Laravel调度程序无法按预期工作

twi*_*oid 11 php cron scheduler scheduled-tasks laravel

我在laravel中构建了一个应用程序，该应用程序假设每4小时使用webhose.io获取所有国家的新闻。它似乎可以正常工作一段时间。但是停止并在一段时间后重新启动。我不知道如何跟踪出了什么问题。

Laravel版本

Laravel Framework 5.5.45

Ubuntu 16.04.5 LTS（GNU / Linux 4.4.0-142-通用x86_64）

CRON职位详情 

# Edit this file to introduce tasks to be run by cron.
# 
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
# 
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').# 
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
# 
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
# 
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
# 
# For more information see the manual pages of crontab(5) and cron(8)
# 
# m h  dom mon dow   command

withoutoverlapping()我发现随着时间的推移添加了日志，我发现新闻更新任务每4小时运行一次，但其他任务却使我感到困惑。

简单来说，当CRON守护进程每分钟调用 php artisan schedule:run 命令时，控制台内核将启动，您在App\Console\Kernel::schedule()方法中定义的作业将注册到调度程序中。

该schedule()方法将一个实例Illuminate\Console\Scheduling\Schedule作为唯一参数，这是用于记录您提供给它的作业的调度管理器，并决定每次 CRON 守护程序 ping 它时应该运行什么。

现在转向你的问题。

正如@hoseinz3 提到的几乎是正确的

Laravel 如何防止您的预定作业重叠？

有时，计划作业的运行时间比我们最初预期的要多，这会导致该作业的另一个实例启动，而第一个作业尚未完成，例如假设我们运行一个每分钟生成一个报告的作业，之后有时当数据变得巨大时，报告生成可能需要 1 分钟以上，因此该作业的另一个实例开始时第一个仍在进行中。

在大多数情况下，这很好，但有时为了保证正确的数据或防止高服务器资源消耗，应该防止这种情况。

Laravel 将检查 Console\Scheduling\Event::withoutOverlapping 类属性，如果它设置为 true，它将尝试为作业创建互斥锁，并且只有在可以创建互斥锁时才会运行该作业。

有关互斥锁的更多信息

因此，Laravel 在作业第一次启动时创建了一个互斥锁，然后每次作业运行时它都会检查互斥锁是否存在，如果不存在则只运行作业。

因此，Laravel 创建了一个过滤回调方法，如果互斥锁仍然存在，它会指示计划管理器忽略该任务，它还创建了一个后回调，在任务实例完成后清除互斥锁。

试试这个片段

尝试某种 CRON 作业监控系统。你可以试试 Eyewitness，这是一个很好的监控Laravel 应用程序的工具。

hos*_*nz3 2

您已经使用了withoutOverlapping基于 Laravel 文档的方法，这意味着当一项作业需要很长时间才能运行时，Laravel 默认情况下会保留新作业 24 小时，之后，如果没有作业运行，它会尝试运行该作业，您也可以更改通过withoutOverlapping参数传递这个数字。例如

$schedule->command('command')->hourly()->withoutOverlapping(5);

这意味着 Laravel 将新命令保留 5 小时，如果之后有正在运行的命令，它将尝试再次运行该命令。
