In the following description, the terms "first" and "second" are used for descriptive purposes only and are not intended to indicate or imply relative importance. The following description provides embodiments of the present application, where different embodiments may be substituted or combined, and thus the present application is intended to include all possible combinations of the same and/or different embodiments described. Thus, if one embodiment includes feature A, B, C and another embodiment includes feature B, D, then this application should also be considered to include an embodiment that includes one or more of all other possible combinations of A, B, C, D, even though this embodiment may not be explicitly recited in text below.

Furthermore, features described with respect to some examples may be combined into other examples.
It should be noted that, in a distributed system, the message middleware is widely used to exchange data between systems, which facilitates asynchronous decoupling. There are now many open source message middleware, and the middleware testing group has three common message products, kafka, RabbitMQ, and rocktmq. Wherein kafka is a LinkedIn open-source distributed publish-subscribe message system, which currently belongs to Apache top level project. kafka is primarily characterized by Pull-based patterns for handling message consumption, pursuing high throughput, initially for log collection and transmission. The version 0.8 starts to support copying, does not support transaction, has no strict requirements on message repetition, loss and error, and is suitable for data collection service of internet service generating a large amount of data. The RabbitMQ is an open source message queue system developed by Erlang language and is realized based on an AMQP protocol. The main features of AMQP are message oriented, queue, routing (including point-to-point and publish/subscribe), reliability, security. The AMQP protocol is more used in enterprise systems, and has high requirements on data consistency, stability and reliability, and the requirements on performance and throughput are further. The RocktMQ is a message middleware of an Ali open source, is developed by pure Java, has the characteristics of high throughput and high availability, and is suitable for large-scale distributed system application. The rocktmq idea originates from Kafka, but is not a Copy of Kafka, optimizes reliable transmission and transaction of messages, and is widely applied to scenes such as transaction, recharge, stream calculation, message push, log streaming processing, and bindlog distribution in the ali group at present.
In the examples of the present application, kafka will be taken as an example to explain the scheme of the present application.
It should also be noted that kafka is a message system based on publish and subscribe. It is commonly referred to as a "distributed commit log" or "distributed streaming platform". It is characterized by the ability to provide high throughput for both distribution and subscription. kafka can produce about 25 thousand messages per second (50MB) and process 55 thousand messages per second (110 MB). Whereas kafka generally consists of three parts: the kafka cluster comprises a kafka producer (producer, i.e. a generator of a message), a kafka cluster and a kafka consumer (consumer, i.e. a consumer of the message), wherein the kafka producer is responsible for writing the message into the kafka cluster, one or more brokers (i.e. caching agents) are contained in the kafka cluster, and one or more servers in the kafka cluster are collectively called a borker), and the kafka consumer is responsible for reading the message written in the kafka cluster and consuming the message.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a computer room disaster recovery processing system according to an embodiment of the present disclosure.
As shown in fig. 1, the computer room disaster recovery processing system may include a first computer room 10, a second computer room 20, and a management terminal 30, where the first computer room 10 includes a first server 101, a first cluster 102, and a first user terminal 103, and the second computer room includes a second server 201, a second cluster 202, and a second user terminal 203. The first machine room 10 and the second machine room 20 may be two machine rooms set up at different geographical locations.
A cluster may have multiple kafka servers, and a kafka server may be regarded as a brooker, i.e., the first cluster 102 and the second cluster 202 may be a server group integrating multiple kafka servers.
The first server 101 and the second server 201 are message producers, and are kafka producer terminals that send messages to brokers in the cluster, and specifically may be servers or clients on which kafka producer clients are installed.
The first user terminal 103 and the second user terminal 203 are message consumers, and are kafka consumer terminals that read messages from brokers in the cluster, and may specifically be servers or clients that are equipped with kafka consumer clients.
The management terminal 30 is responsible for managing and controlling the entire kafka message transmission process, and may send instructions to the first server 101, the first cluster 102, the first user terminal 103, the second server 201, the second cluster 202, and the second user terminal 203 through the communication link, respectively, so as to change, for example, sending a message object to the second server 201 and reading the message object by the second user terminal 203, where the management terminal 30 may specifically be a server terminal loaded with kafka management system software.
