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,我目前写写Ubuntu这个MySQL集群办法.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,程序直接拜候的是这台机械的IP.默许端口还是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况.
2、集群筹划
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)
3、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/
- Ubuntu@ubuntu:~$
