With the rapid development of mobile internet technology, more and more data service providers employ distributed clusters to store data, thereby providing data services to users.
The scale of the distributed cluster is complex, and hardware resources (which may include the number of servers, the number of memories, the number of CPU cores, and disk IO) of servers on different nodes may be different, so that when the distributed cluster is deployed, different configurations need to be deployed at different nodes. In addition, when the distributed cluster is deployed, factors such as the size of the configurable service resource, the configurable node type or service type, and the configurable number of nodes need to be considered.
In the prior art, in order to simplify the process of deploying distributed clusters as much as possible, a plurality of different resource configuration file templates of the distributed clusters are pre-established, and when the distributed clusters need to be deployed, if the content of resources needed to be used by the framework of the distributed clusters to be deployed is the same as the content of resources needed to be used by the framework of the distributed clusters corresponding to one of the resource configuration file templates, the distributed clusters to be deployed can be directly deployed according to the cluster architecture definition description file corresponding to the resource configuration file template; if the resource content required to be used by the framework of the distributed cluster to be deployed is different from the resource content required to be used by the framework of the distributed cluster corresponding to any resource configuration file template, the distributed cluster to be deployed cannot be deployed directly according to the pre-configured cluster framework definition description file, and the generation of the cluster framework definition description file needs to be manually participated.

In order to solve the foregoing problems, embodiments of the present application provide a deployment method and apparatus for a distributed cluster, an electronic device, and a readable storage medium, which can improve efficiency of deploying the distributed cluster, and do not excessively limit a framework form of the distributed cluster.
The technology can be realized by adopting corresponding software, hardware and a combination of software and hardware. The following describes embodiments of the present application in detail.
First, referring to fig. 1, an embodiment of the present application provides a deployment method of a distributed cluster.
The steps involved will be described below with reference to fig. 1.
Step S110: acquiring a resource configuration file corresponding to a distributed cluster to be deployed, wherein the resource content represented by the corresponding resource configuration file is the resource content required by the distributed cluster.
In this embodiment of the application, when a background worker needs to deploy a new distributed cluster, attribute information of a server to be included in the distributed cluster needs to be configured in advance.
The attribute information may include basic information such as an IP address of each server, a name of the server, and a login password of the server, so that the server can be accessed based on the attribute information of the server, and resource information of the server is obtained.
In addition, the resource information includes a plurality of sub-resources, such as the number of servers, the total memory of the cluster servers, the total disk capacity of the cluster servers, the total CPU count of the cluster servers, the memory size of each server, the disk capacity of each server, the CPU count of each server, and the CPU core count, and each sub-resource has a corresponding attribute value, for example, there are three sub-resources, which are the number of servers, the total memory size of the cluster servers, the total CPU count of the cluster servers, and the memory size of each server, the CPU count, and the core count corresponding to the CPU.
It is to be noted that, in the embodiment of the present application, the number of entries of the sub-resources included in the resource information corresponding to each server cluster is the same.
The attribute value corresponding to the number of the servers is 3, and the representation distributed cluster comprises 3 servers; the attribute value corresponding to the total memory size of the cluster server is 50G, and the total memory size available for representing the distributed cluster is 50G (theoretical value); the attribute value corresponding to the total CPU number of the cluster server is 5, and the 3 servers representing the distributed cluster have 5 CPUs in total; the attribute value corresponding to the memory size of the server A is 16G, and the available memory size of the characterization server A is 16G (theoretical value); the attribute value corresponding to the number of the CPUs of the server A is 2, and the server A is characterized by having two CPUs; the attribute value corresponding to the number of CPU cores of server a is [14,24], and CPU No. 0 representing server a has 14 cores, and CPU No. 1 of server a has 24 cores.
That is, the resource information is used to characterize the total resource required to be allocated by each server included in the distributed cluster and the sub-resource required to be allocated by each server.
Of course, in the embodiment of the present application, after the resource information of the server is obtained, the resource information may be converted into a resource configuration file corresponding to the distributed cluster to be deployed. Of course, the above sub-resources and the attribute values corresponding to each sub-resource are also included in the resource configuration file.
It should be noted that, in the embodiment of the present application, since the number of entries of the sub-resources included in the resource information corresponding to each server cluster is the same, correspondingly, the number of entries of the sub-resources included in each resource configuration file is also the same.
Step S120: and determining the template resource configuration file from the resource configuration files currently existing in the database.
