Openwrt+CloudFlare Tunnels 搭建隧道实现无端口访问内网服务

前提

需要绑定一个域名，切换dns服务器，并等待域名激活

SSH登录Openwrt

执行命令下载运行包

curl -L --output cloudflared-linux-arm https://github.com/cloudflare/cloudflared/releases/download/2024.4.1/cloudflared-linux-arm

根据官方提供的选择即可 https://github.com/cloudflare/cloudflared/releases

执行命令

chmod +x cloudflared-linux-arm
mv cloudflared-linux-arm /usr/bin/cloudflared

新增自启动文件

touch /etc/init.d/cloudflared
chmod +x /etc/init.d/cloudflared

编辑文件内容

vim /etc/init.d/cloudflared

文件内容如下：

#!/bin/sh /etc/rc.common

USE_PROCD=1
START=95
STOP=01

cfd_init="/etc/init.d/cloudflared"
cfd_token="这里改成教程004:你复制好的token"

boot()
{
    ubus -t 30 wait_for network.interface network.loopback 2>/dev/null
    rc_procd start_service
}

start_service() {
    if [ $("${cfd_init}" enabled; printf "%u" ${?}) -eq 0 ]
    then
        procd_open_instance
        procd_set_param command /usr/bin/cloudflared --no-autoupdate tunnel run --token ${cfd_token}
        procd_set_param stdout 1
        procd_set_param stderr 1
        procd_set_param respawn ${respawn_threshold:-3600} ${respawn_timeout:-5} ${respawn_retry:-5}
        procd_close_instance
    fi
}

stop_service() {
    pidof cloudflared && kill -SIGINT `pidof cloudflared`
}

token来自于cloudflare，新建隧道时自动生成

启动

/etc/init.d/cloudflared enable
/etc/init.d/cloudflared start

设置域名与内网地址即可访问

结果

访问不稳定，时不时就掉，还很慢