It should be noted that, one or more first servers 101, second servers 201, first user terminals 103, and second user terminals 203 may be provided, the number of servers and user terminals in the computer room disaster recovery processing system shown in fig. 1 is only an example, and in a specific reality, the computer room disaster recovery processing system may include any number of first servers 101, second servers 201, first user terminals 103, and second user terminals 203, which is not limited in this application.
Illustratively, when a teacher wants to send a red packet to students in a class group, the teacher sends a red packet sending request to the first server 101 through the mobile phone terminal of the teacher, and the first server 101 generates red packet information according to the red packet sending request and writes the red packet information into the first cluster 102. After reading the red envelope information from the first cluster 102, the first user terminal 103 consumes the red envelope information, so that the red envelope information is sent to the mobile phone terminals of students, and the red envelope information is sent. When the first server 101 fails, the management terminal 30 sends an instruction to the second server 201, so that the second server 201 replaces the first server 101 to receive the red packet request sent by the teacher's mobile phone terminal and write red packet information into the first cluster 102. When the first user terminal 103 fails, the management terminal 30 sends an instruction to the second user terminal 203, so that the second user terminal 203 replaces the first user terminal 103 to read the red packet information in the first cluster 102 and consume the red packet information, and the red packet information is sent to the mobile phone terminals of students.
Next, a computer room disaster recovery processing method provided in an embodiment of the present application is described with reference to a computer room disaster recovery processing system shown in fig. 1.
Referring to fig. 2, fig. 2 is a schematic flowchart of a method for processing a computer room disaster tolerance according to an embodiment of the present application. In an embodiment of the present application, the method includes:
s201, when a first machine room fault is detected, determining a terminal with the fault in the first machine room as a target terminal; the target terminal is used for processing the message in the first cluster of the first computer room.
In the embodiment of the present application, the execution subject of the present application may be a management terminal. When the management terminal detects a failure of the first machine room, the management terminal first determines what the specific failed terminal is in the first machine room and determines it as a target terminal. The target terminal may be a server in the first room for writing messages to the first cluster or may be a user terminal in the first room for reading messages from the first cluster.
S202, sending a disaster tolerance instruction to the target terminal of the second machine room; the disaster recovery instruction is used for instructing the target terminal of the second computer room to process the message of the first cluster.
In the embodiment of the application, after determining the target terminal with the fault in the first machine room, the management terminal sends the disaster recovery instruction to the target terminal in the second machine room, so that the target terminal in the second machine room replaces the target terminal in the first machine room to write or read the message to or from the first cluster after receiving the disaster recovery instruction.
In this embodiment of the application, the target terminal with a fault in the first machine room may have the following:
the first condition is as follows: the target terminal with the fault in the first machine room is the server of the first machine room, which means that the server of the first machine room has the fault and cannot generate a new message to be written into the first cluster. The management terminal sends a disaster tolerance instruction to the server of the second machine room, and the server of the second machine room starts and replaces the server of the first machine room to produce and send the message to the first cluster after receiving the disaster tolerance instruction.
Case two: the target terminal with the fault in the first machine room is the user terminal of the first machine room, which means that the user terminal of the first machine room has the fault and cannot read a new message from the first cluster. The management terminal sends a disaster tolerance instruction to the user terminal of the second machine room, and the user terminal of the second machine room starts and replaces the user terminal of the first machine room to read the message of the first cluster and consume the message after receiving the disaster tolerance instruction.
In one embodiment, the first cluster includes at least two partitions, each located in a different geographic location.
In the embodiment of the application, the first cluster is provided with at least two partitions, and the kafkabroks in the first cluster can be deployed into all available partitions on average. The partitions can be arranged in different areas, namely, the partitions can be equivalently arranged in a plurality of different machine rooms. This ensures that there is no impact on the availability of kafka when a single available partition of the cluster fails.
It is possible that the available partitions of the first room and the second room may be different, for example: the first cluster of the first machine room is provided with 3 available partitions, and the second cluster of the second machine room is provided with 2 available partitions.
It is possible that the leader (the "master" copy of multiple copies per partition, the object for which the producer sends data preferentially, and the object for which the consumer consumes data preferentially) and the copy of kafka may be located in different partitions, thereby ensuring that a partition failure will not affect the message consumption of the kafka consumer, i.e., the user terminal.
