Windows下搭建Mysql集群

Mysql集群的基本架構如下：

基本原理參考：【轉】MySQL Cluster （集群）基本原理

這里采用最小配置，用兩台機器來分別部署一個management 節點，2個data node, 2個sql node.

Management Node:    192.168.0.102

Data Node A:            192.168.0.102

Data Node B:            192.168.0.104

Sql Node A:               192.168.0.102

Sql Node B:               192.168.0.104

1. 首先從Mysql官方網站上下載最新的Mysql Cluster免安裝包 （http://downloads.mysql.com/archives/cluster/）

注意我們下載的是ZIP Archive

2.將免安裝包分別解壓到兩台機器的C:\Mysql文件夾下

3. 在Management Node的C:\Mysql\Bin下新建Config文件夾，用來存放cluster的配置文件。

3.1首先需要為management node創建一個默認配置文件my.ini ,內容如下:

[mysql_cluster]
# Options for management node process
config-file=C:/mysql/bin/config/config.ini

3.2 創建整個cluster的配置文件config.ini

[ndbd default]
# Options affecting ndbd processes on all data nodes:
NoOfReplicas=2                      # Number of replicas
DataDir=C:/mysql/bin/cluster-data   # Directory for each data node's data files
                                    # Forward slashes used in directory path,
                                    # rather than backslashes. This is correct;
                                    # see Important note in text
DataMemory=80M    # Memory allocated to data storage
IndexMemory=18M   # Memory allocated to index storage
                  # For DataMemory and IndexMemory, we have used the
                  # default values. Since the "world" database takes up
                  # only about 500KB, this should be more than enough for
                  # this example Cluster setup.

[ndb_mgmd]
# Management process options:
HostName=192.168.0.102              # Hostname or IP address of management node
DataDir=C:/mysql/bin/cluster-logs   # Directory for management node log files

[ndbd]
# Options for data node "A":
                             # (one [ndbd] section per data node)
HostName=192.168.0.102           # Hostname or IP address

[ndbd]
# Options for data node "B":

HostName=192.168.0.104           # Hostname or IP address

[mysqld]
# SQL node A options:

HostName=192.168.0.102           # Hostname or IP address

[mysqld]
# SQL node B options:

HostName=192.168.0.104           # Hostname or IP address

4. 啟動Management Node,命令如下:

c:\mysql\bin\ndb_mgmd.exe --configdir=c:\mysql\bin\config --config-file=c:\mysql\bin\config\config.ini --ndb-nodeid=1 --reload –initial

5.啟動Data Node A,命令如下:

c:\mysql\bin\ndbd.exe --ndb-connectstring=192.168.0.102

6.啟動Data Node B,命令如下:

c:\mysql\bin\ndbd.exe --ndb-connectstring=192.168.0.102

7.可以打開management client來查看cluster當前的狀態

 

8.Data Node均啟動后，接下來分別啟動兩個Sql Node，命令如下:

c:\mysql\bin\mysqld.exe --ndbcluster --ndb-connectstring=192.168.0.102 --console
9. 通過management client查看cluster的當前狀態

10.至此，cluster已經成功啟動。

11.在Sql Node A上創建數據庫ClusterSample

注：默認root密碼為空

12.在Sql Node A上創建數據表Person;

13. 通過Sql Node A插入數據；

14.在Sql Node B上去查詢數據
