家在網上都能找到都是RedHat系統等等，對Ubuntu系統MySQL集群就沒有介紹文章，我現在寫寫Ubuntu這個MySQL集群方法。新手不要罵我，呵呵。
介紹網絡環境：
測試環境：
Server1: ndbd 192.168.245.11
Server2: ndbd 192.168.245.12
Server3: mysqld –ndb-cluster 192.168.245.13
ndbd： 數據庫節點。
mysqld –ndb-cluster： MySQL服務器節點，程序直接訪問的是這台機器的IP。默認端口仍是3306。
ndbd_mgm ndbd_mgmd：管理節點。管理/查看各庫節點和服務器節點的狀態。
二、集群方案
1.管理節點:server3(192.168.245.13)
2.存儲節點:server1(192.168.245.11),server2(192.168.245.12)
3.SQL節點:server1(192.168.245.11),server2(192.168.245.12),server3(192.168.245.13)
三、mysql安裝和配置
1.安裝，sudo apt-get install mysql-server
2.配置這三台服務器上配置my.cnf，這三台服務器都要配置
- vim /etc/mysql/my.cnf
- —————————————–my.cnf開始——————————————–
- 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.sock nice = 0 [mysqld]
- #
- # * Basic Settings
- #
- #
- # * IMPORTANT
- # If you make changes to these settings and your system uses apparmor, you may
- # also need to also adjust /etc/apparmor.d/usr.sbin.mysqld.
- # user = mysql pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp language = /usr/share/mysql/english skip-external-locking
- #
- # Instead of skip-networking the default is now to listen only on
- # localhost which is more compatible and is not less secure.
- # bind-address = 127.0.0.1
- #
- # * Fine Tuning
- # key_buffer = 16M max_allowed_packet = 16M thread_stack = 128K thread_cache_size = 8
- #max_connections = 100 #table_cache = 64 #thread_concurrency = 10
- #
- # * Query Cache Configuration
- # query_cache_limit = 1M query_cache_size =
