让服务器每晚运行一个命令，就像 python 中的 cron 作业
我在编写服务器程序时遇到了问题。我需要为套接字设置一个超时，该超时将根据套接字签入的时间每天增加。该程序将为表示自服务器首次运行以来传递的日期的变量+1。该变量将乘以 86,400（一天中的秒数）来设置套接字的超时。
我的问题是，有没有办法运行一个 cron 作业，每隔 2 天执行一次脚本的一部分？有问题的服务器具有可以运行此命令的命令。然而，这将涉及手动交互，这很痛苦。那么，在 python 中，有没有办法让它每天凌晨 4:00 运行一个命令，而不用 while 循环锁定程序呢？
I have run into a problem while writing my server program. I need to set a timeout for a socket that will increase every single day depending on when the socket checks in. The program will +1 to a variable that represents the dates passed since when the server is first run. This variable will than be multiplied by 86,400 (The amount of seconds in a day) to set the timeout for the socket.
My question is, is there a way to run a cron job that will execute a part of a script every say, 2 days? The server in question has commands that can run this. However, that would involve manual interaction which is a pain. So, in python is there a way to make it run a command every day at 4:00 am, without locking the program up with a while loop?

您需要创建一个单独的执行线程来处理要处理的套接字通信。

You need to create a seperate thread of execution for your socket communication to be handled in.
