虛擬機器Ubuntu 9.04下MySQL叢集的配置方法

大家在網上都能找到都是RedHat系統等等，對Ubuntu系統MySQL叢集就沒有介紹文章

我現在寫寫Ubuntu這個MySQL叢集方法。新手不要罵我，呵呵。

介紹網路環境：

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： 資料庫節點。
mysqld –ndb-cluster： MySQL伺服器節點，程式直接存取的是這台機器的IP。預設連接埠仍是3306。
ndbd_mgm ndbd_mgmd：管理節點。管理／查看各庫節點和伺服器節點的狀態。

二、叢集方案
1.管理節點:server3(192.168.245.13)
2.儲存節點: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.配置這三台伺服器上配置my.cnf，這三台伺服器都要配置
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 = 16M
#
# * Logging and Replication
#
# Both location gets rotated by the cronjob.
# Be aware that this log type is a performance killer.
#log = /var/log/mysql/mysql.log
#
# Error logging goes to syslog. This is a Debian improvement
#
# Here you can see queries with especially long duration
#log_slow_queries = /var/log/mysql/mysql-slow.log
#long_query_time = 2
#log-queries-not-using-indexes
#
# The following can be used as easy to replay backup logs or for replication.
# note: if you are setting up a replication slave, see README.Debian about
# other settings you may need to change.
#server-id = 1
#log_bin = /var/log/mysql/mysql-bin.log
expire_logs_days = 10
max_binlog_size = 100M
#binlog_do_db = include_database_name
#binlog_ignore_db = include_database_name
#
# * BerkeleyDB
#
# Using BerkeleyDB is now discouraged as its support will cease in 5.1.12.
skip-bdb
#
# * MyISAM
#
# MyISAM is enabled by default with a 10MB datafile in /var/lib/mysql/.
# Read the manual for more MyISAM related options. There are many!
# You might want to disable MyISAM to shrink the mysqld process by circa 100MB.
#skip-innodb
#
# * Security Features
#
# Read the manual, too, if you want chroot!
# chroot = /var/lib/mysql/
#
# For generating SSL certificates I recommend the OpenSSL GUI “tinyca”.
#
# ssl-ca=/etc/mysql/cacert.pem
# ssl-cert=/etc/mysql/server-cert.pem
# ssl-key=/etc/mysql/server-key.pem

ndbcluster
ndb-connectstring=192.168.245.13

[mysqldump]
quick
quote-names
max_allowed_packet = 16M

[mysql]
#no-auto-rehash # faster start of mysql but no tab completition

[isamchk]
key_buffer = 16M

#
# * NDB Cluster
#
# See /usr/share/doc/mysql-server-*/README.Debian for more information.
#
# The following configuration is read by the NDB Data Nodes (ndbd processes)
# not from the NDB Management Nodes (ndb_mgmd processes).
#
[MYSQL_CLUSTER]

ndb-connectstring=192.168.245.13

#
# * IMPORTANT: Additional settings that can override those from this file!
# The files must end with ‘.cnf’, otherwise they’ll be ignored.
#
!includedir /etc/mysql/conf.d/

ubuntu@ubuntu:~$
———————————my.cnf結束———————————————————

主要在：[mysqld]下添加：

ndbcluster
ndb-connectstring=192.168.245.13
和添加
[MYSQL_CLUSTER]

ndb-connectstring=192.168.245.13

上面三台伺服器都要一樣
