在ubuntu9.0上配置MySQL集群详细教程_MySQL

　　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

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.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/
