linux架设frp服务
frp（fast reverse proxy）是一个C/S架构的开源服务，可以用来内网穿透远程调试，下面介绍如何架设

架设frp server
1.下载&解压
frp server需要架设在带有公网IP的服务器上，这里我选择假设在azure的VM上（最便宜的VM不到20元/月）
首先下载对应设备的版本解压（当然你也可以下载源码再编译，我这里只是将frp当作一个工具在用，就图方便下载了编译好的）

line1: 下载frp
line18：解压下载的frp
line32-40：frps为server软件，frps.ini为server软件对应的配置文件
2.修改配置文件frps.ini
1 [common] 2 bind_port = 7000
line2: bind_port表示服务器将监听端口号7000，供client链接，这个端口号可以按照需求自行修改
3.启动frp server程序
1 ./frps -c ./frps.ini > ./frps.log &
在frps应用程序所在的文件夹下执行此命令，&表示后台运行
你也可以参照我另一篇博客，将ftps用systemd管理起来，做到开启自启动linux开机自启动frp - 王东力 - 博客园 (cnblogs.com)
架设frp client
1.下载&解压
跟架设frp server一样，ftp client部署在被控设备上（通常是你的编译服务器，或者调试设备），将frp下载到被控设备上解压
2.修改配置文件frpc.ini
1 [common] 2 server_addr = 0.0.0.0 3 server_port = 7000 4 5 [ssh] 6 type = tcp 7 local_ip = 127.0.0.1 8 local_port = 22 9 remote_port = 8822
line2：server_addr对应的是你服务器的公网IP
line3：server_port对应的服务器的端口号，网络编程中TCP端口号
line5：如果部署了有多个frp client，建议中括号中修改为唯一的命名，避免冲突报错[W] [control.go:179] [e7493b2e19556d78] [ssh] start error: proxy name [ssh] is already in use
line7：local_ip即本地IP地址就好，不用修改
line8：local_port这里需要ssh，所以设置为22
line9：remote_port表示frp server将监听这个端口号，一旦发现有链接请求，就映射到被控设备的ssh端口
3.启动frp client程序
1 ./frpc -c ./frpc.ini > ./frpc.log &
上图就是大概架构图,假如我想在PC上远程ssh到frp client B我只需要在PC上执行以下命令：
ssh -p 8822 linux@159.127.127.41
其中linux为client B的用户名
