首页 / 数据库 / MySQL / (MySQL 集群) MySQL Cluster在Linux上的安装(RedHat 5.6)

一、环境介绍
IP_AddressPort_NoNode_nameService_nameDesc
192.168.56.101  3306SQL node(API Node)mysqldSQL节点(API节点)
192.168.56.101 2202Data Nodendbd数据节点
192.168.56.102 3306SQL node(API Node)mysqldSQL节点(API节点)
192.168.56.102 2202Data Nodendbd数据节点
192.168.56.1031186Mgmt Nodendb_mgmd管理节点
二、准备工作1)关闭防火墙(在三台服务器上操作)
[root@localhost ~]# service iptables stopFlushing firewall rules:                                   [  OK  ]Setting chains to policy ACCEPT: filter                    [  OK  ]Unloading iptables modules:                                [  OK  ][root@localhost local]# chkconfig iptables off
2)默认不启动防火墙(在三台服务器上操作)
 [root@localhost ~]# chkconfig iptables off
3)添加mysql用户和组(在三台服务器上操作)
[root@localhost ~]# groupadd mysql[root@localhost ~]# useradd -g mysql mysql
4)上传安装文件(只需要在192.168.56.101上操作即可)可以使用FileZilla软件来上传安装文件,比如上传到Linux 上的/tmp目录。我使用的安装文件是:mysql-cluster-gpl-7.1.10-linux-i686-glibc23.tar.gz 三、安装Mysql Cluster1.安装数据节点和SQL节点(只需要在192.168.56.101上操作即可)1)安装tar包
[root@localhost ~]# cd /tmp[root@localhost tmp]# tar -C /usr/local -zxvf mysql-cluster-gpl-7.1.10-linux-i686-glibc23.tar.gz[root@localhost tmp]# ln -s /usr/local/mysql-cluster-gpl-7.1.10-linux-i686-glibc23/ /usr/local/mysql[root@localhost tmp]# cd /usr/local/mysql[root@localhost mysql]# scripts/mysql_install_db --usr=mysql
 2)授权
[root@localhost mysql]# cd ..[root@localhost local]# chown -R mysql mysql[root@localhost local]# chgrp -R mysql mysql
 3)创建编辑my.cnf,键入下面内容
 [mysqld]ndbclusterndb-connectstring=192.168.56.103[mysql_cluster]ndb-connectstring=192.168.56.103
 2.将/usr/local/mysql文件夹和/etc/my.cnf拷贝到192.168.56.102上
[root@localhost local]# scp -r ./mysql/* root@192.168.56.102:/usr/local/mysqlThe authenticity of host "192.168.56.102 (192.168.56.102)" can"t be established.RSA key fingerprint is 1f:26:d9:20:d1:77:47:bf:3c:7b:64:6d:68:0f:bb:76.Are you sure you want to continue connecting (yes/no)? yesWarning: Permanently added "192.168.56.102" (RSA) to the list of known hosts.root@192.168.56.102"s password:...........[root@localhost local]# scp -r /etc/my.cnf root@192.168.56.102:/etc/
 3.将/usr/local/mysql文件夹Copy到192.168.56.103(使用scp命令)
[root@localhost local]# scp -r ./mysql/* root@192.168.56.103:/usr/local/mysqlThe authenticity of host "192.168.56.103 (192.168.56.103)" can"t be established.RSA key fingerprint is 1f:26:d9:20:d1:77:47:bf:3c:7b:64:6d:68:0f:bb:76.Are you sure you want to continue connecting (yes/no)? yesWarning: Permanently added "192.168.56.103" (RSA) to the list of known hosts.root@192.168.56.103"s password:
 4.在102 & 103授权
[root@localhost ~]# cd /usr/local[root@localhost local]# chown -R mysql mysql[root@localhost local]# chgrp -R mysql mysql
 5.配置管理节点(在192.168.56.103上操作)
[root@localhost mysql]# mkdir /var/lib/mysql-cluster[root@localhost mysql]# chown -R mysql /var/lib/mysql-cluster[root@localhost mysql]# chgrp -R mysql /var/lib/mysql-cluster[root@localhost mysql]# cd /usr/local/mysql/[root@localhost mysql]# vim config.ini
 键入下面内容到config.ini中
[ndbd default]NoOfReplicas=2 # Number of replicasDataMemory=80M # How much memory to allocate for data storageIndexMemory=18M # How much memory to allocate for index storage[tcp default]portnumber=2202 # This the default; however, you can use any[ndb_mgmd]hostname=192.168.56.103 # Hostname or IP address of MGM nodedatadir=/var/lib/mysql-cluster # Directory for MGM node log files[ndbd]hostname=192.168.56.101 # Hostname or IP addressdatadir=/usr/local/mysql/data # Directory for this data node"s data files[ndbd]hostname=192.168.56.102 # Hostname or IP addressdatadir=/usr/local/mysql/data # Directory for this data node"s data files[mysqld]hostname=192.168.56.101 # Hostname or IP address[mysqld]hostname=192.168.56.102 # Hostname or IP address
