Description
Technical Field
The present invention relates to the field of computer and operating system technologies, and in particular, to an operating system installation control method, an installation control system, and a computing device.
Background
In automated testing of operating systems, it is necessary to install the latest system images built daily so that automated testing can be performed on the latest system daily.
The system can be updated conveniently and rapidly for a large number of testers through the PXE installation system mirror image, the latest daily system mirror image file is downloaded and deployed on the PXE server, and the testers can be restarted in a network starting mode to pull the mirror image file on the PXE server, so that the latest operating system is installed.
In the prior art, in the automated test of the AMD and ARM platforms, after a system is installed on a client through a PXE service, when the system needs to be updated next time, the client needs to be set to be started next time to be started by a network through an efiboost gr command, and then the client is restarted to enter the network to be started through a reboot command, so that the latest system image is installed on the client. Because in the AMD and ARM architecture clients, the BIOS uses the hard disk boot as the first boot sequence, the server needs to remotely log in to the client and modify the next boot of the client to be a network boot before installing the system image. After restarting the client, the client enters the PXE boot, installs a new operating system in a network-initiated manner. After the operating system is installed, the client is further guided to restart through the hard disk start, and then the post-installation configuration is entered, so that the installation of the operating system is completed.
Therefore, in the automatic deployment process of installing the daily-built operating system on the AMD and ARM platforms, a plurality of operations need to be restarted on the client, after the operating system is installed, the operations need to be restarted to enter the post-installation configuration, the secondary installation of the client and the like are also needed, and the installation process is complicated. Moreover, the next restart item of the client needs to be selected by using the efiboost command, if the efiboost command is not available on the MIPS platform, when the system is installed through the PXE service, the BIOS setting can only be manually entered through the restart, the startup item is modified to be network-started, and then the network installation system can be entered through the PXE service after restarting again. Thus, the latest mirror image cannot be automatically and unattended installed.
For this reason, an operating system installation control method is required to solve the problems in the above-described technical solutions.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
FIG. 1 shows a schematic diagram of an installation control system 100 according to one embodiment of the invention.
As shown in fig. 1, the installation control system 100 includes a server 120, one or more clients 110 connected to the server 120.
The server 120 is used to control the client to install a new operating system. The invention is not limited to the specific implementation of the server. For example, server 120 may be implemented as a computing device such as a desktop computer, a notebook computer, a processor chip, a cell phone, a tablet computer, etc., but is not limited thereto, and may be an application program residing on the computing device.
The client 110 may be a testing machine that, after controlling the client 110 to install a new operating system, may test the new operating system installed by the client. It should be noted that the invention is not limited to the particular type of equipment of the tester. For example, the test machine may be implemented as a computing device such as a desktop computer, a notebook computer, a cell phone, a tablet computer, and the like.
According to one embodiment of the invention, the server 120 may be implemented as a PXE server and the client may be implemented as a PXE client. The PXE server may establish a remote connection with the PXE client via SSH protocol.
The server 120 has a TFTP service program resident therein, and the TFTP service program may perform data interaction with the client 110 based on a UDP protocol, so that the client 110 performs data interaction with the server 120 based on the UDP protocol.
In one embodiment, the boot sequence is configured in advance at the BIOS boot item of the client 110, the first boot item is set to be a network boot operating system, and the second boot item is set to be a hard disk boot operating system.
The server 120 may continuously transmit a multicast signal (Discover signal) based on the UDP protocol. After restarting, the client 110 to install the new operating system may receive the multicast signal of the server 120, and automatically enter the network start mode of the first start item after receiving the multicast signal of the server 120, and start the operating system through the network.
It should be noted that by network booting the operating system, client 110 may be directed to install and enter a new operating system.
Since the client performs data interaction with the server based on the UDP protocol, the client 110 can transmit data to the server 120 and receive data transmitted from the server 120 based on the UDP protocol. Based on this, only when the UDP data transmission of the client is started, the client may receive the multicast signal transmitted by the server, enter the network start mode, and may then return an acquisition request for the boot file to the server based on the UDP protocol. After detecting the request for obtaining the boot file from the client 110, the server 120 sends the boot file to the client, and executes the boot file on the client to boot the client to install the latest operating system.
In addition, by closing the data transmission of the client 110 based on the UDP protocol, after restarting the client 110, the client may enter a hard disk start mode of the second start item, and start the operating system through the hard disk, so that the client enters the currently installed operating system.
In one embodiment, the server 120 is adapted to perform an operating system installation control method 300 according to the present invention. The operating system installation control method 300 of the present invention will be described in detail below.
In one embodiment, the server 120 may be implemented as a computing device 200 such that the operating system installation control method 300 of the present invention may be executed in the computing device 200.
FIG. 2 shows a schematic diagram of a computing device 200 according to one embodiment of the invention.
As shown in FIG. 2, in a basic configuration 202, computing device 200 typically includes a system memory 206 and one or more processors 204. A memory bus 208 may be used for communication between the processor 204 and the system memory 206.
