It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
Before describing the method provided by the present disclosure, the following process of mounting an ISO image file on a KVM is described: the KVM receives a user instruction, and the user instruction indicates the ISO image files needing mounting and specified by the user on the user interface. The KVM opens this ISO image according to the user instruction. This means that the ISO image has been successfully mounted.
After the KVM has successfully mounted the ISO image file, the BMC virtualizes a CD/DVD device based on USB. The CD/DVD device stores the ISO image described above. Since the CD/DVD device is USB based, at this point, the server and BMC may assume that there is a USB channel interaction.
The OS installation of the server is divided into: kernel-mode installation and user-mode installation. The present disclosure relates generally to user-mode installation. When the user mode is installed, the server needs to access the CD/DVD device so as to obtain a source file of the ISO image file according to the ISO image file for installation. An ISO image file is not identical to its source file. As an example, an ISO image may include only a few file directories, and not specifically file contents. When the server performs user mode installation, specific file content (namely, a source file) is acquired according to a file directory in the ISO image file. How a server acquires a source file of an ISO image file is described below with fig. 1.
As shown in fig. 1, the process may include:
step 101, the server sends a file instruction to the BMC through the USB channel.
At step 102, the BMC sends the request to the KVM via the LAN channel with the KVM.
In step 103, the KVM sends the source file to the BMC through the LAN channel between the KVM and the BMC.
And step 104, the BMC sends the source file to the server through a USB channel between the source file and the server.
As can be seen from the above steps 101 to 104, when the server executes user mode installation, a source file required by the server is transferred in the BMC, and the BMC performs conversion from the LAN to the USB on the source file, which reduces the speed of acquiring the source file by the server, and further reduces the OS installation efficiency of the server.
To avoid the above problem, the present disclosure provides an OS installation method. In the method provided by the present disclosure, the BMC controls the KVM to add a specific file to the ISO image file, where the specific file is used to install a user-mode program, which may be, for example, a kickstart file in a specific implementation. The appointed file comprises network parameters of a source file used for obtaining an ISO (International organization for standardization) image file, and based on the network parameters, when a user mode is installed, the server can directly obtain the source file through an LAN (local area network) channel to install the OS.
The method provided by the present disclosure is described below by means of fig. 2:
referring to fig. 2, fig. 2 is a flow chart of a method provided by the present disclosure. This flow applies to the BMC, where the BMC is used to monitor and manage the server.
As shown in fig. 2, the process may include the following steps:
in step 201, when monitoring that the server is started from the ISO image file, the BMC sends an analysis notification to the KVM, where the analysis notification is used to instruct the KVM to analyze the ISO image file.
In the embodiment of the present disclosure, the ISO image file may be an ISO image file mounted by the KVM described above.
In the embodiment of the present disclosure, after the KVM mounts the ISO image file, the server is powered on and enters a BIOS (Basic Input Output System). The BIOS is a set of programs that is fixed to a ROM chip on a server motherboard, and stores the most important basic input/output programs of the server, system setting information, a post-boot self-test program, and a system self-boot program. Its primary function is to provide the lowest level, most direct hardware setup and control for the computer.
After the server is started and enters the BIOS, the CD/DVD equipment virtualized from the BMC is started. Here, the server is started from a BMC virtual CD/DVD device, meaning that the server is started from an ISO image stored on the CD/DVD device. Because the CD/DVD device is BMC virtualized, the BMC will monitor in time once the server boots from the BMC virtualized CD/DVD device (the server boots from the ISO image file). Once the BMC monitors that the server is started from the ISO image, a resolution notification is sent to the KVM.
And when the KVM receives the analysis notice sent by the BMC, the ISO mirror image file is analyzed according to the analysis notice. And sending a request message to the BMC if the specified file does not exist in the analyzed ISO mirror image file. The specified file is used for installing the user mode program, and a specific implementation of the specified file can be a kickstart file.
After the KVM sends the request message to the BMC, step 202 is performed.
