【mysql集群】mysql集群配置,本人已测试
一下安装过程本人已经测试,准确的,如有问题,请Q我:420332292

在网上找这样的资料挺难找的,哥也是找了2天才找到一份比较不错的教程,悲剧哇

 MySql-Cluster安装

系统 centos5.1 32位(如何是64位下相应64位的rpm包)

http://dev.mysql.com/get/Downloads/MySQL-Cluster-7.0和下面的包名对应

一共有5个包:

MySQL-Cluster-gpl-client-7.1.3-1.rhel5.i386.rpm

MySQL-Cluster-gpl-management-7.1.3-1.rhel5.i386.rpm

MySQL-Cluster-gpl-server-7.1.3-1.rhel5.i386.rpm

MySQL-Cluster-gpl-storage-7.1.3-1.rhel5.i386.rpm

MySQL-Cluster-gpl-tools-7.1.3-1.rhel5.i386.rpm

 

3台centos 服务器:

管理节点(ndb_mgmd):192.168.1.14

 

SQL节点1(mysqld): 192.168.1.15

SQL节点1(mysqld): 192.168.1.11

 

数据节点(ndbd): 192.168.1.15

数据节点(ndbd): 192.168.1.11



  

 

//------------------------------以这个开始(七台机子都这个操做)

首先要做的是把这七台机子的防火墙关掉(如何不关的话每个节点都连不通)

 

关闭防火墙:

Service iptables stop;

Flushing firewall rules: [ OK ]

Setting chains to policy ACCEPT: filter [ OK ]

Unloading iptables modules: [ OK ]

如何这样关闭成功; 

 

创建文件夹:

存储节点:mkdir /var/lib/mysql/data  

管理结点:mkdir /var/lib/mysql-cluster  

Sql结点:要不要都行  

 

给两个文件赋权限:

chmod -R 1777 /var/lib/mysql

chmod -R 1777 /var/lib/ mysql-cluster  

//------------------------------以这个结束

 

管理节点安装:

MySQL-Cluster-gpl-management-7.0.9-0.rhel4.x86_64.rpm;

MySQL-Cluster-gpl-tools-7.0.9-0.rhel4.x86_64.rpm;

Rpm –ivh MySQL-Cluster-gpl-management-7.0.9-0.rhel4.x86_64.rpm

Rpm –ivh MySQL-Cluster-gpl-tools-7.0.9-0.rhel4.x86_64.rpm

 

vi /var/lib/mysql-cluster/config.ini

 

[ndbd default]

NoOfReplicas=2

DataMemory=80M

IndexMemory=18M

[tcp default]

SendBufferMemory=2M

ReceiveBufferMemory=2M

[NDB_MGMD DEFAULT]

PortNumber=1186

Datadir=/var/lib/mysql-cluster

[ndb_mgmd]

Id=1

HostName= 192.168.1.14

[ndbd]

Id=2

HostName=192.168.1.15

datadir=/var/lib/mysql/data

[ndbd]

Id=3

HostName= 192.168.1.11

datadir=/var/lib/mysql/data

[mysqld]

Id=14

HostName=192.168.1.15

[mysqld]

Id=15

HostName=192.168.1.11

[mysqld]

Id=16

 

//启动管理节点
ndb_mgmd -f /var/lib/mysql-cluster/config.ini

/*********************以上是安装管理节点**************************/

 

 

存储节点安装

MySQL-Cluster-gpl-storage-7.0.9-0.rhel4.x86_64.rpm

Rpm –ivh MySQL-Cluster-gpl-storage-7.0.9-0.rhel4.x86_64.rpm

vi /etc/my.cnf //确认添加修改了如下部分
[mysqld]
max_connections = 100
slow_query_log = /var/lib/mysql-cluster/slow_query.log
long_query_time = 1
datadir = /var/lib/mysql-cluster
ndbcluster
ndb-connectstring=192.168.1.14

[mysql_cluster]
ndb-connectstring= 192.168.1.14

 

初始化启动数据节点的数据库,
注意://ndbd –initial 不能同时在所有数据节点机器上执行,否者会删除所有数据.即该命令只能在其中一台数据节点中执行
ndbd –initial

 

如何这样:

[ndbd] INFO -- Configuration fetched from '10.50.8.8:1186', generation: 1

 

sql节点的安装:

MySQL-Cluster-gpl-client-7.0.9-0.rhel4.x86_64.rpm

MySQL-Cluster-gpl-server-7.0.9-0.rhel4.x86_64.rpm

 

Rpm –ivh MySQL-Cluster-gpl-server-7.0.9-0.rhel4.x86_64.rpm

Rpm –ivh MySQL-C
