Embodiment Construction

[0019] The present invention, based on the kernel high-precision timer, reboot command and kernel monitoring module, firstly starts a kernel high-precision timer at the entrance of executing the reboot command (restart command), and at the end of the normal reset process, the CPU is controlled by the user mode application program Register to reset the Linux file system and record the reset reason log. If unsuccessful, 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 expires, the Linux file system is not reset successfully. In the kernel mode, the Linux file system is reset by directly controlling the CPU register, and various reset reasons are recorded to the system log file. The dual protection of user space and kernel space can maximize the reliability of the reboot command to complete the restart. In the case that the Linux file system is damaged and the reboot command cann...

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 reliability of a reboot command and adding a reset log. Background technique [0002] The communication system requires high stability. During system upgrades, equipment engineering openings or troubleshooting, the reboot command is often used to restart the system. The Linux reboot command calls sys_reboot through the api, and finally calls the CPU platform-related function machine_restart to complete 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 services, etc., to protect the Linux file system from damage to the greatest extent, but If an operation hangs or is abnormal, the reboot command will hang all the time. For users, the Linux reboot command causes the system to die, ther...
