Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present application discloses an installation configuration method of a physical machine, which is applied to a configuration center platform, and the installation configuration method of the physical machine includes:

s101, acquiring identification information of a physical machine to be installed and identification information of a target operating system, which are input by a user.

Wherein, the identification information of the physical machine to be installed comprises: a target host name and a target Internet Protocol (IP) address of the physical machine to be installed.

The physical machine to be installed is a physical machine needing to install the configuration system, the target host name of the physical machine to be installed is the host name of the physical machine to be installed after installation configuration is completed, which is set by a user, and the target IP address is the IP address of the physical machine to be installed after installation configuration is completed, which is set by the user. The target operating system is the operating system that the physical machine to be installed needs to install.

The identification information of the physical machine to be installed can be uploaded to the configuration center platform in an electronic form file form, or can be a filling interface for displaying the identification information of the physical machine to be installed on a front-end interface by the configuration center platform, then a user inputs the identification information of the physical machine to be installed on the filling interface, and the identification information of the physical machine to be installed is input into the configuration center platform through the filling interface.

Optionally, the identification information of the physical machine to be installed may further include information such as a mask and a gateway of the physical machine to be installed, including but not limited to what is proposed in the embodiments of the present application.

Alternatively, the identification information of the target operating system may be a name, version number, or the like of the target operating system.

Optionally, before performing step S101, login verification of the user through the configuration center platform may be further included, so that the user logs in the configuration center platform. After the user successfully logs in the configuration center platform, step S101 is executed.

Alternatively, the identification information of the physical machine to be installed and the identification information of the target operating system of the physical machine to be installed may not be acquired at the same time. For example, after the user inputs the identification information of the physical machine to be installed to the configuration center platform, the configuration center platform performs operations such as parsing and verification on the acquired identification information of the physical machine to be installed, so that the user can ensure that the identification information uploaded by the user is indeed the identification information of the physical machine that the user needs to install, and then the user inputs the identification information of the target operating system to enter the subsequent installation configuration.

It should be noted that the configuration center platform for executing the embodiment shown in fig. 1 may be composed of one server, that is, one server executes the embodiment shown in fig. 1, or may be composed of a plurality of servers, that is, the embodiment shown in fig. 1 may be executed by cooperation of a plurality of servers. Different functional modules may be deployed in different servers and cooperate to perform the process illustrated in fig. 1.

And S102, determining installation information of the physical machine to be installed by using the identification information of the physical machine to be installed.

Wherein, treat the installation information of installation physics machine, include: the service type of the physical machine to be installed and Intelligent Platform Management Interface (IPMI) information of the physical machine to be installed. The installation information of the physical machine to be installed is information that needs to be used when the physical machine to be installed is installed and configured.

The service class of the physical machine to be installed is used for explaining the service class for which the physical machine to be installed is responsible. In an actual application scenario, when a large amount of physical machine installation configuration operations are executed, since the services responsible for different physical machines are different, for example, an airline company is taken as an example, part of the physical machines are used for an on-duty service, and part of the physical machines are used for the international terminal service … …, the service types responsible for the physical machines to be installed can be known through installation information of the physical machines to be installed, and then customized installation can be performed for the services responsible for the physical machines to be installed. And the IPMI information of the physical machine to be installed is used for configuring the central platform to remotely log in and operate the physical machine to be installed. When the physical machine to be installed is installed, the physical machine to be installed needs to be logged in and controlled to perform operation of installing and configuring the system, so that the IPMI information required when the physical machine to be installed is remotely logged in needs to be used.

Specifically, the step S102 is executed by associating and storing the identification information of the physical machine to be installed and the installation information in advance, and then, after the user needs to perform the installation of the physical machine to be installed, only the identification information of the physical machine to be installed needs to be input to the configuration center platform, and when the step S102 is executed, the associated installation information can be called out through the identification information.

Optionally, in a specific embodiment of the present application, the installation information may further include: and a remote boot Environment (PXE) server corresponding to the physical machine to be installed. If the PXE server is used to execute the system installation operation, the installation information needs to include the PXE server corresponding to the physical machine to be installed.

Optionally, referring to fig. 2, in an embodiment of the present application, an implementation of step S102 is performed, including:

s201, calling a Configuration Management Database (CMDB) in the Configuration center platform to analyze the identification information of the physical machine to be installed, and analyzing to obtain installation information to be verified of the physical machine to be installed.

Specifically, the configuration center platform is provided with a CMDB module, and the identification information and the installation information of all the physical machines to be installed are input to the CMDB module in advance, so that the identification information is analyzed by calling the CMDB module when step S201 is executed, that is, the installation information to be verified of the physical machines to be installed can be obtained through analysis. The installation information to be verified refers to installation information which is obtained by analyzing the identification information through the CMDB and is not verified by a user.

