集群环境
管理节点 10.0.0.19
数据节点 10.0.0.12 10.0.0.17
sql节点 10.0.0.18 10.0.0.22
添加mysql用户
groupadd mysql
useradd mysql -g mysql
安装mysql-cluster-gpl-7.3.5-linux-glibc2.5-x86_64.tar.gz
cd /home/test
tar -zxvf mysql-cluster-gpl-7.3.5-linux-glibc2.5-x86_64.tar.gz -C /usr/local
mv mysql-cluster-gpl-7.3.5-linux-glibc2.5-x86_64/ mysql
cd ../
chown -R mysql:mysql mysql/
cd mysql
./scripts/mysql_install_db --user=mysql
这个步骤所有服务器都需要执行(5台)

启动管理节点
ndb_mgmd -f /usr/local/mysql/config.ini
关闭管理节点
[root@localhost bin]#ndb_mgm
ndb_mgm> shutdowm
备注:命令行中的ndb_mgmd是mysql cluster的管理服务器，后面的-f表示后面的参数是启动的参数配置文件。
如果在启动后过了几天又添加了一个数据节点，这时修改了配置文件启动时就必须加上--initial参数，不然添加的节点不会作用在mysql cluster中。
ndb_mgmd -f /usr/local/mysql/config.ini --initial
管理节点状态
ndb_mgm> show 查看各节点情况。
ndb_mgm> all report memory 查看各数据节点使用情况
ndb_mgm>create nodegroup 3;创建数据节点分组
mysql> alter online table data_house reorganize partition; 调整分区数据
