1.配置环境; MGM:192.168.0.31 NDBD1:192.168.0.32 NDBD2:192168.0.33 SQL1:192.168.0.34 SQL2:192.168.0.30 2.软件安装 (

1.配置环境;
 MGM:192.168.0.31
 NDBD1:192.168.0.32
 NDBD2:192168.0.33
 SQL1:192.168.0.34
 SQL2:192.168.0.30
 

2.软件安装
 (一)管理节点MGM
 首先在合适的位置建立管理节点的配置文件;
 config.ini
 [ndbd default]
 NoOfReplicas=2
 DataMemory=80M
 IndexMemory=18M
 [tcp default]
 portnumber=2202
 

[ndb_mgmd]
 hostname=192.168.0.31
 datadir=/var/lib/mysql-cluster
 [ndbd]
 hostname=192.168.0.32
 datadir=/usr/local/mysql/data
 [ndbd]
 hostname=192.168.0.33
 datadir=/usr/local/mysql/data
 [mysqld]
 hostname=192.168.0.30
 [mysqld]
 hostname=192.168.0.34
 a.改变地址到/var/tmp目录下,解压mysql-cluster压缩文件,取出ndb_mdmd和ndb_mdm;
 b.改变路径为拷贝到的目录下,,并确保这两个文件可执行;
 chmod +x ndb_mgm*
 c.在/usr/local下创建mysql文件夹;
 (二)数据节点NDBD和SQL节点;
 配置数据节点NDBD和SQL节点;
 在每个SQL节点都做如下的配置,在/etc/my.cnf文件内;
 [client]
 socket=/usr/local/mysql/sock/mysql.sock
 

[mysqld]
 ndbcluster
 datadir=/usr/local/mysql
 socket=/usr/local/mysql/sock/mysql.sock
 ndb-connectstring=192.168.0.31
 #user=mysql
 # Default to using old password format for compatibility with mysql 3.x
 # clients (those using the mysqlclient10 compatibility package).
 old_passwords=1
 

# Disabling symbolic-links is recommended to prevent assorted security risks;
 # to do so, uncomment this line:
 # symbolic-links=0
 [mysql_cluster]
 ndb-connectstring=192.168.0.31
