一、安装要求
安装环境:CentOS-6.5-32bit
软件名称:mysql-cluster-gpl-7.2.25-linux2.6-i686.tar.gz
下载地址:http://mysql.mirror.kangaroot.net/Downloads/
软件包:mysql-cluster-gpl-7.2.25-linux2.6-i686.tar.gz
软件包存放目录:/usr/local
管理节点(MGM): 192.168.1.71
数据节点1(NDBD1):192.168.1.72
数据节点2(NDBD2):192.168.1.73
sql节点1(SQL1): 192.168.1.74
sql节点2(SQL2): 192.168.1.75
二、安装部署
1.安装前:(所有节点服务器需执行)
[[email protected] ]#rpm -qa|grep mysql* (查询系统中存在的mysql)
[[email protected] ]#rpm -e –nodeps mysql-libs-5.1.71-1.el6.i686 (根据自己查出来的mysql版本)
2.开始部署:(所有节点服务器需执行)
[[email protected] ]#groupadd mysql
[[email protected] ]#useradd mysql -g mysql
[[email protected] ]#cd /usr/local (软件包在此目录下,根据自己存放位置进入)
[[email protected] local]#tar -xvf mysql-cluster-gpl-7.2.25-linux2.6-i686.tar.gz
[[email protected] local]#mkdir /usr/local/mysql (创建mysql目录)
[[email protected] local]#mv mysql-cluster-gpl-7.2.25-linux2.6-i686/* mysql
[[email protected] local]#chown -R mysql:mysql mysql/
[[email protected] local]#cd mysql
[[email protected] mysql]#scripts/mysql_install_db –user=mysql (管理及数据节点执行这条命令)
#scripts/mysql_install_db –user=mysql –datadir=/var/mysql/data (sql节点执行这条命令)
或者
scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql --ldata=/var/mysql/data/

三、集群配置
1.管理节点配置:
[[email protected] mysql]#mkdir /var/lib/mysql-cluster
[[email protected] ]#mkdir /var/mysql
[[email protected] ]#mkdir /var/mysql/data
[[email protected] ]#mkdir /var/mysql/log
[[email protected] mysql]#vi /var/lib/mysql-cluster/config.ini (添加以下内容)
[NDBD DEFAULT]
NoOfReplicas=2
#[TCP DEFAULT]
#PortNumber=1186
[NDB_MGMD]
#设置管理节点服务器
nodeid=1
HostName=192.168.1.71
DataDir=/var/mysql/data
[NDBD]
nodeid=2
HostName=192.168.1.72
DataDir=/var/mysql/data
[NDBD]
nodeid=3
HostName=192.168.1.73
DataDir=/var/mysql/data
[MYSQLD]
nodeid=4
HostName=192.168.1.74
[MYSQLD]
nodeid=5
HostName=192.168.1.75
#必须有空的mysqld节点,不然数据节点断开后启动有报错
[MYSQLD]
nodeid=6
[mysqld]
nodeid=7
拷贝ndb_mgm、ndb_mgmd、config.ini到bin目录:
[[email protected] mysql]#cd /usr/local/mysql/bin
[[email protected] bin]#cp ./ndb_mgm /usr/local/bin/
[[email protected] bin]#cp ./ndb_mgmd /usr/local/bin/
[[email protected] bin]#cp /var/lib/mysql-cluster/config.ini /usr/local/bin/
[[email protected] bin]#vi /etc/sysconfig/iptables 添加如下内容
-A INPUT -m state --state NEW -m tcp -p tcp --dport 1186 -j ACCEPT
[[email protected] bin]/etc/init.d/iptables restart 重启防火墙
2.数据节点配置:(所有数据节点需执行)
[[email protected] ]#mkdir /var/mysql
[[email protected] ]#mkdir /var/mysql/data
[[email protected] ]#mkdir /var/mysql/log
[[email protected] ]#/etc/init.d/iptables stop (关闭防火墙,也可自行添加开放端口)
[[email protected] ]#vi /etc/my.cnf (添加以下内容)
[mysqld]
datadir=/var/mysql/data
socket=/var/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