 四、启动Mysql Cluster1.启动管理节点后台服务(在192.168.56.103上操作)
[root@localhost mysql]# /usr/local/mysql/bin/ndb_mgmd -f /usr/local/mysql/config.ini
 2.启动管理节点管理服务(在192.168.56.103上操作)
[root@localhost mysql]# /usr/local/mysql/bin/ndb_mgm
 3.查看Mysql Cluster配置信息(在192.168.56.103上操作)
ndb_mgm> showConnected to Management Server at: localhost:1186Cluster Configuration---------------------[ndbd(NDB)]     2 node(s)id=2 (not connected, accepting connect from 192.168.56.101)id=3 (not connected, accepting connect from 192.168.56.102)[ndb_mgmd(MGM)] 1 node(s)id=1    @192.168.56.103  (mysql-5.1.51 ndb-7.1.10)[mysqld(API)]   2 node(s)id=4 (not connected, accepting connect from 192.168.56.101)id=5 (not connected, accepting connect from 192.168.56.102)
 4.启动数据节点(101 & 102上操作)
[root@localhost local]# /usr/local/mysql/bin/ndbd --initial
 5.启动SQL节点(101 & 102上操作)
[root@localhost local]# /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &
 6.再次查看Mysql Cluster配置信息(在192.168.56.103上操作)
ndb_mgm> showCluster Configuration---------------------[ndbd(NDB)]     2 node(s)id=2    @192.168.56.101  (mysql-5.1.51 ndb-7.1.10, Nodegroup: 0, Master)id=3    @192.168.56.102  (mysql-5.1.51 ndb-7.1.10, Nodegroup: 0)[ndb_mgmd(MGM)] 1 node(s)id=1    @192.168.56.103  (mysql-5.1.51 ndb-7.1.10)[mysqld(API)]   2 node(s)id=4    @192.168.56.101  (mysql-5.1.51 ndb-7.1.10)id=5    @192.168.56.102  (mysql-5.1.51 ndb-7.1.10)
 五、Mysql Cluster测试1.在101(102)上创建数据库、表并插入数据
[root@localhost ~]# mysql…mysql> show databases;+--------------------+| Database           |+--------------------+| information_schema || mysql              || ndb_2_fs           || ndbinfo            || test               |+--------------------+5 rows in set (0.00 sec)mysql> create database test1;Query OK, 1 row affected (0.06 sec)mysql> show databases;+--------------------+| Database           |+--------------------+| information_schema || mysql              || ndb_2_fs           || ndbinfo            || test               || test1              |+--------------------+6 rows in set (0.00 sec)mysql> use test1;Database changedmysql> create table tb_test(id int) engine=ndb;Query OK, 0 rows affected (0.36 sec)mysql> insert into tb_test select 1;Query OK, 1 row affected (0.06 sec)Records: 1  Duplicates: 0  Warnings: 0mysql> select * from tb_test;+------+| id   |+------+|    1 |+------+1 row in set (0.00 sec)
2.在102(101)上查看已有的数据库、表和表数据
[root@localhost ~]# mysql…mysql> show databases;+--------------------+| Database           |+--------------------+| information_schema || mysql              || ndb_3_fs           || ndbinfo            || test               || test1              |+--------------------+6 rows in set (0.01 sec)mysql> use test1;Reading table information for completion of table and column namesYou can turn off this feature to get a quicker startup with -ADatabase changedmysql> select * from tb_test;+------+| id   |+------+|    1 |+------+1 row in set (0.00 sec)
通过测试,至此Mysql Cluster配置成功。更多关于MySQL Cluster的详细信息,或者下载地址请点这里Oracle中查询表字段基本信息、主键、外键Oracle学习笔记:用户管理相关资讯      redhat  MySQL教程
