1. Server FRPS installation and configuration

Download FRP:

version=`curl --silent "https://api.github.com/repos/fatedier/frp/releases/latest" | grep -Po '"tag_name": "\K.*?(?=")'` 
v=`echo $version|grep -Po 'v\K(.*)'`
curl -sSL https://github.com/fatedier/frp/releases/download/$version/frp_"$v"_linux_amd64.tar.gz

FRPS server installation:
You need a machine or cloud server with a public IP. I use an Alibaba Cloud server, and a machine with a public IP (cloud server, etc.) installs the server frps

tar -vxzf frp_0.50.0_linux_amd64.tar.gz
ls frp_0.50.0_linux_amd64

frpc                    # 客户端二进制文件
frpc_full.ini           # 客户端配置文件完整示例
frpc.ini                # 客户端配置文件
frps                    # 服务端二进制文件
frps_full.ini           # 服务端配置文件完整示例
frps.in1                # 服务端配置文件

cp frps /usr/bin/
mkdir /etc/frp
cp frp*.ini /etc/frp

Configure the startup file of frps:

vim /etc/systemd/system/frps.service

Wants=network.target
[Service]
Type=simple

allow_ports = 2000-3000,22,4000-50000
max_pool_count = 50

2. Client FRPC installation and configuration

2.1. Linux system client

Download FRP:

version=`curl --silent "https://api.github.com/repos/fatedier/frp/releases/latest" | grep -Po '"tag_name": "\K.*?(?=")'` 
v=`echo $version|grep -Po 'v\K(.*)'`
curl -sSL https://github.com/fatedier/frp/releases/download/$version/frp_"$v"_linux_amd64.tar.gz

If the intranet server you want to be penetrated is a Windows server, you need to download the corresponding Windows installer

Installation of FRPC server:

tar -vxzf frp_0.50.0_linux_amd64.tar.gz
cd frp_0.50.0_linux_amd64

cp frpc /usr/bin/
mkdir /etc/frp
cp frp*.ini /etc/frp

Configure the startup file of frpc:

vim /etc/systemd/system/frpc.service

2.2. Windows system client

Download frp_0.50.0_windows_amd64.zipthe software package
and configure the startup file of frpc:

[common]
server_addr = 121.43.34.197			
server_port = 7000					
authentication_method = token
token = 1qaz@2wsx						
tls_enable = true
