Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The cloud host mirror image synchronization method provided by the application can be applied to the application environment shown in fig. 1. The application environment includes a server cluster divided into a plurality of available zones. And each available area is provided with a control node, a file server and a non-file server. The file server is implemented by using an independent server or a server cluster consisting of a plurality of servers.
In an embodiment, as shown in fig. 2, a synchronization method for cloud host images is provided, which is described by taking the method as an example for being applied to the control node in fig. 1, and includes the following steps:
In this embodiment, the control node receives the mirror image synchronization instruction, and then determines a synchronization processing mode of the cloud host mirror image according to a sending end of the mirror image synchronization instruction.
The first method is as follows: and receiving a mirror image synchronization instruction sent by a front-end browser. After receiving the mirror image synchronization instruction sent by the front-end browser, the control node of the available area calls the control nodes of other available areas to perform cross-area synchronization processing, that is, sends the mirror image synchronization instruction to the control nodes of other available areas, as shown in fig. 3. Meanwhile, the non-file servers in the same available area are subjected to the same area synchronization process, that is, step 203 is executed.
For example, the available area includes a test available area, a production available area, and a disaster recovery available area; the control node of the test available area receives a mirror image synchronization instruction sent by a front-end browser, and then the control node of the test available area respectively calls the control node of the production available area and the control node of the disaster recovery available area to perform cross-area synchronization processing; meanwhile, the non-file servers in the test available area are subjected to the same-area synchronization process, which is shown in fig. 3.
The second method comprises the following steps: and receiving mirror image synchronization commands sent by the control nodes of other available areas, and executing the step 202 and the step 203 in sequence by the control nodes of the available areas according to the mirror image synchronization commands.
For example, when the control node of the test available area calls the control node of the generated available area to perform cross-area synchronization processing, the control node of the production available area receives a mirror image synchronization instruction sent by the control node of the test available area. Then, the control node that produces the usable area executes step 202 and step 203 in order.
In one embodiment, after receiving the mirror synchronization instruction sent by the front-end browser, the method further includes: acquiring a preset configuration file; the configuration file stores the network protocol addresses of the control nodes of other available areas; and sending mirror image synchronization instructions to the control nodes of other available areas according to the configuration file.
Specifically, a configuration file is set in the control node in advance, and network protocol addresses of the control nodes of other available areas are stored in the configuration file. After the control node receives a mirror image synchronization instruction sent by a front-end browser, network protocol addresses of control nodes of other available areas are obtained from a preset configuration file, the control nodes of the other available areas are called according to the obtained network protocol addresses, and the mirror image synchronization instruction is sent according to the obtained network protocol addresses.
For example, after receiving a mirror image synchronization instruction sent by a front-end browser, a control node in the test available area acquires a configuration file preset in the control node, where a network protocol address IP1 of the control node in the production available area and a network protocol address IP2 of the control node in the disaster recovery available area are stored in the configuration file. And then, the control node of the test available area sends a mirror image synchronization instruction to the control node of the production available area according to the network protocol address IP1, and sends a mirror image synchronization instruction to the control node of the disaster recovery available area according to the network protocol address IP 2.
The configuration file may also store an API (Application Programming Interface) of a control node in another available area.
In one embodiment, the available region includes a test available region and a plurality of non-test available regions; the control node of the test available area transmits data to the control nodes of the plurality of non-test available areas in a unidirectional mode; and data is transmitted bidirectionally among the control nodes of the plurality of non-test available areas.
Specifically, the available area includes a test available area and a plurality of non-test available areas such as a production available area and a disaster recovery available area. The cloud host image testing method comprises the steps that a newly manufactured cloud host image and an updated cloud host image are stored in a testing available area, and a user-defined cloud host image is stored in a non-testing available area.
In practical application, the control node of the test available area may call the control node of the production available area and the control node of the disaster recovery available area, so as to synchronize the cloud host mirror image stored in the test available area to the production available area and the disaster recovery available area. However, in order to avoid affecting the newly manufactured cloud host mirror image and the updated cloud host mirror image, neither the control node of the production available area nor the disaster recovery available area can call the control node of the test available area, that is, neither the production available area nor the disaster recovery available area can synchronize the cloud host mirror image to the test available area. The production available area and the disaster recovery available area are both non-test available areas, the control node of the production available area can call the control node of the disaster recovery available area, and the control node of the disaster recovery available area can also call the control node of the production available area, that is, the production available area can synchronize the cloud host mirror image to the disaster recovery available area, and the disaster recovery available area can also synchronize the cloud host mirror image to the production available area. The non-test available area is not limited in detail in the embodiment of the invention, and can be set according to actual conditions.
In this embodiment, if the control node receives the mirror synchronization instruction sent by the control node in another available area, the control node sends a cross-area synchronization instruction to the first file server in the same available area. And the first file server determines a second file server of an available area where the mirror image synchronization instruction sending end is located according to the cross-area synchronization instruction, and then downloads the cloud host mirror image from the second file server and stores the cloud host mirror image.