#运行NDB存储引擎
ndbcluster
#指定管理节点
ndb-connectstring=192.168.1.71
[MYSQL_CLUSTER]
ndb-connectstring=192.168.1.71
[NDB_MGM]
connect-string=192.168.1.71
[mysqld_safe]
log-error=/var/mysql/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
3.sql节点配置:(所有sql节点需执行)
[[email protected] ]#cd /usr/local/mysql/
[[email protected] mysql]#cp support-files/mysql.server /etc/rc.d/init.d/mysqld
[[email protected] mysql]#chmod +x /etc/rc.d/init.d/mysqld
[[email protected] mysql]#chkconfig –add mysqld
[[email protected] mysql]#mkdir /var/mysql
[[email protected] mysql]#mkdir /var/mysql/data
[[email protected] mysql]#mkdir /var/mysql/log
[[email protected] mysql]#chown -R mysql:mysql /var/mysql
[[email protected] mysql]#ln -s /usr/local/mysql/bin/mysql /usr/bin
[[email protected] mysql]#ln -s /var/mysql/mysql.sock /tmp/mysql.sock
[[email protected] mysql]#vi /etc/my.cnf
[mysqld]
datadir=/var/mysql/data
socket=/var/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
log-bin = /var/mysql/log/mysql-bin.log
max_connections=1000
#以下为mysql 主主模式的配置文件
# 忽略mysql数据库复制
binlog-ignore-db=mysql
# 每次增长2
auto-increment-increment=2
# 设置自动增长的字段的偏移量,即初始值为2
auto-increment-offset=1
ndbcluster
ndb-connectstring=192.168.1.71
[MYSQL_CLUSTER]
ndb-connectstring=192.168.1.71
[NDB_MGM]
connect-string=192.168.1.71
[mysqld_safe]
log-error=/var/mysql/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
四、mysql-cluster启动
1.启动mysql-cluster
mysql集群的启动顺序为:管理节点->数据节点->SQL节点
mysql集群的关闭顺序为,SQL节点->数据节点->管理节点
2.管理节点:
[[email protected] ]#ndb_mgmd -f /var/lib/mysql-cluster/config.ini –initial(注意第一次或者对config文件进行修改后,打开服务一定要加上initial否则新增加的内容不会被使用)
3.数据节点:
[[email protected] ]#/usr/local/mysql/bin/ndbd – initial(此处同上)
4.sql节点:
[[email protected] ]#service mysqld start
5.验证:(在管理节点上)
[[email protected] mysql]# 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 @192.168.1.72 (mysql-5.5.50 ndb-7.2.25, Nodegroup: 0, *)
id=3 @192.168.1.73 (mysql-5.5.50 ndb-7.2.25, Nodegroup: 0)
[ndb_mgmd(MGM)] 1 node(s)
id=1 @192.168.1.71 (mysql-5.5.50 ndb-7.2.25)
[mysqld(API)] 4 node(s)
id=4 @192.168.1.74 (mysql-5.5.50 ndb-7.2.25)
id=5 @192.168.1.75 (mysql-5.5.50 ndb-7.2.25)
id=6 (not connected, accepting connect from any host)
id=7 (not connected, accepting connect from any host)
五、测试
1.在sql1节点执行:
[[email protected] ]#mysql 调用mysql
mysql>create database tianyuan; 创建数据库
mysql>use tianyuan; 使用数据库
mysql>create table test(i int,name varchar(10)) engine=ndbcluster; 创建表
mysql>insert into test values(1,‘ceshi‘); 插入表数据
mysql>select * from test; 查询验证
2.在sql2节点验证sql1的数据是否已同步到sql2:
[[email protected] ]#mysql 调用mysql
mysql>show databases; 查询数据库
mysql>use tianyuan; 使用数据库
mysql>select * from test; 查询验证
3.可通过中断数据节点或sql节点来验证数据是否会同步。
