java程序如何連接Mysql集群？

mysql集群是master-slaver模式，java程序當然是鏈接master那臺機器了，slaver只是給master做輔助的。

mysql cluster 7.1.3 安裝筆記

今天初步安裝了一下mysql cluster,基本上都是按照官方文檔做的,歡迎大家拍磚。

1,服務器使用情況

Management (MGMD) node 192.168.0.10

MySQL server (SQL) node 192.168.0.20

Data (NDBD) node "A" 192.168.0.30

Data (NDBD) node "B" 192.168.0.40

2,安裝Management、Sql node、 Data node 重復以下步驟:

[root@www local]# tar -zxvf mysql-cluster-gpl-7.1.3-linux-i686-glibc23.tar.gz

[root@www local]# mv mysql-cluster-gpl-7.1.3-linux-i686-glibc23 mysql

[root@www local]# groupadd mysql

[root@www local]# useradd -g mysql mysql

[root@www local]# chown -R mysql.mysql mysql

[root@www local]# /usr/local/mysql/scripts/mysql_install_db --user=mysql

[root@www mysql]# cp support-files/mysql.server /etc/rc.d/init.d/

[root@www mysql]# chmod +x /etc/rc.d/init.d/mysql.server

[root@www mysql]# chkconfig --add mysql.server

3,配置Management節(jié)點:

[root@www mysql]# mkdir /var/lib/mysql-cluster

[root@www mysql]# vi /var/lib/mysql-cluster/config.ini

[ndbd default]

NoOfReplicas=2 # Number of replicas

DataMemory=80M # How much memory to allocate for data storage

IndexMemory=18M # How much memory to allocate for 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.

# TCP/IP options:

[tcp default]

portnumber=2202 # This the default; however, you can use any port that is free

# for all the hosts in the cluster

# Note: It is recommended that you do not specify the port

# number at all and allow the default value to be used instead

# Management process options:

[ndb_mgmd]

hostname=192.168.0.10 # Hostname or IP address of management node

datadir=/var/lib/mysql-cluster # Directory for management node log files

# Options for data node "A":

[ndbd]

# (one [ndbd] section per data node)

hostname=192.168.0.30 # Hostname or IP address

datadir=/usr/local/mysql/data # Directory for this data node's data files

# Options for data node "B":

[ndbd]

hostname=192.168.0.40 # Hostname or IP address

datadir=/usr/local/mysql/data # Directory for this data node's data files

# SQL node options:

[mysqld]

hostname=192.168.0.20 # Hostname or IP address

# (additional mysqld connections can be

# specified for this node for various

# purposes such as running ndb_restore)

[root@www mysql-cluster]# cp bin/ndb_mgm* /usr/local/bin

4,配置MySQL server (SQL) node:

創(chuàng)建 /etc/my.cnf并添加下面的內(nèi)容

#ptions for mysqld process:

[mysqld]

ndbcluster # run NDB storage engine
