【问题描述】:
我正在使用最新版本的 Homestead。 我也设置了 Laravel Horizon。 我使用 Redis 作为队列驱动程序。 Laravel 是 5.6 版,是全新安装。
发生的事情是我的作业都失败了(即使作业正确退出)。
我正在使用自定义命令通过命令行运行作业:
vagrant@homestead:~/myapp$ artisan crawl:start
vagrant@homestead:~/myapp$ <-- No CLI errors after running
app/Console/Command/crawl.php
<?php
namespace MyApp\Console\Commands;
use Illuminate\Console\Command;
use MyApp\Jobs\Crawl;
class crawl extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'crawl:start';
/**
* The console command description.
*
* @var string
*/
protected $description = 'Start long running job.';
/**
* Create a new command instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* @return mixed
*/
public function handle()
{
Crawl::dispatch();
}
}
app/Jobs/Crawl.php
<?php

use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
class Crawl implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
/**

*
* @var int
*/
public $timeout = 3600;
/**

*

*/
public $tries = 1;
/**
* Create a new job instance.
*
* @return void
*/
public function __construct()
{
}
/**
* Execute the job.
*
* @return void
*/
public function handle()
{
$crawl = new Crawl();
$crawl->start();
}
}
app/Crawl.php
<?php
namespace MyApp;
class Crawl
{
public function start()
{
ini_set('memory_limit','256M');
set_time_limit(3600);
echo "Started.";
sleep(30);
echo "Exited.";
exit();
}
}
worker.log

概要
看看我的worker.log,我可以看到我的课程的输出有效:
Started.
Exited.
但是作业被报告为失败。为什么?
奇怪的是,同样在worker.log,它说Processing 两次为一份工作:
[2018-03-21 10:15:59][1] Processing: MyApp\Jobs\Crawl
[2018-03-21 10:15:59][1] Failed: MyApp\Jobs\Crawl
非常感谢任何帮助!
更新
删除exit() 已解决问题 - 这很奇怪,因为 PHP 手册说您可以使用 exit()“正常”退出程序:
<?php
//exit program normally
exit;
exit();
exit(0);
