A cluster access system, method and device

Abstract

The embodiment of the present invention provides a cluster access system, method and device. In the method, the proxy server first receives the target request for accessing the target cluster sent by the target client; determines the first master node from each master node of the target cluster node; send the target request to the first master node; then receive the feedback information fed back by the first master node; judge whether the feedback information is steering information; if so, analyze and obtain the node identifier from the feedback information as the first An identifier; sending the target request to the master node corresponding to the first identifier, so that the master node corresponding to the first identifier responds to the target request. In the solution provided by the embodiment of the present invention, the client communicates with the cluster through the proxy server, and the proxy server completes the interaction between the client and the cluster. The access operations required by the client are simple and not cumbersome, and the expansion of the cluster is fully No effect.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a cluster access system, method and device. Background technique [0002] A cluster is a group of independent computers interconnected by a high-speed network that form a group and are managed as a single system. When a client interacts with the cluster, the cluster is like an independent server, providing unified services externally. The cluster consists of multiple nodes, including master nodes and slave nodes. For a cluster without a central master node, each master node in the cluster has the same status in the entire cluster, and each master node can be responsible for processing a part of clients. ask. [0003] In the prior art, a cluster access system usually includes: a client and a cluster, wherein, for a cluster without a central node, the client can directly communicate with all master nodes in the cluster, that is, the client can directly access any one of the clu...

Problems solved by technology

[0004] Usually, the client can successfully access the cluster using the above methods. However, in actual applications, due to changes in actual requirements, the master nodes included in the cluster may not meet the actual needs, and it is necessary to increase the master nodes to expand the cluster.

After the cluster is expanded, it may affect the client's access to the cluster. Generally, the client needs to be adjusted accordingly to adapt to the expansion of the cluster. The number of clients that can access the cluster is usually large and widely distributed. Therefore, the client The adjustment of the terminal has a wide range of influences, which increases the difficulty of expanding the cluster
