Based on the above system, the present invention provides a method for managing server clusters. FIG. 2 is a schematic flow diagram of a preferred embodiment of the present invention to implement a method for managing server clusters. As shown in FIG. 2 , the preferred embodiment includes the following steps:

In step S201, the deployment system invokes a remote wake-up tool, and starts the server remotely according to the server ID; the server obtains pre-stored virtualization software, and installs the virtualization software.

Specifically, the WEBGUI module in the configuration analysis system displays the media access control (MAC, MediaAccessControl) address of more than one server in the server resource pool and can install the virtualization software Hypervisor. The MAC address is the unique identifier of the server, and the WEBGUI module receives the user Select the corresponding virtualization software Hypervisor for each MAC address to realize the corresponding relationship between setting servers and virtualization software. The WEBGUI module sends the correspondence between the MAC address and the virtualization software to the diskless workstation of the deployment system, and the shared folder of the diskless workstation stores the correspondence between the MAC address and the virtualization software.

The WEBGUI module receives the running script input by the user, which contains the MAC address of the server, and the WEBGUI module provides the running script to the network service module of the deployment system; the Dynamic Address Resolution Protocol (DHCP, DynamicHostConfigurationProtocol) server in the network service module calls the running Script, run the script to run the remote wake-up tool (such as ether-wake software), the remote wake-up tool remotely starts the corresponding server through the network according to the MAC address in the running script, where the input MAC address can be the MAC address of more than one server, so , you can start more than one server at the same time. At the same time, the DHCP server assigns the corresponding IP address to the server, sends the assigned IP address to the server, and saves the corresponding relationship between the server's IP address and MAC address to the Trivial File Transfer Protocol (TFTP, Trivial File Transfer Protocol) server of the diskless workstation. In this preferred embodiment, the user refers to the administrator of the server cluster.

The WEBGUI module receives the initialization information uploaded by the user and configured for each server. The initialization information includes initialization programs, root files, and system boot configuration information. The WEBGUI module sends the received initialization information and the MAC address of the corresponding server to the diskless The workstation, the folder of the TFTP server of the diskless workstation saves the initialization information and the corresponding MAC address. After the server is successfully started, the server sends a request carrying the assigned IP address to the diskless workstation in the network service module, and the TFTP server of the diskless workstation finds the corresponding IP address according to the stored correspondence between the IP address and the MAC address. MAC address, and then according to the MAC address, find the corresponding initialization information in the corresponding relationship between the MAC address and the initialization information, and return the found initialization information to the server. After the server receives the initialization information, the initialization program in the initialization information will guide The server performs the initialization work before the virtualization software installation. When performing initialization, the server completes the initialization work before the virtualization software installation according to the root file and the system boot configuration information in the initialization information received.

After the server is initialized, the server accesses the shared folder of the diskless workstation according to the system boot configuration information, and obtains the installation of the corresponding virtualization software from the shared folder according to the corresponding relationship between the MAC address and the virtualization software in the shared folder. Image, the installation image of the virtualization software can be uploaded to the shared folder in advance by the user; the installation image of the virtualization software contains the configuration file required for automatic installation of the virtualization software, and the configuration file is named after ks.cfg , including the installation package of virtualization software, the virtualization software can be free virtualization software such as XEN, KVM; the server runs the installation package, and automatically installs the virtualization software.

The diskless workstation obtains the operating status of the server in real time through the interface API provided by the virtualization software. When the diskless workstation detects that the virtualization software has been installed on the server, it sends a system optimization script to the server for optimal configuration of the server. The optimization script includes simplification of startup service information, memory usage of the solidified host, etc. The system optimization script is a script written by the user received by the WEBGUI module, and the WEBGUI module sends the system optimization script written by the user to the diskless workstation for storage. According to the system optimization script, the server optimizes its own virtualization software, for example, cancels some startup services, configures the memory used by its own host, and so on. After the optimization process, the server is restarted, and the virtualization system in the server is successfully installed.

Step S202, the server runs a preset configuration script to generate a virtual machine; the configuration script is pre-generated according to the configured virtual machine allocation scheme.

In this way, the analysis module The virtual machine allocation scheme is parsed into a configuration script that can be recognized and invoked by the virtualization software, and the name of the generated configuration script is the MAC address of the server.

The parsing module sends the generated configuration script to the diskless workstation, and the diskless workstation finds the corresponding IP address in the corresponding relationship between the MAC address and the IP address of the server according to the name of the configuration script, and then converts the configuration script according to the found IP address. Send to the server corresponding to the IP address in the way of Secure Sockets Layer (SSL, SecureSocketsLayer) protocol. Here, if there is no corresponding configuration script for the IP address, it means that the servers corresponding to these IP addresses will use the default method to allocate virtual machines, so the parsing module will send the default configuration script pre-configured by the user to the servers corresponding to these IP addresses.

After the server receives the configuration script from the diskless workstation, it runs the configuration script with the virtualization software, and then automatically generates virtual machines according to the number of deployed virtual machines, and automatically completes the performance configuration of the virtual machines according to the performance configuration information of the virtual machines , such as the hard disk allocated to the virtual machine.

Step S203, the server uses the virtualization software to control the virtual machine to load the pre-generated system installation image.

Specifically, the WEBGUI module receives the operating system installation plan configured by the user for the virtual machine on the server. The operating system installation plan includes directory storage format, storage partition, time zone, keyboard type, network distribution method, and software packages to be installed; WEBGUI will The received operating system installation scheme is recorded into a file, and the file is sent to the parsing module; the parsing module uses parsing tools (such as awk and sed tools) to parse the operating system installation scheme into a configuration file that can be recognized by the virtualization software.

The parsing module sends the analyzed configuration file to the image storage module, and the image storage module invokes the configuration file using the MIKSOFS command or the FAI command to generate a system installation image, and the image storage module stores the generated system installation image.

The server uses the virtualization software to mount the image storage module storing the system installation image to the virtual machine, and the virtual machine automatically loads the system installation image to realize the automatic installation of the virtual machine operating system.