For example, the first file server is a file server that produces usable areas, and the second file server is a file server that tests the usable areas. And after receiving the mirror image synchronization instruction sent by the control node of the test available area, the control node of the production available area sends a cross-area synchronization instruction to the first file server. After receiving the cross-region synchronization instruction, the first file server determines a second server according to the cross-region synchronization instruction, then downloads the cloud host image from the second server, and stores the cloud host image, as shown in fig. 3. The storage position is not limited in detail in the embodiment of the invention, and can be set according to actual conditions.
In one embodiment, after the first file server downloads the cloud host image from the second file server, the control node in the same available area as the first file server feeds back the synchronization processing result to the control node in the same available area as the second file server.
For example, the first file server is a file server for producing the available area, the second file server is a file server for testing the available area, and after the first file server downloads the cloud host image from the second file server, the control node for producing the available area feeds back to the control node for testing the available area that the downloading of the cloud host image is completed.
In this embodiment, after receiving a mirror image synchronization instruction sent by a front-end browser, a control node calls control nodes in other available areas to perform cross-area synchronization processing, and also performs same-area synchronization processing, that is, a cloud host mirror image stored by a file server in the same available area is distributed to each non-file server in the same available area. Specifically, a synchronization instruction of the same region is sent to the non-file servers of the same available region, and after receiving the synchronization instruction of the same region, the non-file servers of the same available region download the cloud host image from the file servers of the same available region and store the cloud host image.
For example, the first file server is a file server of the test available area, and after receiving the mirror image synchronization instruction sent by the front-end browser, the control node of the test available area sends the mirror image synchronization instruction to the control node of the production available area and the control node of the disaster recovery available area, and also sends the synchronization instruction of the same area to a non-file server in the test available area. After each non-file server of the test available area receives the synchronization instruction of the same area, the cloud host image is downloaded from the first file server, and the cloud host image is stored, which is shown in fig. 3. The non-file server downloads the cloud host mirror image from the file server and can adopt an Http file service mode, namely, the file server transmits the cloud host mirror image to the non-file server through an Http80 port.
Or after the first file server downloads the cloud host mirror image from the second file server and stores the cloud host mirror image, the control node sends a synchronization instruction of the same region to the non-file server in the same available region, and after receiving the synchronization instruction of the same region, the non-file server downloads and stores the cloud host mirror image from the first file server.
For example, the first file server is a file server of a production available area, the second file server is a file server of a test available area, after the first file server downloads a cloud host image from the second file server and stores the cloud host image, the control node of the production available area sends a synchronization instruction of the same area to the non-file server of the production available area, and after the non-file server of the production available area receives the synchronization instruction of the same area, the cloud host image is downloaded from the first file server and stored.
In one embodiment, after the non-file server downloads the cloud host image from the file server, the control node feeds back a synchronization processing result to a front-end browser or a control node in another available area.
For example, the first file server is a file server for testing the available area, and after the non-file server downloads the cloud host image from the file server, the control node for testing the available area feeds back the cloud host image distribution processing of the tested available area to the front-end browser. Or the first file server is a file server for producing the available area, the second file server is a file server for testing the available area, and after the first file server downloads and stores the cloud host mirror image from the second file server, the non-file server for producing the available area downloads and stores the cloud host mirror image from the first file server; and then, the control node of the production available area feeds back the cloud host image distribution processing of the finished production available area to the control node of the test available area.
In the synchronization method of the cloud host mirror image, the control node receives a mirror image synchronization instruction; sending a cross-region synchronization instruction to a first file server in the same available region according to the mirror image synchronization instruction; and according to the mirror image synchronization instruction, sending a synchronization instruction of the same region to a non-file server of the same available region. By the embodiment of the invention, cross-region synchronous processing and same-region synchronous processing of the cloud host mirror image can be realized, manual copying is not needed, time and labor are saved, and the problem of errors in manual copying can be avoided. Furthermore, as each available area is provided with a control node and a file server, the control and the cloud host mirror image storage are classified, and the data security is improved.
In an embodiment, as shown in fig. 4, a synchronization method for cloud host images is provided, which is described by taking the method as an example for being applied to the file server in fig. 1, and includes the following steps:
In this embodiment, when performing synchronization processing of a cloud host image, a control node sends a cross-region synchronization instruction to a file server in the same available region, and the file server receives the cross-region synchronization instruction sent by the control node. For example, a file server of the test available area receives a cross-area synchronization instruction sent by a control node of the test available area; the file server of the production available area receives the cross-area synchronization command sent by the control node of the production available area, which is shown in fig. 3.
In one embodiment, before receiving the cross-zone synchronization instruction sent by the control nodes of the same available zone, the method further includes: installing a service component in a file server; the service component is used for establishing a control channel between the file server and the control node in the same available area, a transmission channel between the file server and a non-file server in the same available area, and a transmission channel between the file server and file servers in other available areas.