Step 202, the BMC receives a request message sent by the KVM, where the request message is sent when the KVM is analyzed that the ISO image file does not have a designated file, and the designated file is used for installing a user mode program.
Step 203, the BMC controls the KVM to add an assigned file to the ISO image file according to the request message, where the assigned file includes a network parameter for acquiring a source file of the ISO image file, so that the server acquires the source file through the LAN channel based on the network parameter in the assigned file to perform OS installation.
In one example, the BMC controlling the KVM to add the specified file to the ISO image may include: and the BMC searches the specified file matched with the ISO mirror image file locally and sends the searched specified file to the KVM. And after receiving the specified file, the KVM adds the specified file to the ISO mirror image file. Finally, the BMC controls the KVM to add the designated file to the ISO mirror image file.
In the flow shown in fig. 2, as an embodiment, the specific implementation of the network parameter may include: specifying an IP address, specifying a port.
The specified IP address and the IP address of the user side equipment where the KVM is located are in the same network segment. As an embodiment, the specified IP address may be an IP address of the user-side device where the KVM is located.
And designating the port as a port on the user side equipment, wherein the port is a cut-off idle port which is not occupied by other services currently.
Taking network parameters as an appointed IP address, an appointed port and a service type as examples, once the appointed IP address and the appointed port are added in an appointed file, the server takes the appointed IP address as a destination IP address and the appointed port as a destination port, and directly accesses the destination IP address and the destination port through a LAN channel to acquire a source file for OS installation. Compared with the existing mode of transferring and acquiring the source file through the BMC, the method greatly improves the installation efficiency of the server OS.
It should be noted that, as an embodiment, the network parameters may further include: such as ftp service or http service. Thereafter, the KVM may initiate a service corresponding to the service type, such as ftp or http, at the designated port. Further, when the server accesses the destination IP address as the designated IP address and the destination port as the designated port through the LAN channel, the server also accesses the destination IP address according to a protocol corresponding to the service type (for example, ftp corresponding to ftp service).
Thus, the flow shown in fig. 2 is completed.
As can be seen from the flow shown in fig. 2, the BMC controls the KVM to add a specific file (for installing the user mode program) to the ISO image file, where the specific file includes the network parameter of the source file for obtaining the ISO image file. In this way, when installing a user mode program (part of the OS), the server acquires a source file through the LAN channel based on the network parameter to install the OS. Compared with the existing mode of acquiring the source file by transferring the BMC, the mode of directly acquiring the source file through the LAN channel based on the network parameters greatly improves the installation efficiency of the server OS.
In particular implementations, the server is OS-installed according to a configuration file in the ISO image file. The configuration file can be a grub2.conf file in an ISO image file. Based on this, as an embodiment, in the flow shown in fig. 2, the method may further include: and controlling the KVM to add the path parameter of the specified file in the configuration file of the ISO image file so that the server reads the path parameter when the OS is installed according to the configuration file and accesses the specified file according to the path parameter. In one example, controlling the KVM to add a path parameter of a specified file in a configuration file of the ISO image file may include: and the BMC determines the position of the specified file in the ISO mirror image file, determines a path parameter according to the position and sends the path parameter to the KVM. And after receiving the path parameters, the KVM adds the path parameters to the configuration file. Finally, the BMC controls the KVM to add the path parameter of the designated file in the configuration file of the ISO mirror image file.
As described above, as an embodiment, the path parameters herein include at least: specifying a location of a file in the ISO image file.
Thus, when the server installs the OS according to the configuration file, the server reads the specified file in the ISO image file according to the path parameter of the specified file in the configuration file, and then acquires the source file through the LAN channel according to the network parameter in the specified file to install the OS.
It should be noted that, as described above, the KVM starts a service corresponding to the service type, such as ftp or http, at the specified port. However, the designated port is not always continuously enabled, and as an embodiment, when the BMC monitors that the server is automatically restarted after the OS is installed, the BMC notifies the KVM to disable the designated port, so as to prevent unnecessary installation trouble.
