Crontab in linux)

: This article mainly introduces the linux scheduled task (crontab). If you are interested in the PHP Tutorial, refer to it. If you are a master, skip this step .. Make You Laugh

This is a linux scheduled task tutorial for beginners. it is relatively simple. if your scheduled task is complex, we recommend using shell scripts, etc,

1. install crontab. I apply yum install crontab directly (if the yum kids shoes are not supported, you can download the installation package and install it)

2. crontab-e opens the scheduled task file.

3. write the corresponding command in it, for example: */1 *****/usr/bin/curl 127.0.0.1/app/sundry/test // execute this url every minute

Run */5 * every five minutes ****

0 *** per hour ****

Execute 0 0 every day ***

Execute 0 0 every week ** 0

0 0 1 per month **

Execute 0 0 1 1 * every year *

The specific command execution methods are not described here.
