Method for controlling server startup sequence

The present invention relates to a method for controlling the startup sequence of a server, and more particularly to a method for controlling the startup sequence of a server through a readable and writable mobile storage device.

At present, with the rapid development and popularity of network technology, the Internet has become the preferred tool for people to obtain information and communicate in their daily work and life. In the network, the server can be used to provide various services for the client (such as: allowing or restricting access to shared resources, automatically backing up data, and accessing job data from a remote computer).

In the field of server management, in some cases, the management software requires the target server to perform network startup through a preloaded execution environment (PXE) or virtual media (Virtual Media) to perform certain management tasks. In order to be able to boot the server over the network, various schemes have been developed to control the startup sequence of the server. Among them, the pre-loading execution environment (PXE) is an extension of the remote program load (RPL) technology in the network technology. It is used when the computer itself does not have a booting system, or when there is no hard disk at all. The remote server performs booting and uses the remote system. The preloaded execution environment can also be used to perform system or application installation via the remote server.

Among them, the conventional methods for controlling the startup sequence of the server mainly include the following Several: The first solution: setting the target server, so that the default state of the network card is started, and then controlling the server program preloaded into the execution environment to determine whether to make the target server preloaded. The execution environment is started.

The second solution: the startup sequence is changed in the operating system by the utility provided by the basic input/output system (BIOS) of the target server.

The third solution: through the management of the wafer, such as the motherboard control manager (BMC) to achieve the control of the basic output of the server into the system.

The fourth scheme: changing the startup sequence of the server by controlling the remote ISO file pointed to by the virtual medium.

However, among the above four solutions, the first solution has the drawback that it is necessary to completely control the servo program preloaded into the execution environment, and the defects of the second solution, the third solution and the fourth solution are that the requirements for the hardware are more high.

All in all, the various solutions in the prior art still have the following defects: first, because of the higher requirements for the hardware, the cost increases; second, because of the need for the hardware and operating system of the server. Changes, resulting in reduced security; third, due to the complexity of the program is not easy to implement.

In order to solve the problems and defects in the above prior art, an object of the present invention is to provide a method for controlling the startup sequence of a server, which controls the startup sequence of the server through the readable and writable mobile storage device.

The method for controlling the startup sequence of the server provided by the present invention controls the startup sequence of the target server by the management server through the readable and writable mobile storage device, wherein the control method includes: making a boot image, The boot image is used to start the operating system of the target server, and the first proxy server is placed in the boot image, and the first proxy server is used to communicate with the management server; on the readable and writable mobile storage device Recovering the boot image containing the first proxy server program, so that the readable and writable mobile storage device has the ability to start the target server; installing and running the second proxy server program in the hard disk booting operating system of the target server, The second proxy server program is used for communication with the management server; the basic input and output system of the target server is set, so that the target server first selects to start from the readable and writable mobile storage device, when the removable storage cannot be read from here. When the device starts, it starts from the hard disk of the target server; and the first proxy server or the first The proxy server modifies the boot file in the readable and writable mobile storage device according to the startup command received from the management server, so that the target server selects the hard disk from the readable and writable mobile storage device or the target server at the next startup. The disc starts the target server.

In summary, the present invention has the following advantages: First, in the hardware configuration, the control method of the server startup sequence of the present invention only needs to be readable and writable mobile storage devices, without requiring other hardware, thereby reducing the cost. Secondly, the control method of the present invention does not need to modify the hardware and operating system of the target server, thereby making the method highly secure; and third, the present invention is relative to various conventional methods. Control The method has the advantage of being simple and easy.

"FIG. 1A" is a block diagram of a system for executing a control method of a server startup sequence in the embodiment of the present invention. As shown, the system includes: a management server 10 and a target server 20.

The management server 10 includes a management program module 11 for issuing a startup command to the target server, and the startup command is used to select the target server 20 from the next startup. The hard disk boot is also initiated from the readable and writable mobile storage device 21.

