frp简介
概览
frp 是一个专注于内网穿透的高性能的反向代理应用，支持 TCP、UDP、HTTP、HTTPS 等多种协议。可以将内网服务以安全、便捷的方式通过具有公网 IP 节点的中转暴露到公网。
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
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。
内网服务由于没有公网 IP，不能被非局域网内的其他用户访问。
用户通过访问服务端的 frps，由 frp 负责根据请求的端口或其他信息将请求路由到对应的内网机器，从而实现通信。

找到github项目中的releases :https://github.com/fatedier/frp/releases ,下载对应主机的架构版本,此处我是x86_64位的系统,所以下载 [frp_0.34.1_linux_amd64.tar.gz]
解压缩下载的压缩包，将其中的 frpc 拷贝到内网服务所在的机器上，将 frps 拷贝到具有公网 IP 的机器上，放置在任意目录。

FRP 默认提供了 2 个服务端配置文件，一个是简化版的 frps.ini，另一个是完整版的 frps_full.ini。初学者只需用简版配置即可，在简版 frps.ini 配置文件里，默认设置了监听端口为 7000，你可以按需修改它。
服务端
[root@frps frps]# cat frps.ini
[common] #一些常用配置
bind_port = 7000 #frps监听的端口
vhost_https_port = 443 #支持虚拟主机的方式,此处为https,监听443端口
#vhost_http_port = 8080 #支持虚拟主机的方式,此处为http,监听8080端口
authentication_method = token #客户端与服务端的认证方式为token
token = xxx #token为xxx
#dashboard相关配置
dashboard_addr = 0.0.0.0 #监听的地址
dashboard_port = 7500 #监听端口
dashboard_user = admin #dashboard的认证账号
dashboard_pwd = admin #dashboard的认证密码
#以上各个端口不能冲突客户端
[root@frpc /opt/frpc]# cat frpc.ini
[common] #连接服务端的配置
server_addr = frp.chongking.com #此处为服务端ip或解析到服务端的域名
server_port = 7000 #服务端监听的端口
token = xxx #认证token,同服务端token
#以下为需要代理的服务
[ssh] #名称自定义
type = tcp #代理的类型 tcp | udp | http | https | stcp | xtcp, default is tcp
local_ip = 127.0.0.1 #需要代理的主机
local_port = 22 #需要代理的端口
remote_port = 6000 #此服务在服务端的端口,此端口将会在服务端监听.
[mysql]
type = tcp
local_ip = 127.0.0.1
local_port = 3306
remote_port = 3306
[web01]
type = https #代理的协议为https
local_ip = 192.168.199.153 #需要代理的主机为其它主机
local_port = 5001
custom_domains = frp.chongking.com #访问此域名的https服务将会被代理到此服务上
启动frp服务
编写好配置文件后，先通过 ./frps -c ./frps.ini 启动服务端，再通过 ./frpc -c ./frpc.ini 启动客户端。如果需要在后台长期运行，建议结合其他工具使用，例如 systemd 和 supervisior。
#退出终端,并且放后台运行
#服务端
nohup ./frps -c ./frps.ini &
#客户端
nohup ./frpc -c ./frpc.ini &如果是 Windows 用户，需要在 cmd 终端中执行命令。
