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；
eSiteGroup站群管理系统是基于eFramework低代码开发平台构建，是一款高度灵活、可扩展的智能化站群管理解决方案，全面支持SQL Server、SQLite、MySQL、Oracle等主流数据库，适配企业级高并发、轻量级本地化、云端分布式等多种部署场景。通过可视化建模与模块化设计，系统可实现多站点的快速搭建、跨平台协同管理及数据智能分析，满足政府、企业、教育机构等组织对多站点统一管控的
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。

ubuntu@ubuntu:~$ cat /etc/mysql/my.cnf
#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - “/etc/mysql/my.cnf” to set global options,
# - “~/.my.cnf” to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with –help to get a list of available options and with
# –print-defaults to see which it would actually understand and use.
#
# For explanations see
#
# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain “#” chars…
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.
