下载到/home/weijianzhongwj/software下

2.安装mysql cluster

cd /home/weijianzhongwj/software

tar xvf mysql-cluster-gpl-7.2.8-linux2.6-i686.tar.gz

ln -s mysql-cluster-gpl-7.2.8-linux2.6-i686 mysqlc

在$HOME/.bashrc增加 export PATH=$PATH:/home/weijianzhongwj/software/mysqlc/bin 一行，添加mysql的bin目录到path路径中

3.对于一个mysql集群，我们需要启动一个mysql server(mysqld),两个data nodes(NDB)，还有一个管理结点(ndb_mgmd),我们测试是在单机中，对于在多台机器上，在data nodes配置的hostname修改为对应机器的ip则可。

我们先来添加爱mysql集群需要的配置文件

先进入mysqlc的目录，在这个目录下创建配置文件目录和数据文件目录

cd /home/weijianzhongwj/software/mysqlc

mkdir my_cluster my_cluster/ndb_data my_cluster/mysqld_data my_cluster/conf

然后在my_cluster/conf中创建下面两个文件：

my.cnf

[mysqld]

ndbcluster

datadir=/home/weijianzhongwj/software/mysqlc/my_cluster/mysqld_data

basedir=/home/weijianzhongwj/software/mysqlc

port=5000

config.ini

[ndb_mgmd]

hostname=localhost

datadir=/home/weijianzhongwj/software/mysqlc/my_cluster/ndb_data

NodeId=1

[ndbd default]

noofreplicas=2

datadir=/home/weijianzhongwj/software/mysqlc/my_cluster/ndb_data

[ndbd]

hostname=localhost

NodeId=3

[ndbd]

hostname=localhost

NodeId=4

[mysqld]

NodeId=50

然后在mysqlc的目录下，创建名称为mysql数据库，这是所有mysql需要创建的数据库

cd /home/weijianzhongwj/software/mysqlc/

scripts/mysql_install_db --no-defaults --datadir=/home/weijianzhongwj/software/mysqlc//my_cluster/mysqld_data/

4.启动管理结点，数据结点，mysql server

weijianzhongwj@ubuntu:~/software/mysqlc$ bin/ndb_mgmd -f my_cluster/conf/config.ini --initial --configdir=/home/weijianzhongwj/software/mysqlc/my_cluster/conf/
