Abstract

The invention provides a design method for improving cluster business availability by using cluster management node as two computers. In the method, a management node two-computer manner is utilized to realize uninterrupted monitoring and management on the cluster business and shield service interruption caused by single management node shutdown, so that the cluster operation management has disaster holding capability and realizes high availability. According to the design method by using management nodes as host and slave computers, data is allocated to the mirror image disks of the two computers, so that real-time synchronization of the middle business data on the host computer and slave computer is realized; the host computer provides cluster monitoring management and job submission interface, and when the host computer is shut down, the slave computer takes over the cluster business progresses in an uninterrupted manner, so that jointless migration of the exterior service is realized; and an uniform exterior service port is provided between the host computer and the slave computer.

Example Embodiment

[0021] Example
[0022] The present invention provides a design method for realizing high availability of cluster services by using management nodes as dual computers. The implementation methods include setting up mirror synchronization partitions to store intermediate business data; internal network connections to transmit synchronous data and heartbeat information; external network connections to provide dynamic migration Access the configuration interface and cluster node management interface; deploy the same application management software on the two machines, deploy the software intermediate data (database, job scheduling and other change data) to the mirror partition, set up process monitoring scripts for each application software, and Set the migration level according to the dependencies.
