Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Currently, in the prior art, the following two problems mainly exist in the process of redirection:
1. each cluster is used for periodically calculating the hot spot resources in the cluster, and the calculation mode of the hot spot resources increases the resource overhead of the database and the load of a management process. The database of the cache cluster management server records information such as the size, creation time, latest service time, service connection times, service flow and the like of cached resource files, and the recording quantity of the file resources usually reaches tens of millions.
2. After the process is restarted, the monitoring server loads a large number of hot spot resources of other clusters besides the resources in the cluster, so that high requirements are put forward on the memory capacity of the monitoring server, the resource loading time is prolonged, and the resource records loaded into the memory are frequently updated, which affects the redirection efficiency.
To solve the above problem, fig. 1 is a schematic flow diagram of a cross-cluster redirection method provided by an embodiment of the present invention, and as shown in fig. 1, the method includes:
110. if the target resource is not cached in the first cluster, sending a resource retrieval instruction to each cluster except the first cluster in the cloud cache to determine a target cluster containing the target resource;
120. and sending the IP address of the cache server corresponding to the target cluster and the storage path of the target resource on the disk of the cache server corresponding to the target cluster to a terminal through 302 redirection messages.
It should be noted that the main execution body in the embodiment of the present invention is a monitoring server in the first cluster, and when the monitoring server receives a target resource retrieval request sent by a terminal and there is no target resource in the first cluster, the cross-cluster redirection scheme provided in the embodiment of the present invention needs to be used to obtain the target resource in another cluster.
It should be further noted that the cross-cluster redirection scheme provided by the embodiment of the present invention is suitable for provinces where multiple clusters are deployed, and since each cluster is deployed in the same province, the number of route hops through which equipment communicates between computer rooms is small, and a network outlet computer room is connected to a network outlet computer room or a direct link is provided, so that bandwidth and communication quality are guaranteed. The monitoring servers are all configured with public network IP addresses, the servers among different clusters can access each other, the network delay is in millisecond level, and the possibility of searching the memory resources of the monitoring servers among different clusters is provided.
In step 110, the cloud cache is a cloud cache set formed by all clusters including the first cluster, and the cloud cache can well solve the problem that the same resource repeatedly returns to the source in a plurality of clusters. After the cloud cache sharing function is started by each cluster, the management server of each cluster periodically calculates the hot spot resources in the cluster, and then the hot spot resources are periodically synchronized to other clusters. The monitoring server loads hot spot resources of other clusters regularly, when the resources accessed by the user are not cached in the cluster, but the other clusters are cached, the monitoring server informs a cache server in the cluster, the user requests to the cache server of the other clusters to obtain the resources by acting, and meanwhile, file copies are reserved locally.
It should be noted that, when the number of times of accessing the specific resource in the cluster reaches the trigger threshold of the cloud cache, the resource is changed into a locally cached resource in the recorded database of the cluster.
In step 110, the resource retrieving is a process of retrieving, from other clusters, which cluster can provide the target resource when the target resource is not cached in the current cluster and the target resource is cached in other clusters. An optimal cluster capable of providing target resources is determined from a plurality of clusters included in the cloud cache through resource retrieval, and the optimal cluster is used as a target cluster.
Further, after the target cluster is determined in step 110, in step 120, the IP address of the cache server and the storage path of the target resource on the disk of the cache server corresponding to the target cluster may be determined according to the storage of the target resource in the determined target cluster, and then these information may be sent to the terminal in the form of 302 redirection message. Therefore, the terminal can directly obtain the resources from the cache server of the target cluster.
According to the cross-cluster redirection method provided by the embodiment of the invention, the cluster is subjected to cloud caching, and cross-cluster redirection is performed in the cloud caching, so that the resource loading time in the starting process of the monitoring process can be effectively reduced, the memory resource consumption of the monitoring server can be reduced, and the pressure of the service process and the database of each cluster management server can be effectively reduced.
On the basis of the foregoing embodiment, if it is detected that the target resource is not cached in the first cluster, the sending a resource retrieval instruction to each cluster except the first cluster in the cloud cache to determine the target cluster including the target resource includes:
loading the resource directory of the first cluster, and detecting whether the target resource is contained in the resource directory of the first cluster;
if the target resource is not detected in the resource directory of the first cluster, sending a resource retrieval instruction to monitoring servers corresponding to clusters except the first cluster in a cloud cache to determine a target monitoring server containing the target resource;
and determining the target cluster according to the determined target monitoring server.
