Login to the db2 server as root user And download MySQL Cluster package: cd ~
We use 2 CentOS servers for the SQL Nodes: This is step contains the setup for the SQL Node that provides the application access to the database. 19:35:56 INFO - Angel allocated nodeid: 2 Ndb-connectstring=172.26.87.42 # IP address of Management Node Login to the db2 server with ssh.Then download the MySQL Cluster package and extract it: cd ~
We will use 2 CentOS servers for the Data Nodes. Step 2 – Setup the MySQL Cluster Data Nodes The management node is started, now you can use command “ndb_mgm” to monitor the node: ndb_mgm 19:26:08 INFO - Successfully created config directory 19:26:08 INFO - The default config directory '/usr/mysql-cluster' does not exist. MySQL Cluster Management Server mysql-5.6.28 ndb-7.4.10 Start the Management Node ndb_mgmd -config-file=/var/lib/mysql-cluster/config.ini IndexMemory=128M # Memory allocate for index storage Rpm -Uvh MySQL-Cluster-shared-gpl-7.4.86_64.rpmĭataMemory=256M # Memory allocate for data storage Rpm -Uvh MySQL-Cluster-server-gpl-7.4.86_64.rpm Rpm -Uvh MySQL-Cluster-client-gpl-7.4.86_64.rpm Tar -xvf MySQL-Cluster-gpl-7.4.86_64.rpm-bundle.tar The interface servers that are used by the applications to connect to the database cluster. This is the layer where the process of synchronizing and data replication between nodes happens. We can create and configure new nodes, restart, delete, or backup nodes on the cluster from the management node. The Cluster management server is used to manage the other node of the cluster. Each node type will be installed on it’s own server. To implement a MySQL Cluster, we have to install three types of nodes. In the shared-nothing architecture, each of nodes has its own memory and disk, the use of shared storage such as NFS, SANs is not recommended and supported. The MySQL Cluster technology is implemented through the NDB (Network DataBase) and NDBCLUSTER storage engines and provides shared-nothing clustering and auto-sharding for MySQL database systems. MySQL Cluster is designed to provide a MySQL compatible database with high availability and low latency.
