Embodiment Construction

[0019] The present invention, based on the kernel high-precision timer, reboot command and kernel monitoring module, first starts a kernel high-precision timer at the entrance of executing the reboot command (restart command), and at the end of the normal reset flow, controls the CPU through the user mode application program Register to reset the Linux file system, and record the reset reason log. If it fails, call the default code of the reboot command to execute the Linux file system reset, and record the reset reason log. When the kernel high-precision timer times out, the Linux file system is not reset successfully. In the kernel mode, the Linux file system reset is completed by directly controlling the CPU registers, and various reset reasons are recorded in the system log file. The double protection of the user space and the kernel space can maximize the reliability of the reboot command to complete the restart. When the Linux file system is damaged and the reboot command...

Abstract

The invention discloses a method for improving the reboot command restart reliability and increasing reset logs.The method includes the steps that a kernel monitoring module is added and loaded, a kernel timer is initialized, and the reset monitor timeout time is set; after a reboot command is received, a reset script is executed; within the timeout time, reset cause logs are recorded through a user mode reset system at the end of reset script execution, and if reset fails, the reboot command is executed to reset the system, and the reset cause logs are recorded; if system reset fails after timeout, a kernel mode reset system records the reset cause logs.The timer is started to monitor reset by increasing user mode application programs and kernel mode reset control protection, the reset cause logs are increased for query, the kernel monitoring module is controlled to reset the system when the reboot command cannot reset the system due to system anomaly, system reset measures are increased, and the robustness and maintainable management capability of the system are improved.

Description

technical field [0001] The invention relates to Linux system management and fault diagnosis, in particular to a method for improving the restart reliability of a reboot command and increasing reset logs. Background technique [0002] The communication system requires high stability. During system upgrades, equipment engineering activation, or troubleshooting, it is often necessary to use the reboot command to restart the system. The Linux reboot command calls sys_reboot through the api, and finally calls the function machine_restart related to the CPU platform. reboot. [0003] Before restarting, the Linux file system will execute the script / etc / rc6.d / S01reboot to complete the safe uninstallation of the file system, the exit of the application process, and the safe stop of the service, etc., so as to protect the Linux file system from damage to the maximum extent, but If a certain operation hangs or is abnormal, the reboot command will always hang. For the user, it is the ...
