Problems solved by technology
[0003] At present, the existing virtual IP allocation method above is random allocation. The virtual IP assigned to each node is random. It is impossible to predict which virtual IP each node will be assigned in advance. After the node restarts and joins the cluster, CTDB randomly selects a certain one or Multiple virtual IPs are assigned to this node, which can meet limited application scenarios, especially the application requirements for disaster recovery

The invention discloses a virtual IP distribution method. The method comprises the following steps: establishing a corresponding relationship between a virtual IP and a node and a corresponding relationship between the node and a virtual IP group; traversing the virtual IP, searching a node corresponding to the virtual IP according to a corresponding relationship between the virtual IP and the node, and judging whether the node is normal or not; if the node is an abnormal node, determining a virtual IP group to which the abnormal node belongs according to a corresponding relationship between the node and the virtual IP group, and judging whether a normal node exists in the virtual IP group or not; if so, allocating the virtual IP to a normal node in a virtual IP group to which the abnormalnode belongs; and if not, allocating the virtual IP to normal nodes in other virtual IP groups. The virtual IP distribution method can effectively meet the application requirements of disaster recovery, and improve the cluster load processing performance, stability and high availability. The invention further discloses a virtual IP distribution device and equipment and a computer readable storagemedium, which all have the above technical effects.
Description
technical field [0001] The present application relates to the technical field of distributed storage, and in particular to a virtual IP allocation method; it also relates to a virtual IP allocation device, device, and computer-readable storage medium. Background technique [0002] CTDB is a high-availability management software for clusters. During the startup process of CTDB, it will read the configured virtual IPs from the virtual IP configuration file and distribute these virtual IPs evenly and randomly to each node of the cluster according to the specified algorithm. When the cluster When one or some of the nodes fails, CTDB will perform failover, release the virtual IP allocated on the original failed node and then drift the virtual IP to other normal nodes, and the corresponding read and write services will also drift to other Normal node; when the faulty node returns to normal and joins the cluster, CTDB will randomly select virtual IPs on other nodes and assign them ...
