While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
Fig. 1 is a schematic flowchart illustrating a migration method of microservices in multiple rooms according to a first embodiment of the present invention, where as shown in fig. 1, the method includes the following steps:
step S101, according to the data migration request aiming at the micro service to be migrated, determining a source host computer room and a target host computer room corresponding to the micro service to be migrated.
Specifically, a master room and a slave room are configured in advance for each micro service in a configuration center, the micro service refers to a service which can be deployed independently and has high cohesion characteristics, and the characteristics of low coupling between different micro services are also provided. One skilled in the art can configure the master machine room and the slave machine room for each microservice according to actual needs to ensure balanced flow of the machine rooms. Assuming that the e-book reading server includes 4 micro-services, the 4 micro-services are respectively micro-service a to micro-service D, and the e-book reading server corresponds to 2 rooms, respectively room 1 and room 2, the room 1 may be configured as a master room of the micro-service a and micro-service B, the room 2 may be configured as a slave room of the micro-service a and micro-service B, and in addition, the room 2 may be configured as a master room of the micro-service C and micro-service D, and the room 1 may be configured as a slave room of the micro-service C and micro-service D.
The main machine room of the micro-service is used for providing external data access for each micro-service, and when the main machine room provides the external data access, the auxiliary machine room does not provide the external data access and is used as hot standby. When the traffic of a plurality of machine rooms is unbalanced or a network condition of a certain machine room is abnormal, one or more micro-services need to be migrated from an original host machine room to other machine rooms, and the other machine rooms continue to provide access to external data. In the invention, the micro-service to be migrated is called the micro-service to be migrated, the original host room corresponding to the micro-service to be migrated is called the source host room corresponding to the micro-service to be migrated, and the other machine rooms to which the micro-service to be migrated needs to be migrated are called the target host rooms corresponding to the micro-service to be migrated.
When the micro service migration requirement exists, triggering a data migration request aiming at the micro service to be migrated, wherein the data migration request can comprise: the micro-service identifier to be migrated may be a name of the micro-service to be migrated or a micro-service ID of the micro-service to be migrated. Then, in step S101, a source host room corresponding to the micro service to be migrated may be determined according to the source host room identifier in the data migration request, and a target host room corresponding to the micro service to be migrated may be determined according to the target host room identifier in the data migration request.
And S102, utilizing the switch component to close the external data access of the micro service to be migrated in the source host computer room.
In order to effectively manage and control the external data access of each micro-service in a plurality of machine rooms, the invention adds a switch component on the basis of the existing multi-machine-room management technology, after the configuration center completes the configuration of the main machine room and the slave machine room of each micro-service, for each micro-service, the switch component is utilized to open the external data access of the micro-service in the corresponding main machine room, and close the external data access of the micro-service in the corresponding slave machine room. After the source host computer room corresponding to the micro service to be migrated is determined in step S101, the switch component may be used to close the external data access of the micro service to be migrated in the source host computer room, so that the source host computer room may no longer receive the data access request for the micro service to be migrated.
Step S103, generating probe data, writing the probe data into the data access log of the source host computer room, and synchronizing the data access log of the source host computer room to the target host computer room.
Data synchronization needs to be completed between the source host computer room and the target host computer room to ensure that the target host computer room can provide reliable service. And due to the influence of the data transmission rate of the network link and the rate of reading the data access logs, the data synchronization among a plurality of computer rooms is delayed. In order to effectively identify whether data synchronization is completed between the source host computer room and the target host computer room, probe data is generated after the switch component is utilized to close the external data access of the micro service to be migrated in the source host computer room, the probe data can be data without actual operation meaning, and a person skilled in the art can set the specific content of the probe data according to actual needs, and the method is not limited herein.
After the probe data is generated, writing the probe data into a data access log of the source host computer room, and synchronizing the data access log of the source host computer room to the target host computer room. Specifically, in addition to writing the probe data, the data access log of the source host room also writes an operation instruction of a data write operation performed by the source host room for the micro service to be migrated before the write position of the probe data, that is, in the data access log of the source host room, the write position of the probe data is located after the operation instruction of all data write operations performed by the source host room for the micro service to be migrated, and is used for identifying the end of data synchronization between the source host room and the target host room. And synchronizing the data access log of the source host computer room to the target host computer room so that the target host computer room can read the data access log to update the database.
And step S104, reading the data access log by the target host room to update the database, and starting external data access of the micro service to be migrated in the target host room by using the switch assembly when the probe data is read.