S202, displaying installation information to be verified of the physical machine to be installed.

And outputting the installation information to be verified of the physical machine to be installed to a display interface of the configuration center platform, and confirming and verifying by a user. In some cases, the identification information that the user may input is incorrect, or the installation information entered into the CMDB is incorrect, so that the installation information to be verified obtained in step S201 is not the installation information of the physical machine to be installed that the user needs to install, and if the installation information is incorrect, the configuration cannot be successfully installed, or another physical machine is installed. Therefore, installation information to be verified of the physical machine to be installed needs to be displayed on an interface of the configuration center platform for a user to verify.

S203, responding to the confirmation operation of the user on the installation information to be verified, and determining the installation information to be verified of the physical machine to be installed as the installation information of the physical machine to be installed.

If the user confirms that the installation information to be verified is the installation information of the physical machine to be installed, the confirmation operation of the installation information to be verified is executed on the configuration center platform, the configuration center platform responds to the confirmation operation of the user on the installation information to be verified, the installation information to be verified of the physical machine to be installed is determined as the installation information of the physical machine to be installed, and the installation information is continuously used for executing subsequent processes.

For example, the configuration center platform may output an interface for confirming whether the installation information to be verified is the installation information of the physical machine to be installed, after the user clicks the confirmation, the configuration center platform directly determines the installation information to be verified as the installation information of the physical machine to be installed, and then performs the subsequent steps.

Optionally, in a specific embodiment of the present application, after the step S203 is executed, that is, after it is confirmed that the installation information to be verified is installation information of the physical machine to be installed, the user inputs identification information of the target operating system to the configuration center platform, and starts to execute the installation and configuration operations in the subsequent steps S103 to S106.

Optionally, if the user responds to the operation of denying the installation information to be verified, the installation information to be verified is not determined as the installation information of the physical machine to be installed, and the process is ended.

S103, logging in the physical machine to be installed through IPMI information, and acquiring a Media Access Control (MAC) address of the physical machine to be installed from the physical machine to be installed.

Because the installation information of the physical machine to be installed comprises the IPMI information of the physical machine to be installed, the physical machine to be installed can be remotely logged in through the IPMI information, and further, the MAC address of the physical machine to be installed can be acquired from the physical machine to be installed in a mode of inquiring the port of the physical machine to be installed, and the MAC address can also be considered as the MAC address of the network card of the physical machine to be installed. Optionally, in addition to the MAC address, the disk information of the physical machine to be installed may be acquired, and a disk array (raid) may be performed on the system disk after the physical machine to be installed is installed through the disk information of the physical machine to be installed.

For example, as shown in fig. 3, MAC address information and disk information of the physical machine to be installed are displayed on the interface of the configuration center platform. Wherein the MAC address information includes: switches (switch), ports (port), and virtual local area networks (vlan). The disk information includes: disk number (enclosureid), size (size), slot (slot), and disk array (is-raid).

Optionally, in a specific embodiment of the present application, if the MAC address information of the physical machine to be installed indicates that the physical machine to be installed has multiple network cards, the multiple network cards may be subjected to link aggregation when the physical machine to be installed is installed, so as to ensure stable execution of the installation work.

Alternatively, referring to fig. 4, if the installation information of the physical machine to be installed further includes: if the information of the PXE server corresponding to the physical machine to be installed is obtained, an implementation manner of step S103 is executed, and includes:

s401, responding to the port query task creating operation of a user, and logging in a physical machine to be installed through IPMI information.

The configuration center platform inquires a task creation interface to the user output port, various physical machines capable of creating the port inquiry tasks are displayed on the port inquiry task creation interface, and the user can create the port inquiry tasks of the physical machines to be installed by selecting the physical machines to be installed. And the port query task is used for acquiring the MAC address so as to carry out system installation configuration by using the MAC address of the physical machine to be installed in the following process.

After the configuration center platform responds to the port query task creation operation of the user, the port query task is started to be executed, specifically, the physical machine to be installed is logged in through the IPMI information, and the steps S402 to S403 are executed to obtain the MAC address of the physical machine to be installed, that is, the port query task is completed.

For example, after the configuration center platform responds to a port query task creation operation of a user, the installation information of the physical machine to be installed is submitted to a task dispatch (dispatch) module of the configuration center platform, the dispatch module generates a port query task order of the physical machine to be installed, then the port query task order is distributed to a distributed task scheduling module (cell), the cell calls an installation service module (install), then the install queries the task order according to the port of the physical machine to be installed, logs in the physical machine to be installed through IPMI information, and subsequent step S402 and step S403.

