What this article shares with you is the reason why the files on the linux CVM cannot be deleted. The editor thinks it is very practical, so I share it with you. I hope you can learn something after reading this article. Without saying much, let's take a look at it with the editor.

The disk space is full. Because Linux does not have the Recycle Bin function, all files to be deleted on the online server will be moved to the system / tmp directory first, and then the data in the / tmp directory will be cleared periodically.

There is no problem with this strategy, but sometimes it is found that there is no separate / tmp partition in the system partition of the CVM, so the data under / tmp actually takes up the space of the root partition. Then delete some large data files in the / tmp directory.

Correctly empty the linux CVM file

There are many ways to solve this kind of problem, the easiest way is to shut down or restart the httpd process, of course, you can restart the operating system, but these are not the best ways. To deal with the constant logging of files in this process, the best way to free the disk space occupied by files is to empty the file online, which can be done by using the following command:

[your website domain name @ xxx.com ~] # echo "> / tmp/access_log

This method not only frees disk space immediately, but also ensures that the process continues to write logs to files. This method is often used to clean up log files generated by Apache, Tomcat, Nginx and other Web services online.

These are the reasons why the files of the linux CVM cannot be deleted. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
