MySQL群集双机模拟

MySQL群集双机模拟2008-02-18硬件配置

普通PC server * 2 （最小集群环境需要4台服务器）

模拟环境

red hat linux9 for x86 （or red hat AS 2以上版本）,glibc-2.2, static, gcc

MySQL版本4.1.12 binares

mysql-max binary版本目前只支持linux、max os x和solaris

本方案不涉及从源代码编译安装

主机 IP地址用途

ndb1_mgmd_sqld 1192.168.1.100 Ndb node1+mgmd node1+sqld node1

ndb2_sqld2 192.168.1.200 Ndb node2+sqld node2

Mgmd:management server

sqld:mysql server

ndb:storaged node （share-nothing,base in memory）

安装

从http://dev.mysql.com/downloads/mysql/4.1.html下载mysql-max-4.1.12-pc-linux-gnu-i686.tar.gz到/var/tmp

Storage and SQL Node Installation

在两台主机上执行如下过程

shell>groupadd mysql

shell>useradd -g mysql mysql

shell>tar zxfv mysql-max-4.1.12-pc-linux-gnu-i686.tar.gz

shell>cp -vr mysql-max-4.1.12-pc-linux-gnu-i686 /usr/local/mysql-max-4.1.12-pc-linux-gnu-i686

shell>cd /usr/local

shell>ln -s mysql-max-4.1.12-pc-linux-gnu-i686 mysql

shell>cd mysql;scripts/mysql_install_db –user=mysql

shell>chown -R root .;chown -R mysql data;chgrp -R mysql .

shell>cp support-files/mysql.server /etc/rc.d/init.d/

shell>chmod +x /etc/rc.d/init.d/mysql.server

shell>chkconfig --add mysql.server

shell>chkconfig –level 3 mysql.server off

Management Node Installation

在主机ndb1_mgmd_sqld1上执行如下过程

shell>cd /var/tmp

shell>tar -zxvf mysql-max-4.1.12a-pc-linux-gnu-i686.tar.gz /usr/local/bin "*/bin/ndb_mgm*"

Configuration

Configuring the Storage and SQL Nodes

在两台主机上执行如下过程：

shell>vi /etc/my.cnf

[MYSQLD] # Options for mysqld process:

ndbcluster # run NDB engine

ndb-connectstring=192.168.1.100 # location of MGM node

[MYSQL_CLUSTER] # Options for ndbd process:

ndb-connectstring=192.168.1.100 # location of MGM node
