FIG. 1 illustrates a flow diagram of an information processing method applied to a distributed system having a plurality of service nodes, according to some embodiments of the invention. Referring to fig. 1, the information processing method includes the steps of:
step S110, obtaining a connection information table containing connection information of the plurality of service nodes and the main control node in the distributed system;
step S120, receiving heartbeat information sent to the master control node by each service node in the plurality of service nodes;
step S130, judging whether the connection between the service node and the main control node is failed or not based on the heartbeat information;
step S140, if it is determined that the connection fails, deleting the connection information of the service node from the connection information table.
According to the information processing method in the example embodiment of fig. 1, on one hand, a connection information table containing connection information between a service node and a master node is obtained, so that connection information of available service nodes can be obtained; on the other hand, whether the connection fails is judged based on the heartbeat information sent by the service node to the main control node, and the connection information of the service node is deleted from the connection information table when the connection fails, so that the unavailable service node can be automatically shielded, and the service availability of each service node of the distributed system can be ensured.
Next, the information processing method in the exemplary embodiment of fig. 1 will be described in detail.
In step S110, a connection information table including connection information between the plurality of service nodes and the master node in the distributed system is obtained.
The information processing method in the example of fig. 1 may be applied to a server of a distributed system having a plurality of service nodes, each of which stores a static resource and a dynamic resource corresponding to a service provided by the distributed system. For example, when the service provided by the distributed system is a commodity sales service, information such as website page information, commodity information, order information, and the like may be stored in each service node. In addition, each service node has a function of independently interacting data with the outside, each service node can monitor the heartbeat signal, and when one service node monitors that the heartbeat signal cannot be kept, the other service node is driven to load corresponding data onto the other service node.
Further, the distributed system may further include a master control node, where the master control node is a node that controls the plurality of service nodes, and the master control node may receive monitoring data sent by each service node, and when the monitoring data of a service node indicates that the heartbeat signal of the service node cannot be maintained, drive the service node to load corresponding data thereon to another service node. In some embodiments, the server may act as a master node for a distributed system. The connection information of the service node and the master node of the distributed system may include: IP (Internet Protocol) address information of the service node, port name information, and the like.
In some embodiments, connection information of a plurality of service nodes and a master node in the distributed system may be obtained, and a connection information table may be established based on the connection information of each service node and the master node. Further, the connection information table, i.e. the contact information between each service node and the master node, may be refreshed at predetermined time intervals.
It should be noted that the predetermined time interval may be set according to the number of service nodes in the distributed system and the number of currently available service nodes, for example, a connection information table may be refreshed every 5 minutes, before the refreshing, the a1, a2, and A3 service nodes are connected to the master node, the connection information table includes connection information of the a1, a2, and A3 service nodes, and after the refreshing, the a2 service node is dropped, that is, connection information of the a2 service node cannot be obtained, the connection information table includes connection information of the a1 and A3 service nodes.
In step S120, heartbeat information sent by each service node of the plurality of service nodes to the master node is received.
In some embodiments, each service node in the distributed system sends heartbeat information to the master control node at regular time, where the heartbeat information is a self-defined information field that informs the other side of its own state at regular time between the sending end and the receiving end, and the heartbeat information may be sent at a certain time interval, for example, 1 s. The heartbeat information can be used to determine whether the connection between the service node and the master node has failed.
Step S130, judging whether the connection between the service node and the main control node is failed or not based on the heartbeat information.
In some embodiments, if the master node does not receive the heartbeat information within a predetermined time, for example, 1s, a count of reception failures is performed, and if the count of reception failures reaches a predetermined value, it is determined that the connection between the service node and the master node has failed. For example, when the master node cannot receive the heartbeat information of the a2 service node 3 times in succession, it is determined that the connection between the a2 service node and the master node has failed.
Step S140, if it is determined that the connection fails, deleting the connection information of the service node from the connection information table.
In some embodiments, when it is determined that the connection between the service node and the master node fails, the connection information of the service node may be deleted from the connection information table, and after the service node is deleted, other service nodes may not be able to call the deleted service node. For example, when it is determined that the connection between the a2 service node and the master node is failed, the connection information of the a2 service node is deleted from the connection information table, and the remaining service nodes cannot retrieve the connection information of the a2 service node.
In addition, in some embodiments, when the connection between the service node and the master node fails, before the connection information of the service node is removed from the connection information table, another service node connected to the service node in the connection information table may be determined, and data on the service node is loaded to the another service node. By loading the data node on the failed service node onto another service node that is available, the availability of the services of the entire distributed system can be guaranteed.
Further, in some embodiments, after refreshing the connection information table, the refreshed connection information table is sent to each serving node in the connection information table. For example, at the current time, it is detected that a1, A3, B1, and B2 service nodes in the distributed system are connected to the master node, and after connection information between a1, A3, B1, and B2 service nodes and the master node is acquired, the connection information is collected and sorted into a connection information list, and the connection information list is sent to a1, A3, B1, and B2 service nodes, respectively, and after a predetermined time elapses, the connection information list is refreshed, and is sent to a1, A3, B1, and B2 service nodes, respectively, so as to ensure that the a1, A3, B1, and B2 service nodes can receive the latest connection information. When the B1 service node calls the data of the a1 service node, it knows that the a1 service node is available according to the connection information, and calls the data of the a1 service node according to the predetermined routing rule.
Fig. 2 illustrates a flow diagram for determining whether a connection of a serving node with a master node has failed in accordance with some embodiments of the invention.
Referring to fig. 2, in step S210, confirmation information returned by the master node to the service node in response to the heartbeat information is obtained.
In an example embodiment, when receiving heartbeat information sent by a service node, a master control node sends acknowledgement information to the corresponding service node in response to the heartbeat information, wherein the acknowledgement information indicates that the heartbeat information of the corresponding service node has been received.
In step S220, it is determined whether a difference between the number of times of the heartbeat information and the number of times of the confirmation information is greater than a first predetermined value.
In an example embodiment, whether the connection between the service node and the main control node fails may be determined by comparing the number of the heartbeat information sent by the service node with the number of the acknowledgement information returned by the main control node. For example, when the first predetermined value is 3 and the service node sends 10 times of heartbeat information, the main control node only returns 6 times of confirmation information, and the difference between the number of times of heartbeat information sent by the service node and the number of times of confirmation information returned by the main control node is 4, which is greater than the first predetermined value 3.
In step S230, if it is determined that the connection between the service node and the main control node is greater than the first predetermined value, it is determined that the connection between the service node and the main control node fails.
And if the difference between the number of times of the heartbeat information sent by the service node and the number of times of the confirmation information returned by the main control node is larger than a first preset value, determining that the connection between the service node and the main control node fails.
It should be noted that the first predetermined value is set according to the number of service nodes in the distributed system and the number of currently available service nodes, and when the number of service nodes in the distributed system and the number of currently available service nodes are large, the first predetermined value may be set to be large, for example, 5 times.
Fig. 3 illustrates a flow diagram for determining whether a master node has failed in accordance with some embodiments of the invention.
Referring to fig. 3, in step S310, communication detection information is sent to each of the plurality of service nodes through the master node. For example, the master node may send the communication detection information to all the service nodes, and count the total number of times of sending the communication detection information.
In step S320, detection confirmation information returned by each service node in response to the communication detection information received by the master node is obtained. In an example embodiment, the service node sends heartbeat information, i.e. detection confirmation information, to the master node according to the received communication detection information. Further, the total number of times of heartbeat information received by the master node may be counted.
In step S330, it is determined whether the master node fails based on a ratio of the total number of times of the detection confirmation information and the total number of times of the communication detection information.
The ratio of the total number of times of communication detection information to the total number of times of detection confirmation information in a predetermined time may be calculated, and it is determined whether the ratio is smaller than a second predetermined value, where the second predetermined value may be set according to the number of service nodes in the distributed system and the processing capability of the master node. And if the ratio is smaller than the second preset value, determining that the main control node fails.
For example, if the second predetermined value is 80%, the master node receives a piece of corresponding heartbeat information after sending the communication detection information once, and determines that the communication is successful, and if the master node does not receive a piece of corresponding heartbeat information after sending the communication detection information once, the communication is failed. If the master control node accumulatively sends 100 pieces of communication detection information to all the service nodes within 15 minutes, only 50 pieces of heartbeat information are received, the successful receiving proportion is 50 percent and is less than the preset communication success proportion 80 percent, and the master control node is in a fault state at the moment.
Furthermore, in an embodiment of the present invention, an information processing apparatus is also provided. Referring to fig. 4, the information processing apparatus 400 is applied to a distributed system having a plurality of service nodes, and the information processing apparatus 400 may include: an acquisition unit 410, a receiving unit 420, a judging unit 430 and a removing unit 440.