S402, controlling the physical machine to be installed to restart in a PXE mode through an IPMI platform management tool.

The IPMI platform management tool (ipmitool) can command the physical machine to be installed to restart in a PXE mode, so that the physical machine to be installed enters a diskless system mode, and MAC address information, disk information and the like of the physical machine to be installed can be acquired at the moment.

And S403, acquiring the MAC address of the physical machine to be installed from the physical machine to be installed through a PXE server in the configuration center platform.

Since the physical machine to be installed is in the PXE mode after being restarted, the PXE server in the configuration center platform (i.e. the PXE server corresponding to the physical machine to be installed) can acquire the MAC address of the physical machine to be installed from the physical machine to be installed.

Optionally, referring to fig. 5, in an embodiment of the present application, before executing step S103, the method further includes:

s501, inquiring the use state information of the physical machine to be installed through the CMDB.

The CMDB records the use state information of each physical machine to be installed, and when the physical machine is in a state that the operating system is not required to be installed, the use state information of the physical machine recorded by the CMDB is not the state to be installed. For example, when the physical machine to be installed completes the installation of the target operating system, the CMDB records the use state information of the physical machine to be installed as the installed state, and records the use state information of the physical machine that has been installed and put into use as the in-use state.

And when the physical machine to be installed does not install the target operating system, recording the use state information of the physical machine to be installed as the state to be installed in the CMDB. The use state information of the physical machine to be installed is inquired by using the identification information of the physical machine to be installed, and the use state of the current physical machine to be installed can be confirmed, so that the operation system is prevented from being installed again for the physical machine with the operation system installed or the physical machine in production and use.

S502, if the use state information of the physical machine to be installed indicates that the physical machine to be installed is in the state to be installed, calling an IPMI platform management tool to acquire an identification sequence code of the physical machine to be installed.

When the use state information of the physical machine to be installed indicates that the physical machine to be installed is in the state to be installed, it indicates that the physical machine to be installed is not in use and is in a state in which installation of the operating system can be started. And then, acquiring the identification sequence code of the physical machine to be installed by calling an IPMI platform management tool (ipmitool) so as to perform subsequent further verification and verification. Specifically, the ipmitool acquires the identification sequence code of the physical machine to be installed from the physical machine to be installed, where the identification sequence code is a unique sequence code specific to the physical machine to be installed.

S503, judging whether the identification sequence code of the physical machine to be installed, acquired by the IPMI platform management tool, is consistent with the identification sequence code of the physical machine to be installed, stored in the CMDB.

The CMDB stores in advance the identification sequence code of the physical machine to be installed, and if the information of the physical machine to be installed stored in the CMDB is accurate, the identification sequence code of the physical machine to be installed, which is directly acquired from the physical machine to be installed by the IPMI platform management tool, will be consistent with the identification sequence code of the physical machine to be installed stored in the CMDB, and it can be confirmed that the installation information stored in the CMDB should also be correct, so that the subsequent step S504 can be continuously executed. However, if the identifier sequence code of the physical machine to be installed acquired by the IPMI platform management tool is not consistent with the identifier sequence code of the physical machine to be installed stored in the CMDB, it indicates that the installation information of the physical machine to be installed stored in the CMDB may be incorrect, and therefore step S504 cannot be continuously executed, and the process ends.

S504, logging in the physical machine to be installed through IPMI information, and acquiring the MAC address of the physical machine to be installed from the physical machine to be installed.

The execution process and principle of step S504 are the same as step S103, and are not described here again.

S104, binding the MAC address of the physical machine to be installed, and importing the system image file corresponding to the identification information of the target operating system into the physical machine to be installed so as to control the physical machine to be installed to use the system image file to install the target operating system.

The configuration center platform binds the MAC address of the physical machine to be installed, then the MAC address of the physical machine to be installed is utilized to import the system image file corresponding to the identification information of the target operating system into the physical machine to be installed, namely the system image file corresponding to the identification information of the target operating system is controlled and downloaded into the physical machine to be installed, and then the physical machine to be installed is controlled to install the downloaded system image file, so that the target operating system is installed.

The system image file corresponding to the identification information of the target operating system may be understood as a system image file corresponding to the target operating system, and the installation of the system image file corresponding to the target operating system is equivalent to the installation of the target operating system.

Optionally, referring to fig. 6, in an embodiment of the present application, an implementation of step S104 is performed, including:

s601, binding the MAC address of the physical machine to be installed through a network installation server suite on the PXE server, and calling an IPMI platform management tool to control the physical machine to be installed to restart in a PXE mode.

