一、 安装包及说明

1.1、下载地址

http://www.mysql.com/downloads/cluster/7.1.html#downloads

mysql-cluster-gpl-7.1.15-linux-x86_64-glibc23.tar.gz (200M)

1.2、环境说明

MGM:--192.168.8.20

SQL :--192.168.8.20

NDB1:--192.168.8.21

NDB1:--192.168.8.21

1.3、安装MYSQL_Cluster

在MGM管理节点、SQL节点、NDB节点执行同一操作

#:groupadd mysql

#:useradd mysql –g mysql –s /sbin/nologin

#: tar –xvf mysql-cluster-gpl-7.1.15-linux-x86_64-glibc23.tar.gz

#:mv mysql-cluster-gpl-7.1.15-linux-x86_64-glibc23 /usr/local/mysql_cluster

#:#:vim /etc/profile

MYSQL_CLUSTER=/usr/local/mysql_cluster/bin

PATH=$PATH:$HOME/bin:$MYSQL_CLUSTER

export PATH

1.4、安装MGM管理节点

#:mkdir -p /opt/mgm/logs

#:mkdir /opt/conf

#: cp /soft/mgm-conf/config.ini /opt/conf/

#:vim /opt/conf

# Options affecting ndbd processes on all home/data nodes:

[ndbd default]

NoOfReplicas=2

DataMemory=200M  # How much memory to allocate for home/data storage

IndexMemory=18M  # How much memory to allocate for index storage

                 # For DataMemory and IndexMemory, we have used the

                 # default values. Since the "world" home/database takes up

                 # only about 500KB, this should be more than enough for

                 # this example Cluster setup.

1.7、常见问题及启动顺序

启动顺序

MGM-->NDBD-->SQL

关闭顺序

关闭

SQL-->MGM (NDBD)

当关闭掉MGM后。NDBD也会停掉

关闭MGM

ndb_mgm –e shutdown

测试：

ndbd_mgm –e show
