Set Up the Internet Repository: RHEL/CentOS

This section describes how to set up a maprtech.repo file before adding an Internet repository.

Before upgrading your cluster software, you need to set up or update a maprtech.repo file. The baseurl properties of the maprtech.repo specify the URLs of the packages you want to install. To access the URLs for all release packages, see .

Change to the root user or use sudo.

Create a text file called maprtech.repo in the /etc/yum.repos.d/ directory with the following content, replacing <version> with the version of software that you want to install.


[maprtech]
name=MapR Technologies
baseurl=https://package.mapr.com/releases/v<version>/redhat/
     enabled=1
     gpgcheck=0
     protect=1
                            
[maprecosystem]
name=MapR Technologies
baseurl=https://package.mapr.com/releases/MEP/MEP-<version>/redhat
    enabled=1
    gpgcheck=0
    protect=1

If your connection to the Internet is through a proxy server, set the http_proxy environment variable before installation.
- Method 1:
```
http_proxy=http://<host>:<port>
export http_proxy
```
- Method 2: Set the value for the http_proxy environment variable by adding settings to the /etc/yum.conf file.
```
proxy=http://<host>:<port>
proxy_username=<username>
proxy_password=<password>
```
Download and install EPEL (Extra Packages for Enterprise Linux) if you use the mapr-metrics service; otherwise, skip this step.
- RHEL/CentOS 6.x:
```
wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -Uvh epel-release-6*.rpm
```
- RHEL/CentOS 7.0
```
wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
```
