  • MySQL Cluster 7.3.5 集群配置实例(入门篇)

    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:192.168.137.101

    NDBD1:192.168.137.102

    NDBD2:192.168.137.103

    SQL1:192.168.137.104

    SQL2:192.168.137.105

    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 --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

    4.4 关闭防火墙(IPTABLES)与 selinux

    # 关闭防火墙

    chkconfig iptables off

    # 关闭 selinux

    vim /etc/selinux/config  #(改为SELINUX=disabled)保存退出,

    # 重启服务器

    init 6

    五、配置节点

    5.1 配置管理节点(192.168.137.101)

    # 删除自带的 /etc/my.cnf  【切记:一定要删除掉! 因为ndb_mgmd启动的时候,也会加上/etc/my.cnf的配置内容,干扰我们,所以要删除它】

    rm -rf /etc/my.cnf

    # 新建配置文件存放目录

    mkdir /usr/local/mysql/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 = 80M
    IndexMemory = 18M
    datadir = /usr/local/mysql/data

    [ndb_mgmd]
    NodeId = 1
    HostName = 192.168.137.101

    [ndbd]
    NodeId = 11  
    HostName = 192.168.137.102

    [ndbd]
    NodeId = 12
    HostName = 192.168.137.103

    [mysqld]
    NodeId = 81
    HostName = 192.168.137.104

    [mysqld] 
    NodeId = 82
    HostName = 192.168.137.105

    5.2 配置数据节点(192.168.137.102、192.168.137.103)

    # 修改配置文件

    vim /etc/my.cnf

    # my.cnf内容如下:

    [mysqld]
    ndbcluster
    ndb-connectstring = 192.168.137.101

    [mysql_cluster]
    ndb-connectstring = 192.168.137.101

    5.3 配置SQL节点(192.168.137.104、192.168.137.105)

    # 拷贝文件

    cp -rf /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

    # 修改配置文件

    vim /etc/my.cnf

    # my.cnf内容如下:

    [mysqld]
    basedir = /usr/local/mysql
    datadir = /usr/local/mysql/data

    ndbcluster
    ndb-connectstring = 192.168.137.101

    [mysql_cluster]
    ndb-connectstring = 192.168.137.101

    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(192.168.137.101)

    # --initial 首次加载、/usr/local/mysql/etc/config.ini文件有改变,其它时候不要加,除非是在备份、恢复或配置变化后重启时,其他时候不要加,不然数据就清空。。。

    /usr/local/mysql/bin/ndb_mgmd  -f  /usr/local/mysql/etc/config.ini --initial

    # 正常启动方式

    /usr/local/mysql/bin/ndb_mgmd  -f  /usr/local/mysql/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 192.168.137.102)
    id=12 (not connected, accepting connect from 192.168.137.103)
    
    [ndb_mgmd(MGM)]    1 node(s)
    id=1    @192.168.137.101  (mysql-5.6.17 ndb-7.3.5)
    
    [mysqld(API)]    3 node(s)
    id=81 (not connected, accepting connect from 192.168.137.104)
    id=82 (not connected, accepting connect from 192.168.137.105)
    id=83 (not connected, accepting connect from any host)

    6.2 启动数据节点(192.168.137.102、192.168.137.103)

    # 只是在第一次启动或在备份/恢复或配置变化后重启ndbd时,才加–initial参数!

    /usr/local/mysql/bin/ndbd --initial

    # 正常启动方式

    /usr/local/mysql/bin/ndbd

    # 查看 ndbd 启动状态

    [root@localhost ~]# ps -ef | grep ndbd
    root      2373     1  0 18:11 ?        00:00:00 /usr/local/mysql/bin/ndbd
    root      2377  1985  0 18:11 pts/0    00:00:00 grep ndbd

    6.3 启动SQL节点(192.168.137.104、192.168.137.105)

    # 启动 SQL 节点

    service mysqld start

    # 关闭 SQL 节点

    service mysqld stop

    # 重启 SQL 节点

    service mysqld restart

    # 检验mysql是否运行

    service mysqld status

    # 为sql指定密码

    /usr/local/mysql/bin/mysqladmin -u root password 'new-password'
    
    /usr/local/mysql/bin/mysqladmin -u root -h 'host' password 'new-password'

    # 启动命令行窗口

    /usr/local/mysql/bin/mysql -u root –p
