月归档：七月 2011

一、整体规划
192.168.11.10（ndb）
192.168.11.11（ndb）
192.168.11.12（mgm）
192.168.11.13（sql）
192.168.11.14（sql）

二、安装mysql-cluster软件(root)
所有节点相同操作，如果没有mysql用户请创建mysql用户和组
groupadd mysql
useradd -g mysql mysql

上传至/tmp目录，开始解压安装
cd/tmp
tarxzvftarxzvfmysql-cluster-gpl-7.1.15-linux-x86_64-glibc23.tar.gz
mvmysql-cluster-gpl-7.1.15-linux-x86_64-glibc23/opt/mysql_cluster
chownmysql.mysql-R/opt/mysql_cluster

三、管理节点（mgm）配置(mysql)
配置mgm节点的config.ini文件
[NDBDDEFAULT]
NoOfReplicas=2
[NDB_MGMD]
NodeId=1
hostname=192.168.11.12
[NDBD]
NodeId=11
hostname=192.168.11.11
datadir=/opt/mysql_cluster/ndbdata
[NDBD]
NodeId=12
hostname=192.168.11.10
datadir=/opt/mysql_cluster/ndbdata
[MYSQLD]
NodeId=21
hostname=192.168.11.13
[MYSQLD]
NodeId=22
hostname=192.168.11.14

启动mgm节点
/opt/mysql_cluster/bin/ndb_mgmd -f /opt/mysql_cluster/config.ini –configdir=/opt/mysql_cluster

四、数据节点配置(mysql)
配置ndb节点参数(/opt/mysql_cluster/my.cnf)
[mysqld]
ndbcluster
ndb-connectstring=192.168.11.12
[mysql_cluster]
ndb-connectstring=192.168.11.12

创建ndbdata文件夹
mkdir /opt/mysql_cluster/ndbdata

启动ndb节点
/opt/mysql_cluster/bin/ndbd –defaults-file=/opt/mysql_cluster/my.cnf –initial

五、SQL节点配置(mysql)
初始化sql节点
/opt/mysql_cluster/scripts/mysql_install_db –user=mysql –datadir=/opt/mysql_cluster/data –basedir=/opt/mysql_cluster/

配置my.cnf文件(root)
mv /opt/mysql_cluster/my-large.cnf /etc/my.cnf
添加
[mysqld]
ndbcluster
ndb-connectstring=192.168.11.12
[mysql_cluster]
ndb-connectstring=192.168.11.12

修改mysql.server(mysql)
/opt/mysql_cluster/support-files/mysql.server中的datadir和basedir为
basedir=/opt/mysql_cluster
datadir=/opt/mysql_cluster/data

启动sql节点(mysql)
/opt/mysql_cluster/support-files/mysql.server start

六、查看集群状态(msyql)
ndb_mgm> show
Connected to Management Server at: localhost:1186
Cluster Configuration
———————
[ndbd(NDB)] 2 node(s)
id=11 @192.168.11.11 (mysql-5.1.56 ndb-7.1.15, Nodegroup: 0, Master)
id=12 @192.168.11.10 (mysql-5.1.56 ndb-7.1.15, Nodegroup: 0)

[ndb_mgmd(MGM)] 1 node(s)
id=1 @192.168.11.12 (mysql-5.1.56 ndb-7.1.15)

[mysqld(API)] 2 node(s)
id=21 @192.168.11.13 (mysql-5.1.56 ndb-7.1.15)
id=22 @192.168.11.14 (mysql-5.1.56 ndb-7.1.15)

mysql 集群配置（windows2台机器模拟）
1、环境规划
win7 192.168.1.1（管理节点，存储节点，sql节点）
win03 192.168.1.2（存储节点，sql节点）

2、安装cluster（zip包）
win7机器安装在D:\mysql-cluster中
win03机器安装在C:\mysql-cluster中
存储节点存储路径分别为：D:\mysql-cluster\ndbdata和C:\mysql-cluster\ndbdata

3、win7机器配置
创建D:\mysql-cluster\config.txt文件，内容为：
[NDBD DEFAULT]
NoOfReplicas=2
[NDB_MGMD]
ID=1
hostname=192.168.1.1
datadir=D:\mysql-cluster\data
[NDBD]
ID=21
hostname=192.168.1.1
datadir=D:\mysql-cluster\ndbdata
[NDBD]
ID=22
hostname=192.168.1.2
datadir=C:\mysql-cluster\ndbdata
[MYSQLD]
ID=11
hostname=192.168.1.1
[MYSQLD]
ID=12
hostname=192.168.1.2

复制D:\mysql-cluster\my-small.ini到c:\windows\my.ini并添加
[mysqld]
ndbcluster
ndb-connectstring=192.168.1.1
[mysql_cluster]
ndb-connectstring=192.168.1.1

4、win03机器配置
复制C:\mysql-cluster\my-small.ini到c:\windows\my.ini并添加
[mysqld]
ndbcluster
ndb-connectstring=192.168.1.1
[mysql_cluster]
ndb-connectstring=192.168.1.1

5、启动
5.1）启动管理节点(win7 上)
D:\mysql-cluster\bin>ndb_mgmd.exe –config-file=D:\mysql-cluster\config.txt –co
nfigdir=D:\mysql-cluster

5.2）启动存储节点（无先后顺序，第一个启动使用–initial)
win7
D:\mysql-cluster\bin>ndbd.exe –initial
win03
C:\mysql-cluster\bin>ndbd.exe

5.3）启动sql节点（无先后顺序）
win03
C:\mysql-cluster\bin>mysqld.exe –defaults-file=c:\windows\my.ini
win7
d:\mysql-cluster\bin>mysqld.exe –defaults-file=c:\windows\my.ini

6、查看是否启动成功
6.1）查看状态
D:\mysql-cluster\bin>ndb_mgm.exe
– NDB Cluster — Management Client –
ndb_mgm> show
Connected to Management Server at: 192.168.1.1:1186

6.2数据操作测试
在win7上创建表，并插入数据
