Description
Technical Field
The invention belongs to the technical field of cloud platform resource management, and particularly relates to a method for modifying Kafka cluster parameters on a cloud management platform.
Background
On the cloud service platform, a service selling Kafka middleware clusters is provided for users, and meanwhile, a function of modifying cluster parameters is also provided. A cluster is composed of multiple machines, and modifying the parameters of the cluster, in fact, each machine, is accompanied by a problem of modifying or not modifying if, while modifying the parameters, one or more machines in the cluster are in a failure state or for some reason are not accessible to them? If the parameters of the machines in normal state can only be modified if the parameters are modified, the problem that the parameters of a part of machines in a cluster are not synchronous occurs after the fault machines are repaired.
Thus, no matter which scheme is adopted, all users can not be satisfied.
The existing technical schemes include the following two types:
first, parameters can be modified only if the cluster state is normal, and modification is not permitted if one or more machines are not normal.
Second, when the parameters are modified, only the state of the normal machine is modified, and the machine with abnormal state is ignored.
The prior technical scheme has the following defects:
for the first scheme, the fault of several machines in a general cluster does not affect the use of a user, and the user is not allowed to modify parameters reasonably. There may be some user dissatisfaction.
According to the second scheme, when parameters are modified, only the state of a normal machine is modified, and machines with abnormal states are ignored. Thus, after the failed machine is recovered, the problem that the parameters of all the machines in a cluster are inconsistent is caused. The normal use of the cluster may be affected or the user may be confused and dissatisfied.
Disclosure of Invention
In view of the above, to overcome the above drawbacks, the present invention is directed to a method for modifying Kafka cluster parameters on a cloud management platform.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a method for modifying Kafka cluster parameters on a cloud management platform comprises the following steps:
s1, defining an interface for modifying parameters, adding an optional parameter in the interface, wherein the name is 'forced modification';
s2, the user clicks a modification parameter interface on the UI interface, the UI calls the interface defined in the step S1, and the parameter of 'forced modification' is not transmitted in the interface;
and S3, processing the interface according to the internal logic of the interface after receiving the request, directly modifying the parameters if no abnormal machine exists, returning to the step of successful modification, finishing the operation, and returning to the step of failed modification if the abnormal machine exists, and prompting the abnormal state.
In step S1, the logic in the interface is as follows;
s101, if the parameter of 'forced modification' is not transmitted, judging the state of each node, if one is not in a normal state, ending the program, and returning that the node is in an abnormal state
S102, modifying parameters of all normal nodes, and ignoring the nodes in abnormal states.
Further, in step S3, after the UI receives the result of "modify successfully", the UI prompts the user that the modification is successful, and the operation is ended.
Further, in step S3, after receiving the result of "failure to modify, prompting that the state is abnormal", the UI pops up a prompt to the user that "whether the current cluster has abnormal node state, and only modifies the parameters of the normal nodes";
after seeing the prompt of whether the current cluster has abnormal node state and only modifies the parameters of normal nodes, the user selects to continue modifying or cancel according to the condition of the user;
if the user selects to cancel the interactive operation, the interactive operation is completed;
if the user selects 'continue modification', the UI continues to call an interface for modifying the parameters, and adds a 'forcibly modified' parameter in the interface;
and after receiving the request of forced modification, the background service interface modifies the parameters of the normal state of all the instances for the user.
Compared with the prior art, the method for modifying the Kafka cluster parameters on the cloud management platform has the following advantages:
the method for modifying Kafka cluster parameters on the cloud management platform provided by the invention realizes that a user determines whether to modify the cluster parameters according to the actual situation of the user under the condition that the cluster state is abnormal.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate an embodiment of the invention and, together with the description, serve to explain the invention and not to limit the invention. In the drawings:
fig. 1 is a flowchart of a method for modifying Kafka cluster parameters on a cloud management platform according to the present invention.
Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
The embodiment provides a method for modifying Kafka middleware cluster parameter configuration on a cloud service platform, as shown in fig. 1, the specific technical scheme is as follows:
1. an interface for modifying parameters is defined, and an optional parameter is added into the interface, wherein the name of the optional parameter is 'forced modification'.
The logic in the interface is as follows;
the first step is as follows: if the parameter of 'forced modification' is not transmitted, judging the state of each node, if one is not in a normal state, ending the program, and returning to the abnormal state of the node;
the second step is that: modifying parameters of all normal nodes, and ignoring nodes with abnormal states;
2. the user clicks the interface for modifying the parameters on the UI interface, the UI calls the interface defined above, and the parameter of 'forced modification' is not transmitted in the interface.
3. After receiving the request, the interface processes according to the internal logic of the interface, if there is no abnormal machine, the parameters are directly modified, the modification is returned successfully, the operation is finished, if there is abnormal machine, the modification is returned failed, and the abnormal state is prompted.
4. And after the UI receives the result of 'successful modification', the UI prompts the user that the modification is successful, and the operation is finished.
5. After the UI receives the result of ' failure in modification and abnormal prompt state ', a prompt is popped up to the user to indicate whether the current cluster has abnormal node state and only modifies the parameters of normal nodes '
6. After seeing the prompt of whether the current cluster has abnormal node state and only modifies the parameters of normal nodes, the user selects to continue modifying or cancel according to the condition of the user.
7. If the user selects "cancel". And finishing the interactive operation.
8. If the user selects the 'continue modification' UI, the interface for modifying the parameters is called continuously, and the parameters of 'forced modification' are added in the interface.
9. And after receiving the request of forced modification, the background service interface modifies the parameters of the normal state of all the instances for the user.
The above flow is what the patent wishes to protect, and defines a set of ways to modify Kafka middleware cluster parameters on the solution cloud platform, by adding a "mandatory modification" parameter in the interface.
The method and the device realize that the user can determine whether to modify the cluster parameters according to the actual situation of the user under the condition that the cluster state is abnormal.