As can be seen from the content of the foregoing embodiment, the cross-cluster redirection method provided in the embodiment of the present invention can retrieve the content of other cluster caches in the cloud cache, determine the target cluster containing the target resource, and direct the terminal to directly acquire the target resource from the target cluster through the 302 redirection message.
The specific determination process for the target cluster is as follows: only the resource record of the current cluster, that is, the first cluster, is loaded, and the resource records of other clusters in the cloud cache are not loaded any more, so that for the resource which is not cached in the current cluster but is cached in other clusters, the monitoring server of the first cluster can perform resource retrieval to the monitoring servers of other clusters in real time, thereby determining the target monitoring server containing the target resource.
It can be understood that there is a corresponding relationship between the monitoring server and the cluster, so that after the target monitoring server is determined, the target cluster can be correspondingly determined.
On the basis of the foregoing embodiment, the sending a resource retrieval instruction to a monitoring server corresponding to each cluster in a cloud cache except for the first cluster to determine a target monitoring server including the target resource includes:
simultaneously sending a resource retrieval instruction to a monitoring server corresponding to each cluster except the first cluster in the cloud cache, wherein the resource retrieval instruction is used for indicating the monitoring server to perform target resource retrieval in a memory of the monitoring server;
and taking the first monitoring server which carries out retrieval response reply according to the resource retrieval instruction as the target monitoring server.
As can be seen from the above description of the embodiments, the embodiments of the present invention are resource search performed in the monitoring server corresponding to the cluster. Specifically, the resource retrieval scheme provided in the embodiment of the present invention is that the monitoring server of the first cluster simultaneously sends the resource retrieval instruction to the monitoring servers of other clusters. The resource retrieval instruction can instruct the monitoring servers of other clusters to perform target resource retrieval in the memories of the monitoring servers, and the monitoring servers of the clusters do not need to perform retrieval in the management server database of the clusters as in the prior art.
In addition, the method provided by the embodiment of the invention adopts one-time batch sending when sending the resource retrieval instruction, and aims to shorten the resource retrieval times, improve the single retrieval quantity and further improve the resource retrieval performance.
It should be noted that, because the number of monitoring servers included in the cluster is large, data is loaded in the memory, the resource retrieval speed is fast, and the resource retrieval is balanced to all monitoring servers. The scheme for resource retrieval in the memory of the monitoring server provided by the embodiment of the invention avoids the pressure of retrieval from different cluster monitoring servers to the cluster management server database, and can also improve the retrieval efficiency.
Further, each monitoring server will detect whether the resource record contains the target resource after receiving the resource retrieval instruction, and if so, a corresponding retrieval response reply needs to be made, so as to inform the monitoring server of the first cluster. Then, since the sending is performed to all clusters simultaneously in the sending process, but the response speeds of different clusters may be different, in consideration of the retrieval speed, the embodiment of the present invention preferentially uses the monitoring server corresponding to the first received retrieval response reply as the target monitoring server, and the next received retrieval response replies are discarded.
On the basis of the foregoing embodiment, the taking the first monitoring server that performs the retrieval response reply according to the resource retrieval instruction as the target monitoring server further includes:
and if the information of searching response reply of any monitoring server according to the resource searching instruction is not received within the preset time, sending the information of resource request acquisition failure to the terminal.
As can be seen from the content of the foregoing embodiment, the solution monitoring server provided in the embodiment of the present invention needs to perform a retrieval response reply according to the resource retrieval instruction. In consideration of timeliness of resource retrieval, in the embodiment of the invention, when the monitoring server sends the resource retrieval instruction, the timer is started to time, and no retrieval response reply of other cluster monitoring servers is received within a specified time, the resource requested by the user is considered to be not cached in all cache clusters, the monitoring server informs the management server of the request of the user for the resource, the management server uniformly records the access times of the resource, and meanwhile, the monitoring server gives up the action of guiding the terminal to redirect and obtain the resource.
On the basis of the above embodiment, each cluster in the cloud cache corresponds to one or more monitoring servers, and the resource records loaded by each monitoring server corresponding to each cluster are the same.
It should be noted that, in the embodiment of the present invention, each monitoring server is grouped in advance, and the grouping standard is performed according to a cluster, that is, all monitoring servers in the same cluster are distributed in the same group.
Then, since the resource records loaded by all the monitoring servers in the same cluster are completely consistent, the resource retrieval is performed only in the memory of a specific monitoring server in each cluster, for example: in a cloud cache system consisting of N clusters, the monitoring server only needs to search resources on N-1 monitoring servers, so that the resource searching overhead among different clusters is minimized.