And the target host computer room reads the data access log of the source host computer room, and writes the data into the database of the target host computer room by executing the data writing operation recorded in the data access log, thereby realizing the updating of the database. When the target host computer room reads probe data in the data access log, it is indicated that the target host computer room has completed executing all data write-in operations executed by the source host computer room for the micro service to be migrated, that is, data synchronization is completed between the source host computer room and the target host computer room, and the target host computer room can already provide reliable service for the micro service to be migrated, then the switch assembly is used to start external data access of the micro service to be migrated in the target host computer room, so that the target host computer room provides external data access for the micro service to be migrated, and migration of the micro service to be migrated from the source host computer room to the target host computer room is completed. By the processing mode, the target host computer room can provide external data access aiming at the micro service to be migrated after the data synchronization of the source host computer room and the target host computer room is completed, and data conflict caused by the migration of the micro service among a plurality of computer rooms is effectively avoided.
By using the migration method of the microservice in the multiple machine rooms provided by the embodiment, the external data access of each microservice in the multiple machine rooms is effectively managed and controlled through the additionally arranged switch assembly, according to the data migration request aiming at the microservice to be migrated, the external data access of the microservice to be migrated in the source host room is firstly closed through the switch assembly, then probe data is generated, the probe data is written into the data access log of the source host room, the data access log of the source host room is synchronized to the target host room so that the target host room reads the data access log for updating the database, when the target host room reads the probe data, the data synchronization between the source host room and the target host room is completed, the external data access of the microservice to be migrated in the target host room is started through the switch assembly, and therefore, the condition that at most one machine room provides the external data access aiming at the microservice to be migrated at any moment is ensured, and ensuring that the target host computer room provides external data access aiming at the micro service to be migrated after the data synchronization is finished between the source host computer room and the target host computer room, effectively avoiding data conflict caused by the migration of the micro service among a plurality of computer rooms, and optimizing the migration mode of the micro service in the plurality of computer rooms.
Example two
Fig. 2 is a flowchart illustrating a migration method of micro services in multiple machine rooms according to a second embodiment of the present invention, where as shown in fig. 2, the method includes the following steps:
step S201, configuring a master machine room and a slave machine room for each micro service in a configuration center.
And a main machine room and a slave machine room can be configured for each micro-service in the configuration center based on the principles of machine room flow balance and the like. For each micro-service, the master room of the micro-service is used to provide external data access, and in the case that the master room provides external data access, the slave room of the micro-service does not provide external data access, but serves as a hot-standby. Some micro services need to be called each other, for example, a plurality of micro services related to user production content need to be called each other, or a plurality of micro services related to user account assets need to be called each other. If different host rooms are configured for a plurality of micro services with calling relations, in the process of calling the micro services, calling needs to be carried out through a machine room special line or a public network between machine rooms, and then the calling of the micro services is likely to be influenced by unstable factors such as network jitter existing in the machine room special line and the public network.
In order to enable a plurality of micro services having a calling relationship with each other to be called in real time, in the present invention, the plurality of micro services having a calling relationship with each other are configured as the same master room and the same slave room. Specifically, a plurality of micro services with calling relations are divided into the same micro service group to obtain a plurality of micro service groups, different group domain names are configured for each micro service group, and then a main machine room and a slave machine room are configured for each micro service group in a configuration center by taking the micro service group as a unit. By the configuration mode, a plurality of micro services with calling relation can be called in the same machine room, cross-machine-room calling is not needed, and real-time calling among the micro services is effectively realized.
Step S202, according to the data migration request aiming at the micro service to be migrated, determining a source host computer room and a target host computer room corresponding to the micro service to be migrated.
The data migration request can be triggered according to the updated configuration of the micro service to be migrated in the configuration center. For example, when there is traffic imbalance in multiple machine rooms or when a network condition is abnormal in a certain machine room, the configuration of a master machine room and a slave machine room of the microservice to be migrated needs to be updated, and the microservice to be migrated is migrated from the source machine room to the target machine room, then the data migration request may be triggered according to the updated configuration of the microservice to be migrated in the configuration center. In addition, in the configuration center, other machine rooms except the target main machine room in the plurality of machine rooms can be configured as slave machine rooms corresponding to the micro-service to be migrated.
Wherein, the data migration request may include: in step S202, the source host room and the target host room corresponding to the micro service to be migrated may be determined according to the source host room identifier and the target host room identifier in the data migration request, based on the information such as the micro service identifier, the source host room identifier, and the target host room identifier of the micro service to be migrated.
Specifically, the target host computer room corresponding to the micro service to be migrated may be a slave computer room originally corresponding to the micro service to be migrated, or may be a computer room other than the slave computer room instead of the slave computer room. If the target host machine room corresponding to the micro service to be migrated is the slave machine room, since all data of the micro service to be migrated is stored in the slave machine room, data migration for the micro service to be migrated does not need to be performed between the source host machine room and the target host machine room. If the target host computer room corresponding to the micro service to be migrated is not the slave computer room, the target host computer room may not store all the data of the micro service to be migrated, and the data migration between the source host computer room and the target host computer room for the micro service to be migrated needs to be started.
And step S203, utilizing the switch component to close the external data access of the micro service to be migrated in the source host computer room.
