Description

Cloud host resource migration method and device, communication equipment and storage medium
Technical Field
The invention relates to the technical field of communication, in particular to a method and a device for migrating cross-platform cloud host resources, communication equipment and a storage medium.
Background
Infrastructure as a Service (IaaS) provides virtual computing resources, storage resources and network resources for users, and facilitates the operation of upper-layer applications. Currently, there are multiple software vendors such as VMware cloud platform and Openstack cloud platform that provide solutions for infrastructure as a service. Thus, it is often the case that cloud host data is migrated from between platforms of two different architectures. Currently, there are two main methods in the industry for migrating cloud host resources from a VMware cloud platform to a heterogeneous cloud platform:
firstly, a file migration mode is adopted, namely parameters which are the same as the cloud host configuration of the VMware of the original cloud platform are manually input on the target cloud platform, so that a user is newly built on the target cloud platform, a virtual machine is built under the user account, and then resources in the original cloud host are uploaded to the target cloud host. After the migration is finished, in order to ensure that the target cloud host operates normally, the registry of the target cloud host needs to be modified;
secondly, a mirror image migration mode is adopted, namely a cloud host is established on a target cloud platform, and template information and an IP (Internet Protocol Address) Address of the cloud host are set; and acquiring the image file of the cloud host from the VMware of the original cloud platform, and importing the image file of the injected drive file into the newly created cloud host.
In addition, the existing solutions all require manual input of configuration parameters to configure the cloud host, so that the existing method for migrating the cloud host from the VMware cloud platform to the heterogeneous cloud platform inevitably has the problems of low migration efficiency and high error rate.
Moreover, the architecture of the VMware cloud platform (VMware Workstations) comprises a vsphere Client (vsphere Client), a Vcenter Server (Vcenter Server) and an ESXi Server. The established virtual machines are established on the ESxi server, a plurality of virtual machines can be established on one ESxi server, the ESxi servers can form a server cluster, and all the ESxi servers in the cluster are uniformly managed through the vcenter server. Because the resources of the ESxi server are all obtained from the vcenter server in the prior art, even if the space occupied by the resources needing to be transferred in the virtual machine is only 10G, the whole disk occupied by the resources needing to be transferred in the ESxi server needs to be converted into an image file, and the size of the image file can be 100G, so that the processing pressure of the server is increased greatly due to the fact that the transmission channel of the vcenter server is occupied.
In summary, the existing method for migrating the cloud host from the VMware cloud platform to the heterogeneous cloud platform inevitably has the problems of low migration efficiency, high error rate and high processing pressure of the server.

The technical solutions in the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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.
The first embodiment is as follows:
referring to fig. 1, an embodiment of the present invention provides a method for migrating a cross-platform cloud host resource, including:
s110, acquiring an initial image file corresponding to an original cloud host from an ESxi server;
s120, supplementing the first configuration data according to the second configuration data; determining target configuration data according to a preset migration rule and the supplemented first configuration data; determining a target image file according to a preset migration rule and an initial image file; the first configuration data is the configuration data of the original cloud host acquired from the vcenter server, and the second configuration data is the configuration data of the cloud host in the initial image file;
s130, creating a target cloud host on the target cloud platform, and loading a target image file and target configuration data in the process of creating the target cloud host.
By the cloud host resource migration method provided by the embodiment of the invention, a user can automatically set the migration rule of the cloud host to realize the automatic migration of the cross-platform cloud host resource, thereby reducing the error rate caused by manually inputting the configuration parameters and improving the migration efficiency of the cloud host resource. Meanwhile, the method for acquiring the mirror image file from the ESxi server and acquiring the configuration data of the original cloud host from the vcenter server realizes multi-path acquisition of migration data and shortens the time required by migration.
For step S120, supplementing the first configuration data according to the disk information in the second configuration data, including:
firstly, determining the number of system disks and data disks according to second configuration data, wherein the specific method comprises the following steps:
first, whether the number of disks in the second configuration data is the same as the number of disks in the first configuration data is judged. Generally, the number of disks in the first configuration data and the second configuration data is the same; and if the number of the disks in the first configuration data is different from the number of the disks in the second configuration data, prompting error information.
And determining the number of the system disks and the number of the data disks according to the number of the disks in the second configuration data. That is, if only one disk is configured in the second configuration data, the disk is determined to be a system disk. If the second configuration data is configured with at least two disks, determining whether the original cloud host manages the disks in a disk management mode of the logical volume according to the second configuration data; if so, determining the number of the system disks and the number of the data disks in the disk management mode of the logical volume; otherwise, directly determining that the number of the system disks is one, and the other disks are all data disks, and supplementing the number of the system disks and the number of the data disks in the first configuration data by taking the determined number of the system disks and the determined number of the data disks as a standard.
