一臺主機上配置MySQL Cluster

一個管理節點 ndb_mgmd(MGM)
兩個資料節點 ndbd(NDB)
兩個SQL節點  mysqld(API)

[root@oel5 tmp]# tar xvfz mysql-cluster-gpl-7.1.4b-linux-x86_64-glibc23.tar.gz
[root@oel5 tmp]# mv mysql-cluster-gpl-7.1.4b-linux-x86_64-glibc23 mysqlc

建立資料檔案目錄：
[root@oel5 /]# cd /mysqlc
[root@oel5 mysqlc]# mkdir data1
[root@oel5 mysqlc]# mkdir data2
[root@oel5 /]# chown -R mysql:dba mysqlc/

建立cluster配置檔案：
[root@oel5 mysqlc]# vi config.ini
-----------------------------------------
[NDBD DEFAULT]
NoOfReplicas: 2
[MGM DEFAULT]
PortNumber: 1186
[NDB_MGMD]
Id: 1
HostName: localhost
ArbitrationRank: 1
[NDBD]
Id: 2
HostName: localhost
[NDBD]
Id: 3
HostName: localhost
[mysqld]
Id: 5
HostName: localhost
[mysqld]
Id: 6
HostName: localhost
-----------------------------------------

初始化管理節點（ndb_mgmd）：
[root@oel5 /]# cd /mysqlc
[root@oel5 mysqlc]# bin/ndb_mgmd --initial -f config.ini --configdir=/mysqlc
2010-07-27 09:42:49 [MgmtSrvr] INFO     -- NDB Cluster Management Server. mysql-5.1.44 ndb-7.1.4b
2010-07-27 09:42:49 [MgmtSrvr] INFO     -- Reading cluster configuration from 'config.ini'

初始化資料節點（ndbd）：
[root@oel5 mysqlc]# bin/ndbd --initial -c localhost:1186
2010-07-27 09:47:42 [ndbd] INFO     -- Configuration fetched from 'localhost:1186', generation: 1
[root@oel5 mysqlc]# bin/ndbd --initial -c localhost:1186
2010-07-27 09:48:32 [ndbd] INFO     -- Configuration fetched from 'localhost:1186', generation: 1

建立兩個mysqld(API)節點配置檔案：
[root@oel5 mysqlc]# vi my1.cnf
-----------------------------------------
[mysqld]
ndb-nodeid=5
ndbcluster
port            = 9306
datadir = /mysqlc/data1
basedir = /mysqlc
server-id = 1
log-bin
socket = /tmp/mysql5.sock
-----------------------------------------

[root@oel5 mysqlc]# vi my2.cnf
-----------------------------------------
[mysqld]
ndb-nodeid=6
ndbcluster
port            = 9307
datadir = /mysqlc/data2
basedir = /mysqlc
server-id = 2
log-bin
socket = /tmp/mysql6.sock
-----------------------------------------

初始化mysqld(API)節點：
[root@oel5 mysqlc]# scripts/mysql_install_db --basedir=/mysqlc --datadir=/mysqlc/data1
[root@oel5 mysqlc]# scripts/mysql_install_db --basedir=/mysqlc --datadir=/mysqlc/data2

啟動mysqld(API)節點：