In one possible implementation, step S201 further includes:
recording partition position information of the first cluster;
when the partition fault of the first cluster is detected, acquiring the partition position information corresponding to the fault partition;
and generating and sending warning information to a preset manager terminal based on the partition position information.
In this embodiment of the present application, because the partitions of the first cluster are set in different regions, the management terminal first records the partition location information of all the partitions, and when it detects that a partition in the first cluster fails, the management terminal obtains the previously recorded partition location information corresponding to the partition. The management terminal generates warning information based on the partition position information and sends the warning information to a preset manager terminal. The administrator terminal may be a terminal used by an administrator of the first cluster that is set in advance. The warning message may be a text message or a voice message containing the content "the first cluster partition located in xx region fails, please go to view".
In one possible implementation, step S202 is followed by:
when the target terminal of the first machine room is detected to be repaired, sending a reset instruction to the target terminal of the second machine room; the reset instruction is used for instructing the target terminal of the second machine room to stop processing the message to the first cluster.
In the embodiment of the application, only the first machine room is opened to be used as the main machine room at ordinary times, the second machine room is temporarily closed, and the first machine room is used when disaster recovery is performed. Therefore, after the fault of the target terminal in the first machine room is repaired, the target terminal in the second machine room needs to be switched back to the target terminal in the first machine room to continue to process the message of the first cluster. And after detecting that the target terminal of the first machine room is repaired, the management terminal sends a reset instruction to the target terminal of the second machine room to enable the target terminal of the second machine room to stop processing the message of the first cluster.
Possibly, the management terminal sends a seventh instruction to the target terminal of the first room, where the seventh instruction is used to instruct the target terminal of the first room to restart processing the message of the first cluster.
Through the steps, when the management terminal detects the fault of the first machine room, the management terminal determines the target terminal with the fault in the first machine room. Because the second machine room is also provided with the target terminal, the management terminal can send the disaster recovery instruction to the target terminal in the second machine room after determining the target terminal, so that the target terminal in the second machine room replaces the target terminal in the first machine room to continue to process the message of the first cluster in the first machine room, thereby ensuring that the kafka service is not affected when the first machine room is in fault, and avoiding the situation that the overstocked message of the fault machine room cannot be consumed in time due to the switching of the whole machine room in disaster recovery.
Referring to fig. 3, fig. 3 is a schematic flow chart of another computer room disaster recovery processing method provided in the embodiment of the present application. As shown in fig. 3, the method includes:
s301, when the first machine room is detected to be in fault, determining that the terminal with the fault in the first machine room is a target terminal.
The detailed process is as described in step S201, and therefore, is not described herein again.
S302, sending a first instruction to the server of the second machine room; the first instruction is used for instructing the server of the second machine room to start and configure first configuration information of the server of the first machine room; the first configuration information is configuration information required by the server of the second computer room to write a message to the first cluster.
In the embodiment of the application, the target terminal with the fault in the first machine room is a server. The management terminal sends a first instruction to the server of the second machine room, the server of the second machine room is in a closed state in an initial state, and after receiving the first instruction, the management terminal is switched to an open state and configures first configuration information of the server of the first machine room. Since the message themes (e.g., red envelope themes) handled by different clusters are different, the servers of the second room need to be configured with the same configuration as the servers of the first room to be able to write the message of the theme.
S303, after the server of the second machine room is started, sending a second instruction to the server of the second machine room; the second instruction is used for instructing the server of the second computer room to write a message to the first cluster.
In the embodiment of the application, after the server in the second machine room is started and the configuration information of the related theme is configured, the management terminal sends the second instruction to the server in the second machine room. And after receiving the second instruction, the server in the second machine room associates with the first cluster and starts to take over the server in the first machine room to produce and write a new message into the first cluster.
Through the steps, when the management terminal detects the fault of the first machine room, the management terminal determines the target terminal with the fault in the first machine room. Because the second machine room is also provided with the target terminal, the management terminal can send the first instruction to the server in the second machine room after determining that the target terminal is the server, so that the server in the second machine room replaces the server in the first machine room to continue to write the message into the first cluster in the first machine room, the fact that the kafka service is used in the business when the first machine room breaks down is guaranteed, and the situation that the overstocked message of the fault machine room cannot be consumed in time due to the switching of the whole machine room during disaster tolerance is avoided.