Here, the readable and writable mobile storage device 21 includes a first proxy server module 211 for communicating with the management server 10. At the same time, the operating system 22 of the target server 20 includes a second proxy server module 221, which is similar to the first proxy server module 211. The second proxy server module 221 is also used with the management server 10. Communicate. The management server 10 can remotely control the target server 20 through the first proxy server module 211 and the second proxy server module 221, thereby achieving the purpose of controlling the startup sequence of the target server 20.

Next, the operation flow of the system shown in "1A" will be described in conjunction with "1B".

"1B" is a method for controlling the startup sequence of the server according to the embodiment of the present invention. The method flow chart is implemented by the management server to comprehensively control the startup sequence of the target server through the readable and writable mobile storage device, thereby improving the server management mode in the prior art.

First, a boot image is created and the first proxy server is placed in the boot image (step 101). Here, the boot image can be made according to the operating system of the target server, such as a Linux system or a Windows PE system, so that the target server can be started from the readable and writable mobile storage device containing the boot image in the subsequent steps. . The first proxy server program can be started along with the boot image and communicate with the management server, so that the management server can remotely control the target server through the first proxy server. Here, if it is necessary to complete some specific management work while starting the operating system of the target server, for example, if the system security management program needs to be called when the target server operating system is started, the corresponding management application can be And put it into this boot image.

Next, the boot image containing the first proxy server is restored on the readable and writable mobile storage device (step 102), so that the readable and writable mobile storage device can start the target server. At the same time, the management application pre-loaded in the boot image in step 101 can be copied to the readable and writable mobile storage device.

Here, the readable and writable mobile storage device for starting the target server is convenient to manufacture, and the readable and writable mobile storage device in the embodiment of the present invention can be used as an accessory component of the target server. Therefore, it is not necessary to make any changes to the original hardware in the target server during the control of the server startup sequence, thereby simplifying the server startup sequence. Control Method.

In addition, the readable and writable mobile storage device is any one of a rewritable optical disc, a rewritable digital video disc, and a USB flash device. For example, for a target server equipped with a CD burner, a rewritable digital video disc (DVD) can be selected as a readable and writable mobile storage device. In order to make the embodiment of the present invention have a wider application range, the readable and writable mobile storage device selected by the preferred embodiment of the present invention is a USB flash device. This is because the USB interface is the most basic configuration requirement for the server. Therefore, the USB flash device can further reduce the requirement of the server hardware configuration in the control method of the server startup sequence in the embodiment of the present invention.

Then, the second proxy server can be installed and operated in the hard disk booting operating system of the target server (step 103). The second proxy server is configured to communicate with the management server, so that the management server can remotely control the target server through the second proxy server.

The first proxy server program and the second proxy server program respectively perform a write operation on the readable and writable mobile storage device, so that in the subsequent step, the first proxy server program or the second proxy server program pair can be read and written. The write operation performed by the mobile storage device causes the readable and writable mobile storage device to lose or obtain the ability to start the target server, thereby achieving the purpose of controlling the server startup sequence.

In addition, the first proxy server and the second proxy server can also directly communicate with the management server, or input the IP address of the management server to the user. Then communicate with this management server.

After the first proxy server and the second proxy server communicate with the management server, the first proxy server or the second proxy server can perform certain management tasks according to the instructions of the management server, such as calling a certain Management application.

After the readable and writable mobile storage device is connected to the target server, the basic input and output system of the target server can be set (step 104).

Specifically, the boot sequence in the basic output input system (BIOS) of the target server must be set to: preferentially boot from the readable and writable mobile storage device. Therefore, the target server first selects to start from the readable and writable mobile storage device at each startup. The reason why the management server first selects to boot from the readable and writable mobile storage device at each startup is because the principle of the control method of the server startup sequence in the embodiment of the present invention is as follows: it must always be ensured that the target is included The readable and writable mobile storage device of the server boot image is the first boot device (or boot point) of the target server, and when the boot image included in the readable and writable mobile storage device cannot start the target server, the basic The input and output system can automatically find the next starting point to start the operating system, that is, start from the hard disk of the target server, thereby achieving the purpose of controlling the startup sequence of the target server.

