Configuring MapR-5.0.0 cluster on RHEL-6.7 OS.

Here I am adding very basic steps to follow configuring  MapR-5.0.0 cluster on Redhat-6.7 operating system.

Please follow below steps for  for configuring.

Note:

Here We have 2 disks in each node.

Cluster Information:

Cluster Version : MapR-5.0.0

OS version : RHEL-6.7

Number of nodes : 3 nodes.

Login as :mapr/mapr
(Note: Assuming that the basic hardware requirements meet the cluster to configure.)

Steps:

Step 1:

Add the hostnames and ipaddress of all the cluster nodes in /etc/hosts file on each node.

$sudo vi /etc/hosts

172.20.10.10 host10

172.20.10.11 host11

172.20.10.12 host12

Step 2:

Adding virtual disks info. in file called disks.txt to each node.

$sudo vi /tmp/disks.txt

xvdb

xvdc

Step 3:

Adding a group and a User to the each node

$sudo groupadd -g 5000 mapr

$sudo useradd -g 5000 -u 5000 mapr

Step 4:

Changing the SELINUX parameter=pemissive in each node

$sudo vi /etc/selinux/config

SELINUX=pemissive

Step 5:

Disable the iptables(disable firewall permanently) using below command in each node.

$sudo iptables -F

or use below two commands to disable permanently in each node.

$chkconfig iptables off

$service iptables stop

Step 6:

Add the MapR version and ecosystem repos to maprtech.repo file in each node

$sudo vi /etc/yum.repos.d/maprtech.repo

[maprtech]

name=MapR Technologies

baseurl=http://package.mapr.com/releases/v5.0.0/redhat/

enabled=1

gpgcheck=0

protect=1

[maprecosystem]

name=MapR Technologies

baseurl=http://package.mapr.com/releases/ecosystem-5.x/redhat

enabled=1

gpgcheck=0

protect=1

Step 7:

Use below rpm packages to download on each node

$sudo wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

Step 8:

Install the above downloaded rpm.

$sudo rpm -Uvh epel-release-6-8.noarch.rpm

Step 9:

import the key

$sudo rpm --import http://package.mapr.com/releases/pub/maprgpg.key

Step 10:

Install java-1.7.0.openjdk-devel , if not installed.

$sudo yum install java-1.7.0-openjdk-devel

Step 11:

Install the mapr-core packages(eg: mapr-fileserver,mapr-cldb,mapr-zookeeper etc... required services on each cluster)

$sudo yum install mapr-fileserver

$sudo yum install mapr-cldb mapr-zookeeper

Step 12:

List out the CLDB's ,Zookeeper's insta nodes and then run the configure.sh which is present in "/opt/mapr/server/" folder on each node.

List of CLDB installed nodes : 172.20.10.10,172.20.10.11

List of Zookeeper installed Nodes: 172.20.10.10,172.20.10.11,172.20.10.12

$sudo server/configure.sh -C 172.20.10.10,172.20.10.11 -Z 172.20.10.10,172.20.10.11,172.20.10.12 -N 3Node-MapR-5.0-Cluster

Step 13:

Add the disks.txt file each node

$sudo server/disksetup -F /tmp/disks.txt

Step 14:

use below command to check for all started commands.

$ sudo maprcli node services -columns svc
