Vmware workstation6.5
操作系统：Centos 5.2 （2台）
第一台：
主机名：mysql1 IP： 192.168.1.30
第二台
主机名：mysql2 IP： 192.168.1.32
软件下载安装
下载软件地址：http://dev.mysql.com/downloads/select.php?id=14
选择操作系统是RedHat Enterprise 版本
如下：
MySQL-Cluster-gpl-client-7.0.8a-0.rhel5.i386.rpm
MySQL-Cluster-gpl-debuginfo-7.0.8a-0.rhel5.i386.rpm
MySQL-Cluster-gpl-devel-7.0.8a-0.rhel5.i386.rpm
MySQL-Cluster-gpl-embedded-7.0.8a-0.rhel5.i386.rpm
MySQL-Cluster-gpl-extra-7.0.8a-0.rhel5.i386.rpm
MySQL-Cluster-gpl-management-7.0.8a-0.rhel5.i386.rpm

MySQL-Cluster-gpl-test-7.0.8a-0.rhel5.i386.rpm
MySQL-Cluster-gpl-tools-7.0.8a-0.rhel5.i386.rpm
将软件包上传到服务器
Rpm –ivh *.rpm
具体配置 在两台机器上做（同样的配置文件）
1、创建配置文件目录：（ mysql1 mysql2）
#mkdir /var/lib/mysql-cluster –p
在/var/lib/mysql-cluster 下创建集群配置文件config.ini
编辑，添加如下内容：
[NDBD DEFAULT]
NoOfReplicas=2
DataMemory=128M
IndexMemory=64M
MaxNoOfConcurrentOperations=2000000
[MYSQLD DEFAULT]
[NDB_MGMD DEFAULT]
DataDir= /var/lib/mysql-cluster
[TCP DEFAULT]
# Section for the cluster management node
[NDB_MGMD]
# IP address of the management node (this system)
ID=1
HostName= 192.168.1.30
[NDB_MGMD]
# IP address of the management node (this system)
ID=2
HostName= 192.168.1.32
# Section for the storage nodes
[NDBD]
ID=3
# IP address of the first storage node
HostName=192.168.1.30
[NDBD]
ID=4
# IP address of the second storage node
HostName=192.168.1.32
# one [MYSQLD] per storage node
[MYSQLD]
[MYSQLD]
[MYSQLD]
[MYSQLD]
[MYSQLD]
[MYSQLD]
[MYSQLD]
2、创建API文件（ mysql1 mysql2）
编辑/etc/my.cnf 添加如下内容：
[mysqld]
default-storage-engine=ndbcluster
log=queryLog
log-slow-queries=slowquerylog
max_connections = 1000
#NDBCLUSTER
ndbcluster
ndb-connectstring = 192.168.1.30,192.168.1.32
[ndb_mgm]
connect-string = 192.168.1.30,192.168.1.32
[ndbd]
connect-string = 192.168.1.30,192.168.1.32
[mysql_cluster]
ndb-connectstring= 192.168.1.30,192.168.1.32
[ndb_mgmd]
config-file=/var/lib/mysql-cluster/config.ini
集群的启动：
启动管理节点
在mysql1 上 启动管理节点
# ndb_mgmd –ndb_nodeid=1
在mysql2上启动管理节点
# ndb_mgmd –ndb_nodeid=2
第一次会有警告：
Cluster configuration warning:
arbitrator with id 1 and db node with id 3 on same host 192.168.1.30
arbitrator with id 2 and db node with id 4 on same host 192.168.1.32
Running arbitrator on the same host as a database node may
cause complete cluster shutdown in case of host failure.
是说：节点1和3，2和4的arbitrator一样，可能引起整个集群失败 这个无所谓，继续
启动NDB
在mysql1 上运行：
# ndbd –nodeid=3 –initial
在mysql2上运行：
# ndbd –nodeid=4 –iniitial
注意：在第一次启动ndb或者修改了config.ini 文件才加上-initiail 参数
查看状态：
在任意一台机器上查看：
[root@mysql1 ~]# ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show
Connected to Management Server at: 192.168.1.30:1186
Cluster Configuration
---------------------

[mysqld(API)] 9 node(s)

id=13 (not connected, accepting connect from any host)
id=14 (not connected, accepting connect from any host)
id=15 (not connected, accepting connect from any host)
看到上面的信息就正常了
启动API
在mysql1中：
#mysqld_safe –ndb_nodeid=5 –user=mysql &
在mysql2 中：
#mysqld_safe –ndb_nodeid=6 –user=mysql &
再次查看：
[root@mysql1 ~]# ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show
Connected to Management Server at: 192.168.1.30:1186
Cluster Configuration

id=13 (not connected, accepting connect from any host)
id=14 (not connected, accepting connect from any host)
id=15 (not connected, accepting connect from any host)
显示两个API节点 正常
集群测试
在mysql1中创建库
# /usr/local/mysql/bin/mysql -u root -p
mysql >create database love；
mysql > use love;
mysql > create table love (i INT)
mysql > insert into love () VALUES (1);
在mysql2上查询：
mysql > select * from love;
mysql> show tables;
+----------------+
| Tables_in_love |
+----------------+
| love |
+----------------+
1 row in set (0.03 sec)
mysql> select * from love;
+------+
| i |
+------+
| 1 |
+------+
1 row in set (0.08 sec)
已经同步：
下面我将mysql1 停掉网卡：看一下状态：
[root@mysql2 ~]# ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show
Connected to Management Server at: 192.168.1.32:1186
Cluster Configuration

id=6 @192.168.1.32 (mysql-5.1.37 ndb-7.0.8, Nodegroup: 0, Master)
[ndb_mgmd(MGM)] 2 node(s)
id=1 (not connected, accepting connect from 192.168.1.30)
id=2 @192.168.1.32 (mysql-5.1.37 ndb-7.0.8)
[mysqld(API)] 9 node(s)
id=7 (not connected, accepting connect from any host)
id=8 (not connected, accepting connect from any host)
id=9 (not connected, accepting connect from any host)
id=10 (not connected, accepting connect from any host)
id=11 (not connected, accepting connect from any host)
id=12 (not connected, accepting connect from any host)
id=13 (not connected, accepting connect from any host)
id=14 (not connected, accepting connect from any host)
id=15 (not connected, accepting connect from any host)
mysql2 对外提供服务成为主服务器
看能否查询：
mysql> select * from love;
ERROR 1296 (HY000): Got error 157 'Unknown error code' from NDBCLUSTER
mysql> select * from love;
ERROR 1296 (HY000): Got error 157 'Unknown error code' from NDBCLUSTER
暂时不能查询，出现错误：
稍等片刻再次查询，没有错误，这段时间是故障转移，时间不是很长
具体时间没计算
在mysql2 上创建 表:
mysql > create table love1 (i INT)
mysql > insert into love1 () VALUES (1);
接下来将mysql1的网卡启动
在mysql1上查询数据：
[root@mysql1 ~]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 4
Server version: 5.1.37-ndb-7.0.8a-cluster-gpl-log MySQL Cluster Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> use love;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> show tables ;
+----------------+
| Tables_in_love |
+----------------+
| love |
| love1 |
+----------------+
2 rows in set (0.01 sec)
mysql> select * from love1;
+------+
| i |
+------+
| 1 |
+------+
1 row in set (0.00 sec)
可以看到在mysql2上创建的表love2
正常运行但是mysql1成为主服务器，这个怎么改变过来，还不清楚
The end !
