Can Windows configure MysqlCluster on a single computer?

Before you install MySQL Cluster, you need to uninstall your original single-node, and the installation of MySQL Clsizer is generally multi-node, with management nodes, data nodes and SQL nodes. If you install a pair of computers, you can only install the management node, data node and sql node together, and then add new computers to the cluster later.

Still won't work. Mine is win7 system, install , call for help so use netstat (such as netstat -a) under cmd to see, there are no processes occupying 3306

MySQL can open multiple libraries and users.

Galaera Cluster for MySQL is a multi-master MySQL cluster solution based on synchronous replication, which is simple to use, has no single point of failure, high availability, and can well ensure the security of our data and the expansion of our data at any time when the business continues to grow

Synchronous replication. Multi-master server topology.

Reads and writes can be performed on any node.

Automatically rejects faulty nodes.

Automatically onboard new nodes.

True row-level concurrent replication.

The client connection is the same as the experience of operating a single MySQL database, and Galara is essentially a WSREP provider, running an API interface that relies on WSREP. The WSREP API defines a set of applications** and replication call libraries to enable transactional database synchronous writeset replication and similar applications. The aim is to achieve abstract, isolated replication from the application details.

While the primary goal of this interface is authentication-based multi-master replication, the same applies to both asynchronous and synchronous master-slave replication.

I don't understand what you mean, if you want to create three independent clusters, no, the cluster of the cluster is mainly divided into three parts, management nodes, computing nodes, storage nodes, in which all management operations are carried out on the management node, if you already have a cluster, there is a database under the cluster, creating a new database is just adding two instances to the database (oracle name, instance), not creating two new clusters.

If you want to create a new cluster, you must ensure that there are new management nodes, compute nodes, and storage nodes. Here is a suggestion for you, try not to put the database of multiple projects under the same cluster, it is very troublesome, our company's project is due to the shortage of resources of Party A, there is no way, three projects use a cluster cluster, as long as one of the projects uses too large database resources, it will affect the three projects together.

Therefore, if the resources are sufficient, try to split them into multiple clusters.

mysql-cluster can be used in a production environment.

MySQL Cluster is a set of independent distributed data storage high-availability products, in fact, many people do not have the test conditions of MySQL Cluster, and it is not simple to build functions and use them.

mysqlcluster mainly solves two problems, one is the scalability problem of writing, and the other is the high availability brought by distributed data storage, which can be reached; The latest release of MySQL

In a certain hardware and network environment, the test indicators of the cluster can reach: 1 billion query minutes, 100 million modification minutes, and the performance is still very strong. But you should know that to complete such a test, not only a database server with large memory, but also a 10 Gigabit network card may be required, otherwise the test will be meaningless.

MySQL Cluster is a technology that allows clusters of "in-memory" databases to be deployed in shared-nothing systems. With a shared-nothing architecture, the system is able to use inexpensive hardware with no special hardware or software requirements. In addition, since each component has its own memory and disk, there is no single point of failure.

A MySQL Cluster consists of a group of computers, each running a variety of processes, including a MySQL server, an NDB cluster's data nodes, a management server, and (possibly) specialized data access programs. About the relationship between these components in a cluster.

If there is a single database, how to solve the single point of failure?

A single database, how to withstand the pressure of concurrency.

How to synchronize data without multiple databases of cluster.

If you deal with the above problems, you can use a single database.

MySQL Cluster solves the above problems and can be used in production.
