Scheduled tasks (crontab) under Linux

If you are an expert, please skip it. . It will make you laugh

This is a tutorial for beginners to apply Linux scheduled tasks. It is relatively simple. If your scheduled tasks are more complex, it is recommended to use shell scripts, etc.

1. Install crontab. I directly use yum install crontab (if you don’t support yum, you can download the installation package and install it)

2. crontab -e will open this 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 1 minute

Execute every five minutes */5 * * * *

Execution every hour 0 * * * *

Execution every day 0 0 * * *

Execution every week 0 0 * * 0

Execution every month 0 0 1 * *

Execution every year 0 0 1 1 *

The specific command execution methods, I will not introduce them one by one here, there are many more
