简介
[说明本次部署的内容，目的等等]
本部署文档的目的是如何在ubuntu server上进行mysql的群集部署。
前期准备在进行本文档操作前，，需要完成如下前期步骤：
1. 安装3台ubuntu server服务器；
server1: ndbd 192.168.68.5
server2: ndbd 192.168.68.6
server3: mysqld –ndb-cluster 192.168.68.8
ndbd（192.168.68.5\192.168.68.6）： 数据库节点，存放数据。
mysqld –ndb-cluster(192.168.68.8)： mysql服务器节点，管理节点，管理群集。
注：
本实验在ubuntu server （8.04）实现
管理节点:server3(192.168.68.8)存储节点:server1(192.168.68.5),server2(192.168.68.6)
2. 3台server均安装mysql - server数据库。
部署概要1. 安装ubuntu服务器（本实验使用为8.04）；
2. 安装mysql – server数据库；
3. 这三台服务器上配置my.cnf；
4. 管理节点（192.168.68.8）上配置ndb_mgmd.cnf；
5. 管理节点服务器上启动mysql-ndb-mgm；
6. 存储节点上（192.168.68.5\6）启动mysql-ndb；
7. 3台服务器分别启动mysql-ndb服务；
8. 测试管理节点。
部署步骤安装ubuntu服务器1. 安装ubuntu服务器，安装过程中安装msyql（也可单独安装）、openssh服务。
群集配置1. 在三台服务器上配置my.cnf，三台服务器都要配置。

# run program with –help to get a list of available options and with
# –print-defaults to see which it would actually understand and use.
