本篇文章给大家分享的是有关ubuntu9.0中怎么配置MySQL集群,小编觉得挺实用的,因此分享给大家学习,希望大家阅读完这篇文章后可以有所收获,话不多说,跟着小编一起来看看吧。
测试环境:
Server1: ndbd 192.168.245.11
Server2: ndbd 192.168.245.12
Server3: mysqld –ndb-cluster 192.168.245.13
ndbd: 节点。
d –ndb-cluster: MySQL服务器节点,程序直接访问的是这台机器的IP。默认端口仍是3306。
ndbd_mgm ndbd_mgmd:管理节点。管理/查看各库节点和服务器节点的状态。
二、集群方案
1.管理节点:server3(192.168.245.13)
2.存储节点:server1(192.168.245.11),server2(192.168.245.12)
3.SQL节点:server1(192.168.245.11),server2(192.168.245.12),server3(192.168.245.13)
三、mysql安装和配置
1.安装,sudo apt-get install mysql-server
2.配置这三台服务器上配置my.cnf,这三台服务器都要配置
vim /etc/mysql/my.cnf —————————————–my.cnf开始——————————————– Ubuntu@ubuntu:~$ cat /etc/mysql/my.cnf # # The MySQL database server configuration file. # # You can copy this to one of: # - “/etc/mysql/my.cnf” to set global options, # - “~/.my.cnf” to set user-specific options. # # One can use all long options that the program supports. # Run program with –help to get a list of available options and with # –print-defaults to see which it would actually understand and use. # # For explanations see # http://dev.mysql.com/doc/mysql/en/serve ... ables.html # This will be passed to all mysql clients # It has been reported that passwords should be enclosed with ticks/quotes # escpecially if they contain “#” chars… # Remember to edit /etc/mysql/debian.cnf when changing the socket location.
