Network access method of newly added node in distributed coordination system, device and system

Abstract

The embodiment of the invention provides a network access method of a newly added node in a distributed coordination system, a device and a system. The network access method of the newly added node in the distributed coordination system provided by the invention comprises that a main node receives a network access request message sent by a new network access node, wherein the network access request message comprises the IP address of the new network access node; a first node identity is distributed to the new network access node according to the network access request message; a first corresponding relation is added in the configuration file of the main node, wherein the first corresponding relation comprises the first node identity and the IP address of the new network access node; the main node adds the first corresponding relation in a node information set so as to obtain an updated node information set; the main node sends the first node identity and the updated node information set to the new network access node, therefore, the new network access node can generates the configuration file of the new network access node according to the first node identity and the updated node information set; and the new network access node can join the distributed coordination system. The embodiment of the invention is relatively high in efficiency and simple and convenient in operation.

Description

technical field [0001] The embodiments of the present invention relate to computer technology, and in particular to a network access method, device and system for newly added nodes in a distributed coordination system. Background technique [0002] ZooKeeper can provide open source distributed configuration services, synchronization services, and naming registration for large-scale distributed computing, and provides users with easy-to-use interfaces and systems with high performance and stable functions. ZooKeeper can be used for data publishing and subscription (configuration center), cluster node election (Leaderelection), load balancing, naming service (NamingService), distributed notification / coordination, distributed locks, distributed queues, etc. [0003] Suppose there are three ZooKeeper servers in the ZooKeeper network, which are server 1, server 2 and server 3. When adding a new ZooKeeper server 4, the current process is as follows: [0004] 1. Set the node ID of...
