前言,
    上篇写的是配置mysql cluster,本编写在线添加存储节点
    
   
 
 第一步,参考上篇文档或相关技术材料,为需要新加的存储节点安装正确的mysql版本.
    本实验中,是用mysql-cluster-gpl-7.1.10-linux-x86_64-glibc23.tar.gz
    新加如下2台机器,做为新的存储节点:192.168.133.104,192.168.133.76,在这两台机器获取正确版本并做如下操作:
   
        #mkdir -p /usr/local/mysql/ndbdata
        #groupadd mysql
        #useradd –g mysql mysql
        #tar zxvf mysql-cluster-gpl-7.1.10-linux-x86_64-glibc23.tar.gz
        #chown mysql:mysql  mysql-cluster-gpl-7.1.10-linux-x86_64-glibc23
        #cd  mysql-cluster-gpl-7.1.10-linux-x86_64-glibc23
        #mv * /usr/local/mysql
       
       
       
第二步、修改config.ini,添加[ndbd],例如
[ndbd]
Id = 3
HostName = 192.168.133.104
[ndbd]
Id = 4
HostName = 192.168.133.76

第三步、停止管理节点
ndb_mgm> 1 STOP

Node 1 has shut down.//节点10就是管理节点
Disconnecting to allow Management Server to shutdown
第四步、启动管理节点
[root@localhost bin]# ndb_mgmd -f /var/lib/mysql-cluster/config.ini --reload --initial
MySQL Cluster Management Server mysql-5.1.51 ndb-7.1.10
2011-05-06 18:49:04 [MgmtSrvr] WARNING  -- at line 7: [TCP] portnumber is deprecated


第四步、按顺序一个个启动存储节点
ndb_mgm> 7 RESTART //重启节点7（存储节点）
Node 7: Node shutdown initiated
Node 7: Node shutdown completed, restarting, no start.
Node 7 is being restarted

ndb_mgm> Node 7: Started (version 7.1.10)

ndb_mgm> 8 RESTART //重启节点8
 8 restart
Node 8: Node shutdown initiated
Node 8: Node shutdown completed, restarting, no start.

Node 8 is being restarted

ndb_mgm>
ndb_mgm> Node 8: Start initiated (version 7.1.10)

ndb_mgm>
ndb_mgm>
ndb_mgm> Node 8: Started (version 7.1.10)


第五步、重启SQL节点（API节点）
shell> service mysqld restart

第六步、启动新存储几点并且初始化
shell> ndbd --initial

在管理节点show查看变化

ndb_mgm> show
