本篇文章给大家分享的是有关 ubuntu9.0 中怎么配置 MySQL 集群,丸趣 TV 小编觉得挺实用的,因此分享给大家学习,希望大家阅读完这篇文章后可以有所收获,话不多说,跟着丸趣 TV 小编一起来看看吧。
测试环境:
Server1: ndbd 192.168.245.11
Server2: ndbd 192.168.245.12
Server3: mysqld ndash;ndb-cluster 192.168.245.13
ndbd:节点。
d ndash;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
mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; ndash;my.cnf 开始 mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; mdash; ndash;
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 ndash;help to get a list of available options and with
# ndash;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 hellip;
# 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 = span >
