Step 3: Install MapR Service Packages

The installation process will vary based on the location of your packages and the configuration of your cluster.

Install services based on your cluster plan and service layout.

NOTE: Before installing MapR software using the published packages, make sure that you have reviewed the list of known vulnerabilities in Security Vulnerabilities. If a vulnerability applies to your release, contact your MapR support representative for a fix, and apply the fix immediately, if applicable.

List of Packages by Mode

The following table lists the MapR core packages to install on cluster nodes:

Installation	YARN
Packages to install on all [compute] cluster nodes	`mapr-fileserver`
Packages to install on designated cluster nodes	`mapr-cldb` `mapr-zookeeper` `mapr-nfs` `mapr-webserver` `mapr-apiserver` `mapr-gateway` `mapr-resourcemanager` `mapr-nodemanager` `mapr-historyserver` `mapr-timelineserver`
Package to install on client machines that run hadoop commands that are not already part of the cluster	`mapr-client`

WARNING: This table is a rough guide and does not include the additional packages required for internal dependencies or Hadoop ecosystem components.

Install the packages based on a thorough plan. For example cluster designs, see Example Cluster Designs.

To install MapR, select one of the installation methods in the subsequent topics, depending on your operating system.

Installing from a Repository

Before installing from the repository, change to the root user or use sudo.

On RedHat, CentOS, or Oracle Linux, use the yum command to install the services that you want to run on the node.
Syntax and Example
```
yum install <package_name> <package_name> <package_name> 
```
```
yum install mapr-fileserver mapr-nodemanager
```
On SUSE, use the zypper command to install the services that you want to run on the node.
Syntax and Example
```
zypper install <package_name> <package_name> <package_name>
```
```
zypper install mapr-fileserver mapr-nodemanager
```
On Ubuntu, use the apt-get commands to update the Ubuntu package cache and install the services that you want to run on the node.
1. Update the Ubuntu package cache:
```
apt-get update 
```
2. Install the services:
  Syntax and Example
```
apt-get install <package_name> <package_name> <package_name> 
```
```
apt-get install mapr-fileserver mapr-nodemanager
```

Installing from a Local Repository

Before installing from the repository, change to the root user or use sudo.

On RedHat, CentOS, Oracle Linux, or SUSE, use rpm command to install the appropriate packages for the node:
1. Change the working directory to the location where the rpm package files are located.
2. Install the services:
  Syntax and Example
```
yum install <package_file> <package_file> <package_file>
```
```
yum install /path/to/mapr-core-<version>.x86_64.rpm mapr-cldb-<version>.x86_64.rpm \
              mapr-resourcemanager-<version>.x86_64.rpm mapr-webserver-<version>.x86_64.rpm \
```
  NOTE: Replace <version> with the exact version string found in the package filename.
On Ubuntu, use the dpkg command to install the appropriate packages for the node.
1. Change the working directory to the location where the deb package files are located.
2. Install the services:
  Syntax and Example
```
dpkg -i <package_file> <package_file> <package_file>
```
```
dpkg -i mapr-core-<version>.x86_64.rpm mapr-cldb-<version>.x86_64.rpm \
              mapr-resourcemanager-<version>.x86_64.rpm mapr-webserver-<version>.x86_64.rpm \
```
  NOTE: Replace <version> with the exact version string found in the package filename.

Installing from Package Files

When you install from package files, you must manually pre-install any dependency packages in order for the installation to succeed. Most MapR packages depend on the package mapr-core. Similarly, many Hadoop ecosystem components have internal dependencies. See Packages and Dependencies for MapR Software for details.