The invention adds a switch component, generates configuration information after the configuration center completes the configuration of the host computer room and the slave computer room of each micro-service, and utilizes the switch component to open the external data access of each micro-service in the corresponding host computer room and close the external data access of each micro-service in the corresponding slave computer room according to the configuration information. After the source host computer room corresponding to the micro service to be migrated is determined in step S203, the switch component may be utilized to close the external data access of the micro service to be migrated in the source host computer room, so that the source host computer room may no longer receive the data access request for the micro service to be migrated.
And step S204, generating probe data, writing the probe data into the data access log of the source host computer room, and synchronizing the data access log of the source host computer room to the target host computer room.
In order to effectively identify whether data synchronization is finished between a source host computer room and a target host computer room, probe data is generated according to a preset data generation rule after a switch component is utilized to close external data access of a micro service to be migrated in the source host computer room, wherein the probe data is data without actual operation meaning, for example, the specific content of the generated probe data can be "# # # # # abcde # # # # #". And writing the generated probe data into a data access log of the source host computer room, and synchronizing the data access log of the source host computer room to the target host computer room so that the target host computer room can read the data access log to update the database. In the data access log of the source host computer room, the writing position of the probe data is located after the operation instruction of all data writing operations executed by the source host computer room for the micro service to be migrated, and is used for identifying the end of data synchronization between the source host computer room and the target host computer room.
And S205, reading the data access log by the target host computer room to update the database, and starting external data access of the micro service to be migrated in the target host computer room by using the switch assembly when the probe data is read.
If the target host computer room corresponding to the micro service to be migrated is the slave computer room, the target host computer room can directly read the data access log to update the database; and if the target host computer room corresponding to the micro service to be migrated is not the slave computer room, after the data migration is finished, the target host computer room reads the data access log again to update the database. Specifically, the target host computer room reads the data access log of the source host computer room, and writes the data into the database of the target host computer room by performing data write operation recorded in the data access log, thereby implementing database update. When the target host computer room reads the probe data in the data access log, it is indicated that the target host computer room has completed the execution of all data write-in operations executed by the source host computer room for the micro service to be migrated, that is, data synchronization is completed, then the switch assembly is used to start the external data access of the micro service to be migrated in the target host computer room, so that the target host computer room provides the external data access for the micro service to be migrated, and the migration of the micro service to be migrated from the source host computer room to the target host computer room is completed.
Step S206, receiving a data access request aiming at the micro service to be migrated.
After the switch assembly is used for starting the external data access of the micro-service to be migrated in the target host computer room, the target host computer room can provide the external data access aiming at the micro-service to be migrated. When a user or a business operation and maintenance person and the like want to access data of the micro service to be migrated, a data access request aiming at the micro service to be migrated can be sent, wherein the data access request can carry information such as micro service identification, a request method, request content, a request URL (uniform resource locator), a requested server address and a communication protocol. A data access request for the microservice to be migrated is received in step S206. After receiving the data access request, the data access request is routed to the target host computer room corresponding to the micro service to be migrated according to the configuration information of the configuration center, and the data access request is processed by the target host computer room.
Step S207, if the data access request is a data write request, performing a data write operation to write data into the database of the target host computer room corresponding to the micro service to be migrated, and synchronizing the data write operation to the slave computer room corresponding to the micro service to be migrated, so that the slave computer room performs the data write operation.
The data access request may be a data read request or a data write request. If the data access request is a data reading request, data reading operation is executed to read data from a database of a target host computer room corresponding to the micro service to be migrated; if the data access request is a data write request, performing data write operation to write data into the database of the target host room corresponding to the micro service to be migrated, and updating the data in the database of the target host room by performing the data write operation.
By using the migration method of the micro-services in the multiple machine rooms provided by the embodiment, the configuration center configures the master machine room and the slave machine room for each micro-service, so that the precise configuration of the master machine room and the slave machine room based on the micro-services is realized, and the same master machine room and the same slave machine room are configured for the multiple micro-services with the calling relationship with each other, so that the multiple micro-services with the calling relationship with each other can be called in real time and are not influenced by unstable factors such as network jitter existing in a special line of the machine room and a public network; when the micro-service migration requirement exists, the outward data access of the micro-service to be migrated in the source host room is closed by utilizing the additionally arranged switch assembly, the end of data synchronization between the source host room and the target host room is identified by the probe data written in the data access log of the source host room, and when the probe data is read by the target host room, the outward data access of the micro-service to be migrated in the target host room is opened by utilizing the switch assembly, so that the outward data access aiming at the micro-service to be migrated is provided by the target host room after the data synchronization of the source host room and the target host room is finished, and the data conflict caused by the migration of the micro-service among a plurality of machine rooms is effectively avoided; in addition, unidirectional data synchronization from the main machine room to the auxiliary machine room is realized, and data collision in a multi-machine-room scene is effectively avoided.
