服务端

以服务端IP地址47.10.13.3为例

配置文件

[root@xx bin]# pwd
/usr/bin
[root@xx bin]# cat frps.ini 
[common]
# frp监听的端口，默认是7000，可以改成其他的
bind_port=5001
# 授权码，请改成更复杂的
token=2022

# frp管理后台端口，请按自己需求更改
dashboard_port = 5000
# frp管理后台用户名和密码，请改成自己的
dashboard_user = admin
dashboard_pwd = admin
enable_prometheus = true

# frp日志配置
log_file = /root/frps.log
log_level = debug
log_max_days = 5

将服务端程序及配置文件放到/usr/bin目录下

[root@xx bin]# pwd
/usr/bin
[root@xx bin]# ll frps*
-rwxr-xr-x 1 root root 14036992 Sep 23 21:37 frps
-rw-r--r-- 1 root root      425 Sep 23 23:53 frps.ini

配置服务端frps服务及开机自动启动服务

[root@xx system]# pwd
/lib/systemd/system
[root@xx system]# cat frps.service 
[Unit]
Description=Frps Server Service
After=network.target
 
[Service]
TimeoutStartSec=30
Restart=on-failure
RestartSec=5s
ExecStart=/usr/bin/frps -c /usr/bin/frps.ini
ExecStop=/bin/kill $MAINPID
ExecReload=/usr/bin/frps reload -c /usr/bin/frps.ini
 
[Install]
WantedBy=multi-user.target

# 重新加载配置文件
systemctl daemon-reload
 
# 启动frpc服务
systemctl start frps
 
# 开机自启动frpc服务
systemctl enable frps
 
# 重启服务
systemctl restart frps

服务启动后，可以通过?http://47.10.13.3:5000 访问frp的管理页面，默认用户名密码都是admin

查看服务状态

客户端

客户端就是连接到任意内网的机器

将客户端程序及配置文件放到/usr/local/bin下

shang@shang-pc:/usr/local/bin$ pwd
/usr/local/bin
shang@shang-pc:/usr/local/bin$ ll frpc*
-rwxr-xr-x 1 root root 10997760 Sep 24 00:50 frpc*
-rw-r--r-- 1 root root      153 Sep 24 00:50 frpc.ini

配置文件

shang@shang-pc:/usr/local/bin$ pwd
/usr/local/bin
shang@shang-pc:/usr/local/bin$ cat frpc.ini
[common]
### 服务端IP地址，一般为公网IP
server_addr = 47.10.13.3
### 服务端端口，接收客户端TCP连接
server_port = 5001
token = 2022

[ssh]
type = tcp
### 客户端内网IP
local_ip = 192.168.0.200
### 客户端端口
local_port = 22
### 服务端会将 5002 端口接收到的TCP数据包转发到客户端的22端口
remote_port = 5002

配置客户端机器的frpc服务及开机自动启动

shang@shang-pc:/lib/systemd/system$ pwd

搭建好内网穿透服务后，就可以通过公网IP访问到内网机器。

在内网机器的主板bios中设置通电自启，再配合一个智能插座，就可以实现远程开机。

内网机器开机后，会启动frpc服务，建立内网穿透连接
