1.准备
mn:集群管理服务器用于管理集群的其他节点。我们可以从管理节点创建和配置集群上的新节点、重新启动、删除或备份节点。
db2/db3:这是节点间同步和数据复制的过程发生的层。
db4/db5:应用程序使用的接口服务器连接到数据库集群。
[root@java1 ~]# docker inspect -f ‘{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}‘ $(docker ps -aq)
/db5 - 172.17.0.6
/db4 - 172.17.0.5
/db3 - 172.17.0.4
/db2 - 172.17.0.3
/mn - 172.17.0.2
[root@java1 ~]#
2.mn安装
cd ~
wget http://dev.mysql.com/get/Downloads/MySQL-Cluster-7.4/MySQL-Cluster-gpl-7.4.10-1.el7.x86_64.rpm-bundle.tar
tar -xvf MySQL-Cluster-gpl-7.4.10-1.el7.x86_64.rpm-bundle.tar
yum -y install perl-Data-Dumper
yum -y remove mariadb-libs
cd ~

rpm -Uvh MySQL-Cluster-shared-gpl-7.4.10-1.el7.x86_64.rpm
Make sure there is no error.

db4/db5配置：

service mysql start
集群监控：

ndb_mgm> show
ndb_mgm -e "all status"
ndb_mgm -e "all report memory"
在db4或者在db5 测试集群：
mysql -u root -p
CREATE USER ‘root‘@‘%‘ IDENTIFIED BY ‘aqwe123‘;
select user, host, password from mysql.user;
GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY PASSWORD ‘*94CC7BF027327993D738E11...(Encrypted PASSWORD)‘ WITH GRANT OPTION;
最后的结果：
db5上也出现结果：
他们说问题多，主流的是mycat+mysql。明天再折腾。
