Description

A method and system for quickly installing an operating system

technical field

The invention relates to the technical field of operating system installation, in particular to the technology for installing UNIX operating systems and Linux operating systems.

Background technique

At present, both the UNIX operating system and the Linux operating system have the problem that the installation process is complicated and cannot be installed in batches by cloning.

Take the Solaris operating system in UNIX as an example. At present, there are a large number of servers in the fields of finance, communication and telecommunications using the Solaris operating system, and Solaris 8 and Solaris 10 versions are mostly used.

The installation process of the Solaris operating system is complicated, requiring manual intervention in many places during the installation process, and it is difficult to roll back after an error occurs. Therefore, there are high requirements for engineers who install the Solaris system. Every production and delivery requires Sun to come to the site for commissioning and installation. The installation system ( Including application) takes 8 to 10 hours or more.

As shown in Figure 1, the traditional installation method of the Solaris operating system is to use CD/DVD to install, follow the prompt information during the installation process to operate step by step, and the operation steps in the installation process need to be set.

When installing the Solaris operating system, use CD/DVD for human-computer interaction installation. During the installation process, the engineer will reply to the prompt information, configure relevant parameters, and continue the installation after the configuration is completed. Therefore, the installation of the existing Solaris operating system has the following problems:

(1) There are many human-computer interaction processes during the installation of the operating system, and the operation is complicated. The human-computer interaction process is likely to cause misoperations. After misoperations, it cannot be rolled back and can only be reinstalled. The requirements for installation engineers are relatively high, and professional installation is required.

(2) The installation process takes a long time. Generally, it takes 3 hours or more for a skilled engineer to install a complete operating system. The long installation process prolongs the production cycle and increases the inventory pressure. The delivery cycle is corresponding is stretched.

(3) The installation process cannot be recorded for copying and transplantation, and the installation of the Solaris operating system needs to be repeated.

In addition to the above-mentioned UNIX operating system, the installation process of the Linux operating system also has the same problem.

Installing the Linux operating system can use the same installation process as above. In addition, Ghost software can be used to implement clone installation for the x86 architecture hardware system.

Using Ghost software to install the Linux operating system is a commonly used cloning technology. This solution needs to clone the LINUX operating system installed on the x86 architecture hardware platform, clone the installed Linux system into a mirror file, and then use this mirror file in the same type Clone and install the Linux operating system on the x86 architecture.

However, the above-mentioned cloning installation method can only clone and install the Linux operating system on the x86 architecture hardware platform, and is not suitable for the installation of the UNIX operating system; in addition, the Ghost software is not free software, and additional purchase is required when using this software for cloning installation Ghost software increases production costs or operating costs; at the same time, it is difficult to realize customization requirements when using Ghost software for cloning installation, and there are restrictions when cloning customized systems for applications.

Detailed ways

The basic principle of the present invention is to back up the system information and system data of the installed operating system to the sample memory through the backup program, and then use the operating system information and system data backed up in the sample memory to restore the server of the same model. The operating systems in the sample storage are cloned to servers of the same model, avoiding repeated manual installations on servers of the same model.

In this embodiment, the installation process of the Solaris operating system is used for illustration, which will be described in detail below with reference to the drawings and specific embodiments.

The system structure of the embodiment of the present invention is shown in Figure 2, including:

The server A with the Solaris operating system installed is used for the sample storage to back up the system information and system data of the installed Solaris operating system;

The sample memory is used to back up the system information and system data of the installed Solaris operating system from the server on which the Solaris operating system has been installed, and restore the server to be restored through the recovery program.

The program to be developed includes two parts, one is the system backup program and the other is the system recovery program. The effect of the system backup program is to back up its Solaris system in the tape from an installed server A (hereinafter referred to as the server making the sample tape) system (also can be other sample storage, the embodiment of the present invention uses the tape as Example), the tape for backing up the installed system is called a sample tape. The function of the system recovery program is to treat the operating system partition according to the system partition information backed up in the sample tape, and then restore the system data in the sample tape to the server to complete the quick installation operation.

