At present, the principle of providing various services externally by a cloud platform is to configure a virtual machine with a proper specification according to the requirements of users, then install software in the virtual machine, create a plurality of virtual machines if the service is a clustered service, then install software in each virtual machine, then perform cluster configuration, and finally present a configured usable clustered service. The clustered service can be maintained and managed on the cloud management platform, and the service comprises starting and stopping, modifying parameters, viewing monitoring data and the like.
Generally, a clustered service generally has various roles, for example, a MySQL cluster has a master node, a standby node and a proxy node, while a Redis cluster has a master node, a standby node and a sentinel node, and the roles of the nodes are sequentially backed up or restored in order to ensure the integrity of the cluster during backup and restoration. Taking MySQL as an example, a slave node needs to be backed up first, and then a master node needs to be backed up; redis is the backup of sentinel nodes first, and then the backup of master and slave nodes. In order to implement such logic, the conventional method writes a set of logic for each service to control, which has the disadvantages of poor expansion, logic code required for each service or role, and modification of corresponding code, which is cumbersome to operate.
