Croon

Croon是一个PHP版本的CronTab实现

之前也做过一个类似的实现php-crontab，Croon与之不同的是：使用进程管理方式Fork工作进程；有友好的日志模块；加入事件驱动；更佳规范和稳定

功能：

• 兼容CronTab语法
• 精确到秒级控制
• PSR标准
• 支持事件绑定
• 支持日志

依赖

• PHP 5.3.9+
• ext-pcntl
• ext-posix
• Composer

库依赖（使用composer install自动安装）

• pagon/childprocess
• pagon/eventemitter
• pagon/logger
• pagon/argparser

安装

下载使用：

Latest Release

Git:

git clone git://github.com/hfcorriez/croon.git
cd croon
composer install

Composer

composer require croon/croon

使用

基本用法

croon.list

* * * * * * ls -l >> /tmp/ls.log

# 兼容系统crontab
* * * * * pwd >> /tmp/pwd.log

执行

./bin/croon croon.list -l croon.log

croon.log

[2013-04-20 14:07:01] 27a6c9 -  debug   - Croon...!!!
[2013-04-20 14:07:01] 27a6c9 -   info   - Execute (ls >> /tmp/ls.log)
[2013-04-20 14:07:01] 27a6c9 -   info   - Finish (ls >> /tmp/ls.log)[0]

以mysql数据库为计划任务源

• 修改数据库连接信息 bin/croon_with_mysql
• 表结构为

+---------------------+--------------------------------------------------------+
| time                | command                                                |
+---------------------+--------------------------------------------------------+
| [秒] 分 时 日 月 周   | command                                                |
+---------------------+--------------------------------------------------------+

执行

./bin/croon_with_mysql -l croon.log

高级用法

bootstrap.php

<?php

// 绑定启动事件
$croon->on('run', function() use($croon) {
    // 注入db
    $croon->db = new \PDO('mysql://localhost:3306;dbname=reports');
});

// 绑定执行事件
$croon->on('executed', function ($command, $output) use ($croon) {
    // 记录执行结果
    $croon->db->exec(sprintf(
        'INSERT INTO cron(command, status, stdout, stderr, create_time) VALUES ("%s", "%s", "%s", "%s", "%s")',
        $command, $output[0], $output[1], $output[2], date('Y-m-d H:i:s'))
    );
});

执行

./bin/croon croon.list -l croon.log -b bootstrap.php
