Referring to fig. 1, fig. 1 is a schematic application scenario diagram of a configuration updating method of a proxy server according to an embodiment of the present application. The configuration updating method of the proxy server is applied to a Redis high availability system in FIG. 1, wherein the Redis high availability system comprises a Redis cluster, a proxy cluster, a monitoring component and a configuration center, the proxy cluster comprises at least one proxy server, and a configuration updating component is arranged in each proxy server, wherein the components of the Redis high availability system in the embodiment are as follows:
configuration center: the configuration center is used for storing the master node information of each master node in the Redis cluster, and the configuration center can be realized through a zookeeper.
Redis cluster: the method comprises the steps that at least one master node is included, each master node is provided with at least one slave node (master-slave architecture) in order to ensure high availability of the Redis cluster, and during operation of the Redis cluster, each slave node starts a master-slave mode, namely each slave node copies data of the corresponding master node, so that data consistency between the slave nodes and the master nodes is ensured as much as possible.
Agent cluster: the proxy server is used for receiving a request of a client and forwarding the request to a Redis cluster of a back end, the proxy server can be Twompproxy, the proxy servers work simultaneously, the proxy servers are isomorphic proxy servers, namely the configuration of the proxy servers is the same, in the embodiment, since the proxy servers have no automatic update function and messages are not exchanged, in order to realize automatic update of the configuration of the proxy servers and maintain consistency of the configuration of the proxy servers, in the embodiment, a configuration update component (Agent) is respectively arranged for each proxy server, each configuration update component detects configuration information (main node information of each main node in the Redis cluster) in real time, and when the configuration information is detected to be updated, the proxy server pulls up the latest configuration and modifies the configuration of the corresponding proxy server.
And (3) a monitoring component: the monitoring module is used for monitoring whether nodes in the Redis cluster are faulty or not, and when an abnormal master node is monitored, the standby slave node of the master node is automatically lifted to be a new master node, and master node information corresponding to the target master node in a configuration center is updated to be master node information of the new master node.
Fig. 2 is a flowchart of a configuration updating method of a proxy server according to an embodiment of the present application. The method is applied to the Redis high availability system shown in FIG. 1, and as shown in FIG. 2, the method includes the following steps S110-S130.
S110, the monitoring component monitors whether a target main node in the Redis cluster is a target abnormal node.
The Redis cluster in this embodiment includes at least one target master node, and the monitoring component needs to monitor each target master node in the Redis cluster, that is, for each target master node, the configuration updating method of the proxy server in this embodiment is used to ensure high availability of nodes in the Redis cluster.
In some embodiments, the monitoring component in this embodiment includes a plurality of sub-monitoring components, and in order to ensure accuracy of the monitoring result, in this embodiment, it is required to determine whether the target host node is an abnormal node in combination with the monitoring result of each sub-monitoring component, specifically, determine whether the target host node is an abnormal node by:
When a target sub-monitoring component in the sub-monitoring components monitors that the target main node is an abnormal node, the target sub-monitoring component acquires monitoring results of other sub-monitoring components aiming at the target main node, wherein the other sub-monitoring components are the sub-monitoring components except the target sub-monitoring component in the sub-monitoring components; and the target sub-monitoring component determines whether the target main node is a target abnormal node according to each monitoring result.
In this embodiment, when the target sub-monitoring component monitors that the target main node is an abnormal node, the monitoring result of other sub-monitoring components on the target main node needs to be queried, where the monitoring result includes an abnormal result and a normal result, the abnormal result indicates that the target main node is an abnormal node, and the normal result indicates that the target main node is a normal node.
That is, when the target sub-monitoring component monitors that the target main node is an abnormal node, the monitoring results of other sub-monitoring components on the target main node are also required to be queried, and whether the target main node is the target abnormal node is determined by combining the monitoring results of other sub-monitoring components.
In some embodiments, the target sub-monitoring component monitors the target master node as an abnormal node by: the target sub-monitoring component sends a detection instruction to the target main node according to a preset time interval; and if the target sub-monitoring component does not receive the feedback instruction returned by the target main node based on the detection instruction within the preset time, the target sub-monitoring component determines that the target main node is an abnormal node.
Specifically, in this embodiment, the preset time interval may be 1s, the preset duration may be 2s, and specific time between the preset time interval and the preset duration may be set as required, which is not limited herein.
When the target master node is judged as an abnormal node, the judgment is subjective judgment, that is, whether the target master node is truly abnormal is not determined yet, and when the target master node is judged as a target abnormal node, the judgment is objective judgment, and at this time, the monitoring component determines that the target master node is abnormal.
Further, the target sub-monitoring component determines whether the target main node is a target abnormal node according to each monitoring result, including: the target sub-monitoring component determines the number of results that the monitoring result is an abnormal result; if the number of the results is greater than or equal to a target threshold, the target sub-monitoring component determines that the target main node is the target abnormal node, and the target threshold is determined according to the number of the sub-monitoring components; and if the number of the results is smaller than the target threshold, the target sub-monitoring component determines that the target main node is not the target abnormal node.
For example, when the number of the sub-monitoring components is N, N is an integer greater than 1, at this time, the target threshold is N/2 (rounded down), at this time, when N is 5, the target threshold is 2, the number of other sub-monitoring components is 4, the corresponding monitoring results are also 4, if 2 or more monitoring results are abnormal results, at this time, the target sub-monitoring components can determine that the target main node is the target abnormal node, or else, determine that the target main node is not the target abnormal node.
