  家在网上都能找到都是RedHat系统等等,对Ubuntu系统MySQL集群就没有介绍文章,我现在写写Ubuntu这个MySQL集群方法。新手不要骂我,呵呵。   介绍网络环境:   测试环境:   Server1: ndbd 192.168.245.11   Server2: ndb

  家在网上都能找到都是RedHat系统等等,对Ubuntu系统MySQL集群就没有介绍文章,我现在写写Ubuntu这个MySQL集群方法。新手不要骂我,呵呵。

  介绍网络环境:

  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

  1. vim /etc/mysql/my.cnf
  2. —————————————–my.cnf开始——————————————–
  3. Ubuntu@ubuntu:~$ cat /etc/mysql/my.cnf
  4. #
  5. # The MySQL database server configuration file.
  6. #
  7. # You can copy this to one of:
  8. # - “/etc/mysql/my.cnf” to set global options,
  9. # - “~/.my.cnf” to set user-specific options.
  10. #
  11. # One can use all long options that the program supports.
  12. # Run program with –help to get a list of available options and with
  13. # –print-defaults to see which it would actually understand and use.
  14. #
  15. # For explanations see # http://dev.mysql.com/doc/mysql/en/serve ... ables.html
  16. # This will be passed to all mysql clients
  17. # It has been reported that passwords should be enclosed with ticks/quotes
  18. # escpecially if they contain “#” chars…
  19. # Remember to edit /etc/mysql/debian.cnf when changing the socket location. [client] port = 3306 socket = /var/run/mysqld/mysqld.sock
  20. # Here is entries for some specific programs
  21. # The following values assume you have at least 32M ram
  22. # This was formally known as [safe_mysqld]. Both versions are currently parsed. [mysqld_safe] socket = /var/run/mysqld/mysqld.sock nice = 0 [mysqld]
  23. #
  24. # * Basic Settings
  25. #
  26. #
  27. # * IMPORTANT
  28. # If you make changes to these settings and your system uses apparmor, you may
  29. # also need to also adjust /etc/apparmor.d/usr.sbin.mysqld.
  30. # 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
  31. #
  32. # Instead of skip-networking the default is now to listen only on
  33. # localhost which is more compatible and is not less secure.
  34. # bind-address = 127.0.0.1
  35. #
  36. # * Fine Tuning
  37. # key_buffer = 16M max_allowed_packet = 16M thread_stack = 128K thread_cache_size = 8
  38. #max_connections = 100 #table_cache = 64 #thread_concurrency = 10
  39. #
  40. # * Query Cache Configuration
  41. # query_cache_limit = 1M query_cache_size =
