[0047] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a method, device and storage medium for automatically switching traffic in multiple computer rooms.

[0048] See also Figure 1 , Figure 1 A flow chart of an embodiment of a method for automatic switching of multi-machine room traffic provided by the present application, the method comprising:

[0049] Step S101, configuring basic resources for the target business, the basic resources including a business server corresponding to the target business and at least two computer rooms for constructing the business server, and the business server is provided with flow switching configurations of at least two computer rooms;

[0050] Step S102: When traffic interruption occurs in any one of the at least two computer rooms, traffic sent to the first computer room is switched to the second computer room according to the traffic switching configuration, and the first computer room is the computer room where the traffic interruption occurs.

[0051] The method for automatic switching of multi-computer room traffic of the present invention first configures basic resources for the target business, the basic resources include the business server corresponding to the target business, and at least two computer rooms for constructing the business server, and the business server is provided with traffic switching configurations of at least two computer rooms; when traffic interruption occurs in any of the at least two computer rooms, the traffic sent to the first computer room is switched to the second computer room according to the traffic switching configuration, and the first computer room is the computer room where the traffic interruption occurs. The optimization of the network architecture of the present application is based on the hot standby mode of multiple computer rooms, carrying services at the same time, and distributing traffic to multiple computer rooms according to the configuration rules of basic resources, so as to achieve the purpose of high-availability cluster load balancing. When one of the computer rooms fails, the traffic of the failed computer room can be automatically, quickly and timely transferred to other computer rooms to ensure the normal operation of the business.

[0052] In step S101 of some embodiments, basic resources are configured for the target business, and the basic resources include a business server corresponding to the target business, and at least two computer rooms for constructing the business server, and the business server is provided with traffic switching configurations of at least two computer rooms. According to the needs of the target business, an appropriate business server is selected or deployed. The business server is a virtual server that carries the core logic, data processing and other functions of the business. At least two computer rooms are constructed in advance based on factors such as business scale and performance requirements to store business servers and other necessary network equipment. The selection and layout of the computer room should take into account factors such as geographical dispersion, network connection quality and physical security to improve the disaster recovery capability and stability of the overall system. Then, the traffic switching configuration is set in the business server to achieve flexible scheduling of traffic between computer rooms. Through reasonable configuration, it can be ensured that when a computer room fails, the traffic can be quickly and accurately switched to other computer rooms, thereby ensuring the continuity of the business.

[0053] It should be noted that there are two situations in which a computer room is responsible for business. One is that each computer room realizes multiple target businesses at the same time, and the other is that multiple computer rooms realize multiple target businesses at the same time. In the first situation, each computer room is a multi-business computer room, so each multi-business computer room will build multiple business servers according to the number of businesses, and respond to different business requests through multiple business servers to improve business efficiency; in the second situation, multiple computer rooms are single-business computer rooms, and the business server built in each single-business computer room is the same business server, and then respond to the same business request through the same business server, realizing data intercommunication and sharing between multiple computer rooms of the same business, avoiding the problem that one computer room is paralyzed and all computer rooms cannot work. In addition, in occasions with a wide range of businesses, the above two situations may occur at the same time, that is, a computer room can realize multiple different businesses by itself, and can also cooperate with other computer rooms to realize the same business.

[0054] It should also be noted that the traffic switching configuration is a configuration rule for traffic switching in at least two computer rooms, which is constructed based on the load balancing mode combining lvs and nginx. The business server will distribute the traffic of the target business in at least two computer rooms according to the above configuration rules to improve the stability and reliability of the system. Specifically, based on the load balancing working mode of lvs on the TCP / IP four-layer model, the forwarding of the request of the target business is realized, and based on the load balancing working mode of nginx on the OSI seven-layer model, the traffic weight distribution of at least two computer rooms is realized. Among them, lvs, as a high-performance load balancing solution under the Linux operating system, mainly works on the TCP / IP four-layer model. Lvs processes the data packets of the transport layer and distributes them to different business servers, realizes the accurate forwarding of the target business request, effectively balances the load, and avoids the situation of single point overload. This load balancing mode based on the TCP / IP four-layer model is efficient and flexible, can handle a large number of concurrent businesses, and ensures the high availability of the business.

[0055] In order to further improve the flexibility and intelligence of the system, nginx will be introduced as another layer of load balancer. Nginx works on the OSI seven-layer model, so it can perform more detailed traffic management according to the specific content of HTTP requests. By configuring various load balancing algorithms, Nginx can distribute traffic according to the traffic weight ratio between at least two computer rooms, that is, it can dynamically adjust the traffic distribution ratio according to multiple factors such as real-time load, geographical location, network delay, etc. in multiple computer rooms to achieve the best load balancing effect. When a computer room fails or the load is too high, our traffic switching configuration can respond quickly. The linkage mechanism of Lvs and nginx can detect the status changes of the computer room in real time and automatically adjust the traffic distribution strategy. For example, if the server in a computer room goes down or the response time becomes longer, Lvs and nginx can immediately reduce or stop sending requests to the computer room, and instead distribute the traffic to other healthy computer rooms. Flexible and efficient traffic switching and load balancing between multiple computer rooms are realized, providing users with a smoother and more reliable service experience.

