Wherein, the parameter in Data Migration script is the node resource list information comprising in the node resource list information of the application cluster that moves of request and new application cluster server cluster.That is to say, the node resource list information comprising in the node resource list information of the application cluster that request is moved and new application cluster server cluster arranges according to mapping relations coupling.
Particularly, after calling data migration script, can carry out Data Migration, wherein, the data that need to move can be to store in data memory module, like this, for the larger application cluster of data volume, can provide the effect of data relay.Religion religion ground, data memory module can provide NFS file access interface and FTP interface, in concrete enforcement, user can carry out the transfer of Data Migration by this interface of choice for use, also can adopt on the node resource of the application cluster moving in request, directly to carry out data Replica and realize Data Migration.
In concrete enforcement, after application program successful installation, the Data Migration script install_data that scheduler Automatically invoked user uploads, the parameter of this program is the node resource list for comprising in the node listing of source cluster and new application cluster server too.Data Migration script install_data is responsible between source node (node resource of the application cluster that moves of request) and destination node (node resource of new application cluster server) and carries out application migration, due to the diversity of data itself, Data Migration script install_data itself is responsible for data storage location and Data Migration mode to resolve and carry out, and the corresponding relation of the data storage of responsible source node and new node; For example, source application cluster (application cluster that request is moved) is positioned at node resource A, B, C is upper, and the node resource of new application is D, E, F(meets the node resource of being determined in idling-resource pond by scheduler of migration demand), Data Migration script install_data. can be implemented as data Replica in A in D, in B data Replica in node E, by data Replica in C in F.Its rule can be defined by Data Migration script install_data inside.Simultaneously, for adapting to the demand of large-scale data migration, this device has comprised a data memory module, provide the storage capacity of mass data as data relay, user can pass through NFS, the several data access interfaces such as FTP or object storage, deposit in migration data in this module temporarily, then are downloaded and installed by target cluster; Equally, install_data. also can pass through the mechanism such as safe copy (SCP, secure copy) and directly between node, carry out data Replica;
In concrete enforcement, scheduler calls test script test_app, and the node resource list comprising in newly assigned application cluster server cluster is passed to this test script as parameter, the result of Test Application migration, and this program is if test is by returning to 0.
Step 310, the result of application cluster migration is incorrect, be that application cluster moves failure or occurs mistake, or migration test script does not exist, need the application cluster migration success confirmation instruction of waiting for that user inputs, after receiving application cluster migration success confirmation instruction, the node resource that the application cluster of application migration is discharged is recovered in the resource pool in cloud computing platform.