The above-mentioned system backup program and system recovery program are stored in server A. When the sample memory backs up the installed Solaris operating system in server A, the backup program will back up the system information and system data of the Solaris system in server A to At the same time, backup the recovery program to the sample memory.

When making a sample tape, first use the command ufsdump (used to back up or dump the ufs file system) to back up the system backup program and system recovery program to the first block of the tape. When using the sample tape to restore the system, first use the command ufsrestore (used to restore the ufs file system) to restore the first piece of data in the sample tape, the restored data includes the automatic recovery program, and then execute the automatic recovery program, Complete the cloning operation.

As shown in Figure 2, backing up the installed operating system includes the following steps:

1. Check whether the system meets the backup requirements. If the data in the system has been mirrored or encapsulated by Volume Manager (Symantec volume management software), the backup operation cannot be performed. For those that do not meet the backup requirements, the system will give a prompt message , to end the process.

2. If the system meets the backup requirements, back up the server model information, and use the uname (view Solaris operating system, host name, server type information) command to back up the server model.

3. Use the df (view disk space usage) command and the prtvtoc (output disk partition information) command to back up the system partition information, including the disk partition scheme and partition size, and back up the root partition information.

4. Backup disk quantity and disk size information.

5. Use the ufsdump command to back up the relevant information of the above backup and the recovery program to the tape.

6. According to the system partition information, back up the data in each slice (hard disk partition in the Solaris system) partition to the tape cyclically, and use the ufsdump command to complete the backup operation.

After the backup is completed, the production of the sample tape is completed, and the sample tape can be used for subsequent system recovery operations. After the backup is complete, eject the tape from the tape drive, affix a corresponding label on the tape and save it, which can be used for quick recovery installation of this type of model.

After the sample storage completes the backup of the installed Solaris operating system on the server A, the sample storage can be used to complete the recovery operation of the server whose system is to be restored.

First, you need to copy the recovery program in the sample storage to the server of the system to be recovered. After the recovery program runs, read the system information of the installed Solaris operating system backed up in the sample storage, and partition the system to be recovered according to the partition information. , and then copy the system data stored in the sample storage to the system to be restored in sequence according to the partitions.

Figure 4 shows the process of installing the Solaris operating system using the prepared sample belt, including the following steps:

1. First, prepare the hardware system, including a tape drive capable of reading the sample tape and the prepared sample tape, and connect the tape drive to the server to be restored.

2. Boot the system through the installation CD (CD/DVD).

3. Restore the recovery program of the first block in the sample tape to the temporary directory of the system to be recovered.

4. The restoration program detects whether the model of the system to be restored is consistent with the model backed up in the sample tape, if they are consistent, go to step 5, otherwise go to step 9.

5. The recovery program checks whether the number of hard disks of the system to be restored is less than the number of hard disks of the system for making the sample tape (if the operating system in the system for making the sample tape is installed on three hard disks, and the system to be restored has only one hard disk, then the recovery operation must fail. Another issue is the size of the hard disk. The hard disk capacity of the system to be restored must be greater than or equal to the hard disk capacity of the system for making the sample tape, otherwise the partition cannot be performed, and the system data cannot be fully restored.) If not less than that, go to step 6, otherwise go to step 9.

6. The recovery program partitions the system to be recovered according to the partition information backed up in the sample tape, and creates a file system.

7. Execute the recovery program to restore the system data in the sample tape to the system in sequence according to the partitions.

8. Create a boot block on the root partition, configure device drivers, automatically restart the system, and complete the recovery operation.

9. End.

It takes about 0.5-1 hour to restore the system operation by adopting the above scheme, which greatly shortens the time for installing the Solaris system compared with the manual installation of each system to be restored in the prior art.

Although the implementation of the Solaris operating system is used as an example for illustration in the embodiment of the present invention, the protection scope of the present invention is not limited to the installation of the Solaris operating system, and the technical solution of the present invention is also applicable to the installation of other UNIX and Linux operating systems.
