Frp服务的搭建
搭建frp很简单，关键的步骤只有三步：
1、获取frp文件；
2、设置frp配置文件；
3、启动frp服务。
注意：frp搭建的的这三步是分为客户端和服务端的，但是操作基本是一致的。本教程frp服务的搭建主要介绍frp搭建的主要三步，以及frp服务端和客户端配置文件内容的解释说明，以及如何将frp在linux系统中创建systemd服务，进行服务管理。
第一步：获取frp文件
frp支持linux平台和windows平台。参照你的设置的运行平台下载linux版本的文件或者是windows的。
下载地址：https://github.com/fatedier/frp/releases
一般linux平台下载的版本为：frp_版本号_linux_amd64.tar.gz
windows平台下载的版本为：frp_版本号_windows_amd64.zip
linux版本文件的解压命令为tar zxvf 文件名，windows版本文件直接右键解压即可。
文件解压后，一般都含有frps(frp服务端运行文件)、frpc(frp客户端运行文件)、frps.ini(frp服务端配置文件)、frpc.ini(frp客户端配置文件)，以及frp_full.ini(frp全部配置文件解释说明和参考。)
第二步：frp配置文件设置
frp配置文件分为服务端和客户端，想要正常只用frp工具，我们需要对服务端和客户端的配置文件分别进行设置。

第三步：启动服务
linux环境下启动服务，需要先把运行文件添加可执行权限。
例如我的文件实在root文件夹中，我需要搭建frp服务端，那么待设置好服务端配置文件（frps.ini）后执行以下命令即可：
cd /root
chmod +x frps
nohup ./frps -c ./frps.ini &
执行成功后，会显示frp的进程号码。你也可以通过命令来查看frps运行的进程编号：ps -e | grep frps
在windows环境下则是以管理员身份运行cmd命令提示符。进入相应的目录后，运行命令即可：
frps -c frps.ini &
关于frp管理的优化设置
debian8.0，或者是centos7.0以上的版本，服务都是基于systemd的方式进行管理的。frp通过设置后也可以实现systemd的方式进行管理，这样我们就可以通过systemctl命令来进行服务的统一管理，同时通过这样的设置也可以将frp服务加入开机自启动。
- 将frp设置成linux系统的服务，基于systemd方式管理
编写frp.service文件，以centos7为例：
vim /usr/lib/systemd/system/frps.service
内容如下：
[Unit]
Description=frps daemon
After=syslog.target network.target
Wants=network.target
[Service]
Type=simple
ExecStart=/root/frp/frps -c /root/frp/frps.ini
Restart=always
RestartSec=1min
[Install]
WantedBy=multi-user.target
- 将frp设置成开机自启动
systemctl enable frps
systemctl start frps
- Frp到此就配置完了。
附：个人参考配置
- 服务器端：
[common]
bind_addr = 0.0.0.0 //绑定地址
bind_port = 8888 //TCP绑定端口
bind_udp_port = 8888 //UDP绑定端口
kcp_bind_port = 8888 //KCP绑定端口
vhost_http_port = 80 //HTTP代理端口
vhost_https_port = 443 //HTTPS代理端口
dashboard_addr = 0.0.0.0 //仪表盘地址
dashboard_port = 10000 //仪表盘端口
dashboard_user = admin //仪表盘用户名
dashboard_pwd = admin //仪表盘密码
token = 123456 //连接密码
subdomain_host = test.com //子域名使用的主机名
- 客户端：
[common]
server_addr = 172.16.100.100 //服务器地址
server_port = 8888 //服务器绑定端口
token = 123456 //特权模式密码
[web] //服务名称（自定义）
local_ip = 192.168.10.50 //本机ip
type = http //链路类型
local_port = 80 //本机端口
subdomain = web //服务端为test.com,故此处子域名为web.test.com
custom_domains = demo.com //自定义访问域名，多个使用,分割
use_compression = true //使用压缩
use_encryption = true //使用加密
[ssh] //服务名称（自定义）
local_ip = 192.168.10.50 //本机ip
type = tcp //链路类型
local_port = 22 //本机端口
remote_port = 9000 //远程访问端口
use_compression = true //使用压缩
use_encryption = true //使用加密
