篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Mysql高开用集群搭建相关的知识，希望对你有一定的参考价值。
环境
rhel6.5x64
192.168.20.11 mysql11
192.168.29.12 mysql12
拓扑
环境
关闭iptables
关闭selinux
yum -y install ncurses-devel gcc gcc-c++make autoconf automake zlib zlib-devel openssl openssl-devel pcre-devel
开始安装配置mysql11
[[email protected] ~]# tar -xf MySQL-Cluster-gpl-7.3.7-1.el6.x86_64.rpm-bundle.tar [[email protected] ~]# scpMySQL-Cluster-gpl-7.3.7-1.el6.x86_64.rpm-bundle.tar [email protected]:/root [[email protected] ~]# yum -y remove mysql* [[email protected] ~]# mkdir /var/lib/mysql [[email protected] ~]# mkdir /var/lib/mysql-cluster [[email protected] ~]# mkdir /var/run/mysqld [[email protected] ~]# rpm -ivhMySQL-Cluster-server-gpl-7.3.7-1.el6.x86_64.rpm [[email protected] ~]# id mysql uid=498(mysql) gid=498(mysql)groups=498(mysql) [[email protected] ~]# chown mysql:mysql -R/var/lib/mysql [[email protected] ~]# chown mysql:mysql -R/var/lib/mysql-cluster [[email protected] ~]# chown mysql:mysql -R/var/run/mysqld/
配置mysql12
[[email protected] ~]# yum remove mysql -y [[email protected] ~]# rpm -qa | grep mysql* mysql-libs-5.1.71-1.el6.x86_64 [[email protected] ~]# rpm -e --nodepsmysql-libs-5.1.71-1.el6.x86_64
其实我觉得/var/lib/mysql /var/lib/mysql-cluster/var/run/mysqld这三个路径会自动生成
来试试
[[email protected] ~]# rpm -ivhMySQL-Cluster-server-gpl-7.3.7-1.el6.x86_64.rpm
看看，这里有了
[[email protected] ~]# ls /var/lib/mysql ibdata1 ib_logfile1 ndbinfo RPM_UPGRADE_HISTORY test ib_logfile0 mysql performance_schema RPM_UPGRADE_MARKER-LAST [[email protected] ~]# ls/var/lib/mysql-cluster/ [[email protected] ~]# mkdir/var/lib/mysql-cluster mkdir: cannot create directory`/var/lib/mysql-cluster‘: File exists [[email protected] ~]# id mysql uid=498(mysql) gid=498(mysql)groups=498(mysql) [[email protected] ~]# ls /var/run/mysqld [[email protected] ~]# mkdir /var/run/mysqld mkdir: cannot create directory`/var/run/mysqld‘: File exists [[email protected] ~]# /var/run/mysqld -bash: /var/run/mysqld: is a directory [[email protected] ~]# ll -d /var/run/mysqld drwxr-xr-x 2 root root 4096 Aug 27 23:29/var/run/mysqld [[email protected] ~]# ll -d/var/lib/mysql-cluster drwxr-xr-x 2 root root 4096 Aug 27 23:29/var/lib/mysql-cluster [[email protected] ~]# ll -d /var/lib/mysql drwxr-xr-x 6 mysql mysql 4096 Aug 27 23:53/var/lib/mysql [[email protected] ~]#
改成mysql用户所有吧
[[email protected] ~]# chown mysql:mysql -R/var/lib/mysql [[email protected] ~]# chown mysql:mysql -R/var/lib/mysql-cluster [[email protected] ~]# chown mysql:mysql -R/var/run/mysqld/
配置mysql11成为管理节点
主要是两个命令：ndb_mgmd 和 ndb_mgm
[[email protected] ~]# which ndb_mgm /usr/bin/ndb_mgm [[email protected] ~]# rpm -qf /usr/bin/ndb_mgm MySQL-Cluster-server-gpl-7.3.7-1.el6.x86_64 [[email protected] ~]# which ndb_mgmd /usr/sbin/ndb_mgmd [[email protected] ~]# rpm -qf/usr/sbin/ndb_mgmd MySQL-Cluster-server-gpl-7.3.7-1.el6.x86_64
生成配置文件
[[email protected] ~]# cd /var/lib/mysql-cluster [[email protected] mysql-cluster]# vimconfig.ini
#配置文件的内容：
[ndbd default]
NoOfReplicas=2 #数据写入数量。2 表示两份，这样当其中一个存储节点坏了，另一个还可以正常使用。
DataMemory=200M #配置数据存储可以使用的内存
IndexMemory=100M #配置缓存索引可以使用的内存
[ndb_mgmd]
id=1
datadir=/var/lib/mysql-cluster # 指定存放管理结点的日志
HostName=192.168.20.11 #管理结点的 IP 地址。本机 IP
###### data node options: #存储结点
[ndbd]
HostName=192.168.20.11
DataDir=/var/lib/mysql #mysql 数据存储路径
id=2
[ndbd]
HostName=192.168.20.12
DataDir=/var/lib/mysql
id=3
# SQL node options: #关于 SQL 结点
[mysqld]
HostName=192.168.20.11 # 指定可以连接 ndbd 引擎的 sql 结点。
id=4
[mysqld]
HostName=192.168.20.12 # 指定可以连接 ndbd 引擎的 sql 结点。
id=5
mysql11数据节点+SQL 节点配置文档：
配置的内容要手动写呢！
[[email protected] ~]# vim /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql #mysql数据存储路径[单独的SQL节点不需要这行]
ndbcluster #启动 ndb 引擎
ndb-connectstring=192.168.20.11 # 管理节点 IP 地址
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
[mysql_cluster]
ndb-connectstring=192.168.20.11 # 管理节点 IP 地址
再装个客户端吧
[[email protected] ~]# rpm -ivhMySQL-Cluster-client-gpl-7.3.7-1.el6.x86_64.rpm
mysql12数据节点+SQL 节点配置文档
客户端装上
[[email protected] ~]# rpm -ivhMySQL-Cluster-client-gpl-7.3.7-1.el6.x86_64.rpm
把mysql11上 的配置文件弄过来吧
[[email protected] ~]# scp [email protected]:/etc/my.cnf /etc/my.cnf
SQL Cluster 初次启动命令以及用户密码更改调整：（请严格按照次序启动）
启动 mysql cluster
先启动顺序：管理结点服务 需要手动启动 ndbd 数据结点服务-》sql 结点服务
关闭顺序： 关闭管理结点服务 关闭管理结点服务后，nbdb 数据结点服务会自动关闭-》手动把 sql结点服务关了。
执行初次启动前请先确认将两台机器的防火墙关闭（service iptables stop 或者设定防火墙端口可通，两个端口即：通讯端口 1186、数据端口 3306 )
启动管理结点命令：

在同一台主机作为数据库节点上运行仲裁人
造成完整的集群关机的情况下主机发生故障。虽然报了一些警告，但是，我们已经执行成功了。
