Embodiment Construction

[0030] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0031] Embodiments of the invention include:

[0032] First, see figure 1 , a Linux system crash control method, comprising:

[0033] Create a kernel crash analysis thread, and use the Linux command #more / var / log / messages to display the time when the event occurred, the host name of the source system where the event occurred, and the program name that generated the log message, and analyze the cause of the system crash;

[0034] If the kernel crash analysis thread checks out the following display in the system log:

[0035] shutdown:shutting down for system reboot

[0036] init: Switching to runlevel: 6 exiting on signal 15

[0037] Got SIGTE...

Abstract

The invention discloses a Linux system crash control method, which comprises the following steps of: creating a kernel crash analysis thread, and analyzing reasons for crash of a system, namely system crash caused by a user or system crash caused by hardware or system crash caused by software; creating a kernel crash avoidance thread, performing a system crash test experiment caused by software, and triggering system crash caused by the software; reading a log code generated when the system crashes, and writing the log code into the suspended task function for protection and shielding; and packaging the suspended task function into a Linux kernel, restarting the operating system, and entering the Linux kernel again. By means of the mode, the system log can be obtained through the Linux command, the hardware problem and the software problem can be distinguished by analyzing the system log to trigger the crash phenomenon, blockage of the service volume is protected and shielded, the service volume is prevented from being monitored, and when the service access data volume is large, software faults can be avoided.

Description

technical field [0001] The invention relates to the field of system abnormality analysis, in particular to a Linux system crash control method, system and medium. Background technique [0002] When using a server, it is often encountered that the server crashes abnormally or triggers the Linux kernel panic. The cause of the server crash is firstly the hardware problem of the server itself; or the external environment triggers the problem, such as the ambient temperature. If it is too high or too low, the server self-protection threshold is triggered; or it may be the impact of a virus in the external environment, or the server system is down due to task congestion; no matter what kind of phenomenon causes the abnormal restart and downtime, it will affect the Customer experience or customer usage will have an immeasurable impact. [0003] kdump is a tool and service used to dump memory operating parameters when the system crashes, deadlocks or crashes, so that the system wil...
