Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
The service control method provided by the present disclosure is explained in detail by one or more embodiments described below.
Fig. 1 is a schematic view of an application scenario provided by an embodiment of the present disclosure, where fig. 1 includes a client 11 and a server 12, specifically, the client 12 and a vehicle 11 may be referred to, the vehicle 11 is in communication connection with the cloud 12, and the vehicle 11 may be a vehicle with an automatic driving function. A large number of services are deployed on the cloud 12, and the services deployed on the cloud 12 are used for implementing operation and maintenance of the vehicle 11, for example, a network service, a permission service, a vehicle shadow service, and the like provided by the cloud 12, so that a user can better use an automatic driving function of the vehicle 11, and data communication is performed between the vehicle 11 and the cloud 12 through the services deployed on the cloud 12. The method provided by the embodiment of the disclosure is applicable to the server 12, the server 12 determines the running state of the service running on the server, and when the running state of the service is unavailable, the security service corresponding to the service is started, that is, the low-version service of the service is started, the low-version service can be stored in the server 12 in a cold standby mode, the cold standby mode is that the security service corresponding to the service is started only when the service is unavailable, and if the service is available, the security service is only stored in the server but is not running.
In one embodiment, the method for the server 12 to determine the operation state of the service running on the server includes: acquiring the number of available copies corresponding to the service and the number of times of restarting the service; and determining the running state of the service according to the number of the available copies and the restarting times, wherein the running state comprises a normal state, a waiting state and a failure state.
It can be understood that fig. 2 is a schematic diagram of an application scenario provided by the embodiment of the present disclosure, fig. 2 includes a cloud 210 and a backup cloud 220 of the cloud 210, the cloud 210 includes a cluster 211 and a backup cluster 212 of the cluster 211, the cluster 211 includes 3 copies, which are a copy 213, a copy 214 and a copy 215, and the 3 copies implement related functions of the same service, and can be understood as a program to implement the related functions of the service, where the copy 213 can be a copy in the cluster 211 as a copy for receiving a processing request, the copy 214 and the copy 215 can be understood as backup copies with respect to the copy 211, the copy 213, the copy 214 and the copy 215 can be simultaneously run, and backup can be performed between the 3 copies in a hot standby manner, where hot standby refers to running multiple sets of services in the whole cluster, all requests are received and processed by only one set of services, and when one or more services in the set of services cannot normally run, and when the request is switched to the corresponding backup service, the data among the 3 copies are synchronized in real time, and the switching time is shorter by adopting a hot standby mode. For example, the copy 214 corresponding to the backup service may be enabled after the copy 213 fails to operate normally, and the backup copy 215 may be enabled when the copy 214 fails to operate normally. The cluster 212 is a backup cluster of the cluster 211, the cloud 220 is a backup cloud of the cloud 210, when the service copy 213 in the cluster 211 in the cloud 210 cannot normally operate, the backup copy 214 or the copy 215 on the cluster 211 is preferentially enabled, if the copy 214 and the copy 215 cannot normally operate, the backup cluster 212 is switched to, the copy 216 or other copies running on the backup cluster 212 are enabled, if multiple copies running on the backup cluster 212 cannot normally operate, the backup cloud 220 is enabled, that is, a switching rule between services may be that service switching is preferentially performed in the same cluster, service switching between clusters in the same cloud is performed, finally service switching between different clouds is performed, so that switching speed can be increased to the maximum extent, and switching cost can be reduced.
It is understood that the service state determination method may be executed by a state machine, the state machine may also be deployed in the cluster 211, or in the cloud 210, or one state machine may be deployed in each cluster, the state machine may be understood as a mechanism for monitoring a service state, and a state machine entity may be a program. When the cluster 211 is restarted or initialized, the state machine may be automatically started to monitor the running state of the service on the cluster at any time, and the following embodiments will be described by taking the state machine in the cluster 211 as an example, and the manner of the state machine in the cloud is similar, which is not described herein again. The state machine obtains the number of available copies of a service running on the cluster and the number of restart times of the service, where an available copy refers to the number of copies that can run normally, and the number of restart times of the service may be an accumulated number of restart times of all copies corresponding to the service, or may be a number of restart times of each copy corresponding to the service running on the cluster, for example, the number of available copies of the service in the cluster 211 in fig. 2 is 3, that is, the copy 213, the copy 214, and the copy 215 may run normally, and the number of restart times of the service may be zero at this time. In some embodiments, the number of restarts may also be different from zero, the state machine is not necessarily enabled synchronously with the cluster 211, and there may be a case where the state machine is enabled or initialized after the cluster 211 has been operated for a period of time, for example, during the operation of the cluster 211, a service is restarted, that is, there is a number of restarts for the service, and if there is an available copy of the service in the cluster 211, that is, the service is in a normal state in the cluster 211, but the number of restarts for the service is different from zero.
