Detailed ways

In order to make the purposes, 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 and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

Example 1

Embodiment 1 of the present invention provides a method for downloading resource pool software. FIG. 1 is a schematic flowchart of a method for downloading resource pool software in Embodiment 1 of the present invention. As shown in Figure 1, the method for downloading resource pool software in Embodiment 1 of the present invention includes the following steps:

S101: When a software request sent by a host is received, determine whether there is a software resource corresponding to the software request in the resource pool agent.

S102: When there is no software resource corresponding to the software request in the resource pool agent, send a request message for the software resource.

S103: Receive the software resource fed back by the yum source, and send the fed back software resource to the host and save it to the resource pool agent.

Further, the method for downloading software in a resource pool further includes: when there is a software resource corresponding to the software request in the resource pool agent, sending the software resource in the resource pool agent to the host.

Further, the software request includes request version information, and before sending the software resources in the resource pool agent to the host, it also includes: acquiring the information of the software resources in the resource pool agent. Save the version information; according to the requested version information and the saved version information, determine whether the saved version of the software resource is lower than the requested version; when the saved version is lower than the requested version, send the information of the software resource. request message; receive the software resource of the requested version fed back by the yum source, send the software resource of the requested version to the host and save it to the resource pool agent.

Still further, after sending the requested version of the software resource to the host and saving it to the resource pool agent, the method further includes: deleting the saved version of the software resource in the resource pool agent.

That is to say, when the host requests software resources from the resource pool, the request is forwarded through the resource pool proxy, and the request path of the yum source --> resource pool proxy --> resource pool host is established. For the software resource request of the host, first pass the resource pool proxy, if there are corresponding software resources, it can directly return to the host; otherwise, the resource request is forwarded to the yum source through the resource proxy pool, and the corresponding software resources are returned to the resource proxy The resource proxy pool then returns the host's request and caches the software resources in the resource proxy pool, so that the next request can be processed directly through the resource proxy pool. The specific implementation process is shown in FIG. 3 .

It can be seen that, unlike the current method of creating a complete image in the resource pool, because this method creates a complete image, there is no way to distinguish which software resources need to be used in the resource pool, there are a lot of redundancy, and there is no way to fit the public cloud. Scenes. The resource pool software download method provided in Embodiment 1 of the present invention processes the resource request of the host by means of a resource pool proxy, and only needs to download the software resources requested by the host in the resource pool proxy, so as to realize the on-demand downloading of software resources, by This eliminates the need to synchronize each yum source image, reduces redundant operations for creating images, and can effectively handle requests from the host. The maximum sharing of resource pools, the most efficient utilization, and the most cost-saving.

In order to improve the efficiency of responding to user requests, the software resource update method adopts the LRU algorithm. Specifically, the saving of the software resources to the resource pool agent includes the following methods: judging whether the resource pool agent is full; when the resource pool agent is full, using an LRU algorithm to save the software resources to the resource pool agent; when the resource pool agent is not full, save the software resource to the free pool of the resource pool agent.

Illustratively, the algorithm flow is shown in FIG. 3: the data that is frequently used in the recent period of time will be retained in the cache, and the data that has not been frequently used recently will be eliminated. When replacing content, it is only necessary to find the least recently used data to replace. The LRU maintains a content list in the cache, storing the most recently used data. When data is requested, it will jump to the first place. If the requested data is in the list, i.e. in the cached storage (eg in the Kth position), then the data position before K will be moved back one place and no content will be eliminated.

In order to describe the resource pool software downloading method according to Embodiment 1 of the present invention in more detail, a specific example is given. When the resource pool host needs to download software, for example, to request to download a python package, use the yum install python command to download:

1. The host sends a request to the resource pool agent to download the python package and its dependent packages;

2. The resource pool agent determines whether there is a local cache of the corresponding python package and its dependent packages, and if so, directly returns the resource to the host for installation; if not, proceed to the next step;

3. The resource pool agent obtains the corresponding software resources from the yum source, caches them locally after downloading, uses the LRU algorithm to update the resource pool, and returns the relevant packages requested by the host to the host.

4. Special circumstances: If the resource pool agent finds that there is an old version of the software locally during the download, it will delete the old version of the software, that is, only keep the latest software used in the resource pool.

It can be seen that the method for downloading software on demand from the resource pool provided in Embodiment 1 of the present invention processes the request of the host by means of the resource pool proxy, so as to achieve better management of the yum source. After the yum source is updated, no It is then necessary to perform the synchronization operation of each yum source mirror to reduce the redundant operation of creating mirrors, and at the same time, it can effectively handle the request of the host. By adding the resource pool agent, the calculation time of the resource pool management system is greatly reduced, the calling speed of the server is accelerated, the resource calling efficiency of the resource pool is improved, and the resource utilization rate of each server is improved at the same time.
