Abstract

The invention discloses a Linum system repairing method. The method includes following steps: A, providing a physical server and installing a Linum system, backing up a master boot sector related information onto other systems or equipment; B, zero-setting a partition table of a system disc to simulate a scene where a Linux server in a production environment may damage the partition table duo to virus or accidental shutdown of the system; and C, restoring an operation system and disc data by repairing the partition table of the system disc. By the Linux system repairing method, failure of the Linux system can be effectively repaired, so that system safety and data safety of the Linux server are guaranteed, restoring time of the Linux system is shortened, and usability of the Linux system is improved. The Linum system repairing method is suitable for Linux systems such as RedHat, Debian, SUSE and Gentoo.

Description

technical field [0001] The invention relates to the field of computer and information technology, in particular to a method for repairing a Linux system. Background technique [0002] Linux has won the favor of the majority of enterprises and is widely used for its free, good security, reliable system security, and openness. However, the security of the platform is not equal to the security of the data. During the use of Linux, due to abnormal shutdown Or virus infection, etc., which lead to the damage of the hard disk DPT (Disk Partition Table, that is, the partition table), so that the data in the disk is lost or damaged, causing huge losses. [0003] MBS (Master Boot Sector, that is, the master boot sector of the disk), the function of MBS checks whether the DPT is correct and determines which partition is a bootable partition, and transfers the startup program of the partition into the memory for execution at the end of the program. Please refer to figure 1 As shown, M...
