In the tutorial we will install MYSQL Network Database cluster (NDB) using 4 nodes.

Prerequisites

To complete this tutorial, you'll need the following:

  • 1 management node
  • 2 data nodes
  • 1 SQL node
  • mysql-cluster-gpl-7.6.7-linux-glibc2.12-x86_64

Naming

db2004.dfw.ppnet = SQL node

db2005.dfw.ppnet = 1st data node

db2006.dfw.ppnet= 2nd data node

db2008.dfw.ppnet= management node

Hardware/software requirements

I am running this in a VM environment. All nodes have 1Gb of RAM and 20GB of disk. To run this in a productions environment please refer to the MSQL NDB cluster documentation. 

free -h
              total        used        free      shared  buff/cache   available
Mem:           996M        254M        167M         10M        574M        578M

tmpfs           100M     0  100M   0% /run/user/2001

All 4 nodes are running Debian stretch 

lsb_release -a
No LSB modules are available.
Distributor ID:	Debian
Description:	Debian GNU/Linux 9.5 (stretch)
Release:	9.5
Codename:	stretch

Networking

IF you want to use the node FQDN you need to have a DNS server or update the /etc/hosts file; othewise, you can you the node IP address. For this tutorial We are gong to use the node FQDN.

  • SQL node
127.0.0.1       localhost
10.192.16.62    db2004.dfw.ppnet        db2004
  • 1st data node
127.0.0.1       localhost
10.192.16.63    db2005.dfw.ppnet        db2005
  • 2nd data node
127.0.0.1       localhost
10.192.16.64    db2006.dfw.ppnet        db2006
  • management node
127.0.0.1       localhost
10.192.16.61    db2008.dfw.ppnet        db2008

Installation

The link to download the NDB cluster is:

https://dev.mysql.com/get/Downloads/MySQL-Cluster-7.6/mysql-cluster-gpl-7.6.7-linux-glibc2.12-x86_64.tar.gz'

This needs to be done on all nodes or you can download it on one node and just copy it to the other nodes by using scp

Download

login to each node and create a repertory called files under /tmp/ 

cd /tmp
mkdir files

Now change to the files repertory we just create 

cd files

Download the NDB cluster now 

wget https://dev.mysql.com/get/Downloads/MySQL-Cluster-7.6/mysql-cluster-gpl-7.6.7-linux-glibc2.12-x86_64.tar.gz'
