# 服务端启动
./frps -c frps.ini
# 客户端启动
./frpc -c frpc.ini

Explain

frp实现的本质就是客户端与服务端建立长连接, 从而实现内网穿透的效果.

建立未加密的链接

Server

服务端开启一个端口用于与反向代理的服务器进行连接.

# DetailedErrorsToClient defines whether to send the specific error (with debug info) to frpc. By default, this value is true.
detailed_errors_to_client = true

# authentication_method specifies what authentication method to use authenticate frpc with frps.
# If "token" is specified - token will be read into login message.
# If "oidc" is specified - OIDC (Open ID Connect) token will be issued using OIDC settings. By default, this value is "token".
authentication_method = token

# auth token
token = 12345678

dashboard 是服务端的可视化面板.

可以打开一个dashboard查看端口连接情况.

Client

客户端只要与服务端成功连接, 就可以在服务端上暴露本地的端口.

相当于所有知道端口的终端都可以进行匿名访问.

# tcp | udp | http | https | stcp | xtcp, default is tcp
type = tcp
local_ip = 127.0.0.1
local_port = 22
remote_port = 8000

admin 是客户端的可视化面板, 可以修改配置文件.

这里的[ssh]中括号内的名称可以随意定义, 没有影响, 下文会有影响.

注意: 可视化面板绑定的IP, 0.0.0.0允许通过内网IP访问, 而127.0.0.1只能本机访问.

建立加密的链接

对于不想让任何人都可以访问的服务, 可以建立stcp连接.
