In this issue, the editor will bring you about how to solve the CVM crash. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

CVM crashes are also divided into a variety of situations. Take Linux system as an example, although it is famous for its open source and stability, there are few problems, but the problem of panic can not be avoided. Let's introduce how to deal with it.

1. First of all, to determine the cause of the crash, generally speaking, the most likely cause of the crash is that the server system is overloaded and runs programs and applications that consume more memory.

At this point, you can switch to the TTY text interface through Ctrl+Alt+F1, type top at the prompt and enter, and you can see which processes and applications consume how many resources. Just type kill to close the program.

two。 In addition to the high load, some underlying software BUG can also cause rare crash problems, so if you don't speed up or still crash after closing the program, you can try to restart the computer.

3. However, there is a situation where the mouse and keyboard do not work because of the death caused by BUG, and it is very irrational to force power off. At this time, you can only restart or shut down safely through the reisub or reisuo command. Press Alt+SysRq on the keyboard, and then enter the letters reisub in turn. When you enter b, the system will restart automatically, and the same input reisuo system will automatically shut down.

SysRq is an instruction requested by the CVM system. After being pressed, everything entered will be handled by the Linux kernel, which allows the user to execute some low-level low-level commands.