Referring to fig. 4, fig. 4 is a schematic flowchart of another computer room disaster recovery processing method provided in the embodiment of the present application. As shown in fig. 4, the method includes:
s401, when a first machine room fault is detected, determining a terminal with the fault in the first machine room as a target terminal; the target terminal is used for processing the message in the first cluster of the first computer room.
The detailed process is shown in step S201, and therefore, is not described herein again.
S402, sending a third instruction to the user terminal of the second machine room; the third instruction is used for instructing the user terminal of the second machine room to start and configuring second configuration information of the user terminal of the first machine room; the second configuration information is configuration information required by the user terminal of the second machine room to read a message from the first cluster.
In the embodiment of the application, the target terminal with the fault in the first machine room is the user terminal. The management terminal sends a third instruction to the user terminal of the second machine room, the user terminal of the second machine room is in a closed state in the initial state, and after receiving the third instruction, the management terminal is switched to an open state and configures second configuration information of the user terminal of the first machine room. Since the message themes (e.g. red envelope themes) handled by different clusters are different, the user terminal of the second room needs to be configured with the same configuration as the user terminal of the first room to be able to read the message of the theme.
S403, after the user terminal of the second machine room is started, sending a fourth instruction to the user terminal of the second machine room; the fourth instruction is configured to instruct the user terminal of the second equipment room to read a message to the first cluster.
In this embodiment of the application, after the user terminal in the second machine room starts and configures the configuration information of the related theme, the management terminal sends the fourth instruction to the user terminal in the second machine room. And after receiving the fourth instruction, the user terminal of the second computer room associates with the first cluster and starts to take over the user terminal of the first computer room to read and consume the message of the first cluster.
S404, detecting whether the server of the first machine room is in fault.
In the embodiment of the application, after the management terminal determines that the target terminal is the user terminal, the management terminal also detects whether the server of the first machine room has the same fault.
S405, when the server of the first machine room fails, sending a fifth instruction to the server of the second machine room; the fifth instruction is used for instructing the server of the second computer room to start and write a message to a second cluster of the second computer room.
In this embodiment of the application, if the server in the first machine room also fails, the management terminal sends a fifth instruction to the server in the second machine room. And after receiving the fifth instruction, the server of the second machine room is switched to the open state and writes the message into the second cluster of the second machine room.
S406, after the server of the second machine room is started, sending a sixth instruction to the user terminal of the second machine room; the sixth instruction is configured to instruct the user terminal in the second equipment room to read a message to the first cluster and the second cluster at the same time.
In the embodiment of the application, because both the server and the user terminal of the first machine room have faults, and the user terminal of the second machine room is already reading the overstocked message in the first cluster, if the server of the second machine room writes the message to the first cluster, the newly produced message is written into the first cluster across the machine room and then read back across the machine room, so that the efficiency is low and the resources are occupied. Therefore, the newly produced message is directly written into the second cluster, and the management terminal sends a sixth instruction to the user terminal of the second machine room, so that the user terminal of the second machine room can simultaneously read the messages of the first cluster and the second cluster, thereby ensuring the consumption efficiency of the new message and processing the overstocked first cluster message.
Through the steps, when the management terminal detects the fault of the first machine room, the management terminal determines the target terminal with the fault in the first machine room. Because the second machine room is also provided with the target terminal, the management terminal can send the disaster recovery instruction to the target terminal in the second machine room after determining the target terminal, so that the target terminal in the second machine room replaces the target terminal in the first machine room to continue to process the message of the first cluster in the first machine room, thereby ensuring that the kafka service is not affected when the first machine room is in fault, and avoiding the situation that the overstocked message of the fault machine room cannot be consumed in time due to the switching of the whole machine room in disaster recovery. If the server and the user terminal of the first machine room are detected to be in fault, the user terminal of the second machine room reads the overstocked message of the first cluster, and simultaneously, the server of the second machine room directly writes the newly generated message into the second cluster, so that the message consumption efficiency is ensured, and the excessive occupation of resources is reduced.
