Mysql cluster安装说明

一、     说明

本文档介绍了如何规划、安装、配置和运行MySQL集群的基本知识。

二、     Mysql集群结构图


三、     名词解释

管理节点:这类节点的作用是管理MySQL簇内的其他节点,如提供配置数据、启动并停止节点、运行备份等。由于这类节点负责管理其他节点的配置,应在启动其他节点之前首先启动这类节点。

数据节点:这类节点用于保存簇的数据。数据节点的数目与副本的数目相关,是片段的倍数。例如,对于两个副本,每个副本有两个片段,那么就有4个数据节点。没有必要有一个以上的副本。数据节点是用命令ndbd启动的。

SQL节点:这是用来访问簇数据的节点。对于MySQL簇,客户端节点是使用NDB簇存储引擎的传统MySQL服务器。

注意:NoOfReplicas的数字要和数据节点的数量一样!

2.     数据节点安装

上传MySQL-Cluster-gpl-storage-7.1.29-1.rhel5.x86_64.rpm分别到服务器192.168.10.20和192.168.10.40上

执行

[root@192.168.10.20]# rpm -ivh MySQL-Cluster-gpl-storage-7.1.29-1.rhel5.x86_64.rpm
输出如下成功
Preparing...                ########################################### [100%]
   1:MySQL-Cluster-gpl-stora########################################### [100%]
[root@192.168.10.20]# mkdir /var/lib/mysql-data

MySQL-Cluster-gpl-server-7.1.29-1.rhel5.x86_64.rpm分别到服务器192.168.10.30和192.168.10.50上

执行

[root@192.168.10.30]#rpm -ivh MySQL-Cluster-gpl-server-7.1.29-1.rhel5.x86_64.rpm
输出如下成功
Preparing...                ########################################### [100%]
   1:MySQL-Cluster-gpl-serve########################################### [100%]
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'
Alternatively you can run:
/usr/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.
Please report any problems with the /usr/bin/mysqlbug script!
[root@192.168.10.30]# rpm -ivh MySQL-Cluster-gpl-client-7.1.29-1.rhel5.x86_64.rpm --nodeps –force
输出如下成功

[root@192.168.10.30]# vi /etc/my.cnf
Copy after login

修改my.cnf
[mysqld]
ndbcluster
ndb-connectstring=192.168.10.10:1186
[mysql_cluster]
ndb-connectstring=192.168.10.10:1186
Copy after login


192.168.10.50的安装同上

七、     Mysql集群启动

启动顺序为管理节点、数据节点、sql节点

1.     管理节点启动

//管理节点启动
//第一次启动
[root@192.168.10.10]# ndb_mgmd -f /var/lib/mysql-cluster/config.ini
//以后启动
[root@192.168.10.10]# ndb_mgmd
//config.ini 修改启动
[root@192.168.10.10]# ndb_mgmd -f /var/lib/mysql-cluster/config.ini
//启动成功为:
MySQL Cluster Management Server mysql-5.1.72 ndb-7.1.29
//查看状态
[root@192.168.10.10]# ndb_mgm
ndb_mgm>show
如下信息,各个节点的状态
[ndbd(NDB)]     2 node(s)
id=2    @192.168.10.20  (mysql-5.1.72 ndb-7.1.29, Nodegroup: 0, *)
id=4    @192.168.10.40  (mysql-5.1.72 ndb-7.1.29, Nodegroup: 0)
[ndb_mgmd(MGM)] 1 node(s)
id=1    @192.168.10.10  (mysql-5.1.72 ndb-7.1.29)
[mysqld(API)]   2 node(s)
id=3 (not connected, accepting connect from 192.168.10.30)
id=5 (not connected, accepting connect from 192.168.10.50)
Copy after login


2.     数据节点启动

//数据节点启动 第一个数据节点启动时用 –initial其它不需要
[root@192.168.10.20]# ndbd –initial 
//输出如下成功
2013-12-25 23:36:23 [ndbd] INFO     -- Angel connected to '192.168.10.10:1186'
2013-12-25 23:36:23 [ndbd] INFO     -- Angel allocated nodeid: 2
Copy after login

192.168.10.40 操作同上

3.     Sql节点启动

//sql节点启动 
[root@192.168.10.20]# mysqld_safe
//输出如下成功
131226 01:02:43 mysqld_safe Logging to '/var/lib/mysql/localhost.localdomain.err'.
131226 01:02:43 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
Copy after login

192.168.10.50 操作同上

如果启动出现如下提示


//sql节点启动
131226 01:01:50 mysqld_safe Logging to '/var/lib/mysql/localhost.localdomain.err'.
131226 01:01:51 mysqld_safe A mysqld process already exists
Copy after login

手动杀掉mysql的进程重新启动

八、     验证


在其中一个sql节点上建一个库,并建立一个测试表插入数据,再从另外一个sql节点登陆看是否同步,如果同步成功,否则失败。

九、     关闭集群


1.关闭管理节点和数据节点,只需要在管理节点里执行:

[root@192.168.10.10]# ndb_mgm -e shutdown
Node 2: Cluster shutdown initiated
Node 4: Cluster shutdown initiated
Node 4: Node shutdown completed.
Node 2: Node shutdown completed.
3 NDB Cluster node(s) have shutdown.
Disconnecting to allow management server to shutdown.
Copy after login



 2.然后关闭Sql节点,分别在2个节点里运行:

[root@192.168.10.30]# service mysql stop
Copy after login


十、     重要说明

1.在建表的时候一定要用ENGINE=NDB或ENGINE=NDBCLUSTER指定使用NDB集群存储引擎,或用ALTERTABLE选项更改表的存储引擎。
2.NDB表必须有一个主键,因此创建表的时候必须定义主键,否则NDB存储引擎将自动生成隐含的主键。
3.Sql节点的用户权限表仍然采用MYISAM存储引擎保存的,所以在一个Sql节点创建的MySql用户只能访问这个节点,如果要用同样的用户访问别的Sql节点,需要在对应的Sql节点追加用户。


十一、     其它

先看看都安装了什么包:

如果安装过程中出现错误,删除重新装

rpm -qa|grep MySQL

然后把这些包都卸载掉

rpm -e MySQL-server*

rpm -e MySQL-client*

The relationship between mysql user and database The relationship between mysql user and database Apr 08, 2025 pm 07:15 PM

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.
