Problems solved by technology
When the IP address of the node changes (for example, if the router is replaced, the IPs of all nodes will change; or after a long time of offline restart, the IP address obtained from DHCP will become outdated, and a new IP address will be obtained again), because there is no redundant The remaining nodes are equivalent to node damage, the system reliability is poor, and the administrator needs to reconfigure the network
Especially when the entire network environment changes, causing the IP addresses of all nodes to change, the recovery operation is quite cumbersome
[0004] This reduces the system stability of the distributed agent management system, increases the workload of the administrator, and increases the maintenance cost

Embodiment Construction
[0034] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0035] As shown in Figure 1, the network environment change adaptive system of the distributed agent management system of this embodiment includes a network management module NetworkManager, a master node broadcast module MasterBroadcaster, a master node discovery module MasterDiscover, and a slave node synchronization configuration module SyncClient.
[0036] These modules work differently in master and slave nodes.
[0037] There is only one master node in a distributed agent management system, and the rest are slave nodes. Only the master node has the permission to write the configuration, and the slave node can only synchronize the configuration from the master node. When the network environment changes, the master node is responsible for modifying the configuration...

The invention discloses a network environment change self-adaptive method of a distributed agent management system, including: the working steps of the master node: when the network environment changes, the master node revises the configuration of the machine, and regularly sends a broadcast with the master node information to Each slave node; listen to other broadcasts at the same time. If a master node broadcast with a higher version number is found, the master node will be automatically switched to a slave node; the working steps of the slave node: connect to the master node and update as the master node changes information Configuration; when unable to connect with the master node for more than the preset time, enter the master node discovery step; master node discovery step: the slave node cyclically monitors the broadcast until it receives the broadcast from the master node and successfully connects to the master node, and then updates the configuration. When the network environment changes, the self-adapting method of the invention can automatically adapt to the changes of the network IP address, etc., so as to improve the reliability of the system and reduce the burden of management personnel.
Description
technical field [0001] The invention relates to the field of agent management, in particular to a network environment change adaptive method and system of a distributed agent management system. Background technique [0002] For a general distributed system, in order to improve reliability, each service of the distributed system has multiple redundant nodes. When a node is abnormal (for example, the IP address changes), other redundant nodes can still provide services. [0003] But for the distributed agent management system, each node has its own purpose, and redundant nodes are not designed. When the IP address of the node changes (for example, if the router is replaced, the IP addresses of all nodes will change; or if it is restarted offline for a long time, the IP address obtained from DHCP will become outdated, and a new IP address will be obtained again), because there is no redundant The remaining nodes are equivalent to node damage, and the system reliability is poo...
