Cluster配置
10.152.8.130 管理节点


10.152.8.91  数据节点 sql节点
10.152.8.92 数据节点 sql节点




1、分别在三台服务器上
将Cluster安装到C盘(默认的路径下)
2、在管理节点的C盘创建
生成c:/mysql/bin、C:/mysql/mysql-cluster(第一次启动后在这个文件夹会生成类似ndb_1_config.bin.1的文件,好像是为了以后启动加载的配置)
和c:/mysql/bin/cluster-logs目录,在下载解压的文件目录mysql/bin中将ndb_mgmd.exe和ndb_mgm.exe复制到172.16.0.162的c:/mysql/bin目录下。
在管理节点服务器的c:/mysql/bin下生成两个文件,my.ini和config.ini。
my.ini的内容为:
[mysql_cluster]

config_file=c:/mysql/bin/config.ini

config.ini文件的内容为:
[NDBD DEFAULT]
NoOfReplicas=2
datadir=d:\mysqlcluster\datanode\mysql\bin\cluster-data
datamemory=1G
indexmemory=200M
[MYSQLD DEFAULT]  
[NDB_MGMD DEFAULT]  
[TCP DEFAULT]
[NDB_MGMD]
Nodeid=1
HostName=10.152.8.130
datadir=c:\mysql\bin\cluster-logs
[NDBD]
Nodeid=2
HostName=10.152.8.91
DataDir=d:\mysqlcluster\datanode\mysql\bin\cluster-data
[NDBD]
Nodeid=3
HostName=10.152.8.92
DataDir=d:\mysqlcluster\datanode\mysql\bin\cluster-data
[MYSQLD]
Nodeid=4
HostName=10.152.8.91
[MYSQLD]
Nodeid=5
HostName=10.152.8.92

2、
在所有数据节点
在D盘创建
d:\mysqlcluster\datanode\mysql\bin\cluster-data
d:\mysqlcluster\datanode\mysql\cluster-data


将安装包解压后的mysql/bin目录中的ndbd.exe拷贝到 d:\mysqlcluster\datanode\mysql\bin 下
在d:mysqlcluster\datanode\mysql\bin 下创建 my.ini文件。内容为


[mysqld]
ndbcluster
[mysql_cluster]
ndb-connectstring=10.152.8.130

3、
在所有SQL节点中 创建
d:\mysqlcluster\sqlnode


将Cluster 安装包中的mysql的目录整个拷贝到 d:\mysqlcluster\sqlnode下


修改 d:\mysqlcluster\sqlnode\mysql\my-default.ini 或在d:\mysqlcluster\sqlnode\mysql下创建 my.ini文件
内容为:
[mysqld]
ndbcluster
ndb-connectstring=10.152.8.130

4、启动集群
顺序(必须)为:
管理节点服务器 > 数据节点服务器 > SQL节点服务器
a、
启动管理节点
c:\mysql\bin\ndb_mgmd -f config.ini --configdir=c:\mysql\bin\cluster-logs
我在启动管理节点服务器的管理节点服务时遇到如下错误:
Could neither create or open key 'SYSTEM\CurrentControlSet\Services\EventLog\Application\MySQL Cluster Management Server', error: 5
Failed to setup event logging


解决方法:
regedit 打开注册表
在HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application\下新建创建KEY 值 MySQL Cluster Management Server  即可
再次执行 c:\mysql\bin\ndb_mgmd -f config.ini --configdir=c:\mysql\bin\cluster-logs
查看是否启动成功
c:\mysql\bin\ndb_mgm 
ndb_mgm>show  或者 all status


b、
启动数据节点服务
d:\mysqlcluster\datanode\mysql\bin\ndbd --connect-string="nodeid2;host=10.152.8.130:1186"
d:\mysqlcluster\datanode\mysql\bin\ndbd --connect-string="nodeid3;host=10.152.8.130:1186"


nodeid2是根据管理节点的配置文件
         config.ini中的id决定的,如果id为2,则为nodeid2
查看是否启动成功
c:\mysql\bin\ndb_mgm 
ndb_mgm>show  或者 all status


如果遇到:
Could neither create or open key 'SYSTEM\CurrentControlSet\Services\EventLog\Application\MySQL Cluster Data Node Daemon', error: 5
Failed to setup event logging
解决方法:
在HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application\下新建创建KEY 值 MySQL Cluster Data Node Daemon 即可
c、
启动SQL节点
d:\mysqlcluster\sqlnode\mysql\bin\mysqld --console
