MySQLCluster是sharednothing分布式架构,ndb存储引擎把数据放置于内存中。可以做到无单点故障。由运行于不同服务器上的的多种进程构成,组件包括SQL节点,NDBD数据节点,管理程序,以及(可能的)数据访问程序。
表(结构)存在SQL节点中。应用程序通过SQL节点访问这些数据表;NDBD数据节点用于保存数据;集群管理通过管理工具ndb_mgmd管理。
MySQLCluster具有高可用性、高性能和可缩放性的Cluster数据管理。关于Cluster中组件的关系可见下图:

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h myqClter1 password 'new-password'
Alternatively you can run:
./bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems at http://bugs.mysql.com/
The latest information about MySQL is available on the web at
http://www.mysql.com
Support MySQL by buying support/licenses at http://shop.mysql.com
New default config file was created as ./my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings

简单测试:
使用mysql cluster中需要注意两点:
一是表必须用ENGINE=NDB或ENGINE=NDBCLUSTER选项创建,使用ALTER TABLE选项更改也可以,以使用NDB Cluster存储引擎在 Cluster内复制它们。
二是每个NDB表必须要有一个主键,如果没有,NDB Cluster存储引擎将自动生成隐含主键。
连到sql节点1上,创建ndb引擎数据表beigang,插入数据,连到sql节点2上,查看beigang表数据,再插入数据,连到sql节点1查看,没问题就OK了。
连接sql节点1,创建下表并插入数据:
