node in our cluster. A replica set is a node for cluster. Because at any moment, only the primary in the replica set can accept the write operation. So in order to play cluster , we need to add more than one replica set so that MONGOs can read and write multiple replica sets in parallel. Refer to the replica set deployment document to create the new replica set

Setup of MySQL/MariaDB Galera cluster in Linux MariaDB Introduction MariaDB is a MySQL Branch maintained by the open-source community. It is developed by MySQL founder Michael Widenius and uses a GPL license. MariaDB is designed to be fully compatible with MySQL, including APIs and command lines, so that it can easily become a substitute for MySQL.

By moving applications on a failed server to a backup server, the cluster system can increase uptime to more than 99.9%, significantly reducing server and application downtime.High manageability: System administrators can remotely manage one or even a group of clusters as if they were in a standalone system."Disadvantage"We know that the application in the
