laravel任务调度go写的程序

#1 编写crontab脚本

#编辑
crontab -e

//最后一行添加下面信息
* * * * * php ~/code/artisan schedule:run >> /dev/null 2>&1

#查看crontab列表
crontab -l

#查看crontab运行情况
tail -f /var/log/syslog | grep CRON

#2 laravel\app\Console\Kernel.php添加运行命令脚本

    /**
     * Define the application's command schedule.
     *
     * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
     * @return void
     */
    protected function schedule(Schedule $schedule)
    {
        if(app()->environment('production')){
            //TODOS

        }
        //test go schedules
        $schedule->exec("cd /var/go/src/schedules && ./log")
            ->everyMinute()
            ->runInBackground();
            //->sendOutputTo(storage_path('logs/go/test.log'));
    }

#3 go文件

package main

import (
	"fmt"
	"log"
	"os"
	"time"
)

func main() {
	log.Fatal(record())
}

func record() error {
	filename := time.Now().Format("log-2006-01-02.text")
	f, err := os.OpenFile("./logs/"+filename, os.O_CREATE|os.O_APPEND|os.O_WRONLY, 0644)
	if err != nil {
		return err
	}
	text := fmt.Sprintf("%s: record something into the logs\n", time.Now())
	_, err = f.WriteString(text)
	if err != nil {
