端口
firewall-cmd --add-port=6001/tcp --permanent ##永久添加 7100 端口
firewall-cmd --reload #重新载入配置，比如添加规则之后，需要执行此命令
firewall-cmd --zone=public --list-ports ##查看已开放的端口

客户端配置

1. 和服务端类似，上传并解压软件。

2. 编辑客户端frpc的配置文件 frpc.toml：

   user = "fc"
   # frps的地址和通信端口
   serverAddr = "47.92.25.139"
   serverPort = 7100
   # 与frps通信的认证方式和token值
   auth.method = "token"
   auth.token = "12345dfFDFERDFDF678"
   
   [[proxies]]
   name = "ssh_local_linux01"
   type = "tcp"
   localIP = "127.0.0.1"
   localPort = 3389
   # If remotePort is 0, frps will assign a random port for you
   remotePort = 6001

3. 启动客户端配置：

   ./frpc -c frpc.toml
   # 一般会使用 nohup命令，后台运行：
   nohup ./frpc -c frpc.toml &

systemd 管理 frp 实践

1. 如Linux服务端上没有安装 systemd，可以使用 yum 或 apt 等命令安装 systemd

   # yum
   yum install systemd
   # apt
   apt install systemd

2. 使用文本编辑器，如 vim 创建并编辑 frps.service 文件。

   vi /etc/systemd/system/frps.service

3. 写入内容：

   [Unit]
   # 服务名称，可自定义
   Description = frp server
   After = network.target syslog.target
   Wants = network.target
   [Service]
   Type = simple
   # 启动frps的命令，需修改为您的frps的安装路径
   ExecStart = /opt/software/frp/frps -c /opt/software/frp/frps.toml
   [Install]
   WantedBy = multi-user.target

4. 使用 systemd 命令，管理 frps。

   # 启动frp
   systemctl start frps
   # 停止frp
   systemctl stop frps
   # 重启frp
   systemctl restart frps
   # 查看frp状态
   systemctl status frps
   # 配置 frps 开机自启
   systemctl enable frps
   # 禁止开机启动
   systemctl disable frps

5. 配置 frpc的开启启动也类似，服务名改为/etc/systemd/system/frpc.service，启动命令修改为 frpc的即可。

   [Unit]
   # 服务名称，可自定义
   Description = frp client
   After = network.target syslog.target
   Wants = network.target
   [Service]
   Type = simple
   # 启动frpc的命令，需修改为您的frpc的安装路径
   ExecStart = /opt/software/frp/frpc -c /opt/software/frp/frpc.toml
   [Install]
   WantedBy = multi-user.target