It should be noted that, in the embodiment of the present application, a large number of resource configuration files are stored in the database in advance, and these resource configuration files correspond to the distributed clusters deployed in the past one to one. For each resource profile, a plurality of sub-resources and attribute values corresponding to each sub-resource are included. Certainly, a large number of cluster architecture definition description files are also stored in the database, and each cluster architecture definition description file corresponds to each resource configuration file one to one, and certainly, each cluster architecture definition description file also corresponds to a distributed cluster deployed in the past one to one.
The cluster architecture definition description file is used for defining services of a corresponding distributed cluster, nodes on which the services are distributed, servers on which the nodes are distributed, memory, CPU (Central processing Unit) capacity, disk capacity and the like distributed by the nodes. It is to be appreciated that distributed clusters can be deployed according to a cluster architecture definition description file.
After the resource configuration file corresponding to the distributed cluster to be deployed is obtained, the resource configuration file corresponding to the distributed cluster to be deployed and each resource configuration file currently existing in the database can be compared, so that the cluster architecture definition description file for guiding the deployment of the distributed cluster, namely the cluster architecture definition description file corresponding to the distributed cluster, is obtained through the comparison result and the pre-stored cluster architecture definition description file.
In this embodiment of the present application, for any resource configuration file, when the content of the resource represented by the resource configuration file is identical to the content of the resource represented by the resource configuration file corresponding to the distributed cluster (it is stated that the attribute values corresponding to each sub-resource of the two are identical), it is determined that the resource configuration file is the second resource configuration file.
In some embodiments, when it is determined that the second resource configuration file exists in the database after the comparison, the cluster architecture definition description file corresponding to the second resource configuration file may be directly determined as the cluster architecture definition description file corresponding to the distributed cluster. That is, in this embodiment, the cluster architecture definition description file corresponding to the second resource configuration file is preferentially determined as the cluster architecture definition description file corresponding to the distributed cluster, so that the deployment efficiency is improved.
In this embodiment, when it is determined that the second resource configuration file does not exist in the database after the comparison, at this time, the cluster architecture definition description file corresponding to the distributed cluster cannot be directly acquired, the self-learning mode may be started, so as to determine one template resource configuration file from a plurality of resource configuration files currently existing in the database, and learn the resource configuration file corresponding to the distributed cluster, the template resource configuration file, and the cluster architecture definition description file corresponding to the template resource configuration file, thereby calculating a new cluster architecture definition description file and determining the new cluster architecture definition description file as the cluster architecture definition description file corresponding to the distributed cluster.
Of course, in some embodiments, the self-learning mode may also be directly started to determine the cluster architecture definition description file corresponding to the distributed cluster without determining whether the second resource configuration file exists.
The following will describe a self-learning mode.
In this embodiment of the present application, for any resource configuration file, when the content of the resource represented by the resource configuration file is partially the same as the content of the resource represented by the resource configuration file corresponding to the distributed cluster (it is stated that the categories of the sub-resources included in the resource configuration file are the same, but only the attribute values of the sub-resources in partial categories are the same), the resource configuration file is determined to be the first resource configuration file.
As mentioned above, a template resource configuration file may be determined from a plurality of resource configuration files currently existing in the database, and the cluster architecture definition description file corresponding to the distributed cluster may be calculated according to the resource configuration file corresponding to the distributed cluster, the template resource configuration file, and the cluster architecture definition description file corresponding to the template resource configuration file.
On this premise, it may be determined whether the first resource configuration file exists in all the resource configuration files currently existing in the database.
Optionally, when the first resource configuration file exists, the first resource configuration file is determined as the template resource configuration file.
Of course, there may be a case where multiple first resource profiles exist at the same time, and at this time, it is necessary to determine one first target resource profile from the multiple first resource profiles and determine that the first target resource profile is the template resource profile.
In some embodiments, a first resource profile may be randomly determined from a plurality of first resource profiles and determined to be a first target resource profile.
In other embodiments, the similarity between the resource content represented by each first resource configuration file and the resource content represented by the resource configuration file corresponding to the distributed cluster may be calculated first, and then the first resource configuration file corresponding to the highest similarity may be selected as the first target resource configuration file.
In addition, in some embodiments, when determining whether the first resource profile exists in all resource profiles currently existing in the database, the determination result may be that the first resource profile does not exist currently, that is, the content of the resource represented by all resource profiles currently existing in the database is completely different from the content of the resource represented by the resource profile corresponding to the distributed cluster.
