HomeDatabaseMysql TutorialUbuntu系统:存储节点(NDB)的安装及配置

本节我们学习在Ubuntu系统下安装、配置mysql-data1.mytest.com和mysql-data2.mytest.com。

安装MySQL

在mysql-data1和mysql-data2两台服务器上,分别安装MySQL服务器:

$ sudo apt-get update install mysql-server

安装时,安装程序会要求你设置MySQL的root口令。请设置好,,并记住该口令。

程序安装完成后,请先停止MySQL服务:

$ sudo /etc/init.d/mysql stop

 配置my.cnf

在mysql-data1和mysql-data2两台服务器上,要执行相同的操作。

首先,备份原有的/etc/mysql/my.cnf:

$ sudo mv /etc/mysql/my.cnf /etc/mysql/my.cnf-back

然后,编辑一个新的my.cnf:

$ sudo nano /etc/mysql/my.cnf

内容如下:

[client]

socket = /var/run/mysqld/mysqld.sock

port    = 3306

[mysqld]

ndbcluster

ndb-connectstring=192.168.1.10   # 管理节点的 IP 地址

default-storage-engine=NDBCLUSTER

[mysql_cluster]

ndb-connectstring=192.168.1.10   # 管理节点的 IP 地址

文件保存后,就可以启动ndb服务了:

$ sudo /etc/init.d/mysql-ndb start-initial

提示  平时启动ndb服务时,用/etc/init.d/mysql-ndb start即可。在下列情况下,要使用/etc/init.d/mysql-ndb start-initial("初始化"启动):

第一次启动ndb服务;

管理节点更改配置后。

如果你在启动ndb服务时遇到下列错误:

 * Starting MySQL NDB Data Node ndbd                                         error=2350

2009-02-15 22:20:55 [ndbd] INFO     -- Error handler restarting system

2009-02-15 22:20:55 [ndbd] INFO     -- Error handler shutdown completed - exiting

sphase=0

exit=-1

则说明ndb服务已经启动了。使用下面的命令可以查看ndb服务是否已经启动:

$ ps aux|grep ndb|grep -v grep

现在,可以启动mysql服务了:

$ sudo /etc/init.d/mysql start

linux