Depending on the desired configuration, the processor 204 may be any type of processing including, but not limited to: a microprocessor (UP), a microcontroller (UC), a digital information processor (DSP), or any combination thereof. Processor 204 may include one or more levels of cache, such as a first level cache 210 and a second level cache 212, a processor core 214, and registers 216. The example processor core 214 may include an Arithmetic Logic Unit (ALU), a Floating Point Unit (FPU), a digital signal processing core (DSP core), or any combination thereof. The example memory controller 218 may be used with the processor 204, or in some implementations, the memory controller 218 may be an internal part of the processor 204.
Depending on the desired configuration, system memory 206 may be any type of memory including, but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. The system memory 206 may include an operating system 220, one or more applications 222, and program data 224. The application 222 is in effect a plurality of program instructions for instructing the processor 204 to perform a corresponding operation. In some implementations, the application 222 can be arranged to cause the processor 204 to operate with the program data 224 on an operating system.
Computing device 200 also includes storage device 232, storage device 232 including removable storage 236 and non-removable storage 238.
Computing device 200 may also include a storage interface bus 234. Storage interface bus 234 enables communication from storage devices 232 (e.g., removable storage 236 and non-removable storage 238) to base configuration 202 via bus/interface controller 230. At least a portion of the operating system 220, applications 222, and data 224 may be stored on removable storage 236 and/or non-removable storage 238 and loaded into the system memory 206 via the storage interface bus 234 and executed by the one or more processors 204 when the computing device 200 is powered up or the application 222 is to be executed.
Computing device 200 may also include an interface bus 240 that facilitates communication from various interface devices (e.g., output devices 242, peripheral interfaces 244, and communication devices 246) to basic configuration 202 via bus/interface controller 230. The example output device 242 includes a graphics processing unit 248 and an audio processing unit 250.

The example communication device 246 may include a network controller 260 that may be arranged to facilitate communication with one or more other computing devices 262 over a network communication link via one or more communication ports 264.
The network communication link may be one example of a communication medium. Communication media may typically be embodied by computer readable instructions, data structures, program modules, and may include any information delivery media in a modulated data signal, such as a carrier wave or other transport mechanism. A "modulated data signal" may be a signal that has one or more of its data set or changed in such a manner as to encode information in the signal. By way of non-limiting example, communication media may include wired media such as a wired network or special purpose network, and wireless media such as acoustic, radio Frequency (RF), microwave, infrared (IR) or other wireless media. The term computer readable media as used herein may include both storage media and communication media.
In an embodiment in accordance with the present invention, computing device 200 is configured to execute an operating system installation control method 300 in accordance with the present invention. The application of the computing device 200 includes a plurality of program instructions for executing the operating system installation control method 300 of the present invention, where the program instructions may instruct the processor to execute the operating system installation control method 300 of the present invention, so that the computing device 200 precisely controls and directs the client to install a new operating system by executing the operating system installation control method 300 of the present invention.
FIG. 3 illustrates a flow chart of an operating system installation control method 300 according to one embodiment of the invention. The operating system installation control method 300 may be executed in a server (e.g., the aforementioned computing device 200).
In an embodiment of the present invention, server 120 may establish a remote connection with one or more clients 110 to communicate with clients 110 and control clients 110 to install a new operating system.
According to one embodiment of the invention, the invention is not limited to a particular type of operating system installed at the client. For example, the operating system may be a Linux operating system, a UOS operating system, a Windows operating system, or the like.
As shown in fig. 3, the operating system installation control method 300 starts at step S310.
In step S310, the operating system of the client 110 is started up through the network.
Here, before step S310 is performed, the boot sequence may be configured at the BIOS boot item of the client 110, the first boot item is set to be a network boot operating system, and the second boot item is set to be a hard disk boot operating system.
In one embodiment, before the operating system of the client is started through the network, the client will restart, then the client detects whether the multicast signal sent by the server is received, and if the multicast signal sent by the server is received, the operating system is determined to be started through the network, and the network starting mode is entered.
If the multicast signal sent by the server is not received, the operating system is started through the hard disk, and the client can enter the currently installed operating system through the hard disk.
It should be noted that, the client 110 and the server 120 may perform data interaction based on the UDP protocol. The server 120 may continuously transmit a multicast signal (Discover signal) based on the UDP protocol, so that the client 110 to which a new operating system is to be installed may receive the multicast signal of the server 120 and automatically enter the network start mode of the first start-up item after receiving the multicast signal of the server 120, and start the operating system through the network.
It should be noted that by network booting the operating system, client 110 may be directed to install and enter a new operating system. See in particular the following description of the steps.
In step S320, it is circularly detected whether the client has transmitted an acquisition request for the boot file.
Subsequently, in step S330, if an acquisition request of the client for the boot file is detected, the boot file is transmitted to the client so as to boot the client to install a new operating system based on the boot file.
In one embodiment, the client downloads the boot file based on the address of the boot file by sending the address of the boot file to the client.
