用 frp 一键穿透动态 IP 本地服务，秒开公网访问

[common]
server_addr = 你的服务端IP
server_port = 7000
token = your-secret-token   # 要和 frpc.ini 中一致

[web]
type = tcp
local_ip = 127.0.0.1
local_port = 8080   # 本地服务器端口
remote_port = 8081 

./frpc -c frpc.init

nano frpc.init
[common]
bind_port = 7000

# Dashboard 可选
dashboard_port = 7500
dashboard_user = admin
dashboard_pwd = admin
dashboard_addr = 0.0.0.0

# token 验证（防止其他人连接你的 frps）
token = your-secret-token

./frpc -c frps.init

sudo nano /etc/systemd/system/frps.service