And after the MAC address of the physical machine to be installed is bound, if the physical machine to be installed is in the PXE mode, the cobbler can identify the physical machine to be installed and further execute installation operation. Therefore, the IPMI platform management tool needs to be called to control the physical machine to be installed to restart in the PXE mode. The implementation of the embodiment of the present application is not affected by the MAC address binding of the physical machine to be installed and the execution sequence controlling the physical machine to be installed to restart in the PXE mode.

And S602, after the network installation server suite identifies the physical machine to be installed, importing a system image file corresponding to the identification information of the target operating system into the physical machine to be installed through the network installation server suite so as to control the physical machine to be installed to use the system image file to install the target operating system.

Since the physical machine to be installed is restarted in the PXE mode in step S601, the physical machine to be installed can be identified by the cobbler of the network installation server suite, and after the physical machine to be installed is identified by the network installation server suite, because the cobbler binds the MAC address of the physical machine to be installed, the system image file corresponding to the identification information of the target operating system can be imported into the physical machine to be installed through the network installation server suite, so as to control the physical machine to be installed to use the system image file to install the target operating system.

S105, after the target operating system is installed, configuring the host name of the physical machine to be installed as the target host name, and configuring the IP address of the physical machine to be installed as the target IP address.

After the target operating system is installed, the host name and the IP address of the physical machine to be installed are both temporary, the IP address is temporarily allocated when the target operating system is installed, and the host name is also default for the physical machine to be installed. However, in step S101, the user has a target host name and a target IP address for specifying the physical machine to be installed, and therefore, it is necessary to configure the temporary default host name of the physical machine to be installed as the target host name and then configure the IP address of the physical machine to be installed as the target IP address, so that the IP address and the host name used when the user is handed over to the physical machine to be installed are required by the user.

Optionally, in a specific embodiment of the present application, before performing step S105, the method further includes:

after the target operating system is installed, the temporarily allocated IP address of the physical machine to be installed is obtained through the PXE server, and the temporarily allocated IP address of the physical machine to be installed is accessed by using an Internet Packet explorer (Packet Internet Groper, PING).

The PXE server temporarily allocates a temporary IP address to the physical machine to be installed when the target operating system is installed for the physical machine to be installed, after the operation of the target operating system is completed, in order to ensure that the target operating system is successfully installed, PING is required to access the temporarily allocated IP address of the physical machine to be installed, if the access is successful, the physical machine to be installed is indicated that the target operating system is successfully installed, if the access is not successful, the installation is indicated to be failed, the result of the unsuccessful access can be returned to the configuration center platform, and the configuration center platform performs subsequent processing.

Optionally, the configuration center platform may further record PING access results, and count whether each physical machine to be installed is successfully installed.

Wherein, executing an embodiment of step S105 includes:

If the PING can successfully access the temporarily allocated IP address of the physical machine to be installed, the PING indicates that the physical machine to be installed has successfully installed the target operating system, and therefore the configuration of the host name and the IP address can be continued. Specifically, the target IP address and the target host name are introduced by using the configuration interface of the PXE server, that is, the host name of the physical machine to be installed is configured as the target host name, and the IP address of the physical machine to be installed is configured as the target IP address.

Since the target IP address of the physical machine to be installed has already been configured in step S105, the physical machine to be installed may be controlled by the target IP address, and after the configuration code corresponding to the system configuration service to be configured, which is determined by the operation of the physical machine to be installed, is controlled in the form of inputting a control command to the physical machine to be installed, the physical machine to be installed automatically performs the configuration process of the system configuration service.

and scanning an installation configuration log of the physical machine to be installed, and determining each system configuration service to be configured currently of the physical machine to be installed.

And scanning an installation configuration log of the physical machine to be installed in real time or periodically, wherein the installation configuration log records whether the physical machine to be installed has an installation system or not and whether the configuration of each system configuration service is completed or not. If the system configuration service which is not configured yet by the physical machine to be installed exists in the installation configuration log, the system configuration service is determined to be the system configuration service which is currently configured by the physical machine to be installed, and then step S106 is executed.

After step S106 is executed, the method may further include:

After the physical machine to be installed runs the configuration code determined in step S106, a running result for explaining whether the configuration code is successfully run is written into the installation configuration log. Subsequently, from the operation result written in by the installation configuration log, which system configuration services are successfully installed and which system configuration services are not successfully installed can be read, and further, the system configuration services to be configured can be determined again, and a corresponding configuration task is established to be executed again.

In the prior art, the system configuration of the physical machines is mainly completed by manual operation, and because the services executed by different physical machines may be different, for example, part of the physical machines in an airline company execute a value machine service, and some physical machines execute an international station transportation service, the system configuration needs to be customized manually.