As described above, the client performs data interaction with the server based on the UDP protocol, so that the client 110 can transmit data to the server 120 and receive data transmitted by the server 120 based on the UDP protocol. Based on the above, only when the client side starts the UDP data transmission, the client side can receive the multicast signal transmitted by the server, enter the network starting mode, and return the acquisition request for the guide file to the server based on the UDP protocol, and the server can receive the acquisition request for the guide file transmitted by the client side based on the UDP protocol. After detecting the acquisition request of the boot file sent by the client, sending the boot file to the client, and guiding the client to install the latest operating system by executing the boot file on the client.
Finally, in step S340, the data transmission of the client is turned off. Specifically, after detecting the acquisition request of the client to the boot file, the client is also closed to send data to the server based on the UDP protocol. Therefore, after restarting the client again, the client enters the hard disk starting mode of the second starting item, and the operating system is started through the hard disk, so that the client enters the new installed operating system.
It should be noted that, after the client finishes installing a new operating system, the client will be restarted automatically. Here, since the UDP data transmission of the client has been turned off, after the client is restarted, the multicast signal transmitted by the server is not received, and the request for acquiring the boot file is not transmitted to the server, and the server cannot receive the data transmitted by the client based on the UDP protocol, so that the request for acquiring the boot file transmitted by the client is not received, and the boot file is not transmitted to the client to boot the client to install a new operating system through the network.
After the client finishes installing a new operating system and restarting, if the multicast signal sent by the server is not received after waiting for a preset time, the client enters a hard disk starting mode, and the operating system is started through the hard disk, so that the client can normally enter the new operating system.
It should be understood that before the UDP data of the client is not started, the client starts the operating system through the hard disk after each restart, and normally enters the currently installed operating system.
When the latest operating system is required to be reinstalled, the client side needs to start UDP data transmission, so that after the client side is restarted, the client side can perform data interaction with the server based on UDP protocol, can receive a multicast signal transmitted by the server, enter a mode of starting the operating system through a network, and can transmit an acquisition request for the guide file to the server, and the server can receive the acquisition request for the guide file transmitted by the client side. After detecting the client's request for the boot file, the server 120 directs the client to install the latest operating system by sending the boot file to the client.
In one implementation, the server 120 masks the UDP data transmission corresponding to the IP by determining the IP of the client, so as to implement closing the client to transmit data based on the UDP protocol, and masking the client. Specifically, firewall rules may be added by the following commands, closing the client UDP based data transmission:
sudo iptables-A OUTPUT-d IP-p udp-j REJECT。
according to one embodiment of the invention, after the client enters a new operating system, automated testing of the new operating system may be performed. Specifically, when the latest operating system needs to be tested, the client can receive the multicast signal sent by the server after restarting by starting the UDP data transmission of the client, enter the network to start the operating system, and can realize the installation of the latest operating system on the client by executing the steps S320 to S340. After the latest operating system is installed and restarted again, the client can enter the latest operating system, and then the latest operating system can be tested.
In one implementation, firewall rules may be deleted by the following commands, turning on client UDP-based data transmission:
sudo iptables-F。
according to one embodiment, the server may be implemented as a PXE server and the client may be implemented as a PXE client. Before performing the method 300 according to the present invention, the PXE server may establish a remote connection with the PXE client via the SSH protocol.
A TFTP service program may be installed in the server 120, and may perform data interaction with the client 110 based on a UDP protocol, so that the client 110 performs data interaction with the server 120 based on the UDP protocol. The TFTP service program may receive a request for obtaining a boot file sent by the remote client, and return the boot file to the remote client.
The server 120 may cycle through detecting client acquisition requests for boot files by: and circularly detecting whether the tftp sending log of the client exists in the var/log/daemon.log file. If so, it is determined that the client completes the UDP data transmission (request for acquiring the boot file transmitted based on the UDP protocol), so that it can be determined that the acquisition request for the boot file transmitted by the client is detected.
In one implementation, the client executes the received boot file after receiving the boot file. Then, the client requests to obtain the configuration file for the local from the TFTP server program in the server 120, and the TFTP server program returns the configuration file to the client, so that the client can perform subsequent operations according to the configuration file. Specifically, the client sends an acquisition request for the kernel file to the TFTP server, and the TFTP sends the kernel file to the client after receiving the acquisition request. The client then sends an acquisition request for the root file to the TFTP server, which returns the root file system to the client. Then, the client starts the kernel, downloads the installation source file, reads the automatic installation script and realizes automatic installation of a new operating system.
According to the operating system installation control method 300, the server controls the client UDP data transmission to be started and closed, so that the client can receive the multicast signal of the server in the state of starting the data transmission, automatically enter a network starting mode, and realize that the network guides the client to install a new operating system. After the new operating system is installed, the client cannot receive the multicast signal of the server after restarting by closing the UDP data transmission of the client, so that the client automatically enters a hard disk starting mode, and the new operating system can be entered through hard disk starting. Therefore, the server can accurately control a plurality of clients to install a new operating system or enter the operating system by controlling the starting mode of the clients, and also realize that the clients automatically install the new operating system under the unattended condition and automatically restart to enter the new operating system so as to test the new operating system.
The method of any one of A1-A7, wherein the client is adapted to interact data with the server based on UDP protocol.
A9, the method of any one of A1-A8, wherein the server is a PXE server, and the client is a PXE client; the server is remotely connected with the client.