Secondly, determining the capacity corresponding to the system disk and the capacity corresponding to the data disk according to the capacity corresponding to the disk in the second configuration data; and supplementing the capacity corresponding to the system disk and the capacity corresponding to the data disk in the first configuration data with the determined capacity corresponding to the system disk and the determined capacity corresponding to the data disk.
Finally, determining the name corresponding to the system disk and the name corresponding to the data disk according to the name corresponding to the disk in the second configuration data; and supplementing the name corresponding to the system disk and the name corresponding to the data disk in the first configuration data with the determined name corresponding to the system disk and the determined name corresponding to the data disk.
For step S120, determining whether a modification rule for the disk information is defined in the preset migration rule, modifying the disk information in the supplemented first configuration data if the modification rule for the disk information is defined, and determining that the disk information in the supplemented first configuration data is the disk information in the target configuration data; and if the preset migration rule does not limit the modification rule of the disk information, determining that the disk information in the first configuration data is the disk information in the target configuration data. The disk information includes the number of disks, the disk capacity, and the disk name.
The system disk and the data disk can be distinguished by distinguishing the types of the disks in the original cloud host, namely distinguishing the system disk and the data disk, so that the problem that the system disk and the data disk can not be distinguished by a disk management mode aiming at a logical volume in the prior art is solved.
For step S120, supplementing the first configuration data according to the network card information in the second configuration data, including:
firstly, judging whether the number of the network cards in the second configuration data is the same as that of the network cards in the first configuration data, and if so, taking the number of the network cards in the first configuration data as a standard; if the configuration data is the same as the network cards in the first configuration data, the number of the network cards in the first configuration data does not need to be changed.
Secondly, if the first configuration data does not have an IP (Internet Protocol) address corresponding to the network card, the IP address corresponding to the network card in the first configuration data is supplemented according to the IP address corresponding to the network card in the second configuration data.
Aiming at the step S120, modifying the first configuration data supplemented with the network card information according to a preset migration rule, including:
if only one network card is configured in the original cloud host and the allocation mode of the IP address in the original cloud platform is a static allocation mode, determining the IP address corresponding to the network card in the target configuration data according to the IP address corresponding to the network card in the first configuration data and a preset migration rule; if the original cloud host is configured with at least two network cards, determining an allocation mode of an IP address corresponding to the network card according to a preset migration rule; if the allocation mode of the IP address is a static allocation mode, determining the IP address corresponding to the network card of the cloud host in the target platform according to the IP address corresponding to the network card in the first configuration data and a preset migration rule; if the allocation mode of the IP address is a DHCP (Dynamic Host Configuration Protocol) allocation mode, determining a network where the target cloud platform is located according to a name of a network where the original platform is located in the first Configuration data and a preset migration rule, and acquiring an IP address corresponding to a network card in the target Configuration data from an IP address pool corresponding to the network where the target cloud platform is located; and executing the method for all the network cards in the first configuration data to reset the IP addresses corresponding to the network cards. In any IP address allocation manner, the network information of the target cloud platform is generated according to the network information of the original cloud platform in the first configuration data and the preset migration rule, and finally, a network corresponding to the network information of the target cloud platform is created on the target cloud platform.
By resetting the configuration file corresponding to the network card in the image file, the newly-built network card in the target cloud host supports dynamic IP address acquisition in a DHCP mode.
For step S120, obtaining a target image file according to a preset migration rule and the initial image file, including:
if the preset migration rule specifies the modification mode of the image file, modifying the IP address distribution mode in the initial image file according to the preset migration rule, and determining the modified image file as the target image file.
And if the preset migration rule does not specify the modification mode of the image file, directly determining that the initial image file is the target image file.
By configuring the network card information according to the preset migration rule, the problem that a target cloud host cannot automatically acquire an IP address when the cloud host is migrated through the mirror image file is solved, and the problem that the network card information stored in the vcenter server is incomplete or wrong is also solved.
Before determining the target image file, the method further comprises:
if the initial image file is modified, injecting a drive file of the target cloud platform into the modified initial image file; and if the initial image file is not modified, injecting a drive file of the target cloud platform into the initial image file.
With respect to step S130, before creating the target cloud host, the method further includes:
and uploading the target image file determined in the step S120 to a target cloud platform.
For step S130, the method of creating a target cloud host:
acquiring user information of a primary cloud platform from a vcenter server;
and according to the user information of the original cloud platform, a user is newly built on the target cloud platform, and a target cloud host is built under the newly built user.
Wherein, the user information of the original cloud platform comprises: a user account and a right item corresponding to the user account;
according to the user information of the original cloud platform, a new user is established on the target cloud platform, and the method comprises the following steps:
according to a user account registered on an original cloud platform, a user is newly built on a target cloud platform by using the user account; and setting corresponding authority for the newly-built user according to the corresponding authority of the user account.
