1.实验环境

我用三台服务器搭建mysql cluster环境,sql节点和数据节点在同一服务器上,管理节点单独一台.

cluster node1:192.168.1.102 data node1:192.168.1.102

cluster node2:192.168.1.104 data node2:192.168.1.104

manager node:192.168.1.19

OS:CentOS 6.4 64位

2.在sql节点和数据节点安装mysql cluster(注:cluster节点1和节点2是一样的)

cluster node1:

[root@node1 home]# wget

[root@node1 home]# tar xvf mysql-cluster-gpl-7.3.6-linux-glibc2.5-x86_64.tar.gz

[root@node1 home]# mv mysql-cluster-gpl-7.3.6-linux-glibc2.5-x86_64 /usr/local/mysql-cluster-gpl-7.3.6/

[root@node1 home]# cd /usr/local/

[root@node1 local]# groupadd mysql

[root@node1 local]# useradd -r -M -s /sbin/nologin mysql

[root@node1 local]# chown -R root:mysql mysql-cluster-gpl-7.3.6/

[root@node1 local]# chown -R mysql:mysql mysql-cluster-gpl-7.3.6/data/

[root@node1 scripts]# ./mysql_install_db --user=mysql --datadir=/usr/local/mysql-cluster-gpl-7.3.6/data --basedir=/usr/local/mysql-cluster-gpl-7.3.6

[root@node1 scripts]# cd ../bin/

[root@node1 bin]# cp -a ../support-files/mysql.server /etc/init.d/mysqld

[root@node1 bin]# chkconfig --add mysqld

[root@node1 bin]# chkconfig mysqld on

[root@node1 bin]# cp -a ../my.cnf /etc/my.cnf

[root@node1 bin]# vim /etc/my.cnf

[mysqld]

basedir = /usr/local/mysql-cluster-gpl-7.3.6 --数据库的安装路径

datadir = /usr/local/mysql-cluster-gpl-7.3.6/data --数据库的数据目录

port = 3306

ndbcluster --集群服务

ndb-connectstring=192.168.1.19 --管理节点的IP地址

[mysql_cluster]

ndb-connectstring=192.168.1.19 --管理节点的IP地址

[root@node1 bin]# ./mysqld_safe --user=mysql

[root@node1 bin]# /etc/init.d/mysqld restart

ERROR! MySQL server PID file could not be found!

Starting MySQL...................................... SUCCESS!

[root@node1 bin]# netstat -anp |grep mysql

[root@node1 bin]#

cluster node2:

注:节点2上的mysql cluster安装和节点1是一样的,配置文件也是一样

3.管理节点

[root@db2 home]# wget

[root@db2 home]# tar xvf mysql-cluster-gpl-7.3.6-linux-glibc2.5-x86_64.tar.gz

[root@db2 home]# mv mysql-cluster-gpl-7.3.6-linux-glibc2.5-x86_64 /usr/local/mysql-cluster-gpl-7.3.6/

[root@db2 home]# cd /usr/local/

[root@db2 local]# groupadd mysql

[root@db2 local]# useradd -r -M -s /sbin/nologin mysql

[root@db2 local]# chown -R root:mysql mysql-cluster-gpl-7.3.6/

[root@db2 local]# chown -R mysql:mysql mysql-cluster-gpl-7.3.6/data/

[root@db2 scripts]# ./mysql_install_db --user=mysql --datadir=/usr/local/mysql-cluster-gpl-7.3.6/data --basedir=/usr/local/mysql-cluster-gpl-7.3.6

[root@db2 scripts]# cd ../bin/

[root@db2 bin]# cp -a ../my.cnf /etc/my.cnf

[root@db2 bin]# vim /etc/my.cnf

[mysqld]

basedir = /usr/local/mysql-cluster-gpl-7.3.6

datadir = /usr/local/mysql-cluster-gpl-7.3.6/data

port = 3306

[root@db2 home]# /etc/init.d/iptables stop

iptables: Flushing firewall rules: [ OK ]

iptables: Setting chains to policy ACCEPT: filter [ OK ]

iptables: Unloading modules: [ OK ]

[root@db2 home]# mkdir /var/lib/mysql-cluster/

[root@db2 home]# vim /var/lib/mysql-cluster/config.ini --配置文件中注意大小写
