一、环境说明: CentOS6.3(32位) + MySQL Cluster 7.3.5,规划5台机器,资料如下:
节点分布情况:
MGM:192.168.10.102
NDBD1:192.168.10.101
NDBD2:192.168.10.99
SQL1:192.168.10.98
SQL2:192.168.10.97
二、下载安装包:
主要有三种类型的安装包:1:rpm安装包;2:预编译二进制安装包; 3:源码包。 这里选择第二种安装包“预编译二进制安装包”,它只需要解压即可。
先官网下载页面http://dev.mysql.com/downloads/cluster/ ,选择 Linux - Generic 下面的 mysql-cluster-gpl-7.3.5-linux-glibc2.5-i686.tar.gz 这个安装包!
注意:我的CentOS是32位的,如果是64位系统则应该下载64位的安装包 mysql-cluster-gpl-7.3.5-linux-glibc2.5-x86_64.tar.gz。
三、环境清理(在各台服务器上都要执行)
清除MySQL旧版本:
首先使用如下命令来清理之前操作系统自带的MySQL安装:
yum -y remove mysql
然后使用如下命令:
[root@localhost src]#
rpm -qa | grep mysql*
mysql-libs-5.1.61-4.el6.i686
apr-util-mysql-1.3.9-3.el6_0.1.i686
对于找到的2个剩余MySQL包,按照如下的命令格式予以删除:
rpm -e --nodeps mysql-libs-5.1.61-4.el6.i686
rpm -e --nodeps apr-util-mysql-1.3.9-3.el6_0.1.i686
四、软件准备(在各台服务器上都要执行)
4.1 将 mysql-cluster-gpl-7.3.5-linux-glibc2.5-i686.tar.gz 上传到各服务器的某个目录下(如/usr/local/src) 下面,然后解压并移到/usr/local/mysql目录下
tar -xzvf /usr/local/src/mysql-cluster-gpl-7.3.5-linux-glibc2.5-i686.tar.gz
mv /usr/local/src/mysql-cluster-gpl-7.3.5-linux-glibc2.5-i686/* /usr/local/mysql
4.2 新建mysql用户及用户组:
groupadd mysql
useradd -g mysql -s /usr/sbin/nologin mysql
chown -R mysql:mysql /usr/local/mysql
4.3安装 My Cluster:
cd /usr/local/mysql
./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data
五、配置节点
5.1 配置管理节点(192.168.10.102)
#新建配置文件存放目录
mkdir /usr/local/etc
chown mysql:mysql /usr/local/mysql/etc
#创建配置文件 config.ini
vim /usr/local/mysql/etc/config.ini
config.ini内容如下:
[ndb_mgmd default]datadir = /usr/local/mysql/data
[ndbd default]
NoOfReplicas = 2
DataMemory = 3G
IndexMemory = 1G
datadir = /usr/local/mysql/data
[ndb_mgmd]
NodeId = 1
hostname = 192.168.10.102
[ndbd]
NodeId = 11
hostname = 192.168.10.101
[ndbd]
NodeId = 12
hostname = 192.168.10.99
[mysqld]
NodeId = 81
hostname = 192.168.10.98
[mysqld]
NodeId = 82
hostname = 192.168.10.97
[mysqld]
5.2 配置数据节点(192.168.10.101、192.168.10.99)
vim /etc/my.cnf
my.cnf内容如下:
[mysqld]
ndbcluster
ndb-connectstring = 192.168.10.102
[mysql_cluster]ndb-connectstring = 192.168.10.102
5.3 配置SQL节点(192.168.10.98、192.168.10.97)
vim /etc/my.cnf
my.cnf内容如下:
[mysqld]
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
ndbclusterndb-connectstring = 192.168.10.102
[mysql_cluster]ndb-connectstring = 192.168.10.102
六、启动节点
启动需要按照如下顺序进行:Management Node > Data Node > SQL Node
6.1启动管理节点(192.168.10.102)
/usr/local/mysql/bin/ndb_mgmd -f /usr/local/etc/config.ini
其他常用操作:
#查看ndb_mgmd是否启动
[root@localhost mysql]#
ps -ef | grep ndb_mgmd
root 2948 1 1 23:47 ? 00:00:03 /usr/local/mysql/bin/ndb_mgmd -f /usr/local/mysql/etc/config.ini
root 2984 2073 0 23:52 pts/0 00:00:00 grep ndb_mgmd
[root@localhost mysql]#
#ndb_mgmd默认启动1186端口
[root@localhost mysql]#
netstat -ntlp | grep ndb_mgmd
tcp 0 0 0.0.0.0:1186 0.0.0.0:* LISTEN 2948/ndb_mgmd
[root@localhost mysql]#
#查看集群状态
[root@localhost mysql]#
/usr/local/mysql/bin/ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> show
Connected to Management Server at: localhost:1186
Cluster Configuration
---------------------
[ndbd(NDB)] 2 node(s)
id=11 (not connected, accepting connect from 192.168.10.101)
id=12 (not connected, accepting connect from 192.168.10.99)
[ndb_mgmd(MGM)] 1 node(s)id=1 @192.168.10.102 (mysql-5.6.17 ndb-7.3.5)
[mysqld(API)] 3 node(s)
id=81 (not connected, accepting connect from 192.168.10.98)
id=82 (not connected, accepting connect from 192.168.10.97)
