./configure --prefix=/usr/local/mysql/ --with-charset=utf8 --with-collation=utf8_general_ci --with-client-ldflags=-all-static -with-mysqld-ldflags=-all-static --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-unix-socket-path=/tmp/mysql.sock --sysconfdir=/usr/local/mysql/etc --without-debug --with-mysqld-user=mysql --with-plugin=innobase --with-plugin-ndbcluster --with-plugin-partition
make
make install
cd /usr/local/mysql
mkdir mysql-cluster
cd mysql-cluster
vim config.ini

[ndbd default]
NoOfReplicas= 2
[MYSQLD DEFAULT]
[ndb_mgmd default]
DataDir= /usr/local/mysql/mysql-cluster
[ndb_mgmd]
HostName= www.bkjia.com
[ndbd]
HostName= 192.168.6.160
DataDir= /usr/local/mysql/mysql-cluster
[ndbd]
HostName= 192.168.6.188
DataDir= /usr/local/mysql/mysql-cluster
[mysqld]
HostName= 192.168.6.160
[mysqld]
HostName= 192.168.6.188
[mysqld]
HostName= 192.168.6.191/usr/local/mysql/libexec/ndb_mgmd -f /usr/local/mysql/mysql-cluster/config.ini/usr/local/mysql/bin/ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show
Connected to Management Server at: localhost:1186
Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=2 (not connected, accepting connect from 192.168.6.160)
id=3 (not connected, accepting connect from 192.168.6.188)

[ndb_mgmd(MGM)] 1 node(s)
id=1 @www.bkjia.com (Version: 5.1.45)

[mysqld(API)] 3 node(s)
id=4 (not connected, accepting connect from 192.168.6.160)
id=5 (not connected, accepting connect from 192.168.6.188)
id=6 (not connected, accepting connect from 192.168.6.191)可以看到ndb_mgmd 是 连上的，nbd 和 mysqld 还没有连上~

二.在两个ndbd 节点 DB1,DB2 安装mysql

./configure --prefix=/usr/local/mysql/ --with-charset=utf8 --with-collation=utf8_general_ci --with-client-ldflags=-all-static -with-mysqld-ldflags=-all-static --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-unix-socket-path=/tmp/mysql.sock --sysconfdir=/usr/local/mysql/etc --without-debug --with-mysqld-user=mysql --with-plugin=innobase --with-plugin-ndbcluster --with-plugin-partition

groupadd mysql
useradd -g mysql mysql
cd /usr/local/mysql
chown root.mysql . -R
/usr/local/mysql/bin/mysql_install_db --user=mysql

vim /usr/local/mysql/etc/my.cnf
[mysqld]
basedir = /usr/local/mysql/
datadir = /usr/local/mysql/var
user = mysql
port = 3306
socket = /tmp/mysql.sock
ndbcluster
ndb-connectstring=www.bkjia.com
[mysql_cluster]
ndb-connectstring=www.bkjia.com/usr/local/mysql/libexec/ndbd --initial ### 第一次启动需要 --initial 以后在启动不需要加随后启动两台ndbd 节点上的 mysql 服务

/usr/local/mysql/bin/mysqld_safe --user=mysql &然后在 MGM 服务器上查看

/usr/local/mysql/bin/ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show
Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=2 @192.168.6.160 (Version: 5.1.45, Nodegroup: 0)
id=3 @192.168.6.188 (Version: 5.1.45, Nodegroup: 0, Master)
[ndb_mgmd(MGM)] 1 node(s)
id=1 @www.bkjia.com (Version: 5.1.45)
[mysqld(API)] 3 node(s)
id=4 @192.168.6.160 (Version: 5.1.45)
id=5 @192.168.6.188 (Version: 5.1.45)
id=6 (not connected, accepting connect from 192.168.6.191)从上面可以看出 两个 ndbd 节点 和 ndbd 上的两个mysql 服务已经连接上了。
三.DB4安装mysql节点

./configure --prefix=/usr/local/mysql/ --with-charset=utf8 --with-collation=utf8_general_ci --with-client-ldflags=-all-static -with-mysqld-ldflags=-all-static --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-unix-socket-path=/tmp/mysql.sock --sysconfdir=/usr/local/mysql/etc --without-debug --with-mysqld-user=mysql --with-plugin=innobase --with-plugin-ndbcluster --with-plugin-partition
groupadd mysql
useradd -g mysql mysql
cd /usr/local/mysql
chown root.mysql . -R
/usr/local/mysql/bin/mysql_install_db --user=mysql
vim /usr/local/mysql/etc/my.cnf
[mysqld]
basedir = /usr/local/mysql/
datadir = /usr/local/mysql/var
user = mysql
port = 3306
socket = /tmp/mysql.sock
ndbcluster
ndb-connectstring=www.bkjia.com
[mysql_cluster]
ndb-connectstring=www.bkjia.com启动 mysql 服务

/usr/local/mysql/bin/mysqld_safe --user=mysql &回到 MGM 上查看是否正常

DB1 $> /usr/local/mysql/bin/ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show
Connected to Management Server at: localhost:1186
Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=2 @192.168.6.160 (Version: 5.1.45, Nodegroup: 0)
id=3 @192.168.6.188 (Version: 5.1.45, Nodegroup: 0, Master)
[ndb_mgmd(MGM)] 1 node(s)
id=1 @www.bkjia.com (Version: 5.1.45)
[mysqld(API)] 3 node(s)
id=4 @192.168.6.160 (Version: 5.1.45)
id=5 @192.168.6.188 (Version: 5.1.45)
id=6 @192.168.6.191 (Version: 5.1.45)好了，一切正常了，现在回到 mysql 节点上 创建和删除数据看是否同步。
那么就登录 DB2 的 mysql

DB2 $> /usr/local/mysql/bin/mysql -uroot -p
Mysql >show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
+--------------------+
2 rows in set (0.00 sec)
Mysql > create database eric;
Query OK, 1 row affected (0.39 sec)
Mysql >show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| eric |
| mysql |
+--------------------+
3 rows in set (0.01 sec)好了，在看 DB3 DB4 上是否同步

Db3 $> /usr/local/mysql/bin/mysql -uroot -p
Mysql $> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| eric |
| mysql |
+--------------------+DB4 $> /usr/local/mysql/bin/mysql -uroot -p
Mysql $> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| eric |
| mysql |
+--------------------+

都看到了 eric 数据库·结束
