The MySQL version in Ubuntu 8.04 is 5.0.51a. In the package mysql-server-5.0, not only the Cluster Server Manager (ndb_mgmd) is carried, but also the cluster management client (ndb_mgm ). The client ndb_mgm can be used to display the cluster status, so that you can understand the working status of the cluster. In this section, we install and configure the mysql-mgm.mytest.com (192.168.1.10 ). Install MySQL On the mysql-mgm.mytest.com server, install the MySQL server: $ Sudo apt-get update instal

Introduction MySQL-Cluster is a technology that allows you to deploy "in memory" database clusters in a non-shared system. Without a shared architecture, the system can use cheap hardware without special requirements for hardware and software. In addition, each component has its own memory and disk, so there is no single point of fail

Install and configure MySQL Cluster in Ubuntu I. Introduction to MySQL-Cluster MySQL Cluster is a technology that allows the deployment of "in memory" database clusters in a non-shared system. Without a shared architecture, the system can use cheap hardware without special requirements for hardware and software. In addition, each component has its own memory and disk, so there is no single point of failure. The MySQL cluster integrates the standard MySQL server with the "in-memory" Cluster Stora

only on the other data within the cluster itself.Currently, the cluster part of MySQL cluster can be configured independently of the MySQL server. In MySQL cluster, each part of cluster is treated as a 1 node. Management (MGM) node: the role of such nodes is to manage other nodes within MySQL cluster, such as providing configuration data, starting and stopping nodes, running backups, and so on. Because such nodes are responsible for ma

features high availability and good data consistency.MySQL Cluster is able to configure the NDB storage engine with multiple failover and load balancing options, but this is easiest to do on the storage engine at the Cluster level. The NDB storage engine for MySQL cluster contains a complete set of data, depending only on the other data within the cluster itself.Currently, the cluster part of MySQL cluster can be configured independently of the MySQL server. In MySQL cluster, each part of clust
