The operating system is CentOS 7-64bit.
5 CentOS servers or virtual machines. I will use the host name and IP address as follows:
Management node
MySQL1.test.com = 192.168.1.51
SQL node
MySQL2.test.com = 192.168.1.52
MySQL3.test.com = 192.168.1.53
data node
MySQL4.test.com = 192.168.1.54
MySQL5.test.com = 192.168.1.55
Download the installation package 
https://dev.MySQL.com/get/Downloads/MySQL-Cluster-7.4/MySQL-Cluster-gpl-7.4.18-1.el 7. x86_64.rpm- bundle.tar

Management node installation settings
Download the software package and unzip
[root@MySQL1 ~]# wget wget http://dev.MySQL.com/get/Downloads/MySQL-Cluster-7.4/MySQL-Cluster-gpl-7.4.10-1.el7.x86_64.rpm-bundle.tar
[root@MySQL1 ~]# mkdir MySQL

Install the necessary software
[root@MySQL1 ~]#yum -y install net-tools
[root@MySQL1 ~]#yum -y install perl-Data-Dumper
Install to
see if MySQL or mariadb is already installed
[root@MySQLcluster1 MySQL]# rpm -qa |grep mariadb*

up the configuration folder
[root@MySQL1 MySQL]# mkdir -p /var/lib/MySQL-cluster 
set up the configuration file
according to the following steps to set and save
[root@MySQL1 MySQL]# cd /var/lib/MySQL-cluster

Start the management node and view the status
Start the management node
Next, use the following command to start the management node:

view status
[root@MySQL1 MySQL-cluster]# ndb_mgm