The OS installation method provided by the present disclosure is described above in terms of standing at BMC and by the flow shown in fig. 2. The following stations describe the OS installation method provided by the present disclosure in a KVM perspective:
referring to fig. 3, fig. 3 is a flowchart of another OS installation method provided by the present disclosure. The method is applied to KVM.
As shown in fig. 3, the process may include the following steps:
step 301, the KVM receives an analysis notification sent by the BMC, where the analysis notification is sent by the BMC when monitoring that the server is started from the ISO image file, and is used to instruct to analyze the ISO image file.
This step 301 corresponds to the above step 201.
Step 302, the KVM analyzes the ISO image file according to the analysis notification, and if no specified file exists in the analyzed ISO image file, the BMC sends a request message to the BMC, so that the BMC controls the KVM to add the specified file to the ISO image file according to the request message.
This step 302 corresponds to the step 202, and the specified file is described above, which is not described herein again.
As an embodiment, in step 302, the KVM parsing the ISO image file may include:
step a1, judging whether the ISO mirror image file meets the specified format, if so, executing step a 2.
In step a1, the specified format may be: the format required by the Linux ISO mirror system can be started.
For one embodiment, in step a1, when the ISO image is determined not to satisfy the specified format, the current process may be ended.
Step a2, judging whether the ISO mirror image file has a designated file, if so, determining that the designated file exists in the ISO mirror image file, otherwise, determining that the designated file does not exist in the ISO mirror image file.
Through the steps a1 and a2, the KVM can analyze the ISO image.
Step 303, the KVM adds a specific file to the ISO image file according to the control of the BMC, where the specific file includes a network parameter for obtaining a source file of the ISO image file, so that the server obtains the source file through the LAN channel based on the network parameter in the specific file to perform OS installation.
This step 303 corresponds to the step 203 described above, and is not described herein again.
The network parameters are as described above and will not be described in detail here.
The flow shown in fig. 3 is completed.
In order to facilitate the server to read the specified file when performing OS installation according to the configuration file, the flow shown in fig. 3 may further include: and the KVM adds the path parameter of the specified file to the configuration file of the ISO mirror image file according to the control of the BMC so that the server accesses the specified file according to the path parameter. The path parameters include at least: the location of the specified file in the ISO image file.
As an embodiment, the adding, by the KVM under the control of the BMC, the path parameter of the specified file to the configuration file of the ISO image file may include: the KVM sends a path parameter request to the BMC, receives a path parameter returned by the BMC, and determines the path parameter according to the position of the specified file in the ISO image file by the BMC as described above; when the KVM receives the path parameter, the path parameter is added to the configuration file of the ISO image file. Finally, the KVM is controlled according to the BMC, and the path parameter of the designated file is added to the configuration file of the ISO mirror image file.
The process flow shown in FIG. 3 is described from a KVM perspective. It should be noted that, as described above, the network parameters may further include: such as ftp service or http service. Thereafter, the KVM may initiate a service corresponding to the service type, such as ftp or http, at the designated port. However, the designated port is not always on, and as an embodiment, the KVM may close the designated port when receiving a close notification from the BMC, so as to prevent unnecessary installation trouble. The shutdown notification is sent by the BMC upon monitoring that the server has completed OS installation and is automatically restarted.
For the convenience of understanding, the disclosure is described by way of example through an embodiment in conjunction with the flow shown in fig. 2 and 3:
referring to fig. 4, fig. 4 is a diagram of a network scene structure applied in the present disclosure. As shown in fig. 4, the KVM runs on the user side device (PC) 20. BMC22 has a first port 221 and a second port 222. The first port 221 is connected to the server 23 through a USB channel. The second Port 222 is connected to the server's Port1, for example, through an NCSI link. Port1 may be, for example, a network Port. The server 23 is installed with a BIOS. Port1 of server 23 is connected to PC20 through a LAN channel.
Based on the structure shown in fig. 4, the following describes the OS installation of the server by way of example:
before describing OS installation, preparation before OS installation is described:
after the KVM mounts the ISO image file to the server, the server 23 boots into BIOS and boots the CD/DVD device virtualized from BMC 22.
