I need to develop a task system that should be able to work on servers that doesn't support crontab. I'm asking if there is any existing code that can take a cron string (e.g. '0 0,12 1 */2 *' and return the timestamp of the next scheduled run. If such a code couldn't be found then how should I start with that? You could use this class PHP-Parse-cron-strings-and-compute-schedules It'll also compute the last scheduled run Use this function: function parse_crontab($time, $crontab) {$time=explode(' ', date('i G j n w', strtotime($time))); $crontab=explode(' ', $crontab); foreach ($crontab as $k=>

django-crontab执行定时任务

非 Y 不嫁゛ 提交于 2019-11-29 06:51:52
最 近在用django写一下网站,要写一下定时任务,djcelery比较复杂,就使用了django-crontab 摘自: http://www.aiuxian.com/article/p-3187478.html django-crontab实现定时任务 1 django-crontab安装 django-crontab安装: pip install django - crontab django-crontab加入:只需要将 django - crontab 加入到settings.py的 INSTALLED_APPS 即可。如下代码: INSTALLED_APPS = ( 'django_crontab', ... ) 2 django-crontab配置 django-crontab可以定时运行自定义命令和函数两种方式,因为之前尝试用command+crontab时已经实现了自定义command,所以自然而然使用了自定义命令这种形式。 2.1 django-crontab定时运行命令 我先参考 Django官方文档 自定义了一个命令 aizhan_5domain_visits ,专门用于抓取爱站流量,并将结果保存在sqlite3数据库中(具体步骤在本文中不赘述了)。 其次,我在 settings . py 中加入了django-crontab的命令: CRONJOBS =

Starting phantomJS from a script in a cronjob

我只是一个虾纸丫 提交于 2019-11-29 06:50:24

When I run the script normally phantomJS starts as it should, but running it through a script in a cronjob I get this error. What is missing in the cronjob to be able to start phantomjs? Message: 'Unable to start phantomjs with ghostdriver.' ; Screenshot: available via screen Traceback (most recent call last): File "/home/scraper/superfish-extension/chrome_3day.py", line 96, in <module> main() File "/home/scraper/superfish-extension/chrome_3day.py",
