家在网上都能找到都是RedHat系统等等,对Ubuntu系统MySQL集群就没有引见文章,我如今写写Ubuntu这个MySQL集群方法。老手不要骂我,呵呵。
引见网络环境:
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: 数据库节点。
mysqld –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形状。
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. [client] port = 3306 socket = /var/run/mysqld/mysqld.sock
- # Here is entries for some specific programs
- # The following values assume you have at least 32M ram
- # This was formally known as [safe_mysqld]. Both versions are currently parsed. [mysqld_safe] socket = /var/run/mysqld/mysqld.s
