applications have a limit on the number of CPUs that can be used. The server acts as a separate entity, which is a single point of failure in the solution. If only one server is responsible for passing the functionality of the component within the application, its failure can cause the application to fail. Adding servers increases the complexity of managing and monitoring server hardware and its associated software. Solution SolutionsInstall services or applications on more than on

Distributed Database computing involves distributed transactions, data distribution, and data convergence computing. Distributed Databases can achieve high security, high performance, high availability, and other features. Of course, they also bring high costs (fixed costs and operational costs ), we analyze the design ideas from the implementation of MongoDB and MySQL Cluster to abstract some design methods that we can reference when designing databa

It is not enough to have a single node cluster. We need to add more nodes, more nodes, and more nodes! (In fact, no more than 2 ). 1) add the second node Start node1. If node1 is not added to the myad. Local Domain, add it. For more information about how to add a computer to a domain, find a solution.On node1, use clusteradmin to log on (the administrator can also use the clusteradmin account when adding the domain ).
