Frp的简介

Frp全名Fast Reverse Proxy，是一个可用于内网穿透的高性能的反向代理应用，主要用于解决一些内网服务没有公网IP但是却需要提供公网访问的问题，使用Frp可以将内网中的TCP、UDP、HTTP、HTTPS等协议类型的应用发布到公网，并且支持web服务根据域名进行路由转发

前期准备

有公网IP的云服务器一台（笔者所用服务器为centos7）
内网服务器一台（可以是家用电脑，我这里使用的是centos7）
Frp服务端和客户端
域名一个（可选）
如果为云服务器，配置安全组，放行相应端口，并关闭服务器防火墙

下载客户端文件

GitHub下载地址根据自己系统版本下载相应文件

解压后的文件目录结构如下

├── frpc  		Frp客户端
├── frpc_full.ini	Frp客户端配置文件模板
├── frpc.ini		Frp客户端配置文件
├── frps		Frp服务端
├── frps_full.ini	Frp服务端配置文件模板

服务端部署，留frps文件
客户端部署，留frpc文件

服务端部署

将frps、frps.ini 拷贝到有公网IP的服务器

[root@zstack root] mkdir /usr/local/frps
[root@zstack root] cp frps* /usr/local/frps

编辑frps.service,将其路径改为实际路径

[Unit]
Description=Frp Server Service
After=network.target

[Service]
Type=simple
User=nobody
Restart=on-failure
ExecStart=/usr/local/frps/frps -c /usr/local/frps/frps.ini
KillSignal=SIGQUIT
TimeoutStopSec=5
KillMode=process
PrivateTmp=true
StandardOutput=syslog
StandardError=inherit

[Install]
WantedBy=multi-user.target

将frps.service移动到systemd目录下，将其注册成服务

[root@zstack root] mv frps.service /usr/lib/systemd/system/

配置frps.ini文件

[common]
#服务器端监听的端口，默认是7000，可自定义
bind_port = 7000
#该端口就是以后访问web服务需要用到的端口
vhost_http_port = 7002

#监控界面配置
#监控界面访问端口
dashboard_port = 7001

#监控界面账户配置，默认值admin
dashboard_user = admin
dashboard_pwd = admin
#日志配置
log_file = ./logs/frps.log
#身份验证token
token = 123456789

启动frps

systemctl start frps
systemctl restart frps
systemctl status frps
systemctl enable frps

客户端部署

将frpc、frpc.ini 拷贝到有内网服务器中

[root@zstack root] mkdir /usr/local/frpc
[root@zstack root] cp frpc* /usr/local/frpc

编辑frpc.service,将其路径改为实际路径

[Unit]
Description=Frp Client Service
After=network.target

[Service]
Type=simple
User=nobody
Restart=on-failure
ExecStart=/usr/local/frpc/frpc -c /usr/local/frpc/frpc.ini
KillSignal=SIGQUIT
TimeoutStopSec=5
KillMode=process
PrivateTmp=true
StandardOutput=syslog
StandardError=inherit

[Install]
WantedBy=multi-user.target

将frpc.service移动到systemd目录下，将其注册成服务

[root@zstack root] mv frpc.service /usr/lib/systemd/system/

配置frpc.ini文件

[common]
#外网-服务器端ip
server_addr = xxx.xxx.xxx.xxx
#外网-服务器端监听的端口(必须与Frps.ini中的配置一致)
server_port = 7000
token = 123456789
#ssh 内网穿透配置
[ssh]
#协议类型为tcp
type = tcp
#映射内网机器IP
local_ip = 127.0.0.1
#内网服务监听的端口
local_port = 22
# 公网映射端口
remote_port = 7003

[rdp]
type = tcp
local_ip = 192.168.13.236
local_port = 3389
remote_port = 7005

[web01]
type = tcp
local_ip = 192.168.13.1
local_port = 80
remote_port = 7004

[web02]
type = http
local_ip = 192.168.13.123
local_port = 5000
custom_domains = 101.132.125.84
locations = /

启动frpc

systemctl start frpc
systemctl restart frpc
systemctl status frpc
systemctl enable frpc
