# think-cron 计划任务
## 安装方法
```
composer require yunwuxin/think-cron
```
## 使用方法
### 创建任务类
```
<?php
namespace app\task;
use yunwuxin\cron\Task;
class DemoTask extends Task
{
public function configure()
{
$this->daily(); //设置任务的周期,每天执行一次,更多的方法可以查看源代码,都有注释
}
/**
* 执行任务
* @return mixed
*/
protected function execute()
{
//...具体的任务执行
}
}
```
### 配置
> 配置文件位于 config/cron.php
```
return [
'tasks' => [
\app\task\DemoTask::class, //任务的完整类名
]
];
```
### 任务监听
#### 两种方法:
> 方法一 (推荐)
起一个常驻进程可以配合supervisor使用
~~~
php think cron:schedule
~~~
> 方法二
在系统的计划任务里添加
~~~
* * * * * php /path/to/think cron:run >> /dev/null 2>&1
~~~
