安装
查看是否已经安装MySQL 或mariadb
[root@MySQLcluster1 MySQL]# rpm -qa |grep mariadb*
[root@MySQL1 ~]# rpm -e --nodeps mariadb-libs-5.5.44-2.el7.centos.x86_64

管理节点监视群集
查看群集状态
[root@MySQL1 ~]# ndb_mgm
ndb_mgm> show

这样的话群集就完成了
不登陆数据测试状态
[root@MySQL1 ~]# ndb_mgm -e "all status"
[root@MySQL1 ~]# ndb_mgm -e "all report memory"

修改密码并测试
修改密码
查找密码
登陆到sql node1上查看密码，之前安装的时候已经提醒密码在.MySQL_secret里

[root@MySQL2 ~]# cat .MySQL_secret

初始化MySQL更改MySQL密码
[root@MySQL2 ~]# MySQL_secure_installation

修该登陆密码

删除所有用户

拒绝root远程登陆 选择no

是否删除test数据库 no

重新导入权限配置

添加账号并赋予远程登陆读写数据库权限
[root@MySQL2 ~]# MySQL -uroot -pP@ssw0rd

新建一个外部账号用于远程登陆
MySQL> CREATE USER ‘stonehu‘@‘%‘ IDENTIFIED BY ‘P@ssw0rd‘;

查看用户权限表
MySQL> select user, host, password from MySQL.user;

并从远程节点授予新的stonehu用户读写权限
MySQL> GRANT ALL PRIVILEGES ON . TO ‘stonehu‘@‘%‘ IDENTIFIED BY PASSWORD ‘*8232A1298A49F710DBEE0B330C42EEC825D4190A‘ WITH GRANT OPTION;