[0056] Reference Figure 2 The traffic switching configuration also includes the IP addresses of all computer rooms. The configuration rules for switching traffic to at least two computer rooms may include, but are not limited to, the following:

[0057] Step S201: when the at least two computer rooms include one main computer room and one or more auxiliary computer rooms, the flow weight of the main computer room is set to a first weight, and the flow weight of the auxiliary computer room is set to a second weight, and the first weight is greater than the second weight;

[0058] Step S202, allocating traffic according to the first weight and the second weight to obtain an allocation result;

[0059] Step S203: forwarding the request of the target service according to the allocation result and the IP address.

[0060] In steps S201 to S203 of some embodiments, when at least two computer rooms include one main computer room and more than one auxiliary computer room, the traffic weight of the main computer room is set to the first weight, and the traffic weight of the auxiliary computer room is set to the second weight, and the first weight is greater than the second weight; then the traffic is allocated according to the first weight and the second weight to obtain the allocation result; and the request of the target service is forwarded according to the allocation result and the IP address. According to the processing power, the network environment of the location of the computer room or other higher priority factors, one computer room is selected as the main computer room from at least two computer rooms, and the other computer rooms are selected as auxiliary computer rooms, and the traffic weight of the main computer room is used as the first weight, and the traffic weight of the auxiliary computer room is used as the second weight. Since the main computer room has advantages such as stronger processing power and better network environment, it can undertake more business or an important part of the business, so the first weight is greater than the second weight, so that the traffic allocated to the main computer room is greater than that of the auxiliary computer room.

[0061] After determining the weight of each computer room, the number or proportion of requests that each computer room should receive is calculated based on the weight ratio of the main computer room and the secondary computer room. This process can be dynamic and can be adjusted as factors such as network conditions and computer room load change. Then, based on the allocation results and the corresponding IP address, each business request entering the system is forwarded to the corresponding computer room to ensure that the business traffic can reach the designated computer room correctly and efficiently. In addition, during the forwarding process, the load and network conditions of each computer room will be continuously monitored. If a computer room is overloaded or fails, the load balancer will immediately adjust the traffic distribution strategy to transfer part or all of the traffic to other healthy computer rooms.

[0062] In step S102 of some embodiments, when a flow interruption occurs in any one of at least two computer rooms, the flow sent to the first computer room is switched to the second computer room according to the flow switching configuration, and the first computer room is the computer room where the flow interruption occurs. The flow status of the computer room can be monitored in real time by means of flow monitoring, log analysis, alarm system, etc. Once it is found that the flow of a certain computer room (the first computer room) is abnormally interrupted or greatly reduced, the flow sent to the first computer room is immediately switched to the second computer room according to the flow switching configuration in step S101, and the fault detection mechanism is triggered. The flow interruption in the first computer room means that the first computer room can no longer transmit data at this time and can no longer communicate with the data control center or other computer rooms. Therefore, the subsequent flow originally to be sent to the first computer room must be switched to the second computer room. The switching process should be as fast and smooth as possible to reduce the impact on the business. At the same time, after the switch, it should be ensured that the second computer room can carry the switched flow and maintain the normal operation of the business. In addition, after the traffic switching is completed, the fault of the first computer room can be immediately checked and handled: take appropriate repair measures according to the cause of the fault, such as restarting the equipment, repairing network faults, updating software, etc. After the fault handling is completed, the first computer room can also be restored to ensure that it can be reconnected to the system and work normally.

[0063] It should be noted that before switching the traffic sent to the first computer room to the second computer room according to the traffic switching configuration, it should also be determined whether there is the most suitable second computer room to receive the traffic that should have been sent to the first computer room. The judgment is based on, for example, the resource usage ratio. Specifically, the computer room with the lowest current resource usage ratio among at least two computer rooms is obtained, and the computer room with the lowest current resource usage ratio is the second computer room. The lowest resource usage ratio means that the computer room has the most idle space among all computer rooms. Sending the traffic that should have been sent to the first computer room to the second computer room with the most idle space can maximize the efficiency and quality of responding to the target business.

[0064] Reference Figure 3 The steps for determining whether a flow interruption occurs in any one of at least two computer rooms may specifically include, but are not limited to, the following:

[0065] Step S301, sending access requests to at least two computer rooms;

[0066] Step S302: If no feedback is received from all the computer rooms in the at least two computer rooms, the corresponding computer room in the at least two computer rooms that has no feedback is obtained, and the feedback is information of responding to the access request and attaching a return value;

[0067] Step S303: determine that the corresponding computer room is the computer room where traffic interruption occurs.

[0068] In steps S301 to S303 of some embodiments, an access request is first sent to at least two computer rooms; if no feedback is received from all computer rooms in at least two computer rooms, the corresponding computer room without feedback in at least two computer rooms is obtained, and the feedback is information of responding to the access request and attaching a return value; then the corresponding computer room is determined to be the computer room where the traffic interruption occurs. In order to monitor the online status and response capability of each computer room in real time, by sending an access request and obtaining corresponding feedback, it is determined whether each computer room can normally receive and respond to the target service. After sending the access request to at least two computer rooms, wait to receive feedback from each computer room. At the same time, a timeout period can be pre-set for waiting for feedback from the computer room. If no feedback is received from a certain computer room within the timeout period, it is considered that the computer room has no response, and the information of the computer room that has not responded is recorded, and the computer room information may include the IP address of the computer room or the target service it is responsible for. Based on the information of the computer rooms that have not responded, these computer rooms are marked as "computer rooms where the traffic interruption occurs". Further measures can be taken based on the computer room information of all computer rooms, such as starting a backup computer room, etc. At the same time, error messages can be sent to the client to notify the staff, thereby ensuring service continuity and data availability.