To address this situation, the background staff may configure a minimum resource configuration file in advance in the database, and the category and the number of items of the child resources included in the minimum resource configuration file are the same as those included in the other source configuration files. In addition, there are attribute values corresponding to each sub-resource within the minimum resource profile. That is, the minimum resource profile may be used to describe the minimum resources required by each service module (unit) of the distributed cluster.
Correspondingly, there is a cluster architecture definition description file corresponding to the minimum resource configuration file, for describing the distributed cluster that can be deployed by the resource configuration listed by the minimum resource configuration file.
In some embodiments of the present application, when it is determined that the first resource profile does not exist, the smallest resource profile is determined to be the template resource profile.
Step S130: and generating a cluster architecture definition description file corresponding to the distributed cluster according to the corresponding resource configuration file, the template resource configuration file and the cluster architecture definition description file corresponding to the template resource configuration file.
As mentioned above, the cluster architecture definition description file corresponding to each resource configuration file is stored in the database.
After the template resource configuration file is determined, for each sub-resource included in the resource configuration file corresponding to the distributed cluster, the resource configuration file corresponding to the distributed cluster and the attribute value corresponding to the sub-resource in the template resource configuration file can be respectively obtained, and then, a ratio R between the attribute value corresponding to the sub-resource in the resource configuration file corresponding to the distributed cluster and the attribute value corresponding to the sub-resource in the template resource configuration file is calculated.
When R has a decimal, a decimal of a preset number of digits (for example, two decimal places) may be reserved, thereby ensuring data uniformity.
After the ratio R of each sub-resource is calculated, according to the ratio R of each sub-resource and the distribution condition corresponding to the sub-resource in the cluster architecture definition description file corresponding to the template resource configuration file, the resource distribution condition corresponding to the sub-resource in the cluster architecture definition description file corresponding to the distributed cluster (distributed cluster to be deployed) is determined, and therefore the cluster architecture definition description file corresponding to the distributed cluster is obtained. That is, after determining the resource allocation condition corresponding to each sub-resource in the cluster architecture definition description file corresponding to the distributed cluster, the cluster architecture definition description file corresponding to the distributed cluster can be obtained.
Specifically, assuming that the attribute value of the sub-resource a in the resource profile corresponding to the distributed cluster is a1, and the attribute value in the template resource profile is a2, the ratio R corresponding to the sub-resource a is a1/a 2. Subsequently, the resource allocation condition a4 corresponding to the sub-resource a in the cluster architecture definition description file corresponding to the distributed cluster (distributed cluster to be deployed) is determined through R and the allocation condition corresponding to the sub-resource a in the cluster architecture definition description file corresponding to the template resource configuration file (of course, the allocation condition is also presented in a numerical form, and is represented by a3 here, for example).
The process of determining a4 may be as follows.
In the embodiment of the present application, a corresponding maximum module value max (a) and a unit module value min (a) are set in advance for the attribute value of each sub-resource. The maximum module value max (a) and the unit module value min (a) of each attribute value are set by background staff according to actual conditions.
Wherein, R is multiplied by a3 to obtain b 0.
For b0, compare the magnitude relationship between b0 and max (a), if b0> max (a), then a4 equals max (a).
If b0 ≦ max (a), then c, c ≦ max (1, b0/min (a)) is calculated. Wherein, the result obtained by b0/min (a) only takes the quotient. a4 ═ c × min (a).
After the resource allocation condition corresponding to each sub-resource is obtained, a cluster architecture definition description file corresponding to the distributed cluster can be generated, wherein the cluster architecture definition description file corresponding to the distributed cluster has the same content of the described sub-resources as compared with the cluster architecture definition description file corresponding to the template resource configuration file, and is different from the resource allocation condition of each sub-resource.
Of course, it should be noted that, when the resource allocation condition of the corresponding sub-resource in the cluster architecture definition description file changes, the architecture of the distributed cluster used by the cluster architecture definition description file for guiding deployment changes accordingly.
Of course, after the new resource configuration file and the new cluster architecture definition description file are acquired, the new resource configuration file and the new cluster architecture definition description file may also be stored in the database, so that the resource configuration file and the cluster architecture definition description file acquired this time may be used when the distributed cluster is deployed subsequently.
Step S140: and deploying the distributed cluster according to the cluster architecture definition description file corresponding to the distributed cluster.