Specifically, the service component is pre-installed in the file server, after installation, the service component may establish a control channel between the control node and the file server in the same available area, and through the control channel, the control node may send a cross-area synchronization instruction to the file server. The service assembly can also establish a transmission channel between the file server and the non-file server in the same available area, and the non-file server can download the cloud host mirror image from the file server in the same available area through the transmission channel; and a transmission channel between the file server and the file servers in other available areas can be established, and the file server can download the cloud host images from the file servers in other available areas through the transmission channel.
For example, a service component is installed in a file server of a production available area in advance, the service component establishes a control channel between a control node and the file server in the production available area, a transmission channel between the file server of the production available area and a non-file server, and a transmission channel between the file server of the production available area and a file server of a test available area.
And 302, downloading the cloud host image from the file servers of other available areas according to the cross-area synchronization instruction.
In this embodiment, after receiving the cross-region synchronization instruction sent by the control node, the file server downloads the cloud host image from the file servers in other available regions. Specifically, the first file server is a server for downloading a cloud host image, and the second server is a file server of other available areas. And after receiving the mirror image synchronization instruction sent by the control nodes in other available areas, the control node in the same available area as the first file server sends a cross-area synchronization instruction to the first file server. After receiving the cross-region synchronization instruction, the first file server can determine an available region where the mirror image synchronization instruction sending end is located according to the cross-region synchronization instruction, so that the second file server is determined, and the cloud host mirror image is downloaded from the second file server.
For example, the file server that produces the usable area is the first file server, and the file server that tests the usable area is the second file server. And after the control node of the production available area receives the mirror image synchronization instruction sent by the control node of the test available area, the control node of the production available area sends a cross-area synchronization instruction to the first file server. After the first file server receives the cross-region synchronization instruction, the control node which sends the mirror image synchronization instruction and is used for testing the available region is determined according to the cross-region synchronization instruction, and then the cloud host mirror image is determined to be downloaded from the second file server which tests the available region.
In this embodiment, the file server may mount the mirror storage volume in advance, that is, mount the hardware storage device in advance. And after the cloud host mirror image is downloaded, storing the cloud host mirror image into a mirror storage volume. After the cloud host mirror image is stored, the control node in the same available area can be fed back that the storage processing of the cloud host mirror image is completed.
In the synchronization method of the cloud host mirror image, a file server receives a cross-region synchronization instruction sent by control nodes in the same available region; downloading cloud host mirror images from file servers of other available areas according to the cross-area synchronization instruction; and storing the cloud host mirror image into a mirror storage volume which is mounted in advance. According to the embodiment of the invention, when the cross-region synchronization processing of the cloud host mirror image is carried out, the file server can automatically download the cloud host mirror image from the file servers of other available regions according to the cross-region synchronization instruction sent by the control node, and store the cloud host mirror image, so that not only is the time and labor saved, but also the problem of errors caused by manual copying can be avoided.
In an embodiment, as shown in fig. 5, a synchronization method for cloud host images is provided, which is described by taking the method as an example for being applied to the non-file server in fig. 1, and includes the following steps:
In this embodiment, the non-file server receives a synchronization instruction in the same area sent by the control node in the same available area. For example, the control node of the test available area receives the mirror synchronization command from the front-end browser, and then the control node of the test available area sends the same area synchronization command to the non-file server of the same available area. Or the control node of the production available area receives the mirror image synchronization instruction from the control node of the test available area, and then the control node of the production available area sends the synchronization instruction of the same area to the non-file server; and the non-file server receives the synchronization instruction of the same region sent by the control node.
In the embodiment, a non-file server presets a mirror image storage directory, and downloads a cloud host mirror image from a file server in the same available area after receiving a synchronization instruction in the same area, namely downloads the cloud host mirror image from a mirror image storage volume mounted by the file server; and then, storing the cloud host image into an image storage catalog.
For example, the non-file server of the test available area downloads the cloud host image from the file server of the test available area and stores the cloud host image; alternatively, the non-file server of the production availability region downloads the cloud host image from the file server of the production availability region and stores the cloud host image.
And 403, checking the cloud host mirror image, and feeding back successful synchronization to the control node when the check is passed.
In this embodiment, after downloading the cloud host image, the non-file server may perform MD5 verification on the cloud host image. Specifically, performing MD5 operation on the cloud host mirror image, comparing an obtained calculation result with a preset check code, and determining that the check is passed if the calculation result is consistent with the check code; and if the calculation result is inconsistent with the check code, determining that the check fails.
After the verification is passed, the non-file server can feed back the downloading and storage of the cloud host mirror image to the control node in the same available area, namely, the feedback synchronization is successful. For example, the non-file server in the test available area feeds back the completed cloud host image synchronization processing to the control node in the test available area, and the control node in the test available area may feed back the completed cloud host image synchronization processing to the front-end browser.
After the verification fails, the non-file server may feed back the verification failure to the control node in the same available area.
