Install Myriad

About this task

The Myriad installation is a manual installation where the Mesosphere repository is installed before the MapR Mesos and Myriad packages.

Procedure

Add the Mesosphere repository to each node in the cluster:
NOTE: When installing the MapR packages for Mesos and Myriad, do not use the rpm -ivh command to install these packages because the dependencies do not get installed.
On RedHat6 / CentOS6
```
sudo rpm -Uvh http://repos.mesosphere.io/el/6/noarch/RPMS/mesosphere-el-repo-6-2.noarch.rpm
```
On RedHat7 / CentOS7
```
sudo rpm -Uvhhttp://repos.mesosphere.io/el/7/noarch/RPMS/mesosphere-el-repo-7-1.noarch.rpm
```
On Ubuntu
Setup:
```
sudo apt-key adv 
--keyserver keyserver.ubuntu.com 
--recv E56151BF DISTRO=$(lsb_release -is | tr '[:upper:]' '[:lower:]')
CODENAME=$(lsb_release -cs)
```
Add the repository:
```
echo "deb http://repos.mesosphere.io/${DISTRO} ${CODENAME} main" | sudo tee /etc/apt/sources.list.d/mesosphere.list
sudo apt-get -y update
                                
```
NOTE: On Ubuntu, it is recommended that you install Marathon version 0.10.1 for Java 7 compatibility. The latest Marathon version (0.11 and later) only supports Java 8. For example, apt-get install marathon=0.10.1-1.0.416.ubuntu1404

On the Mesos master node, install (as a minimum) the following MapR Mesos and Myriad packages:


mapr-core 
mapr-fileserver 
mapr-cldb 
mapr-webserver 
mapr-mesos-slave 
mapr-mesos-master 
mapr-mesos-marathon 
mapr-myriad-executor 
mapr-myriad-scheduler

On RedHat / CentOS

yum -nogpgcheck install <package> <package>  ...

On Ubuntu

apt-get install  <package> <package> ...

Install MapR Zookeeper on its master node:
The MapR mapr-zookeeper package can be installed on any node that is designated as its master. For example, on the Mesos master node:
```
mapr-zookeeper
```
(optional) Install Mesos-DNS on its master node:
The Mesos-DNS mapr-mesos-dns package can be installed on any node that is designated as its master. For example, on the Mesos master node:
```
mapr-mesos-dns
```

On the Mesos slave nodes, install (as a minimum) the following MapR Mesos and Myriad packages:


mapr-core 
mapr-fileserver 
mapr-mesos-slave 
mapr-myriad-executor 
mapr-myriad-scheduler

Small Cluster Installation

The following example shows an installation on a CentOS6 operating system, a three (3) node cluster where one node is the master node for Mesos, Mesos-DNS, MaprR CLDB, and MapR Zookeeper, and two nodes are Mesos slave nodes.

On the master node, add the Mesosphere repository and install the following packages:


sudo rpm -Uvh http://repos.mesosphere.io/el/6/noarch/RPMS/mesosphere-el-repo-6-2.noarch.rpm

yum -nogpgcheck install
mapr-core mapr-fileserver mapr-zookeeper mapr-cldb mapr-webserver 
mapr-mesos-dns mapr-mesos-slave mapr-mesos-master mapr-mesos-marathon mapr-myriad-executor mapr-myriad-scheduler

On two slave nodes, add the Mesosphere repository and install the following packages:


sudo rpm -Uvh http://repos.mesosphere.io/el/6/noarch/RPMS/mesosphere-el-repo-6-2.noarch.rpm

yum -nogpgcheck install
mapr-core mapr-fileserver mapr-mesos-slave mapr-myriad-executor mapr-myriad-scheduler
