CentOS 6.4 64位 搭建MySQL-Cluster 7.3.8 集群

准备：1、下载 MySQL-Cluster-gpl-7.3.8-1.el6.x86_64.rpm-bundle.tar

　　　　下载地址： http://mirrors.sohu.com/mysql/MySQL-Cluster-7.3/MySQL-Cluster-gpl-7.3.8-1.el6.x86_64.rpm-bundle.tar

　　　　解压：　　

[[email protected] files]# tar -xvf MySQL-Cluster-gpl-7.3.8-1.el6.x86_64.rpm-bundle.tar
MySQL-Cluster-test-gpl-7.3.8-1.el6.x86_64.rpm
MySQL-Cluster-shared-compat-gpl-7.3.8-1.el6.x86_64.rpm
MySQL-Cluster-client-gpl-7.3.8-1.el6.x86_64.rpm
MySQL-Cluster-embedded-gpl-7.3.8-1.el6.x86_64.rpm
MySQL-Cluster-server-gpl-7.3.8-1.el6.x86_64.rpm
MySQL-Cluster-devel-gpl-7.3.8-1.el6.x86_64.rpm
MySQL-Cluster-shared-gpl-7.3.8-1.el6.x86_64.rpm

　　   2、停掉原有mysql 删除开机自动运行 卸载原有mysql 相关（未有任何相关则忽略）

[[email protected] files]# service mysql stop Shutting down MySQL.. SUCCESS!

[[email protected] files]# chkconfig  mysql  off

[[email protected] files]# rpm -qa | grep MySQLMySQL-client-5.6.24-1.el6.x86_64MySQL-server-5.6.24-1.el6.x86_64MySQL-devel-5.6.24-1.el6.x86_64

[[email protected] files]# rpm -e --nodeps MySQL-client-5.6.24-1.el6.x86_64 MySQL-server-5.6.24-1.el6.x86_64 MySQL-devel-5.6.24-1.el6.x86_64

进行安装操作

[[email protected] files]# rpm -ivh MySQL-Cluster-server-gpl-7.3.8-1.el6.x86_64.rpm 

[[email protected] files]# rpm -ivh MySQL-Cluster-client-gpl-7.3.8-1.el6.x86_64.rpm

添加用户信息：

GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘123456‘ WITH GRANT OPTION;

　flush privileges ;

创建工作目录及文件配置：

[[email protected] var]# mkdir /var/mysql-cluster[[email protected] var]# mkdir /var/lib/mysql/data[[email protected] var]# mkdir /var/run/mysqld

　[[email protected] var]# chmod -R 1777 /var/lib/mysql
　[[email protected] var]# chmod -R 1777 /var/run/mysqld
　[[email protected] var]# chmod -R 1777 /var/lib/mysql-cluster

启动：

注：关闭防火墙设置(可待调试成功后重新开启防火墙仅开放用到的端口)，selinux 设为 disabled

顺序：管理节点->均衡节点->数据节点 （关闭时相反：数据节点 service mysql stop ->均衡节点 ndb_mgm -e shutdown）

[[email protected] mysql-cluster]# ndb_mgmd -f /var/lib/mysql-cluster/config.ini  //启动 管理节点 操作MySQL Cluster Management Server mysql-5.6.22 ndb-7.3.8 [[email protected] mysql-cluster]# ndbd --initial //均衡节启动 首次启动加 --initial 再次不需加 [[email protected] mysql-cluster]# mysqld_safe --defaults-file=/etc/my.cnf --explicit_defaults_for_timestamp & //启动数据节点

查看连接情况：

[[email protected] ~]# ndb_mgm

进入mysql出错处理：

mysqld_safe --skip-grant-tables &mysql -uroot -p>use mysql;>update mysql.user set password=PASSWORD(‘123456‘) where User=‘root‘ ; >flush privileges ;

or 

//在mysql 配置文件中加入以下一句话 ，重新启动输入 mysql 进入命令行修改密码

[[email protected] files]# vi /etc/my.cnf

[mysqld]skip-grant-tables

[[email protected] files]# mysql

出错：

ERROR 1820 (HY000): You must SET PASSWORD before executing this statement

>SET PASSWORD = PASSWORD(‘123456‘);
