[英]how to set a node-schedule job that it doesn't destroy after server reboot in node js
I made a scheduled job by the following code:我通过以下代码做了一个预定的工作:
const schedule = require('node-schedule');
scheduleAuto1A = schedule.scheduleJob(time, function(){
// do some
});
a user enter the cron job time and it have to work until the user cancel it.用户输入 cron 作业时间,它必须工作,直到用户取消它。 but the problem is:
但问题是:
When i restart my app or reboot server, it destroy.当我重新启动我的应用程序或重新启动服务器时,它会破坏。
How can i make a scheduled job for ever?我怎样才能永远做一个预定的工作?
I took the liberty of editing your phrasing, since you're indeed not talking about cron jobs but a scheduled job within your Node.js process.我冒昧地编辑了您的措辞,因为您确实不是在谈论 cron 作业,而是在您的 Node.js 进程中计划的作业。
You can either你可以
cron
functionality to run that function in a stand-alone script at a schedule (arguably easiest)cron
功能以按计划在独立脚本中运行该功能(可以说是最简单的)cron
functionality to start your script at boot ( @reboot
) (with the caveat that you are then still in charge of making sure you start your service if it shuts down)cron
功能以在启动时启动脚本( @reboot
) (但需要注意的是,如果服务关闭,您仍然负责确保启动服务)You can use Crontab (native linux/unix program) utility to schedule your jobs.您可以使用 Crontab(本机 linux/unix 程序)实用程序来安排您的作业。 If you want to do it via node.js, you can use PM2 (simple and easy).
如果你想通过 node.js 来做,你可以使用 PM2(简单易行)。 Otherwise, you can create systemd script to start your program at startup.
否则,您可以创建 systemd 脚本以在启动时启动您的程序。
