Abstract

The invention discloses a system and method for downloading data. The system comprises a plurality of downloading clusters. Each downloading cluster comprises a Linux virtual server (LVS), at least two downloading node Nginx servers and a Hadoop distributed file system (HDFS), wherein an operating system of each downloading node Nginx server is used for mounting the storage service of the HDFS through a filesystem in userspace (FUSE); each LVS is used for receiving a downloading request of a user, performing scheduling selection on all Nginx servers and forwarding the downloading request to the selected Nginx server; the Nginx servers are used for accessing the data stored in the HDFS through the FUSE after receiving the downloading request forwarded by each LVS and responding to the downloading request of the user; and each HDFS is used for storing the data. According to the system and the method for downloading the data, the requirements of high stored data volume and great file number can be met, and moreover, the downloading service requirements when the access hotspots of part of service users are not concentrated can also be met.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data downloading system and method. Background technique [0002] With the development of information technology, people are increasingly accustomed to obtaining various data through the network. For example, a common way is to download desired content through a data download system. [0003] Currently, there are mainly two download architectures that are widely used, one is the traditional CDN (Content Delivery Network, content distribution network) multi-layer cache architecture, and the other is the download architecture that is commonly used by general video websites. [0004] The schematic diagram of CDN multi-layer cache architecture is as follows: figure 1 As shown, in this architecture, the global data is only stored in the top-level source site device, and each edge service node is reverse-proxyed by Nginx, which forwards the request to the back-end Squid, and Squi...
