Mysql Cluster Using Mysql NDB

Mysql Cluster using NDB(Network DataBase) provides a self healing mysql Cluster which provides a good performance. Mainly the Mysql Cluster Contains 3 Components ie using Management , SQL and Data parts. 

Here we will be configuring two Management and two Data/SQL (together in One server) for the HA. Once the configuration is completed we will have two end points to connect to te database so we need to keep an Load balancer in front of the SQL end points.

OS used is RHEL7
Selinux Enabed
Firewall Disabled

Management Server## Perform the Following steps in both the Management Server's. 

Install Needed Packages 

=================

yum install glibc.i686  ncurses-libs.i686 libstdc++.i686 libgcc.i686 -y


Make Directories and Download the Cluster Files
====================================

mkdir /usr/src/mysql-mgm
cd /usr/src/mysql-mgm
wget http://cdn.mysql.com/Downloads/MySQL-Cluster-7.4/mysql-cluster-gpl-7.4.7-linux-glibc2.5-i686.tar.gz
tar zxvf mysql-cluster-gpl-7.4.7-linux-glibc2.5-i686.tar.gz

cd mysql-cluster-gpl-7.4.7-linux-glibc2.5-i686
cp bin/ndb_mgm* /usr/bin/
chmod 755 /usr/bin/ndb_mgm*


mkdir /var/lib/mysql-cluster
vi /var/lib/mysql-cluster/config.ini

==========================================

chown mysql. /var/lib/mysql-cluster -R

To start the Management Service
========================
ndb_mgmd -f /var/lib/mysql-cluster/config.ini --configdir=/var/lib/mysql-cluster/

Data And SQL Server#Perform this on both of the Server's
==============================================

Install the needed Packages
====================
yum install libaio.i686 libaio-devel.i686 -y
yum install perl -y
yum -y install perl-Data-Dumper

Download the packages
cd /usr/local/
wget http://cdn.mysql.com/Downloads/MySQL-Cluster-7.4/mysql-cluster-gpl-7.4.7-linux-glibc2.5-i686.tar.gz
tar zxvf mysql-cluster-gpl-7.4.7-linux-glibc2.5-i686.tar.gz
mv /root/mysql-cluster-gpl-7.4.7-linux-glibc2.5-i686.tar.gz mysql
chown mysql. mysql -R
cd mysql

Initializing the database
scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data

cp support-files/mysql.server /etc/init.d/
chmod 755 /etc/init.d/mysql.server

cd /usr/local/mysql/bin
mv * /usr/bin
cd ../

vi /etc/my.cnf
============
[mysqld]
ndbcluster
# IP address of the cluster management node
ndb-connectstring=192.168.70.130,192.168.70.131
[mysql_cluster]
# IP address of the cluster management node
ndb-connectstring=192.168.70.130,192.168.70.131
============

mkdir /var/lib/mysql-cluster

cd /var/lib/mysql-cluster
ndbd --initial
/etc/init.d/mysql.server start

After this, secure the MySQL installation by running the appropriate script:

/usr/local/mysql/bin/mysql_secure_installation


Testing 
In the Management Node check the command ndb_mgm and check the status