As can be seen from the above, when resource search is performed, each cluster corresponds to a specific monitoring server, and search is directly performed on the specific monitoring server. However, in order to avoid the problem that a part of monitoring servers obtain too many retrieval requests and another part of monitoring servers obtain too few retrieval requests, it is necessary to reasonably distribute the request load on each cluster monitoring server. Therefore, the embodiment of the invention also provides a scheme that one cluster corresponds to a plurality of monitoring servers.
For convenience of description, the embodiment of the present invention is described in a manner that one cluster corresponds to two monitoring servers, but the embodiment of the present invention does not specifically limit the corresponding number of the clusters and the monitoring servers.
In the embodiment of the invention, one cluster corresponds to two monitoring servers, wherein one monitoring server is a main server, and the other monitoring server is an auxiliary server. For example: the monitoring server 1 of the cluster 1 performs resource retrieval on the target servers of the monitoring server 1 and the monitoring server 2 of the cluster 2, the monitoring server 1 of the cluster 2 is a main server, the monitoring server 2 of the cluster 2 is a standby server, and the standby server provides service under the request that the main server cannot provide service. TCP connection is established in advance between each monitoring server in the cluster 1 and the corresponding monitoring server in the cluster 2, and connection multiplexing is carried out, so that the resource retrieval speed can be effectively accelerated.
On the basis of the above embodiment, the method further includes:
when one cluster corresponds to a plurality of monitoring servers, for any one cluster, if the resource retrieval instruction sent to the monitoring server corresponding to the cluster fails, the resource retrieval instruction is sent to another monitoring server corresponding to the cluster again through a preset redundant path.
As can be seen from the foregoing description of the embodiments, the cluster provided in the embodiments of the present invention may correspond to one or more monitoring servers. And one of them is used as a main server, and the other monitoring servers are used as secondary servers for alternative. Then when the resource retrieval instruction fails to be sent to the primary server, a new primary server needs to be selected from the secondary servers to resend the resource retrieval instruction. Specifically, the embodiment of the present invention may be implemented by establishing a redundant path between the server and the sending-end monitoring server.
On the basis of the foregoing embodiment, the sending the IP address of the cache server corresponding to the target cluster and the storage path of the target resource on the disk of the cache server corresponding to the target cluster to the terminal through a 302 redirection message includes:
determining a cache server for storing target resources based on the resource monitoring record of the target monitoring server corresponding to the target cluster;
and sending the IP address information of the cache server and the storage path information on the disk of the cache server corresponding to the target cluster to the terminal through a 302 redirection message.
As can be seen from the content of the foregoing embodiment, the monitoring server of the first cluster provided in the embodiment of the present invention does not load the resource records of other clusters any more, but only loads the resource records of the first cluster. And aiming at the resources which are not cached in the first cluster but are cached in other clusters, the monitoring server carries out resource retrieval on the monitoring servers of other clusters in real time, sends a redirection message according to the retrieval result and guides the user to the servers of other clusters having the resources to obtain the resources. The direction of user requests is no longer limited to the inside of the cluster, but extends to the various clusters that make up the cloud cache.
According to the retrieval result on the target monitoring server, the server IP address information stored by the resource and the storage path of the resource on the disk can be integrated, and the information is sent to the terminal by the 302 redirection message, wherein the IP address of the Location field of the 302 redirection message points to the IP address of the cache server owned by other clusters, but not the IP address of the cache server of the first cluster, so that the cross-cluster redirection guidance of the user for directly obtaining the resource from the cache servers of other clusters is realized.

the determining module 210 is configured to, if it is detected that the target resource is not cached in the first cluster, send a resource retrieval instruction to each cluster except the first cluster in the cloud cache to determine a target cluster including the target resource;
the redirection module 220 is configured to send the IP address of the cache server corresponding to the target cluster and the storage path of the target resource on the disk of the cache server corresponding to the target cluster to the terminal through a 302 redirection message.
Specifically, how to perform cross-cluster redirection through the determining module 210 and the redirecting module 220 may be used to execute the technical solution of the cross-cluster redirection method embodiment shown in fig. 1, and the implementation principle and the technical effect are similar, which are not described herein again.
According to the monitoring server provided by the embodiment of the invention, the cluster is subjected to cloud caching, and cross-cluster redirection is performed in the cloud caching, so that the resource loading time in the starting process of the monitoring process can be effectively reduced, the memory resource consumption of the monitoring server can be reduced, and the pressure of the service process and the database of each cluster management server can be effectively reduced.
