在Openwrt中使用cloudflared，可直接使用二进制文件进行配置。自启动相关脚本参考ubuntu下cloudflared service创建的脚本内容修改而来。

配置及脚本

  1. 安装procps-ng-ps
    opkg update && opkg install procps-ng-ps
  2. 下载cloudflared到/usr/bin下，添加可执行权限
  3. 创建Openwrt启动脚本/etc/init.d/cloudflared，配置token，相关内容如下 
    #!/bin/sh /etc/rc.common
# For RedHat and cousins:
# chkconfig: 2345 99 01
# description: cloudflared
# processname: /usr/bin/cloudflared
### BEGIN INIT INFO

# Required-Start:
# Required-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: cloudflared

### END INIT INFO
name=cloudflared
cmd="/usr/bin/cloudflared --pidfile /var/run/$name.pid --autoupdate-freq 24h0m0s tunnel run --token <token>" #replace <token>
pid_file="/var/run/$name.pid"
stdout_log="/var/log/$name.log"
stderr_log="/var/log/$name.err"
[ -e /etc/sysconfig/$name ] && . /etc/sysconfig/$name
get_pid() {
cat "$pid_file"
}
is_running() {
[ -f "$pid_file" ] && ps $(get_pid) > /dev/null 2>&1
}
START=99
start() {
    if is_running; then
        echo "Already started"
    else
        echo "Starting $name"
        $cmd >> "$stdout_log" 2>> "$stderr_log" &
        echo $! > "$pid_file"
    fi
}
stop() {
    if is_running; then
        echo -n "Stopping $name.."
        kill $(get_pid)
        for i in {1..10}
        do
            if ! is_running; then
                break
            fi
            echo -n "."
            sleep 1
        done
        echo
        if is_running; then
            echo "Not stopped; may still be shutting down or shutdown may have failed"
            exit 1
        else
            echo "Stopped"
            if [ -f "$pid_file" ]; then
                rm "$pid_file"
            fi
        fi
    else
        echo "Not running"
    fi
}
  4. 启动服务 /etc/init.d/cloudflared start