Optionally, the determining the running state of the service according to the number of available copies and the number of restart times specifically includes the following steps: if the number of the available copies is larger than or equal to a first preset threshold value, determining that the running state of the service is a normal state; if the number of the available copies is smaller than a first preset threshold value and the number of restarting times is smaller than a second preset threshold value, determining that the running state of the service is a waiting state; and if the number of the available copies is less than a first preset threshold value and the restarting times is greater than or equal to a second preset threshold value, determining that the running state of the service is a failure state.
It can be understood that if the number of available copies of the service acquired by the state machine is greater than or equal to a first preset threshold, the running state of the service may be directly determined to be a normal state, where the first preset threshold may be 1, that is, if at least one copy that can be normally run and used exists on the cluster 211, it is indicated that the service running on the cluster 211 is a normal state.
It can be understood that if the number of available copies of the service acquired by the state machine is less than a first preset threshold, and the recorded number of times of restarting the service is less than a second preset threshold, the running state of the service may be directly determined to be a waiting state, where the second preset threshold may be 10, and the number of times of restarting the service may be the number of times of restarting each copy corresponding to the service running on the cluster. For example, if there is no copy capable of being used in normal operation on cluster 211, that is, 3 copies in cluster 211 are not available, and the number of times of restarting each copy in the 3 copies is less than 10, it may be determined that a service running on cluster 211 is in a waiting state, where there is an unavailable copy that is restarting. It is understood that when the copy 213 is not available, the copy 213 is automatically switched to the copy 214, and the copy 213 is automatically restarted, when the copy 214 is also not available, if the copy 213 is still in the restart at this time, the copy 215 may be switched to, and the copy 214 is also automatically restarted, and when 3 copies are not available and the number of restarts of each copy in the 3 copies is less than 10, it may be determined that the service running on the cluster 211 is in the waiting state. The first preset threshold and the second preset threshold can be determined according to requirements of related personnel.
It can be understood that if the number of available copies of the service acquired by the state machine is less than a first preset threshold and the recorded restart times of the service are greater than or equal to a second preset threshold, the running state of the service may be directly determined to be a failure state, where the failure state in this case means that all copies corresponding to the service on the cluster 211 are unavailable, and when the restart times are relatively large, it indicates that the service is in the failure state, and at this time, the service is completely unavailable or cannot run.
In another embodiment, the method for determining whether the service is available or not, that is, determining whether the service is in a failure state or a normal state, may specifically include: acquiring the number of available copies corresponding to the service; and determining the running state of the service according to the number of the available copies, wherein the running state comprises a normal state and a failure state.
Understandably, the state machine in cluster 211 obtains the number of available copies of the service running on cluster 211, i.e., determines how many copies in cluster 211 are available to function properly.
It will be appreciated that the method does not include a wait state, i.e., no wait timeout mechanism is set or enabled in the state machine, and the running state of the service includes only a normal state and a failed state. The running state of the service can be determined only by the number of available copies of the service, and the restarting times of the service do not need to be acquired.
Understandably, according to the number of available copies, determining the running state of the service, wherein the running state comprises a normal state and a failure state, and specifically comprises the following steps: if the number of the available copies is larger than or equal to a first preset threshold value, determining that the running state of the service is a normal state; and if the number of the available copies is less than a first preset threshold value, determining that the running state of the service is a failure state.
It can be understood that if the number of available copies of the service acquired by the state machine is greater than or equal to a first preset threshold, the running state of the service may be directly determined to be a normal state, where the first preset threshold may be 1, that is, if at least one copy that can be normally run and used exists on the cluster 211, it is indicated that the service running on the cluster 211 is a normal state.
