配置NDB集群

//安装文件

Management节点:192.168.70.161

SQL节点:192.168.70.160

NDB-A节点:192.168.70.150

NDB-B节点:192.168.70.151

(1),server

 [root@appdb /]#groupadd mysql

 [root@appdb /]#useradd -g mysql mysql

 [root@appdb /]#rpm ivh MySQL-Cluster-gpl-server-7.0.28-1.rhel5.i386.rpm

 [root@appdb /]#rpm ivh MySQL-Cluster-gpl-client-7.0.28-1.rhel5.i386.rpm  

(2),storage

 [root@appdb /]#groupadd mysql

 [root@appdb /]#useradd -g mysql mysql

 [root@appdb /]#rpm ivh MySQL-Cluster-gpl-storage-7.0.28-1.rhel5.i386.rpm

 [root@appdb /]#rpm ivh MySQL-Cluster-gpl-client-7.0.28-1.rhel5.i386.rpm

 [root@appdb /]#rpm ivh MySQL-Cluster-gpl-tools-7.0.28-1.rhel5.i386.rpm

 

(3),management

 [root@appdb /]#groupadd mysql

 [root@appdb /]#useradd -g mysql mysql

  [root@appdb /]#rpm ivh MySQL-Cluster-gpl-management-7.0.28-1.rhel5.i386.rpm

 [root@appdb /]#rpm ivh MySQL-Cluster-gpl-client-7.0.28-1.rhel5.i386.rpm
 [root@appdb /]#rpm ivh MySQL-Cluster-gpl-extra-7.0.28-1.rhel5.i386.rpm  

 [root@appdb /]#rpm ivh MySQL-Cluster-gpl-tools-7.0.28-1.rhel5.i386.rpm

//配置文件

(1)在data节点和storage节点,都需要my.cnf配置文件。ndb-connectstring告诉节点可以找到management(管理节点),ndbcluster 告诉节点使用ndbcluster存储引擎。
(2)在management节点需要config.ini配置文件,在数据节点有多少复制维护,分配多少内存给数据和索引。怎么找到数据节点,怎么保存数据到硬盘在每个数据节点上,怎么找到数据节点。

(3)[root@appdb /]#vim /etc/my.cnf

[mysqld]
#run NDB  storage engine
ndbcluster
#location of management server
ndb-connectstring = 192.168.70.161
#options for ndbd process:
[ndb_cluster]
#location of management server
ndb-connectstring = 192.168.70.161


配置management节点,首先创建一个目录(/var/lib/mysql-cluster),然后在改目录下创建config.ini
[root@appdb /]#mkdir -pv /var/lib/mysql-cluster

[root@appdb /]#cd /var/lib/mysql-cluster/

[root@appdb /]#vim config.ini

[ndbd default]
NoOfReplicas=2
DataMemory=80M
IndexMemory=18M
[tcp default]
# TCP/IP options:
portnumber=2202
[ndb_mgmd]
# Management process options:

# Hostname or IP address of MGM node
hostname=192.168.70.161

# Directory for MGM node log files
datadir=/var/lib/mysql-cluster 
[ndbd]
# Options for data node "A":
# Hostname or IP address
hostname=192.168.70.150

# Directory for this data node's data files
datadir=/usr/local/mysql/data
[ndbd]
# Options for data node "B":

# Hostname or IP address
hostname=192.168.70.151

# Directory for this data node's data files
datadir=/usr/local/mysql/data  
[mysqld]
# SQL node options:
hostname=192.168.70.160