Among them, because when the first starting point fails, the process of the basic input and output system sequentially searching for other starting points to start the operating system is a conventional technique, so it will not be described here.

Moreover, those skilled in the art should understand that when removing from the target server After the readable and writable mobile storage device, the target server can obtain active management rights from the centralized management of the management server.

Finally, the startup sequence of the target server at the next startup is determined according to the startup command issued by the management server (step 105).

The first proxy server or the second proxy server may modify the startup file in the readable and writable mobile storage device according to the instruction made in the startup instruction, so that the readable and writable mobile storage device is lost or activated. The capability of the target server, and then when the target server is next started, it is determined whether the target server will be booted from the readable and writable mobile storage device or from the hard disk of the target server, thereby finally achieving the startup of the control target server. The purpose of the order.

Hereinafter, the above-described step 105 will be described in detail in conjunction with "Fig. 2" and "Fig. 3".

FIG. 2 is a flowchart of a method for starting a target server from a hard disk of a target server in a method for controlling a server startup sequence according to an embodiment of the present invention.

As shown in "Fig. 2", the first proxy server receives a boot command indicating that the target server is booted from the hard disk of the target server (step 1051).

Then, the boot file in the readable and writable mobile storage device can be modified by the first proxy server program, so that the readable and writable mobile storage device loses the ability to start the target server (step 1053).

Wherein, the readable and writable boot file in the mobile storage device, for example: boot.int or grub configuration file, is used for booting when booting the operating system, so The boot.int or grub configuration file can be modified by the first proxy server program, so that the readable and writable mobile storage device loses the ability to start the target server operating system, and then the target server is started when the target server is started next time. The basic input and output system can sequentially find the next starting point (ie, the hard disk of the target server) to start the target server.

Next, the operating system of the target server can be started through the hard disk of the target server (step 1055).

After the target server is booted through the hard disk, the first proxy server or the second proxy server is also required to be started (step 1057), so that the target server is always in the management control of the management server, and thus can be implemented according to the actual situation. The startup sequence of the target server needs to be adjusted at any time.

Here, those skilled in the art should understand that when the readable and writable mobile storage device including the boot image is removed, the target server can be actively managed, in other words, when the readable and writable mobile storage is removed. When the device is in use, the target server can be booted directly from the hard drive.

FIG. 3 is a flowchart of a method for starting a target server from a readable and writable mobile storage device in a method for controlling a server startup sequence according to an embodiment of the present invention.

As shown in "Fig. 3", the second proxy server receives a boot command indicating that the target server is started from the readable and writable mobile storage device (step 1052).

Modifying the boot file in the readable and writable mobile storage device, for example: boot.int or grub configuration file, by using the second proxy server (step 1054), thereby Enables the readable and writable mobile storage device to acquire the ability to start the target server.

The target server can then be booted through the readable and writable mobile storage device (step 1056).

Through the above description, those skilled in the art can understand that the control method of the server startup sequence of the embodiment of the present invention has the following advantages as a brand new server management method: First, in the hardware configuration, the present invention The control method of the server startup sequence of the embodiment only needs to be readable and writable mobile storage device, and does not need other hardware, thereby reducing the cost. Secondly, the control method of the embodiment of the invention does not need to be hardware for the target server. The operating system makes changes, which in turn makes the method highly secure. Third, the control method of the embodiment of the present invention has the advantages of simplicity and ease of comparison with various conventional methods.

While the invention has been described above in the foregoing preferred embodiments, it is not intended to limit the invention. It will be appreciated by those skilled in the art that modifications and modifications are possible within the scope of the present invention without departing from the scope and spirit of the invention as disclosed in the appended claims.
