mysql NDB的安装配置使用示例
2024-05-10 08:00:27
1.到mysql网站下载mysql cluster版本 http://www.mysql.com/downloads/cluster/
下载到/home/weijianzhongwj/software下
2.安装mysql cluster
cd /home/weijianzhongwj/software
tar xvf mysql-cluster-gpl-7.2.8-linux2.6-i686.tar.gz
ln -s mysql-cluster-gpl-7.2.8-linux2.6-i686 mysqlc
在$HOME/.bashrc增加 export PATH=$PATH:/home/weijianzhongwj/software/mysqlc/bin 一行，添加mysql的bin目录到path路径中
3.对于一个mysql集群，我们需要启动一个mysql server(mysqld),两个data nodes（NDB），还有一个管理结点（ndb_mgmd),我们测试是在单机中，对于在多台机器上，在data nodes配置的hostname修改为对应机器的ip则可。
我们先来添加爱mysql集群需要的配置文件
先进入mysqlc的目录，在这个目录下创建配置文件目录和数据文件目录
cd /home/weijianzhongwj/software/mysqlc
mkdir my_cluster my_cluster/ndb_data my_cluster/mysqld_data my_cluster/conf然后在my_cluster/conf中创建下面两个文件：
my.cnf
[mysqld]
ndbcluster
datadir=/home/weijianzhongwj/software/mysqlc/my_cluster/mysqld_data
basedir=/home/weijianzhongwj/software/mysqlc
port=5000config.ini
[ndb_mgmd]
hostname=localhost
datadir=/home/weijianzhongwj/software/mysqlc/my_cluster/ndb_data
NodeId=1
[ndbd default]
noofreplicas=2
datadir=/home/weijianzhongwj/software/mysqlc/my_cluster/ndb_data
[ndbd]
hostname=localhost
NodeId=3
[ndbd]
hostname=localhost
NodeId=4
[mysqld]
NodeId=50
然后在mysqlc的目录下，创建名称为mysql数据库，这是所有mysql需要创建的数据库
cd /home/weijianzhongwj/software/mysqlc/
scripts/mysql_install_db --no-defaults --datadir=/home/weijianzhongwj/software/mysqlc//my_cluster/mysqld_data/4.启动管理结点，数据结点，mysql server
weijianzhongwj@ubuntu:~/software/mysqlc$ bin/ndb_mgmd -f my_cluster/conf/config.ini --initial --configdir=/home/weijianzhongwj/software/mysqlc/my_cluster/conf/