If the user information of the original cloud platform further includes a password corresponding to the user account, after the user is newly created, the method further includes: setting a password corresponding to the user account as a newly-established password corresponding to the user;
if the user information of the original cloud platform does not store the password corresponding to the user account, after the user is newly created, the method further comprises the following steps: and setting the password corresponding to the user account as a preset initial password.
By the method for creating the target cloud host, the problem that in the prior art, when cloud host resources are migrated, the migrated resources are only packaged integrally and are not distinguished by taking a user as a unit, so that authority management on the resources migrated by the target cloud host cannot be realized is solved.
Example two:
the second embodiment of the present invention provides a method for migrating cloud host resources from a VMware cloud platform to an Openstack cloud platform, and referring to fig. 2, the method specifically includes:
s200, determining a cloud host to be migrated in the VMware cloud platform according to a migration rule preset by a user; because part of the cloud hosts created in the VMware cloud platform are used for testing and do not need to be migrated, the migration rule preset by the user specifies the conditions of the cloud hosts which do not need to be migrated;
s210, acquiring configuration data of an original cloud host to be migrated, user information and a mirror image file corresponding to the original cloud host from a VMware cloud platform; specifically, the acquisition of information may be achieved by:
s211, acquiring configuration data of a primary cloud host created on a VMware cloud platform through an Application Programming Interface (API) of a vcenter server, and determining the configuration data as first configuration data; wherein the first configuration data comprises: the name of the original cloud host, the memory of the original cloud host, the processor, the cluster where the original cloud host is located, the disk information and the network card information. The disk information comprises the number of disks in the original cloud host, the corresponding size of the disks and the names of the disks; the network card information includes the number of network cards in the original cloud host, the IP address corresponding to the network cards, and CIDR (Classless inter domain Routing, no class inter-domain Routing).
S212, obtaining user information from a vcenter server; the user information comprises a user account and a permission corresponding to the user account; namely, whether the user is an administrator or not and whether the operation can be executed with the authority of the administrator or not is determined; in addition, the acquired user information may further include a password corresponding to the user account.
S213, the initial image file corresponding to the primary cloud host is directly obtained from the ESxi server through the ovftool tool, and because the image file obtained from the vcenter server has a large amount of reserved space but is not actually occupied, the efficiency of obtaining the image file corresponding to the primary cloud host from the vcenter server is low, and the problem that the initial image file is directly obtained from the ESxi server can be avoided.
S220, calling a libgustfs function, acquiring configuration data of the primary cloud host from the image file acquired in the step S213, and determining that the configuration data is second configuration data.
The primary cloud host is a multi-disk cloud host, so that whether the primary cloud host manages the disk in a disk management mode of the logical volume is determined according to the second configuration data; if so, determining the number of the system disks and the number of the data disks in a disk management mode of the logical volume; supplementing the number of the system disks and the number of the data disks in the first configuration data according to the determined number of the system disks and the determined number of the data disks;
determining the capacity corresponding to the system disk and the capacity corresponding to the data disk according to the capacity corresponding to the disk in the second configuration data; supplementing the capacity corresponding to the system disk and the capacity corresponding to the data disk in the first configuration data by the determined capacity corresponding to the system disk and the determined capacity corresponding to the data disk;
determining a name corresponding to the system disk and a name corresponding to the data disk according to the name corresponding to the disk in the second configuration data; and supplementing the name corresponding to the system disk and the name corresponding to the data disk in the first configuration data with the determined name corresponding to the system disk and the determined name corresponding to the data disk.
The original cloud host is a cloud host with multiple network cards, so that whether the number of the network cards in the second configuration data is the same as that of the network cards in the first configuration data or not is judged, and if the number of the network cards in the first configuration data is different, the number of the network cards in the first configuration data is used as the standard; if the configuration data are the same, the number of the network cards in the first configuration data does not need to be changed;
and judging whether the network card in the first configuration data corresponds to the IP address, if not, supplementing the IP address corresponding to the network card in the first configuration data according to the IP address corresponding to the network card in the second configuration data.
S230, determining target configuration data according to a migration rule preset by a user and the supplemented first configuration data, and setting whether the IP address allocation mode in the initial image file is a DHCP allocation mode or a static allocation mode according to the migration rule preset by the user, so as to determine the target image file. Specifically, the migration rule includes a mapping rule of a name of the cloud host, a mapping rule of the processor, a mapping rule of the memory, a mapping rule of the number of disks, a mapping rule of a disk specification, a mapping rule of the number of network cards, a mapping rule of a network corresponding to the network cards, and a mapping rule of an IP address corresponding to the network cards.
In this embodiment, the name of the cloud host is mapped according to a rule that the name of the target cloud host is the same as the name of the original cloud host;
the mapping rule of the processor is that the configuration data of the processor in the target cloud host is the same as the configuration data of the processor in the original cloud host;
