slave node each runs one copy, and can only run on these 2 nodes.For some cluster services, the startup-related resources are sequential. For example, to start a MySQL Cluster service, you should first mount a shared storage device, or the instant MySQL service starts up, and the user cannot access the data. So, generally, we need to constrain resources. There are several types of resource constraints:(1), Position constraint (location): the degree to which a resource tends to be a node, usuall
should first mount a shared storage device, or the instant MySQL service starts up, and the user cannot access the data. So, generally, we need to constrain resources. There are several types of resource constraints:(1), Position constraint (location): the degree to which a resource tends to be a node, usually defined by a fraction (score), which indicates that the resource tends to be associated with this node when score is positive, and a negative value indicates that the resource tends to fl
