使用 FRP 内网穿透| 适用于Linux Windows服务端
1、很多情况下处于NAT网络环境中没有公网IP，这个时候可疑通过FRP服务器的转发进行内网穿透。frp内网穿透服务器搭建和frp使用方法。
本教程是使用TCP模式（连接内网Windows的远程桌面），frp客户端和frp服务端以Windows服务的方式在后台默默运行，还可以使用UDP、HTTP、HTTPS模式。
2、为什么不再使用ngork
ngork2.0不再开源

3、Linux服务端安装
wget --no-check-certificate https://raw.githubusercontent.com/clangcn/onekey-install-shell/master/frps/install-frps.sh -O ./install-frps.sh
chmod 700 ./install-frps.sh
./install-frps.sh install
或者手动安装
https://github.com/fatedier/frp/releases/download/v0.16.1/frp_0.16.1_linux_386.tar.gz
https://github.com/fatedier/frp/releases/download/v0.16.1/frp_0.16.1_linux_amd64.tar.gz
tar -zxvf frp_0.16.1_linux_amd64.tar.gz
mv frp_0.16.1_linux_amd64 frp
vi /etc/rc.local
su - root -c "/root/frp/frps -c /root/frp/frps.ini -L /root/frp/frps.log"

https://github.com/fatedier/frp/releases/download/v0.21.0/frp_0.21.0_linux_amd64.tar.gz
tar -zxvf frp_0.21.0_linux_amd64.tar.gz
mv frp_0.21.0_linux_amd64 frp
vi /etc/rc.local
su - root -c "/root/frp/frps -c /root/frp/frps.ini" #这样日志会在/root目录下

4、Windows服务端安装
https://github.com/fatedier/frp/releases
https://github.com/fatedier/frp/releases/download/v0.16.1/frp_0.16.1_windows_386.zip
https://github.com/fatedier/frp/releases/download/v0.16.1/frp_0.16.1_windows_amd64.zip
解压即可

5、frp服务端配置文件，基本包含frps_full.ini全部的配置了
frps.ini
---------------------------------------------------------------------------------------------------
[common]
bind_addr = 0.0.0.0
bind_port = 5443
# udp port used for kcp protocol, it can be same with 'bind_port'
# if not set, kcp is disabled in frps
kcp_bind_port = 5443

# set dashboard_addr and dashboard_port to view dashboard of frps
# dashboard_addr's default value is same with bind_addr
# dashboard is available only if dashboard_port is set
dashboard_addr = 0.0.0.0
dashboard_port = 7500

# dashboard user and pwd for basic auth protect, if not set, both default value is admin
dashboard_user = admin
dashboard_pwd = admin

# assets_dir = ./static
vhost_http_port = 8080
vhost_https_port = 4443
log_file = ./frps.log
# debug, info, warn, error
log_level = info
log_max_days = 30

# privilege mode is the only supported mode since v0.10.0
privilege_token = hLzzySjVo1kMJgaz
# heartbeat configure, it's not recommended to modify the default value
# the default value of heartbeat_timeout is 90
# heartbeat_timeout = 90

# only allow frpc to bind ports you list, if you set nothing, there won't be any limit
#privilege_allow_ports = 1-65535
# pool_count in each proxy will change to max_pool_count if they exceed the maximum value
max_pool_count = 50

# authentication_timeout means the timeout interval (seconds) when the frpc connects frps
# if authentication_timeout is zero, the time is not verified, default is 900s
authentication_timeout = 900

# if subdomain_host is not empty, you can set subdomain when type is http or https in frpc's configure file
# when subdomain is test, the host used by routing is test.frps.com
subdomain_host = frps.com

# if tcp stream multiplexing is used, default is true
tcp_mux = true

服务端简洁配置
[common]
bind_addr = 0.0.0.0
bind_port = 55443
kcp_bind_port = 55443
log_file = ./frps.log
log_level = info
log_max_days = 30
privilege_token = hLzzySjVo1kMJgaz
max_pool_count = 50
tcp_mux = true
authentication_timeout = 900
#frp_0.21会出现下面的错误，FRP 客户端所在机器和 FRP 服务端所在机器的时间相差不能超过 15 分钟
login to server failed: authorization faile
2018/09/27 14:31:15 [W] [service.go:262] authorization failed
-------------------
6、Windows 启动frp服务器
frps.exe -c frps.ini
Windows快速添加通过防火墙规则
netsh advfirewall firewall add rule name="Open Port 5443" dir=in action=allow protocol=TCP localport=5443
netsh advfirewall firewall add rule name="Open Port 5443" dir=in action=allow protocol=TCP localport=6443
netsh advfirewall firewall add rule name="Open Port 4443" dir=in action=allow protocol=TCP localport=4443
netsh advfirewall firewall add rule name="Open Port 23689" dir=in action=allow protocol=TCP localport=23689
netsh advfirewall firewall add rule name="Open Port 8080" dir=in action=allow protocol=TCP localport=8080

Windows 开机自启动frp服务器
控制面板 ---> 管理工具 ---> 任务计划程序

或者运行框输入下面代码，添加启动项 #这样必须登录系统才开始运行服务
%programdata%\Microsoft\Windows\Start Menu\Programs\Startup
-------------------
7、linux 启动frp服务器
frps -c frps.ini

Linux 开机自启动frp服务器
vi /etc/rc.d/rc.local #centos7 chmod +x /etc/rc.d/rc.local
su - root -c "/root/frp/frps -c /root/frp/frps.ini"

vi /etc/rc.local
su - root -c "/root/frp/frps -c /root/frp/frps.ini"
iptables -I INPUT -p tcp -m multiport --dports 55443,55446,55448 -j ACCEPT;service iptables save;service iptables restart
---------------------------------------------------------------------------------------------------
8、客户端配置文件tcp_model
frps.ini
----------
[common]
server_addr = 122.114.xx.xx