When monitoring that the server 23 is started from the ISO image file, the BMC22 sends a resolution notification to the KVM, where the resolution notification is used to instruct the KVM to resolve the ISO image file.
The KVM receives the resolution notification sent by the BMC 22. Then, the KVM parses the ISO image according to the parsing notification, and sends a request message to the BMC22 if it is parsed that there is no specific file (here, a Kickstart file is taken as an example) in the ISO image.
The BMC22 receives the request message sent by the KVM. And then, according to the request message, locally searching a Kickstart file matched with the ISO mirror image file, and sending the searched Kickstart file to the KVM.
And after receiving the Kickstart file, the KVM adds the Kickstart file to the ISO mirror image file. The Kickstart file is configured with a designated IP address, a designated port and a service type. Wherein the designated IP address is in the same network segment as the IP address of the PC20 (for example, the IP address of the PC 20). The port is designated as the free one on PC 20. The KVM may initiate a specified service such as ftp or http, etc. at a specified port on PC 20. The KVM also opens ftp service according to the service type (exemplified by ftp service).
So far, the Kickstart file is stored in the ISO image file.
In this embodiment, the BMC22 may further send the path parameter of the Kickstart file to the KVM.
After receiving the path parameter, the KVM adds the path parameter to the configuration file of the ISO image file (here, grub2.conf is taken as an example). To this end, grub2.conf of the ISO image file stores the path parameters of the Kickstart file.
As described above, the Kickstart file is stored in the ISO image file, and the grub2.conf of the ISO image file stores the path parameter of the Kickstart file.
The following describes OS installation of the server 23:
the OS installation of the server 23 includes kernel-state installation and user-state installation. Wherein, the kernel-mode installation of the server 23 is similar to the existing kernel-mode installation process. This embodiment focuses on user-mode installation:
after the kernel-state installation of the server 23 is completed, the server 23 finds the path parameter of the Kickstart file according to the grub2.conf file, and then accesses the Kickstart file according to the path parameter of the Kickstart file.
The server 23 accesses and reads a Kickstart file, where a designated IP address, a designated port, and a service type are configured in the Kickstart file, and then the server 23 downloads a source file through a LAN channel of the PC20 according to a protocol corresponding to the service type, such as an ftp protocol, with the designated IP address as a destination IP address and the designated port as a destination port, where fig. 5 shows an illustration of user mode installation. Compared with the method for forwarding and reading the source file through the BMC in the user mode installation shown in fig. 1, the method for directly downloading the source file through the LAN channel of the PC20 by the server 23 according to the embodiment of the present disclosure may greatly improve the speed of the user mode installation.
The server 23 performs installation according to the downloaded source file.
After the server 23 completes the OS installation, the server 23 is automatically restarted.
When the BMC22 monitors the server 23 to automatically restart, it notifies the KVM to close the opened designated port.
And the KVM receives the notification, and closes the opened appointed port.
The description of the embodiment shown in fig. 4 is thus completed.
The method provided by the present disclosure is described above, and the apparatus provided by the present disclosure is described below:
referring to fig. 6, fig. 6 is a block diagram of an apparatus provided in the present disclosure. The apparatus is applied to BMC, and corresponds to the flow shown in fig. 2. The BMC here is used to monitor and manage the server.
As shown in fig. 6, the apparatus includes:
the monitoring unit is used for monitoring that when the server is started from the mounted ISO mirror image file, an analysis notice is sent to the KVM, and the analysis notice is used for indicating the KVM to analyze the ISO mirror image file;
a message unit, configured to receive a request message sent by the KVM, where the request message is sent when the specified file does not exist in the ISO image file analyzed by the KVM;
and the control unit is used for controlling the KVM to add the specified file to the ISO image file according to the request message, wherein the specified file comprises network parameters used for acquiring a source file of the ISO image file, so that the server acquires the source file through a LAN (local area network) channel based on the network parameters in the specified file to install the OS.
As one embodiment, the network parameters include: appointing an IP address and an appointed port;
