问题描述
我的 webhotel 上有一个站点，我想在其上运行一些计划任务.您会推荐哪些方法来实现这一目标?
I have a site on my webhotel I would like to run some scheduled tasks on. What methods of achieving this would you recommend?
到目前为止，我想到的是在每个页面的顶部包含一个脚本，然后让该脚本检查是否该运行该作业.
What I’ve thought out so far is having a script included in the top of every page and then let this script check whether it’s time to run this job or not.
这只是我所想的一个简单例子:
This is just a quick example of what I was thinking about:
if ($alreadyDone == 0 && time() > $timeToRunMaintainance) {
runTask();
$timeToRunMaintainance = time() + $interval;
}
还有什么我应该考虑的吗?还有比这更好的方法吗?
Anything else I should take into consideration or is there a better method than this?
推荐答案
这就是 cronjobs 的用途.man crontab 假设您正在运行 Linux 服务器.如果您没有 shell 访问权限或无法设置 cronjobs，可以使用免费服务在外部服务器上设置 cronjobs 并 ping 您的 URL 之一.
That's what cronjobs are made for. man crontab assuming you are running a linux server. If you don't have shell access or no way to setup cronjobs, there are free services that setup cronjobs on external servers and ping one of your URLs.
