简单步骤,分享下:
hostname IP 应用
db1 192.168.50.10 MGM db2 192.168.50.20 NDBD db3 192.168.50.30 NDBD2 db4 192.168.50.40 MYSQLD db5 192.168.50.50 MYSQLD***************************** 1.安装配置管理节点(DB1)MGM *****************************

NoOfReplicas= 2 [MYSQLD DEFAULT] [NDB_MGMD DEFAULT] DataDir= /usr/local/mysql/mysql-cluster [NDB_MGMD] HostName= 192.168.50.10 [NDBD] HostName= 192.168.50.20 DataDir= /usr/local/mysql/mysql-cluster [NDBD] HostName= 192.168.50.30 DataDir= /usr/local/mysql/mysql-cluster [MYSQLD] HostName= 192.168.50.40 [MYSQLD] HostName= 192.168.50.50----------启动cluster管理节点
在管理节点服务器上,执行以下命令启动MGM节点进程:
root# /usr/local/mysql/ndb_mgmd -f /usr/local/mysql/config.ini
必须用参数“-f”或“--config-file”告诉 ndb_mgm 配置文件所在位置,默认是在ndb_mgmd相同目录下。
------------------
# /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 192.168.50.20) id=3 (not connected, accepting connect from 192.168.50.30)[ndb_mgmd(MGM)] 1 node(s)
id=1 @192.168.50.10 (mysql-5.1.47 ndb-7.1.8)[mysqld(API)] 2 node(s)
id=4 (not connected, accepting connect from 192.168.50.40) id=5 (not connected, accepting connect from 192.168.50.50) 可以看到ndb_mgmd 是 连上的,nbd 和 mysqld 还没有连上~
****************************************
2.安装配置在两个数据节点(DB2,DB3)ndbd **************************************** # groupadd mysql # useradd -g mysql -d /usr/local/mysql/var -M mysql # tar xvzf mysql-cluster-gpl-7.1.8.tar.gz # cd mysql-cluster-gpl-7.1.8# ./configure --prefix=/usr/local/mysql/ --with-charset=utf8 --with-collation=utf8_general_ci \

# vi /usr/local/mysql/etc/my.cnf
[mysqld]
ndbcluster ndb-connectstring=192.168.50.10 [mysql_cluster] ndb-connectstring=192.168.50.10
#./libexec/ndbd --initial ### 第一次启动需要 --initial 以后在启动不需要加
2010-06-21 14:09:38 [ndbd] INFO -- Configuration fetched from '192.168.5.10:1186', generation: 1
--------------------------启动说明
--------------------------启动存储节点
在每台存储节点服务器上,如果是第一次启动ndbd进程的话,必须先执行以下命令:
root# /usr/local/mysql/libexec/ndbd --initial
注意,仅应在首次启动ndbd时,或在备份/恢复数据或配置文件发生变化后重启ndbd时使用“--initial”参数
。因为该参数会使节点删除由早期ndbd实例创建的、用于恢复的任何文件,包括用于恢复的日志文件。 如果不是第一次启动,直接运行如下命令即可:root# /usr/local/mysql/libexec/ndbd
--------------------------
然后在 MGM 服务器上查看
[root@db1 ~]# /usr/local/mysql/bin/ndb_mgm
-- NDB Cluster -- Management Client -- ndb_mgm> show Cluster Configuration --------------------- [ndbd(NDB)] 2 node(s) id=2 @192.168.50.20 (mysql-5.1.47 ndb-7.1.8, Nodegroup: 0, Master) id=3 @192.168.50.30 (mysql-5.1.47 ndb-7.1.8, Nodegroup: 0)[ndb_mgmd(MGM)] 1 node(s)
id=1 @192.168.50.10 (mysql-5.1.47 ndb-7.1.8)[mysqld(API)] 2 node(s)
id=4 (not connected, accepting connect from 192.168.50.40) id=5 (not connected, accepting connect from 192.168.50.50)从上面可以看出 两个 ndbd 节点 和 ndbd 上存储都已经连接上了。
****************************************
3、安装配置SQL节点(DB4、DB5)
****************************************
# groupadd mysql
# useradd -g mysql -d /usr/local/mysql/var -M mysql # tar xvzf mysql-cluster-gpl-7.1.8.tar.gz
# cd mysql-cluster-gpl-7.1.8
# ./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=/usr/local/mysql/tmp/mysql.sock \ --sysconfdir=/usr/local/mysql/etc --without-debug --with-mysqld-user=mysql --with-plugins=max # make # make install # cd /usr/local/mysql # mkdir mysql-cluster etc # chown root:mysql . -R # ./bin/mysql_install_db --user=mysql # vi ./etc/my.cnf[mysqld]
basedir = /usr/local/mysql/ datadir = /usr/local/mysql/var user = mysql port = 3306 socket = /usr/local/mysql/tmp/mysql.sock ndbcluster ndb-connectstring=192.168.50.10 [mysql_cluster] ndb-connectstring=192.168.50.10 启动 mysql 服务 # ./bin/mysqld_safe --user=mysql &--------------启动mysqld服务
最后,运行以下命令启动SQL节点服务器:
root# /usr/local/mysql/bin/mysqld_safe --defaults-file=/usr/local/mysql/my.cnf &
-------------- 回到 MGM 上查看是否正常
./bin/ndb_mgm
-- NDB Cluster -- Management Client --ndb_mgm> show
Cluster Configuration --------------------- [ndbd(NDB)] 2 node(s) id=2 @192.168.50.20 (mysql-5.1.47 ndb-7.1.8, Nodegroup: 0, Master) id=3 @192.168.50.30 (mysql-5.1.47 ndb-7.1.8, Nodegroup: 0)[ndb_mgmd(MGM)] 1 node(s)
id=1 @192.168.50.10 (mysql-5.1.47 ndb-7.1.8)[mysqld(API)] 2 node(s)
id=4 @192.168.50.40 (mysql-5.1.47 ndb-7.1.8) id=5 @192.168.50.50 (mysql-5.1.47 ndb-7.1.8)
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。
**************************************** 4.新建数据库测试 ****************************************那么就登录 DB4 的 mysql
DB4 # > /usr/local/mysql/bin/mysql -uroot -p
mysql > show databases;+--------------------+
| Database | +--------------------+ | information_schema | | mysql | | ndbinfo | | test | +--------------------+ 4 rows in set (0.01 sec)
mysql > create database accp;
Query OK, 1 row affected (0.39 sec) mysql > show databases;+--------------------+
| Database | +--------------------+ | information_schema | | accp | | mysql | | ndbinfo | | test | +--------------------+ 5 rows in set (0.00 sec) 看 DB5 上是否同步 DB5 # > /usr/local/mysql/bin/mysql -uroot -p mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | accp | | mysql | | ndbinfo | | test | +--------------------+ 5 rows in set (0.00 sec)DB5 # > /usr/local/mysql/bin/mysql -uroot -p

+--------------------+ | Database | +--------------------+ | information_schema | | accp | | mysql | | ndbinfo | | test | +--------------------+ 5 rows in set (0.00 sec) 都看到了 accp 数据库 安装配置完成。****************************************
5.新建表测试 ****************************************DB5上新建测试表t1
mysql> use accp; Database changed mysql> create table t1 -> ( -> sid int not null primary key, -> sno int -> ) engine=ndbcluster; Query OK, 0 rows affected (0.37 sec)mysql> insert into t1 values (101,201);
Query OK, 1 row affected (0.01 sec)mysql> select * from t1;
+-----+------+ | sid | sno | +-----+------+ | 101 | 201 | +-----+------+ 1 row in set (0.00 sec)
DB4上查看是否同步:
mysql> use accp; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -ADatabase changed
mysql> show tables; +----------------+ | Tables_in_accp | +----------------+ | t1 | +----------------+ 1 row in set (0.02 sec)mysql> select * from t1;
+-----+------+ | sid | sno | +-----+------+ | 101 | 201 | +-----+------+ 1 row in set (0.01 sec)