The target master node abnormality in this embodiment includes a target master node downtime.
And S120, when the monitoring component monitors that the target main node is a target abnormal node, the monitoring component switches a target slave node corresponding to the target main node in the Redis cluster into a new main node and updates main node information corresponding to the target main node in the configuration center into main node information of the new main node.
In this embodiment, when the monitoring component monitors that the target master node is a target abnormal node, the monitoring component further switches a target slave node corresponding to the target master node to a new master node, specifically, the switching process is that the target slave node is notified to be the new master node, at this time, the target slave node is used as the master node to receive a request forwarded by the proxy server, and other slave nodes of the target master node are notified to perform master-slave replication on the new master node.
In addition, the monitoring component needs to update the master node information corresponding to the target master node in the configuration center to the master node information of the new master node through a publish/subscribe function.
Because the monitoring component includes a plurality of sub-monitoring components, in this embodiment, master-slave switching operation of the target master node needs to be implemented by one sub-monitoring component of the plurality of sub-monitoring components, and at this time, the monitoring component switches a target slave node corresponding to the target master node in the dis cluster to a new master node, including: the monitoring component determines a collar sub-monitoring component from a plurality of sub-monitoring components in an election mode; the head sub-monitoring component determines a target slave node from a slave node set corresponding to the target master node; the lead monitoring component switches the target slave node to the new master node.
Specifically, the election mode includes: each sub-monitoring component finding that the target slave node is abnormal can initiate a voting request to other sub-monitoring components, hope that the other sub-monitoring components cast a vote, and other sub-monitoring components can cast a vote only, generally, cast the sub-monitoring component corresponding to the voting request received first, and after the voting is finished, the monitoring component determines the sub-monitoring component with the highest vote as the leading sub-monitoring component.
In this embodiment, the target master node corresponds to a slave node set, where the slave node set includes at least one slave node, and when performing master-slave switching, the monitoring component first needs to determine the target slave node from the slave node set, and specifically may determine the target slave node by the following two ways:
first kind: the head sub-monitoring component acquires the data synchronization quantity of each slave node in the slave node set and the target master node; and the head sub-monitoring component takes the slave node with the largest data synchronization as the target slave node.
In this embodiment, the target slave node is determined according to the data synchronization amount of each slave node, where the data synchronization amount indicates the data synchronization degree with the target master node, and the larger the data synchronization amount is, the higher the data synchronization degree with the target master node is, and in order to reduce the loss amount of data, the embodiment preferably selects the slave node with the higher synchronization degree as the target slave node.
Second kind: the head sub-monitoring component obtains the priority of each slave node in the slave node set; the lead sub-monitoring component takes the slave node with the highest priority as the target slave node.
In this embodiment, the slave nodes are preferentially determined according to the priority of each slave node, where the priority is determined according to the performance of the corresponding slave node, and the higher the performance of the corresponding slave node is, the higher the corresponding priority is, and in order to increase the processing speed of the data by the node, the embodiment preferentially selects the slave node with the highest priority as the target slave node.
And S130, aiming at each configuration updating component, the configuration updating component monitors the configuration center in real time, and updates the corresponding master node configuration of the proxy server according to the master node information in the configuration center when the update of the master node information in the configuration center is monitored.
In this embodiment, a configuration update component is provided for each proxy server, and each configuration update component monitors a configuration center in real time, and updates the corresponding configuration of a master node of the proxy server according to the master node information in the configuration center when it is detected that the master node information in the configuration center is updated.
Specifically, the configuration updating component in this example determines whether the configuration center has an update by detecting whether the master node information of the configuration center is consistent with the master node information of the local proxy server, if not, it indicates that the configuration center has an update, otherwise, it indicates that the configuration center has no update.
When the fact that the configuration center is inconsistent with the master node information of the local proxy server is detected, the configuration updating component pulls the latest configuration (each master node information) from the configuration center to modify the configuration of the corresponding proxy server, and high-availability switching is achieved.
In summary, the configuration updating method of the seed proxy server provided in the present embodiment is applied to a Redis high availability system, where the Redis high availability system includes a Redis cluster, a proxy cluster, a monitoring component and a configuration center, where the proxy cluster includes at least one proxy server, and each proxy server is provided with a configuration updating component, and the configuration center is configured to store master node information of each master node in the Redis cluster; in the scheme, when a monitoring component monitors that a target master node in a Redis cluster is abnormal, a target slave node corresponding to the target master node is switched to a new master node in time, and master node information corresponding to the target master node in the configuration center is updated to master node information of the new master node; each configuration updating component monitors the configuration center in real time, when the information of the main node in the configuration center changes, the configuration updating component updates the configuration of the main node of the corresponding proxy server according to the information of the main node in the current configuration center, and each proxy server can timely update the configuration of the main node according to the corresponding configuration updating component because each proxy server is provided with the configuration updating component, so that the data consistency problem of each proxy server in the master-slave switching period is reduced, and the configuration of each proxy server is updated through the configuration updating component in the embodiment without manual operation, so that the configuration updating efficiency of the proxy server is improved.
