2.建立有5个节点的MySQL CLuster体系 ( OS : REDHAT 6.1 )
管理节点(MGM) 192.168.251.141
SQL节点1(SQL1) 192.168.251.141
SQL节点2(SQL2) 192.168.251.141
数据节点1(NDBD1) 192.168.251.141
数据节点2(NDBD2) 192.168.251.141
3.首先去下载文件 mysql-cluster-gpl-7.2.7-linux2.6-x86_64.tar.gz
4.解压文件到/mysqlData/ 并 重命名为 mysql-cluster
[root@dbcp-db01 mysqlData]# pwd
/mysqlData
[root@dbcp-db01 mysqlData]# ls
mysql-cluster-gpl-7.2.7-linux2.6-x86_64.tar.gz mysql-cluster
5.建立软连
ln -s /mysqlData/mysql-cluster/ /usr/local/mysql
6.在/etc/profile 加入 export PATH=$PATH:/usr/local/mysql/bin
echo “export PATH=$PATH:/usr/local/mysql/bin” >> /etc/profile
source /etc/profile
7.配置管理节点
[root@dbcp-db01 config]# vi /data/config/mysqlcluster.ini
[NDBD DEFAULT]
NoOfReplicas=1
[TCP DEFAULT]
portnumber=3388
#
[NDB_MGMD]
NodeId = 1
hostname=192.168.251.141
#
datadir=/mysqlData/clustermgmd-data/
#
[NDBD]
NodeId = 2
hostname=192.168.251.141
datadir=/mysqlData/clusterndb1-data/
#
[NDBD]
NodeId = 3
hostname=192.168.251.141
datadir=/mysqlData/clusterndb2-data/
#
[MYSQLD]
NodeId = 4
hostname=192.168.251.141
#
[MYSQLD]
NodeId = 5
hostname=192.168.251.141
[MYSQLD]
8.配置存储节点和SQL节点（配置两个cnf 配置不同的参数路径）
[root@dbcp-db01 config]# vi /data/config/my-node4.cnf
[mysqld]
ndbcluster
basedir=/mysqlData/mysql-cluster
datadir=/mysqlData/clusterndb1-data/
socket=/data/socket/my-n1.sock
pid-file=/data/socket/n1.pid
log-error = /mysqlLog/n1_err.log
slow_query_log_file = /mysqlLog/n1_slow.log
port = 3399
ndb-connectstring=192.168.251.141
[mysql_cluster]
ndb-connectstring=192.168.251.141
[root@dbcp-db01 config]# vi /data/config/my-node5.cnf
[mysqld]
ndbcluster
basedir=/mysqlData/mysql-cluster
datadir=/mysqlData/clusterndb2-data/
socket=/data/socket/my-n2.sock
pid-file=/data/socket/n2.pid
log-error = /mysqlLog/n2_err.log
slow_query_log_file = /mysqlLog/n2_slow.log
port = 3398
ndb-connectstring=192.168.251.141
[mysql_cluster]
ndb-connectstring=192.168.251.141
9.建立mysql用户组和mysql用户
groupadd mysql
useradd -g mysql mysql
10.创建配置文件中所用到的目录
mkdir -p /mysqlData/clusterndb2-data/
mkdir -p /mysqlData/clusterndb1-data/
mkdir -p /data/socket/
mkdir -p /mysqlLog/
mkdir -p /mysqlData/clustermgmd-data/
11.更改相关目录的权限
chown -R mysql.mysql /mysqlData/
chown -R mysql.mysql /mysqlLog/
12.初始化SQL节点
[root@dbcp-db01 ~]# cd /usr/local/mysql/scripts/
[root@dbcp-db01 scripts]# ./mysql_install_db --defaults-file=/data/config/my-node4.cnf --datadir=/mysqlData/clusterndb1-data/ --user=mysql --basedir=/mysqlData/mysql-cluster/ &
[1] 24447
[root@dbcp-db01 scripts]# Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/mysqlData/mysql-cluster//bin/mysqladmin -u root password ‘new-password‘
/mysqlData/mysql-cluster//bin/mysqladmin -u root -h dbcp-db01 password ‘new-password‘
Alternatively you can run:
/mysqlData/mysql-cluster//bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /mysqlData/mysql-cluster/ ; /mysqlData/mysql-cluster//bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /mysqlData/mysql-cluster//mysql-test ; perl mysql-test-run.pl
Please report any problems with the /mysqlData/mysql-cluster//scripts/mysqlbug script!
[root@dbcp-db01 ~]# cd /usr/local/mysql/scripts/
[root@dbcp-db01 scripts]# ./mysql_install_db --defaults-file=/data/config/my-node5.cnf --datadir=/mysqlData/clusterndb1-data/ --user=mysql --basedir=/mysqlData/mysql-cluster/ &

13.启动mysql-cluster，启动顺序为 管理节点->存储节点->SQL节点
A. 启动管理节点
[root@dbcp-db01 ~]# ndb_mgmd -f /data/config/mysqlcluster.ini
MySQL Cluster Management Server mysql-5.5.25 ndb-7.2.7
[root@dbcp-db01 ~]#
B. 启动存储节点
[root@dbcp-db01 scripts]# /usr/local/mysql/bin/ndbd --defaults-file=/data/config/my-node4.cnf --initial
2012-08-10 11:25:13 [ndbd] INFO -- Angel connected to ‘192.168.251.141:1186‘
2012-08-10 11:25:13 [ndbd] INFO -- Angel allocated nodeid: 2
[root@dbcp-db01 scripts]# /usr/local/mysql/bin/ndbd --defaults-file=/data/config/my-node5.cnf --initial
2012-08-10 11:25:25 [ndbd] INFO -- Angel connected to ‘192.168.251.141:1186‘
2012-08-10 11:25:25 [ndbd] INFO -- Angel allocated nodeid: 3
[root@dbcp-db01 scripts]#
C. 启动SQL节点
[root@dbcp-db01 scripts]# mysqld_safe --defaults-file=/data/config/my-node4.cnf --user=mysql &
[1] 24649
[root@dbcp-db01 scripts]# 120810 11:26:41 mysqld_safe Logging to ‘/mysqlLog/n1_err.log‘.
120810 11:26:41 mysqld_safe Starting mysqld daemon with databases from /mysqlData/clusterndb1-data/
[root@dbcp-db01 scripts]# ps aux | grep mysqld

root 24873 0.0 0.0 103152 796 pts/1 S+ 11:27 0:00 grep mysqld
[root@dbcp-db01 scripts]#
14.所有节点都启动了 用 ndb_mgm 查看
[root@dbcp-db01 ~]# ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show
Connected to Management Server at: localhost:1186

15.在SQL节点端口3399上 创建数据库，表，插入数据
[root@dbcp-db01 config]# mysql -uroot -p -S /data/socket/my-n1.sock
Enter password:
