----------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 \
--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

# 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

mysql > show databases;

mysql> show databases;
+--------------------+
| 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 -A

Database 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)
