With it, you can configure certain commands or scripts to run periodically over a set period of time. Cron is one of the most useful tools in Linux or Unix-like systems.

You've been doing Windows development before, and Linux is required in recent projects. As a small rookie, hurriedly bought a classic book "Bird Brother's Linux private dishes" study. Recently there was a small task- because the product generated a lot of log, and grew fast, so you need to use the script (Bash scripts) to delete the expired log file .Using cron job under Linux can be a good solution to this problem.　　What is a

A few days ago the friend said his station consumes the cloud bean to be formidable, then sees the log to discover most is the visit cron.php. And then is not the intranet IP access, and also did not add monitoring and so on, it is estimated that the malicious visit by others. But feel that the modification of the name is also somewhat unsafe, the IP blacklist effect will not be very strong. Because IP can be changed at any time, so I added a piece o

The format of the Quartz cron expression is very similar to that of the UNIX cron format, but there is a slight difference. One of the differences is that the Quartz format supports the plan down to the second level, while the UNIX cron program only supports up to the minute level. Many of our trigger plans are incremented based on the second level (for example,

Linux's implementation of php's scheduled cron task does not have a solution for PHP itself to execute the scheduled task, but it is completed by using the sleep function. In this way, you need to make some configuration in advance, such as the implementation process: The code is as follows:Ignore_user_abort (); // close the browser and run the PHP script.Set_time_limit (0); // use set_time_limit (0) to allow unlimited execution of the program$ Inte

In linux, php regularly executes cron tasks. There is no solution for PHP itself to execute scheduled tasks, but it is completed by using the sleep function. This approach requires some configuration in advance, such as the implementation process: copying code does not have a solution for PHP itself to execute scheduled tasks, but it is completed by using the sleep function. In this way, you need to make some configuration in advance, such as the impl

There is no solution for PHP itself to execute scheduled tasks, but it is completed by using the sleep function. In this way, you need to make some configuration in advance, such as the implementation process: (); (0); =60*30; (); }(); However, I have some concerns about the performance of this method, but it is also a temporary method. I recommend that you use scripts to implement it. By using the scheduled task mechanism of the OS itself, windows will use bat scripts. Howev

function Introduction Cron is a timed distributed timed task service that ACE provides to developers, and can perform related tasks on a regular basis as required. For example, back.php periodically queries the database for specific messages to be aggregated to the developer. Cron's grammar rules are consistent with the syntax rules of the crontab under Linxu, but the difference with Crontab's configuration file defines

Because Cron is a built-in service for Linux, it does not automatically get up and you can start and close this service in the following ways: /sbin/service crond Start//boot service /sbin/service Crond Stop//Off service /sbin/service crond Restart//Restart service /sbin/service Crond Reload//Reload Configuration
